Waste Water – Sewage

Water Industry Odour Control Systems

ERG is a leading supplier of Odour Control Systems to the Water Industry

ERG is proud to be a framework Odour Control contractor for Thames Water, Southern Water and Scottish Water, and to count the majority of the UK’s Water Companies among our customers. We are also supplying the Odour Control for London’s Tideway Tunnel.

Cost-effective odour control systems

Based around our standard range of bio-trickling filters and carbon filters, we can offer a cost-effective solution for controlling the odour at sewage treatment plants. A typical configuration of a bio-trickling filter followed by a polishing carbon filter is effective for achieving a stack concentration of 1,000 ou_E/m³ or less from:

Pumping stations
Inlet works, screens, detritors and associated skips
Primary settlement and associated distribution chambers
Imported and exported sewage/sludge tanks and tanker loading/discharge
Primary, RAS, SAS, digested sludge tanks and dewatering equipment
THP processes
Cake storage

We also provide venturi scrubbers and chemical scrubbers for:

Sludge drying
Lime pasteurisation

Design Services

We have extensive design capabilities. In addition to straightforward design and build Odour projects, our clients also benefit from:

3D modelling of all packages – we model using Plant 3D and export as .dwg and Navisworks
BIM integration
Optioneering and FEED contracts

All design and build contracts include a complete set of design deliverables as standard.

Optioneering and FEED (Front End Engineering Design) contracts

There is frequently pressure to improve the odour impact of existing sewage treatment sites – new housing or commercial developments close to the site boundary, new processes requiring additional odour treatment, or older OCUs reaching the end of their service life.

ERG can help with defining the available options for upgrading existing assets and the preliminary engineering to allow formal project budgets to be set or released for implementation. We provide competitively priced design work carried out by our team of graduate and chartered engineers. In each case, the design output is tailored to meet the needs of the project – typical deliverables include:

Summary report identifying the available options for reusing/upgrading odour control assets versus providing new OCU(s)
Details of the technical and construction pros and cons of each option
Indicative CapEx and OpEx costings for major options
Preliminary engineering design for selected option – input to the formal project specification

Read about how this approach benefited Southern Water at Eastney and several other ERG clients who have recently implemented large odour control projects to improve their site’s existing odour control.
