EnergyEco-friendly sewage plant processing solutions from Marsh Industries – designed for low impact, efficient off-mains drainage. Discover the benefits now.-efficient, economical and flexible process control for Ultra:Polylok sewage treatment plants.

Efficiency

Air blower speed/output is controlled using a variable speed ‘drive’ which supplies the precise amount of air required to enable the sewage treatment plant to function efficiently.

Optimisation of the air blower output results in improved running costs, meaning the end user can be assured they have the most economical solution for their wastewater system. This is a unique feature when it comes to overall energy-efficiency as most process control kiosks currently available within the industry have a one size fits all approach.

Flexibility

These next generation process control kiosks are built with flexibility in mind. Additional control options can be programmed into the ‘drive’ to regulate the volume of air delivered to the sewage treatment plant for different periods. This can be particularly beneficial for seasonal applications such as campsites, caravan parks, lodges or hotels where they may operate at peak capacity for short periods of the year. This functionality permits the volume of air to be increased or reduced, depending on the amount of people to be accommodated, thereby offering the end-user the ability to further reduce energy and running costs.

In addition, the process control kiosk allows for system expansion in the case of business/site growth (subject to design), thus eliminating the need to install extra tanks, pipework, air blowers, etc.

Noise reduction

We believe these kiosks to be the quietest on the market. They are fitted with a number of noise reduction measures as standard, making them ideal for caravan parks, campsites, etc, subject to kiosk placement/location. This may reduce the need for creating barriers or planting to restrict noise.

Further noise reduction measures can be added through the use of acoustic PUNF foam linings and various acoustic noise absorbing baffles. This not only reduces noise, but also enables the kiosk to be placed in a more convenient location, on sites where space is at a premium (the recommended distance from the sewage treatment plant should be 10m).

Specification/costs of noise reduction options, including measured decibel levels at a given distance from the kiosk, can be supplied on request.

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.

Gaia Sege© Process design software for Marsh:Standard 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 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.

Portable, compact, efficient sewage treatment solutions for small domestic properties, holiday homes, temporary accommodation and small commercial developments

The Portapura is the most compact and efficient sewage treatment plant we’ve ever made.

Designed for single domestic properties, holiday accommodation, site offices, site toilets, workshops, the Portapura is portable, can be installed above or below ground and treats domestic wastewater to a level that is 25 times better than the recommended EN standard.

Why choose Portapura?

It’s more efficient than other sewage treatment options… And more portable than all of them.

It’s a space-saving solution… Its compact design provides quick and easy installation with minimum visual impact on the surrounding landscape as well as simple and safe access for maintenance and cleaning.

It’s cost-effective… The cost of installing and running the Portapura is minimal when compared to larger, commercial systems.

It’s environmentally sensitive… CE approved to BS EN 12566 with an ammonia result that is 25 times better than the recommended EN standard means the Portapura is well within discharge consent requirements.

It’s designed specifically for temporary buildings and small domestic properties… Design objectives included performance, running costs, installation, transport and storage, making the Portapura the logical choice for sites where small wastewater treatment is required.

Phosphate and Ammonia reduction

Introducing the latest innovation in our extensive portfolio of domestic wastewater treatment products: the Marsh Gem-APS (Aerated Precipitation System)

The Gem-APS is designed to further reduce phosphates, ammonia and BOD from wastewater that has been previously treated in a domestic sewage treatment plant.

Note: Remote alert monitoring available for dosing. This can alert either Marsh Industries or the occupier when additional chemicals are required (including SMS/Telemetry options).

Positioned at the outlet end of any existing sewage treatment plant, the Gem-APS treats the discharged wastewater in a controlled process, involving small volumes of chemical dosing and aeration, in compliance with British Water and local environmental regulations, allowing the remaining effluent to be safely discharged to a river, ditch or drainage field.

Chemical dosing amounts are pre-configured based upon the expected flows and loads of the sewage treatment plant (Full scaleable detail available). The Gem-APS can also be regulated to reduce phosphate levels further.

Marsh offers commissioning and servicing of the Gem-APS, it is strongly advised to use this service when setting up the unit.

Phosphate: 0.9mg/L
Ammonia: 0.4mg/L
BOD: 2mg/L

The Gem-APS is a unique innovation for use on sites where phosphate discharge is a problem or where ammonia and BOD requirements are strict for planning consent.

Designed and manufactured in accordance with BS4994/ BSEN976, the Marsh range of cesspools provides environmentally safe storage of firewater, Elsan waste, silage and aviation fuel.

Available in capacities up to 100,000 litres in Ø2.5m and Ø3m diameters, the tanks are manufactured using GRP (virgin unfilled resin – no ‘fillers’ such as chalk) providing consistent wall thickness ensuring superior structural strength and durability. This also enables the tank to be significantly lighter for on-site handling/positioning and better suited to withstand greater hydrostatic pressures when in use.

The tanks are supplied with a chemically resistant gel-coat that protects the fibres in the laminates and provides excellent water and chemical resistance. This inherent integrity allows Marsh to offer an unrivalled 50 year design life, backed by a 25 year structural guarantee.

Guidance notes:

• Reference should be made to DEFRA guidance notes ‘The Control of Pollution (Silage, Slurry and Agricultural Fuel Oil) Regulations – UK’ and gov.uk guidance ‘Storing silage, slurry and agricultural fuel oil’
• Optional Bauer fittings are available

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 currently prescribed testing methods for grease traps and devised its own unique test rig and analysis at Loughborough University.

The rig, put to test for 12 months, addressed calls from the industry for clarity in testing procedures of grease trap technology. After completing trials, the new range of grease traps are the only products of their type that have been successfully tested using materials that match the FOG used in the food industry, as opposed to the traditional test method of using heating oils.

Applications
Typical applications where grease traps/separators may be required:

• Bakeries
• Canteens/kitchens
• Fast food restaurants
• Food processing factories
• Hotels
• Public houses
• Restaurants
• Social clubs

Marsh GMS★ Roundel

Compact grease management system

Marsh Industries’ GMS★ ‘Roundel’ – Ø1812 x 1m high – is shallow, compact and provides easy installation, particularly in urban areas or sites with arduous ground conditions and reduces the risk of undermining existing structures, pipelines or cable ducts.

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 bar screen which prevents any unsuitable materials from entering the system.

The unit has no moving parts and requires no electrics, is available in two capacities, 2000 and 12,000 litres, and is suitable for domestic, commercial and industrial installations.

The Degrilleur can also be used as a flow splitting chamber in multi-stream sewage treatment plants or as an upstream trash screen as part of stormwater attenuation systems.

Marsh:Marator oil separator – an innovative separator system that breaks the constraints of the current standards.

The Marator oil separator takes advantage of nanofiltration technology to produce discharge that is 50 times better than any current separator available on the market today; that is less than 0.1mg/ltr – the standard only requires less than 5mg/ltr for a ‘class 1 discharge’.

Testing was analysed for hydrocarbon content using infrared spectroscopy at GEOTAIX UMWELTTECHNOLOGIE GmbHA.

During the sampling period, five samples of 500ml were taken via the sampling point. The quality of discharge from the Marator exceeded the measureable level of the test equipment not to mention the current EN standard:
