Abrégé

An electrolytic cell comprising an electrolysis vessel for receiving a liquid electrolyte that fills the vessel to a predetermined level, electrodes for passing an electric current through the electrolyte, a vent for allowing gases produced by the electrolytic process to leave the vessel and an air inlet means located substantially adjacent to the predetermined level for directing air into the vessel at a predetermined rate.

Abrégé

A water filtration apparatus has at least one tank in fluid communication with a conduit through at least one aperture in a wall. Each tank uses filter blocks to support the filter medium and to direct the filtered water to the conduit via the aperture. An end plate for the filter block is provided, the end plate being adapted to seal against a free end of the filter block. The end plate also provides apertures for fluid flow into and out of the filter block, and a device for receiving a sealant to provide a seal between the end plate and the wall. The end plate improves the installation of the apparatus, and the sealant improves the reliability of the seal round the apertures, which in turn improves the efficiency of a backwash operation used to clean the filter medium.
