Extras: Notch Filter - Control Tutorials for MATLAB and ...

One way to control this system is to design a controller with zeros near the undesirable, lightly-damped poles of the plant. These zeros can attenuate the effect of these poles. The dominant closed-loop poles of the system can then be placed in a more desirable position. Such a controller is called a notch filter.

White Paper Water Treatment Process Automation Control

Aug 02, 2007 · ment plant operator in the control of the treatment process. Process automation can be separated into two types - continuous (or analog), and sequential (or logical). Flow control is an example of continu-ous or analog control, while the sequencing of valves in the backwash of a filter is logical control.

The filter level will vary based on how long the filter has been on online and on how much water the plant is treating. After about 40 to 120 hours of runtime, depending on water quality, the filter must be backwashed. During the filter backwash, hundreds of thousands of gallons are normally used in a complex series of controlled steps.

IGR Used to Control Filter Fly Infestation | WaterWorld

To flood a filter, the effluent side of the filter is plugged to allow chlorinated wastewater to fill the basin for 24 hours. The filter fly adults drown or leave the beds, while millions of the pupa and larva float to the top of the filter to be skimmed. Flooding the filter depopulates the filter bed and helps control the rate of adult production.
