Marsh:ENCO Sewage Treatment Plant 6-16PE

The Marsh Enco combines reliable performance with cost-effective operation, making it suitable for projects where efficiency and budget are key considerations.

Tested and approved to BSEN12566-3/A1:2009, all Enco units consistently treat wastewater within national consent standards, providing peace of mind for both installers and end users.

Available in sizes from 6 to 16PE, and with a wide range of ancillaries, the Enco range can support most site layouts, consent requirements, and budget needs, offering a flexible solution for a variety of projects.

Key Features

• Low-energy compressor - near silent compressor ensures minimal running, maintenance and servicing costs.

• 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.

• PVC pressure pipe/diffuser(s) - provides a protective conduit for the air diffuser line. Can be easily removed for maintenance and cleaning.

• Securing mesh - retains media in aeration chamber during transportation and handling, and in the event of flooding.

• Sludge return (32mm) - 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.

• Standard impermeable lid - improves strength and durability whilst blending into the surrounding environment.

• 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.

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

• Integral lifting eyes - for safe and secure handling onsite.

Operating Principle

In addition to anaerobic digestion taking place in the primary settlement chamber the Ensign:Ultra 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.
