A filter unit is disclosed that increases solids loading capacity, decreases specific flowrate during filtration, and improves backwash effectiveness. A flow shaping plate and/or flow diverting member are used to reduce flow entrance effects during reverse, backwash flow through the filter unit.

Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader having a triangular shape with straight sides, or concave sides or convex sides can split incoming water to pass into dual screen filtration systems. Additionally, an upwardly angled debris ramp above a downwardly angled screened defector can be located on both sides of the flow spreader to help direct debris and trash into dual screened boxes. The system can also include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and hydroslide water pressure lines with spray heads for cleaning debris on a sloped floor.

A sensor control system of a food processing system includes a logic processor operatively coupled to an electrode. The logic processor is configured to receive a sensor signal from the electrode, the electrode configured to collect the sensor signal from water used within the food processing system, process the sensor signal to determine a chemical measurement of the water, and generate an electrochemical cleaning control signal for the electrode to interact with the water to electrochemically clean the electrode based upon a user input signal.

A system for removing particulates of a fissile material includes first and second filtration paths. A first filter and a first valve are disposed in the first filtration path. A second filter and a second valve are disposed in the second filtration path. The first valve and the second valve are configured to switch between a dual open state and a mixed open/closed state. During the dual open state, the first valve and the second valve axe open to permit concurrent flows of the effluent gas through the first and second filtration paths. During the mixed open/closed state, one of the first valve and the second valve is open while the other of the first valve and the second valve is closed to permit the particulates on a corresponding one of the first filter and the second filter to be dislodged by a countercurrent flow of a purging gas.
