The invention comprises a control system for monitoring and operating an existing supply water pre-treatment system for supplying de-chlorinated water to dialysis purification systems. The invention includes a controller and an operator interface for programming and interacting with said control systems. The invention further includes an injection assembly having a flow turbine sensor, a reducing agent injector, and an ORP/pH sensor for monitoring and controlling ORP/pH levels of said supply water.

A method and system for water-priming carbon micropore filter media using negative pressure. The method includes placing dry filter elements in a polymer bag, applying a vacuum of no more than approximately 33 kPa above zero pressure, and heat-sealing the bag using a heat-set bar; submerging, by a consumer, the vacuum-sealed bag with its the filter elements in water; the filters in the vacuum sealed bag are at least partially submerged, puncturing the bag to form one or more small openings in the bag below the water line. Breeching the vacuum causes the water to flow through the openings into the bag and the filter(s) to equalize the pressure between the water and the previously vacuum environment of the plastic bag, causing the surrounding water to quickly flow into the micro-pores of the filter media, thereby priming the carbon filter for use in the gravity-fed water-purification system.

A device for separating the constituents of a fluid medium includes an element for separating the constituents, helping to define, upstream and/or downstream from the separation element, a closed chamber, to which at least one conduit is connected. The conduit includes at least one activatable sealing device, the activation of which is capable of at least partially closing and opening the conduit. The device also includes a controller for the activation of the sealing device, controlling the closing and opening, at least partially, of the conduit cyclically, at a frequency greater than 0.008 Hz.

An air purifier and a filter cleaner are provided. The filter cleaner is configured to be mounted in an air purifier. The filter cleaner comprises a motor, a cleaning member and a gear mechanism. The motor is configured to drive the gear mechanism to drive a radially outwards facing surface of a cylindrical air filter or a filter holding case past the cleaning member. The air purifier can comprise a polygonal casing and the cylindrical air filter can be located inside the polygonal casing so that a space is formed between the radially outwards facing surface of the cylindrical air filter and the inside corners of the polygonal casing. The filter cleaner can be located in the space between the corner and the filter.

A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.
