Marsh:Standard cost-effective sewage treatment systems provide biological treatment to off-mains wastewater on large residential, commercial, industrial and leisure sites ranging from 50-300+PE.
Proven reliability of the simple but effective Submerged Aeration Filtration (SAF-MBBR) system offers both operating and financial benefits when compared to more complex and expensive 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
Designed to BS12255, systems are available from 50-300+ PE in sizes ranging from Ø2.5-3m satisfying the demands of virtually all site conditions.
Class-leading effluent quality
Designed to British Water loadings (150litres per person, 60mg BOD litre and 8mg/litre Ammonia) ensures effluent discharge is well within national consent standards.
Cost-effective operation and maintenance
Systems have no internal moving parts and require minimal ongoing maintenance.
Heavy duty shell as standard
Structurally sound and built to last. Enables easy 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.
Lockable manhole covers
600mm lockable manhole covers provide significant strength and durability, and helps to reduce possible odours.
Health and Safety considerations
The Marsh:Standard can be fitted with many safety features including turret guards, failure alarms for compressor components and high level alarms.
Optional extras include carbon covers for odour control, turret guards for additional safety, polylok filters to further reduce suspended solids, high level alarms and telemetry for monitoring, and risers/pumped outlets for deeper installations.
Manufactured in the UK
All units are manufactured in our twin manufacturing plants at Kettering and Bridgwater. The tanks are constructed using GRP (virgin unfilled resin – no ‘fillers’ such as chalk) providing consistent wall thickness ensuring superior structural strength and durability.
