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.

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 rotating irrigation screen apparatus includes a frame, a panel coupleable to the frame, a drum, and a belt tensioner. An upper portion of the frame may have a mounting bracket that receives a motor/gear box. The drum may include one or more screen panels that may be removably attachable. The belt tensioner may include a first bolt that receives a first bracket with a belt guide roller. The belt tensioner may be configured to interact with the motor, the belt, and the drum. The belt tensioner may increase or decrease the tension of the belt that wraps around the drum.

Described are a washing machine and a control method for the washing machine. The washing machine includes: a water container; a filtering device, being configured to connect to the water container and to receive water in the water container for filtering, and has a sewage outlet for discharging sewage to the outside; a suction device, being configured to perform a suction action, drives the sewage in the filtering device to be discharged through the sewage outlet under the action of a pressure difference; and a recovery device, being configured to collect the sewage discharged by the filtering device. The recovery device can collect the sewage discharged by the filtering device, and a pressure difference can be formed inside and outside the sewage outlet of the filtering device through the suction action of the suction device, providing a driving force for the sewage to be discharged from the filtering device.

A system and method for the separation of oil and water. Contaminated water is introduced into a settling and separating bowl through an inlet pipe. The contaminants float to the top and are recovered by a weir skimmer. The weir skimmer is fluidly connected to a recovered oil tank which receives the recovered oil. An oil separator filter belt is located in the separating bowl and separates the bowl into two segments: an upstream end on the side closest to the inlet and a downstream end on the opposite side of the inlet of the belt. The oil separator filter belt aggregates entrapped and entrained oil and other contaminants.
