Common sewage treatment plants on the market often exceed 2.3m high. Shallow Ensign sewage treatment plants from 4-35PE are only 1.6m in height, meaning installation is not only possible*, but easier and safer too.
*Shallow Ensign’s are often favoured when hard rock site conditions mean deeper alternatives, involving costly and time-consuming excavation.
Shallow 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.
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 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.
End users, merchants and installers alike recommend the Ensign range due to its ease of installation, reliability, and cost-effective operation and maintenance. All backed by technical support from local contacts.
In addition to anaerobic digestion taking place in the primary settlement chamber  the Ensign unit allows the clarified water to pass into a second ‘aeration’ chamber  where it is treated to remove the 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 . The final effluent is then discharged to the drainage field or watercourse via a Polylok filter.
