Marsh Ensign 12 Ultra sewage treatment plant – 12 population
Marsh Ensign sewage treatment plants are widely regarded as one of the most efficient, reliable and economical systems on the market.
Designed to treat household wastewater for properties with up to 12 inhabitants, the Marsh Ensign:Ultra is widely regarded as one of the most efficient, reliable and economical sewage treatment plants on the market.
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.
- Optional risers to increase invert depth are available
- Optional pumped outlets are also available
Why choose the Marsh Ensign:Ultra?
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.
- Inlets and outlets with ‘Forsheda seal’
Forsheda seals provide flexibility in the joint for easier installation. - Advanced compressor with alarm
Near silent compressor ensures minimal running, maintenance and servicing costs. Integral alarm detects low pressure in air line. - Compressor housing – Internal or external options available
The compressor can be housed internally or externally with no difference in cost. External compressor is recommended to increase compressor life – this is supplied as standard on 4PE, shallow and pumped outlet models. - RCD/Electrical connection
The RCD box provides easier installation and provides a higher degree of safety. - Whisspurr acoustic vibration reduction unit
Fitted inline between the compressor and air diffuser, the Whisspurr significantly reduces noise and vibration generated from the pulsation of the diaphragm compressor whilst enabling a consistent, unrestricted flow to the air diffuser. - PVC pressure pipe/diffuser(s)
Provides a protective conduit for the air diffuser line. Can be easily removed for maintenance and cleaning. - Bio-media
High specification bio-media (310m3 per m2) and membrane diffusers ensure even circulation to eliminate ‘dead spots’. - Stainless steel mesh
Retains media in aeration chamber during transportation and handling, and in the event of flooding. - 32mm sludge return
Larger diameter sludge return prevents the possibility of blockages and improves system circulation. Provides higher effluent quality whilst balancing flow over a 24 hour period or periods of intermittent use. - Unique Polylok tertiary filter
The Polylok tertiary filter reduces suspended solids and BOD by a further 40% helping to extend drainage field life. - Impermeable lid
Heavy duty lid/frame improves strength and durability whilst blending into the surrounding environment. - Integral lifting eyes
For safe and secure on-site handling. - Stabilising feet
Stabilising feet prevents the tank from rolling and allows safe and steady transportation and installation. - Unique ‘keying-in’ lip
Assists anchoring into granular or concrete surrounds.
Operating Principle
The tank utilises a three-chamber design to produce its high-quality effluent. The first chamber is where primary settlement takes place and where anaerobic digestion produces clarified water. This water then filters into a second aeration chamber where, supported by diffused air and bio-media, bacteria treats the effluent to remove the dissolved constituents. The third chamber is where final settlement takes place before the effluent is discharged into a drainage field or local watercourse. The unique Polylok tertiary filter positioned within the outlet reduces suspended solids and BOD by a further 40% helping to extend drainage field life.

Great company to do business with. Keen prices, reliable delivery and exceptional after sales service. Just a shame more companies can’t manage to keep up.
