UNI:GEM SEPTIC CONVERSION UNIT

The Uni:Gem Septic Conversion Unit is an efficient, economical solution for sites where a new or replacement sewage treatment plant is unfeasible.

Available for sites up to 40+ persons, the Uni:Gem is a septic conversion unit which uses aerobic extended aeration, combined with biomass actuation to treat effluent from existing septic tanks or sewage treatment plants.

Uni:Gem units are suitable for domestic, commercial and agricultural applications. Hundreds of units have been successfully installed on sites throughout the UK and Europe.

Operating principle

Effluent from the existing septic tank or sewage treatment plant is transferred to the Uni:Gem unit and enters the aeration chamber where it is treated to remove dissolved constituents. Here aerobic bacteria, supported by diffused air and mobile media, ensures full treatment is achieved before the treated effluent (and ‘sloughed off’ bacteria) flows to a final settlement chamber prior to discharge via Polylok filter.
