DESCRIPTION OF RECYCLATRON TECHNOLOGY
1. INTRODUCTION
The following describes the Recyclatron separation systems It includes a discussion of the standard “tank-based” systems and an extensive discussion of the control system functionality.
Although the term “separation system” basically refers to an installation that incorporates both Recyclatron and Separator Pack (FDR)and the full control system, parts are optional.
The control system is based on standard units (micro-processor system and terminal) and software written in C. Since the functionality of the control system is limited to the functionality of the separation systems, its scope is limited. On the other hand no two applications will be identical and the system design should be flexible enough to meet any application without the requirement of software modification.
The flexibility will be achieved at three different levels:
a. User accessible settings.
b. Configuration features, accessible to those that have been introduced to the technology.
c. A modular software structure, resulting in a library of functions that can be included in the software as required.
ad.a. Examples of settings that can be changed at this level are time settings for flush cycles and setpoints for low-level pump or alarm controls.
ad.b. This level opens the possibility to change parameters that are essential to control functions. Examples are parameters for analog input signal scaling and filtering and specific calibration functions.
ad.c. At this level the functionality of the total system is determined. Specific functions can be included or excluded from the application, depending on the scope of supply. Examples are flow-calculation based on level measurement, and data-logging.
2. SYSTEM OVERVIEW
The systems are designed to treat aqueous media in order to remove oil, grease and comparable pollutants, if applicable together with suspended solids. The system comprises of four main items, the tank to process the medium, a Recyclatron unit, a Separator Pack filter and a control system. (FDR)
The systems are designed to operate at maximum performance at all times, independent from the process conditions. There is no process that is so unpredictable and variable as waste water treatment. No company plans and carefully controls its waste water production within strict limits. They all try to minimize the waste water production and pollution, but that sooner adds to the variations in process parameters. Often amount of waste water, nature of the pollution and pollutant concentrations are totally or mainly dependent on incidents. Occurrences that are not planned, not even desired, and absolutely unpredictable.
The separation systems are designed to meet these harsh conditions and to maintain performance at all times.
A number of standard tanks are available for different capacities. Furthermore special design units can be built to meet clients specifications. It is also possible to incorporate the entire functionality of the separation system into existing separators or tanks.
Items that can be varied per application are:
- Size and shape of the tank
- Implementing Separator Packs or not. In some applications there may be no need to use Separator Packs. (FDR)
- The number of Separator Packs modules. Again depending on h severe the requirements are, more or less modules can be installed.
- The controller options that are implemented.
2.1 SEPARATION SYSTEM
The minimal configuration of a separation system comprises of a tank with a Recyclatron unit installed, incorporating recirculation and continuous discharge of pollutant. This minimal configuration can be upgraded with Separator Pack filters to greatly improve the purification process.
Additional functions can be incorporated into the system like:
- buffering of removed pollutant
- automatic transfer of removed pollutant to storage facilities
- flow measurement and control
- temperature measurement and control
- buffering and suppletion of purified water
- influent/effluent pump transfer control
- pH measurement and neutralization
1. Normally the tanks are made of carbon steel with a three layer coating. However, stainless steel is also possible. Shape and size of the tank are designed to create optimal performance. This unit is specifically designed to treat waste water with high solids loading.
2. In the design consideration is given to the production process. Bending and folding of metal has been given preference over welding, so that the product meets the high quality standards that ensure a long life-cycle.
3. Flow deflection device.
An important issue is the flow conditions inside the unit. Turbulence and dead corners must be avoided and laminar flow is essential. This requires special provisions that are also dependent on the type of waste water and nature and concentration of the pollutant.
4. Effluent outlet.
In this tank is a buffer capacity for purified water is incorporated, so that fluctuations in the usage of this water can be bridged, and unnecessary suppletion of fresh water is prevented.
5. Recirculation compartment.
The skim flow passes along the surface in the processing area through the Recyclatron unit and into the recirculation compartment.
Outlets for the oil buffer tanks
Each buffer has two outlets. One is to regularly remove the separated oil, the other to drain the buffer and that way remove sludge and other pollution that has been separated with the oil. This way the separated oil or grease can be decanted and split into a relatively clean portion, possibly suitable for reuse, and a small, strongly polluted portion.
Buffer tanks for clean and polluted oil/grease.
The larger systems have two buffer tanks. Buffer is for the oil that is separated from the waste water by the Recyclatron unit. This is the clean fraction that readily floats on water. Buffer is for material that accumulates at the surface in the recirculation compartment. Adjustable weir can be used to skim off this material and collect it in buffer.
6. Adjustable weir to skim off material that accumulates at the surface in the recirculation compartment. Almost in all situations the separation system will remove material from the aqueous flow that does not readily float on water. This can be solids, mixed with oil or grease, or floating matter with considerable amounts of water dispersed in it. It will therefore pass through the Recyclatron unit into the recirculation compartment. The design of this compartment is such that this material accumulates here and either settles to the bottom or floats to the surface. In the latter case it can be removed manually or automatically, using weir.
7. Recirculation pump.The recirculation pump returns the water form the recirculation compartment to the inlet at the beginning of the processing area.
8. Recirculation pump suction pipe.Mounting is done in such a way that no floating pollutants are drawn away, so that these can accumulate in the recirculation compartment.
9. Adjustable effluent weir.
The effluent weir controls the liquid level in front of the Recyclatron unit. When the skim-control option for the controller is selected, the control system will adjust this weir using a lineator.
This is the most essential control function in order to have the separation system respond to any fluctuation in the process conditions.
10. Drains. A number of drains are installed to allow removal of accumulated pollutants during normal operation.
11. Process area/Separator Pack filter (FDR)
The process area can be equipped with one or more Separator Pack modules
12. Flow deflection devices.
Are installed to guide any material that flows on the surface in the process area to the Recyclatron unit.
13. Baffle plate for sludge retention/flow deflection.
2.2 MAN-MACHINE INTERFACE
The separation systems are designed for unattended operation under the most variable process conditions. The controller, which is essential in this respect, functions independent from any operator actions, but does have a user interface to present actual and historic data to the operator and to enable changing parameters.
Interface between controller and user is by means of an intelligent interface panel with alpha/numeric keys, function keys and a 2 by 20 character display.
The display is of the electro-luminicence type which lights up brightly and can be read without problems even in the dark. To view messages or historic data the user can scroll the display. Function keys are used to select the main functions available.
The system functions independently and does not require any attention from operating personnel. Only in case of a major malfunctioning maintenance will be required, in which case an alarm will be sounded.
Through a number of menus the user can select the function he chooses. In normal mode the unit will display the major parameters of the process. If left idle the system will automatically change back to this normal mode.
Changing parameter can be protected by passwords.
2.3 CONTROL SYSTEM
The controller is micro-processor based and of a modular design which makes it possible to extend the I/O as required. The software is written in C and is also modular. In any application only those software modules that are necessary will be linked into the application program. The application program is stored in on-board ram.
The system is developed as a fully automated unit, designed for unattended operation. The main task of the controller is to monitor and control the purification process. The software is written as a set of intelligent control blocks. Each of these blocks has functions to monitor the operation of the system and to dynamically fine-tune settings for the controller response. Use is made of “fussy-logic” features and self-learning routines.
This means that the initial set-up of the system can be kept simple and takes little effort. In time the system will fine-tune itself to the specific process conditions that characterize the application.
The user has the possibility to change settings relevant to the control functions as well as to force parameters. overruling the automatic fine-tuning.
The second task of the controller is to inform the user about operation and performance of the system. Three levels for user-information are implemented, alarming the user about malfunctioning, presenting data on the actual status of the process and the presentation of historic data. The user can respond to alarms and messages and can select the data that is to be presented.
2.4 CONTROLLER-PROCESS INTERFACE
The interface between controller and process is by means of its I/O. In the minimum configuration the system has 12 digital inputs, optically isolated, 7 relay outputs and 12 analog inputs.
3. SEPARATION SYSTEMS DRAWINGS:
4. CONTROL FUNCTIONS
The functions that are available for the application program comprise of a large number of standard software modules from which the required selection can be ;made. This is done during the design and fabrication of the system, and cannot be done by the user. It is possible to later upgrade the software to include new functions. The following software modules are currently available:
MEASUREMENT This is a standard function for handling analog signal. In addition to reading and scaling the measurement, corrections and filtering are possible. Further more average values and rate of change data can be produced.
This module is used to measure level, flow, temperature, pH, etc.
SETPOINT This function enables linking of setpoints to measured values and drive outputs with the results. It is also used to drive other control functions.
DEVICE ON/OFF This module drives a digital output on an on/off basis. It is used for pump control, heating, suppletion of water, PH correction etc. Included in the module are interlock functions that enable inhibiting the output.
This module is used for the recirculation pump, water transfer pumps, oil transfer pumps, etc.
SKIM CONTROL This function includes level measurement in the recirculation buffer and the control functions for the alienator by which the overflow weir is adjusted. This module controls the response of the system on changes in the following process conditions:
· Changes in the flow through the separation system.
· Changes in the amount and nature of the floating pollutants.
· Fouling of the system.
The module is self learning. It monitors the behavior of the overall system in response to control actions and the fine-tunes these actions to obtain optimal control.
RECYCLATRON
FLUSHING Fouling of the Recyclatron unit will cause water to be skimmed of with the floating matter. This can easily be prevented by regularly flushing the Recyclatron unit with water. This module takes care of the flushing.
The module is self learning. It monitors the effects of the flushing on other control actions and checks for periodicity. Based on the result it can adjust the interval of flushing.
INTERFACE I This module provides the support for the user interface for the basic functions. It handles alarms and messages and displays measured values. Also incorporated are the functions to change accessible parameters.
INTERFACE II This module adds more enhanced functions to the user interface. It allows for storage and retrieval of historic data. Furthermore it extends the functions to retrieve and change parameters, with password protection.
Each of the control functions specified are detailed further in the next paragraphs.
4.1 MEASUREMENT
Analog signals can be voltage, milliamp or resistance type. The actual signal, available to the application software is converted to the measured property. To this purpose a number of transactions are necessary. Furthermore secondary data is derived from the measured value. Analog signals are processed at regular intervals, but the interval is dependent on the application program.
The following transactions can be applied to the initial signal.
Step 1. Conversion of internal signal to measured signal.
The signal, available to the software, is converted to voltage, milliamp or resistance value. This includes an offset and span correction.
Step 2. Conversion of measured signal, obtained in Step 1, to measured value. To this purpose the system uses parameters TOP-SCALE and BOTTOM-SCALE. These parameters are adjustable, but will normally be set only during initial testing of the system. They are accessible with INTERFACE II module.
Step 3. Filtration of the measured value to filtered value.
It is normal that process variables fluctuate slightly in time, although there is not really a change in the process conditions. In that case it will be necessary to filter the measured value. The filter function in this module uses two parameters, STEP and BAND.
The parameters STEP and BAND can be adjusted, which is normally done during initial testing of the system.
INTERFACE II gives access to these parameters.
With parameter FINE-TUNE this module can be ;made to automatically fine tune the setting for BAND and STEP. If enabled it will use historic data to determine what normal fluctuation rates are in a specific application.
Step 4. Calculation of average value.
For some process variables it may be useful to also have an average value available. to this purpose up to the last 25 measured values are stored and the average is calculated. This function is controlled by two parameters, NUMBER and INTERVAL. NUMBER specifies the number of measured values that is stored to calculate the average, INTERVAL specifies at which interval a new measured value is stored and an average is calculated.
Step 5. Calculation of rate-of-change
To optimally control the process, for some measurements the rate of change is important. To calculate this value the module stores a time stamp each time the analog signal is processed. With the time elapsed between two processing cycles, and the difference between old and new measured value, the rate of change is calculated.
4.2 SETPOINT
This module can be linked to any analog input signal. The module compares the SETPOINT parameter with the measured value, of analog input defined by parameter IN, and uses parameters OUT and STATUS to control a digital output. OUT specifies which output. If no output is specified, only an internal flag is set, which can be used by other program modules. This module uses the measured value which is available after Step 3 of the MEASUREMENT module.
The SETPOINT parameter can be changed using program module INTERFACE I, the other parameters can only be changed using INTERFACE II.
4.3 DEVICE ON/OFF
This module provides on/off control for various types of equipment. It is most commonly used for pump on/off control functions. Parameters ON and OFF specify the status signals that determine whether output OUT is to be switched on or off. If parameter INTERLOCK is specified, the output will only be energized if INTERLOCK is high.
4.4 SKIMMING CONTROL FUNCTION
The skimming control function is the most important function of the controller. This function adjusts the positions of the effluent weir, which effectively changes the neutral liquid level in front of the Recyclatron unit.
4.4.1 CONTROL PHILOSOPHY
In this discussion the following terms have the meaning detailed hereafter:
System level: The level in front of the Recyclatron unit
Neutral liquid level: The system level with no floating matter present
Recyclatron flow: The water flow through the Recyclatron unit
System flow: The flow through the system which equals the influent flow and the effluent flow
Recirculation flow: The flow generated by the recirculation pump
Recirculation level: The level in the recirculation buffer
Effluent weir: The weir that controls the Recyclatron level. The system flow flows over this weir into the effluent compartment.
The input for the skimming control function is the recirculation level. The output is a signal to an actuator that adjusts the height of the effluent weir. Based on the input signal the controller will adjust the height of the effluent weir in order to maintain a constant, pre-set, recirculation level.
If this level drops the controller will raise the effluent weir. This causes the system level to rise, resulting in an increase in the Recyclatron flow which subsequently raises the recirculation level.
If this level rises above the preset value, the controller will lower the effluent weir and thereby the system level. this will reduce the Recyclatron flow which will cause the recirculation level to drop.
With this control function, the system can respond to changes in two different process conditions:
a. Changes in the influent flow
b. Changes in the amount and density of the floating matter.
The control function responds to the two process parameters in the following sense:
ad.a Variations in the influent flow will cause the system level to change, which affects the Recyclatron flow and subsequently the recirculation level.
If the flow increases, the system level will rise, causing the Recyclatron flow to increase and the recirculation level to rise.
The control function will lower the effluent weir to correct this.
If the flow drops, the system level will drop, causing the Recyclatron flow to decrease and the recirculation level to drop.
The control function will raise the effluent weir to correct this.
The control function stabilizes the flow through the Recyclatron unit with normal levels inside the Recyclatron unit.
ad.b Variations in amount and density (composition) of the floating matter will affect the Recyclatron flow. The thickness of the water layer, passing over the first weir (nose) of the Recyclatron unit, relates directly to the flow through it. A floating layer on the surface will cause this layer to become thinner. This is due to the fact that such a floating layer extends below the neutral liquid level.
- A thicker floating layer will extend further below the neutral liquid level and result in a thicker water layer.
- A higher density (emulsions) will cause the floating layer to extend further below the neutral liquid level which also results in a thinner water layer.
- Solids and semi-solids (debris) will cause partial blockage of the Recyclatron flow.
The influence of the nature and amount of floating matter on the Recyclatron flow results in variations in the recirculation level. The control function corrects this by adjusting the effluent weir.
Effectively the control function will raise the neutral liquid level in front of the Recyclatron unit so that floating matter is carried high enough into the unit.
The control function stabilizes the Recyclatron flow with normal water levels inside the Recyclatron unit and increased floating layer level.
The control function, by its nature, will respond to changes in the following system conditions:
c. Restrictions in the passage of the main flow.
d. Changes in the recirculation flow.
e. Obstructions in the Recyclatron unit.
ad.c. The pollutants, carried into the separation system with the influent flow, will deposit on all wetted parts of the system. Most particular this will be the case n the Separator Pack filter. This deposition of pollutants creates additional restriction for the flow through the Separator Pack filter. The result is an increase in the system level above the filter (in front of the Recyclatron unit) and in turn rising of the level in the recirculation compartment.
Other places where obstruction due to deposited pollution can occur are the channels and siphons the system flow has to pass before it reaches the effluent weir. the control function responds by lowering the effluent weir, which increases the level drop over the obstruction, restoring the system flow. In the channels and siphons the increased velocity will slow down and limit the deposition of pollutants. There will be no need to clean these areas. In the Separator Pack filter the increased level drop maintains the required flow through it until the filter is flushed.
ad.d. The deposition of pollutants will also occur in the recirculation line. Depending on the type of recirculation pump, this may cause the recirculation flow to drop, which would cause the recirculation level to rise.
The skimming control function adjusts the effluent weir to reduce the Recyclatron flow to match the reduced recirculation flow.
In case of an increase in the recirculation flow, due to further opening of a throttle valve, or increasing the capacity of the pump, the recirculation level will drop. The control function will raise the effluent weir in order to increase the Recyclatron flow to match the recirculation flow.
ad.e. Finally pollutants will also deposit inside the Recyclatron unit. This will directly obstruct the Recyclatron flow, so that the recirculation level drops. The control function will raise the effluent weir to increase the Recyclatron flow.
4.5 RECYCLATRON CONTROL FUNCTION
Control function to flush Recyclatron unit. Function must allow for flushing in more than one section.
4.6 SEPARATOR PACK CONTROL FUNCTION
Control function should allow for flushing in more than one segment.
