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. With enhanced effluent quality available where consent to discharge dictates.
• 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.

Gaia Sege© Process design software for Ultra:Polylok sewage treatment plants

Developed by Marsh Industries, the unique Gaia Sege process design software uses core information to accurately calculate and tailor key variables, ensuring total optimisation for individual applications.

These precise calculations provide assurance to consultants, engineers, specifiers and contractors that the system is specifically designed to meet the appropriate standards of regulatory bodies.

For Ultra:Polylok sewage treatment plants, the programme employs core process equations to precisely calculate and modify critical variables, ensuring total processing optimisation for Biological Oxygen Demand (BOD), Total Suspended Solids (TSS) and Ammonia (NH4) reduction and removal.

Gaia Sege software also uses ‘British Water Flows & Loads’ data to calculate initial flows and loadings whilst also calculating peak flows and levels.

The programme can also calculate accurate sludge generation and storage on a daily basis, dependent upon final effluent standards required, ensuring the optimisation of primary chambers, individual clarifiers, diffused oxygen feed and final settlement chamber.

Size Options

Ultra:Polylok Sewage Treatment Plants are available in 1.9m, 2.5m and 3m diameters. To allow for site footprint and groundwork challenges.
