Marsh Ensign 16 Standard Sewage Treatment Plant

Marsh Ensign 16 Standard sewage treatment plant – 16 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 16 inhabitants, the Marsh Ensign:Standard 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:Standard?

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.
• Low-energy 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.
• 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’.
• Nylon 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.
• Impermeable lid
  Regular 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.
