Title: Apparatus for water treatment
Inventor: ELLIS ANDERSON
IPC: C02F9/00
Filed: 1988-11-07
Granted: 1996-05-01
Abstract: An apparatus for purification and/or sterilization or disinfection of water which has a head (10) with water inlet (12) and outlet (14) openings and a housing (22) secured in water tight relation to said head in which there is a cylindrical filter (18), preferably of activated charcoal. Between the filter and the housing is an outer water channel (28) communicating with the water inlet so that water entering the apparatus is purified by passing through the filter to an inner channel (30) communicating with the water outlet. Water is sterilized or disinfected by an ultraviolet lamp (20) inside the filter over which water that has passed through it flows to the water outlet. The apparatus may be used in multiples which are connected in series or parallel to obtain a greater degree of filtration and disinfection than obtainable in a single unit.
