The central element (20) has one or multiple positioning elements (22, 24) which interact with counter positioning elements (116, 118) of an upper housing part (114) to fix the central element in the upper housing part (114) in a defined angular position. The central element (20) has at least one electrical connector element (32) on the element, electrically contacting at least one electrical connector element (120) on the housing.

The sludge dehydrator equipment is a machine that permits to remove low turbidity water from sludge or watery pastes of industrial or mining origin, with the following objectives: To optimize ore recovery processes such as flotation by means of an increase of the sludge density; To thicken sludge or watery pastes for optimizing the filtering and drying processes, as well as to dispose of mining tailings; To concentrate and dispose of solids in suspension and to recover and recycle clean or clarified water.

The sludge dehydrator equipment has been designed on the basis of a rectangular tank provided with the necessary infrastructure for containing inside a series of suction plates being connected to a vacuum system, through which the process of solid-liquid separation is carried out and, on the other hand, to contain the cleaning mechanism-the cleaning car-with its motor system made up by pneumatic or hydraulic components required to clean suction plates the filtering medium and to keep them permanently operative.

In accordance with the sludge dehydrator feeding and the design of the lower or bottom cone of the rectangular tank will benefit to be derived from the industrial and mining operation.

An icemaker appliance includes an ice maker positioned within a cabinet. A circulation conduit extends from a sump to the ice maker. A pump is connected to the circulation conduit such that the pump is operable to flow liquid water from the sump to the ice maker through the circulation conduit. A deionization filter assembly is coupled to the circulation conduit. A sensor is operable to measure a total dissolved solids value of the liquid water flowing through the circulation conduit.

A method including the steps of providing fluid through an inlet into a vessel at atmospheric pressure. The method further includes passing the fluid through a filtration unit utilizing a downstream pump, the filtration unit creating a flux of less than or equal to about 0.05 gallons per minute per square foot (GPM/ft.sup.2), and moving the fluid processed by the filtration unit through an outlet of the vessel.

A greywater recovery and reuse system is shown, including a body for collecting, conditioning and discharging greywater. The body has an inlet connection to a source of greywater; a filter for filtering the greywater; a tank for receiving the filtered greywater; a disinfector for disinfecting the filtered greywater; a pump for discharging the conditioned greywater from said tank to a toilet that needs flushing water; a discharge connection to a sanitary sewer system; a fresh water connection and a control system for controlling the operation of the greywater recovery and reuse system. The system includes a controller for operating the system and dealing with certain alarm and status conditions. Methods of operating the system are also comprehended.

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.
