Suitable for large residential, commercial, industrial and leisure sites - particularly where onerous consent standards preclude the use of standard 'off the shelf' units.

Marsh Ultra Polylok sewage treatment systems provide advanced biological treatment to off-mains wastewater on sites ranging from 50-1000+ PE.

The 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.

Features and benefits:

• 20:30:20 mg/L effluent quality.
• Heavy duty shell as standard to enable installation in all ground conditions.
• High media surface area to provide even circulation and eliminate 'dead spots'.
• Eco-friendly process control for minimal running, maintenance and servicing costs
• Internal recirculation to provide higher effluent quality.
• Polylok tertiary filter to reduce suspended solids in the final effluent.
• Carbon covers provides strength and durability, and help to reduce possible odours.
