Marsh Ultra Polylok sewage treatment systems provide advanced biological treatment to off-mains wastewater. The units are designed to BSEN12255 and are ideally suited for larger residential, commercial, industrial and leisure sites serving 55-500+ people.

Proven reliability of the simple but effective Submerged Aeration Filtration (SAF-MBBR) system offers both operating and financial benefits when compared to more complex alternatives that require frequent servicing and maintenance to sustain performance.

Ultra-Polylok Benefits

  • Heavy duty shell as standard to enable installation in all ground conditions
  • Easily accessible low energy compressor(s) for minimal running, maintenance and servicing costs. Integral alarm detects low pressure in air line
  • High specification bio-media (310m3 per m2) and membrane diffusers ensure even circulation to eliminate 'dead spots'
  • Internal recirculation (from final to primary chamber) continues treatment process to provide higher effluent quality whilst balancing flow over 24 hour period or periods of intermittent use
  • Unique ‘keying-in’ lip to assist anchoring into granular or concrete surround
  • All plants fitted with the patented Polylok tertiary filter to reduce suspended solids in the final effluent by a further 35%, whilst also reducing residual BOD and Ammonia levels
