A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

A multi-valve water treatment system (100) comprising a motor (3) having an output shaft, a driven shaft (2) fixed to the output shaft such that the driven shaft (2) is driven by the motor (3) when the motor (3) is activated, the driven shaft (2) having at least one cam (21A-21C) disposed at an axial position along the driven shaft (2), and a valve assembly (6) including, a valve actuator (61A-61C) urged into engagement with the driven shaft (2) at the axial position, such that the valve actuator (61A-61C) is moved axially upon engagement with the cam (21A-21C), a fluid flow housing (1) having a fluid outlet (411) and at least one fluid inlet (412A-412C) selectively sealingly engaged by the valve actuator (61A-61C) such that the fluid inlet (412A-412C) selectively allows flow from the fluid inlet (412A-412C) to the fluid outlet (411) depending on the position of the valve actuator (61A-61C), and a diaphragm (5) sealingly isolating the fluid inlet (412A-412C) and the fluid outlet (411) of the housing (1) from the valve actuator (61A-61C).

A water treatment system protects chlorine generator electrodes from miming dry. The system includes a water detection electrode (222) disposed above the chlorine generator electrode (223), and an outlet (12) at a height similar to the water detection electrode (222). If enough water is displaced from the housing (1) of the water treatment system by bubbles (4) generated by the energized chlorine generator, the water detection electrode (222) will cease to be bathed in water and will emit a signal indicative of this “dry” condition. The signal can be used to interrupt electrical power to the chlorine generator, thereby ensuring that the chlorine generator will not displace the water bathing it and therefore will not run dry.

A method and a control system for water used in a food processing system are provided. For example, the control system includes at least one sensor configured to collect a sensor signal from a produce handling device, a logic processor configured to receive the sensor signal collected by the at least one sensor and generate a control signal for controlling adding wash solution to the water used in the food processing system, and a human machine interface (HMI) configured to display information from the logic processor to a user.

Compositions, systems, and methods of using alkaline-producing Aluminate salts in the sludge collection and digestion steps of wastewater processing to reduce acidity and/or build alkalinity, reduce hydrogen sulfide release, and reduce phosphate in the effluent.

System and process for the treatment of water using a ferrate-based reduction-oxidation (redox) reactor, a clarifier, and a two-stage filtration system. Three treatment substrates can be used to treat water in the water treatment system and process, namely, a ferric compound(s), an acidic oxidant, and a flocculant-adsorbent.

A reactive toilet treatment packaged formulation and method for treatment of waste material resulting in a more stable, entombed treated waste product. The reactive toilet treatment comprises a foamable surfactant that is granular and sodium percarbonate. A multi-part formulation can be delivered in a multi-compartment vessel that cooperates with a self-contained non-contact agitating toilet. The reactive treatment formulation prevents odors, bacterial growth, and stabilizes waste to reduce spillage during disposal.

Described is a container, a cartridge, a kit and method for slow release of algaecide in swimming pools. The container comprises: a hollow housing comprising a top portion with an internal cavity defining a sub-hollow space within the housing; an open bottom portion for filling the housing with the algaecide; and a lid for closing the open bottom portion of the housing. The cartridge comprises a container having a top portion comprising an internal cavity defining a sub-hollow space within the housing, that sub-hollow space comprising a dissolving powderous compound. The cartridge further comprises a dissolving algaecide composition cast inside the housing and covering the dissolving powderous compound. Described also is a method for the slow release of algaecide, and kits comprising the cartridge. Slow release of algaecide during an extended period with the cartridge is helpful in the main maintenance of swimming pools, particularly during the wintering period.

A channel block for a liquid chemical dosing apparatus. The channel block has a process outlet; a chemical liquid inlet; an evacuation outlet; a calibration column outlet; channels provided within the channel block that connect at least the process outlet, the chemical liquid inlet, the evacuation outlet and the calibration column outlet; a pressure indicator mounted to the channel block to measure the pressure of the chemical liquid entering through the chemical liquid inlet; a additional regulation valve mounted to the channel block upstream of at least one of the process outlet and the calibration column outlet; a evacuation regulation valve mounted to the channel block upstream of the evacuation outlet; at least three control valves mounted to the block configured to control the chemical liquid passing through the channels.
