DOMESTIC SEWAGE TREATMENT PLANTS Marsh Ensign TM Sewage treatment plant The Marsh Ensign is widely regarded as one of the most efficient, reliable and economical sewage treatment plants on the market. Tested and approved to BSEN12566-3/A1:2009 all Ensign units provide treatment well within national consent requirements. Published test results of 11.5:19.2:8.4mg/ltr (BOD:suspended solids:ammonia), with influent concentrations on test higher than those chosen by most competitor plants, effectively equates to 97% pollutant removal. Ranging in size from 4 to 50PE in Ultra, Standard and Shallow versions of each, and with a wide range of ancillaries, almost all site, consent and budget requirements can be met by units from the range. Uni:Gem Septic tank conversion unit Marsh Industries’ latest innovation, the Uni:Gem , is a unique septic tank conversion unit which exceeds EN12566-3 / EN12566-6 standards and conforms with 2020 General Binding Rules (GBRs for septic tanks or small sewage treatment plants for domestic use). Positioned behind any existing septic tank the Uni:Gem treats the septic tank discharge to an effluent quality of BOD 12.25:TSS 16:Ammonia 14.845 mg/l (The UK Forward is less than BOD 20:TSS 30: Ammonia 20), meaning final effluent can be discharged safely to a river, ditch or watercourse. The Uni:Gem provides notable benefits for existing septic tank owners, particularly those who need to upgrade or replace their septic tanks before 1st January 2020.
