Marsh Ultra Polylok commercial sewage treatment plants provide advanced biological treatment to off-mains wastewater on sites ranging from 50-500PE.
The units are ideally suited for large residential, commercial, industrial and leisure sites – particularly where onerous consent standards preclude the use of standard ‘off the shelf’ units.
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.
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 sewage treatment plants, the software uses established core process equations to accurately calculate and tailor key 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.
Marsh has launched a direct quotation website for the merchant and engineer/specifier; www.bespokesewagetreatmentplant.com. This user-friendly site caters to the design of sewage treatment plants for domestic, commercial and industrial sectors.
Configuration and components are shown for illustration purposes only
Bespoke design with optional tank sizes ranging from Ø1.9-3m satisfies the demands of site conditions. Each option is the same price.
Class-leading effluent quality
15:20:5mg/ltr (BOD:suspended solids:ammonia) effluent quality ensures discharge is well within national consent standards.
Heavy duty shell as standard
Structurally sound and built to last. Enables installation in all ground conditions.
High media surface area
High specification bio-media (310m3 per m2) and membrane diffusers provide even circulation to eliminate ‘dead spots’.
Low energy compressor(s)
Easily accessible low energy compressor for minimal running, maintenance and servicing costs. Integral alarm detects low pressure in air line.
Continues the treatment process to provide higher effluent quality whilst balancing flow over 24 hour period or periods of intermittent use.
Polylok tertiary filter
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.
600mm carbon cover provides significant strength and durability, and helps to reduce possible odours.
Optional extras include extensions for deep installations, pumped outlets for sites with adverse levels, sample chambers, Degrilleur trash barriers, phosphate reduction and UV treatment chambers.
