Marsh Ensign sewage treatment plants are considered one of the most efficient, reliable and economical solutions to off-mains waste water processing.

The Ensign:Ultra models have several features over standard Marsh Ensign sewage treatment plants:

  • Advanced compressor with alarm; near silent operation ensures minimal running, maintenance and servicing costs with low air pressure indicator
  • Dedicated RCD electrical connection (standard Ensign models have a standard plug/socket)
  • Unique Polylok filter reduces suspended solids and BOD by a further 40% helping to extend drainage field life
  • Heavy duty lid/frame improves strength and durability whilst blending into the surrounding environment

Tanks consist of three chambers; the first a primary settlement chamber where anaerobic digestion produces clarified water which filters to a second aeration chamber where, supported by diffused air and bio-media, bacteria treats the effluent. The third chamber is a settlement chamber where effluent is discharged into the drainage field or local watercourse.

Pumped versions and external cabinets available.

  • Tested to BS EN 12566:3 and CE-marked
  • Three chamber system correctly sized for separation and retention of solids improves final effluent quality
  • Low energy compressors ensure minimal running, maintenance and servicing costs
  • High specification bio-media (310m3 per m2 ) and membrane diffusers ensure even circulation to eliminate 'dead spots'
  • Integral lifting eyes for improved on-site handling
  • Unique ‘keying-in’ lip to assist anchoring into granular or concrete surround
  • Simple maintenance with easy desludging
