Winter Ground Conditions - Sewage Treatment Plants

Winter Ground Conditions - Sewage Treatment Plants

In winter it can often be challenging to carry out the ground work necessary to install a sewage treatment plant.  With this activity often being at the formative stage of a project, it is important not to introduce delays to the project plan.   Marsh Industries have the ideal solution - the Shallow Ensign.  With a maximum depth of 1.6m, this treatment plant enables an easier and safer installation when contending with high water table, poor ground conditions or hard rock.

Marsh Ensign

The Marsh Ensign is widely regarded as one of the most efficient, reliable and economical sewage treatment plants on the market.  This shallow option enables installation to continue in the winter months or when up against challenging weather or ground.

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.

Why choose the Marsh Ensign?

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.

Features and Benefits

Inlet with ‘Forsheda seal’: Forsheda seal provides flexibility in the joint for easier installation.

Optional risers to increase invert depth are available.

Primary settlement chamber.

Aeration chamber.

Advanced compressor with alarm (Ensign:Ultra units only): Near silent compressor ensures minimal running, maintenance and servicing costs. Integral alarm detects low pressure in air line. (Regular Low-energy compressor on Ensign:Standard models).

Compressor housing – internal or external options available: The compressor can be housed internally or externally with no difference in cost.

External recommended to increase compressor life, and supplied as standard on 4PE, shallow and pumped outlet versions.

RCD/Electrical connection (Ensign:Ultra units only): The RCD box provides easier installation and proveds a higher degree of safety. (Regular plug/socket connection on Ensign:Standard models).

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 recycled bio-media (310m3 per m2) and membrane diffusers ensure even circulation to eliminate ‘dead spots’. The bio-media is contained by a stainless steel securing mesh to ensure no migration during handling or potential flooding.

Stainless steel mesh: Retains media in aeration chamber during transportation and handling, and in the event of flooding.

Final settlement chamber.

32 mm 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 (Ensign:Ultra units only): The Polylok tertiary filter reduces suspended solids and BOD by a further 40% helping to extend drainage field life.

Outlet with ‘Forsheda seal’: Forsheda seal provides flexibility in the joint for easier installation.

Optional pumped outlets are available.

Impermeable lid: Heavy duty lid/frame improves strength and durability whilst blending into the surrounding environment. (Regular lid on Ensign:Standard models).

Integral lifting eyes: For safe and secure on-site handling.

Stabilizing feet: Stabilizing 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.

CE marked.
