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.
