A dip tank and recycling system for applying antimicrobial solution to food items, including a dip tank having a bottom and sides, and holding a liquid antimicrobial solution. A conveyor to convey food items through the tank passes through the liquid antimicrobial solution held in the tank such that food items conveyed on the conveyor are dipped in the liquid antimicrobial solution. At least two discharge nozzles spray fresh antimicrobial solution into the tank. The discharge nozzles are located in the sides of the tank, and are positioned above the level of the conveyor but below an expected top level of the liquid antimicrobial solution contained within the tank such that food items conveyed on the conveyor are agitated by the force of the spray from the discharge nozzles. The spray from the discharge nozzles causes unstacking of items on the conveyor, producing an even application of the antimicrobial solution.

A pool cleaner that may include a drive mechanism for moving the pool cleaner; a housing that has a first fluid opening and a second fluid opening; a filtering unit that comprises a filter enclosure and a filtering element; a fluid flow mechanism for inducing a flow of fluid through the filtering element in a first direction during a filtering process and for inducing a flow of the fluid through the filtering element at a substantially opposite direction during a backwash process; and a debris trap that is configured to receive debris from the filtering element during the backwash process and to substantially prevent the debris from exiting the debris trap during the filtering process.

A filtration device can be configured to form filter cakes and filtrate by filtering solid particulates from a slurry. Some embodiments of the filtration device can utilize a mechanism that is configured to separate the formed filter cake from a disc sector for subsequent processing of the solid particulates of the filter cake and/or the formed filtrate. Embodiments of the filter device and/or mechanisms of the filter device as well as methods of making and using the same can help provide improvements in operational efficiency for processing operations in which solids are to be filtered from a slurry.

A rotary disc filter is provided with an integrated backwash and chemical cleaning system. In one mode of operation, backwash is directed through a control valve to one or more nozzles for spraying the backwash onto the filter media forming a part of a rotary disc filter. In a second mode, a chemical cleaning mode, the pump directs backwash through an eductor that induces a chemical into the inductor which is mixed with the backwash to form a backwash-chemical mixture that is sprayed onto the filter media. A control system is used in conjunction with the backwash and cleaning systems to monitor process information and/or filter media properties and to determine when to perform backwashes and regenerative cleanings in order to optimize the performance of the filter system.

Systems and related methods for purging air burst supply piping of accumulated water prior to delivering pulses of pressurized air to an interior of a screen intake through the air burst supply piping. The systems and methods can include a purge compressor delivering a purging air supply at a head pressure slightly above a head pressure of water in the air burst supply piping, wherein the head pressure of the water is equivalent to a depth at which the intake screen. The system and methods can also include a purge line arranged in a parallel orientation to an air burst supply line, wherein both the purge line and the air burst supply line are operably coupled to a pressurized air tank.
