Patent attributes
An apparatus includes integrated ultra-filtration and clarification, and an optional electrocoagulation capability. The apparatus comprises an outer tank, an inner casing, and a plurality of ultra-filtration filters contained within the inner casing. Clarification of liquid occurs in the gap between the casing and tank. Solid matter settles, and aggregates in the bottom portion of the tank. The accumulated solid material acts as a secondary filter by pre-filtering the liquid prior to contact with the ultra-filtration filters. Clarified liquid is retained in a chamber of the casing, and the clarified liquid is drawn through the ultra-filtration filters as initiated by a source of vacuum communicating with the ultra-filtration filters. Optionally, and upstream electrocoagulation unit and a downstream reverse osmosis unit are provided. Alternatively, the electrocoagulation function is provided by a plurality of reaction plates mounted to the interior sidewall of the tank.
