Ensign sewage treatment plants
Marsh Ensign sewage treatment plants are widely regarded as one of the most efficient, reliable and economical systems on the market.
The Ensign:Standard is a robust unit with no internal moving parts meaning simple installation and commissioning and minimal long-term maintenance and cleaning.
Class leading performance
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.
Unrivalled choice
Ranging in size from 4 to 50 PE 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.
