Marsh Ultra Polylok 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[...]
Designed and manufactured in accordance with BS4994/ BSEN976, the Marsh range of silage tanks provides environmentally safe storage of silage effluent. Available in capacities up to 100,000 litres in Ø2.5m and Ø3m diameters, the tanks are manufactured using GRP (virgin unfilled resin[...]
Degrilleur™ trash barrier
When non dissolvable objects are flushed into the sewer and then into a sewage treatment plant or pump station downstream, it can lead to blockage or worse - possible plant failure. To combat this Marsh Industries has developed the ‘Degrilleur’ – a[...]
Marsh GMS★ grease traps
Available in capacities from 2800 to 20,000 litres, Marsh Industries’ Grease Management System (GMS★) range of grease traps effectively prevents Fats, Oils and Grease (FOG) from entering the drainage network or sewage treatment plants. Testing and verification Marsh Industries has reassessed the[...]
Marsh Hydroil™ Bypass separators
A Bypass Oil Separator is used in a ‘low risk’ environment where there is no requirement to provide full treatment for the flow; for example a car park where the risk of a significant spillage is small. Designed and tested to BS[...]
Marsh Hydroil™ Full retention separators
A full retention oil separator is used where there may be a ‘high risk’ of a significant fuel spillage, such as vehicle workshops Designed and tested to BS EN858 parts 1&2, Marsh Hydroil full retention separators are manufactured from virgin unfilled resin[...]
Marsh Hydroil™ Forecourt separators
Designed and tested to BS EN858 parts 1&2, Marsh Hydroil forecourt oil separators are manufactured from virgin unfilled resin offering exceptional durability, impact resistance and are guaranteed to be watertight and of uniform thickness. These combined properties ensure that the full range[...]
Marsh Hydroil™ Wash-down separators
Available in capacities from 2000-20,000 litres, the Marsh washdown oil separator range safely removes silt and debris from vehicle wash-down facilities. These units are primarily used on car wash bays, pressure wash facilities or other cleaning facilities where the effluent must be[...]
Marsh Hydroil™ Silt traps
With a capacity of 1050 litres, a Marsh silt trap provides effective storage of silt and debris from vehicle wash-down facilities. Positioned ahead of an oil separator, the silt trap gathers and stores silt and sediment, and prevents it from entering the[...]
Oil separator alarm systems
An oil separator alarm monitors the level of liquid in oil separator units. An alarm signal is generated when there is an excessive level of oil, liquid or silt, or when the unit requires emptying. An oil separator alarm is required on[...]
Storm Dammer® stormwater attenuation and flood relief tanks
Available in capacities from 2800-110000 litres in multiple configurations with tank sizes ranging from Ø1.2m to Ø3m diameters, the Storm Dammer - stormwater attenuation tank - alleviates the risk of flooding and reduces pressure on drains/sewers by storing the excess flow of[...]
RainCell™ commercial rainwater harvesting systems
The Marsh Raincell is the simplest, most reliable and cost effective rainwater harvesting system on the market. With storage capacities to accommodate most roof sizes the Raincell system effectively stores and distributes clean recycled rainwater to properties allowing end-users to save on[...]
Project management for civil / commercial products
With extensive experience of managing the design and manufacture of civil, industrial and commercial products, such as pump stations, sewage treatment plants, attenuation tanks, rainwater harvesting systems and associated products, Marsh Industries’ Civils Team works closely with clients to ensure projects are delivered on time and on budget.
The company trains its team to recognised competency standards to address the growing management requirements from order placement through to delivery and installation.
All products are backed by Marsh Industries commercial and technical support.
Post installation and commissioning visits are available, together with service and maintenance contracts if required.
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.
Sewage treatment plants
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.
Gaia Sege utilises current building regulations to calculate precise storage chamber sizes. Pump systems are determined by using friction head loss calculations based on minimum self-cleansing velocities in order to specify the best possible pump(s) for the application.
Appropriate grease trap sizes are generated by accounting for the amount of grease and flow generated from the grease producing facility whilst providing adequate retention time befitting of these variables.
Storm Dammer water attenuation tanks
Marsh Industries’ rainfall storage sizing programme, Gaia Storm Dammer, can simulate the calculated flood storage required for any prolonged period within a set geographic area (ie, 1 in 5 year or 1 in 100 year rainfall).
