Reliable approach for phosphorus removal

Newthorpe STW (2023)

North-west of Nottingham and separated by the River Erewash, two of Severn Trent’s sewage treatment works are situated within 2.5km of each other; part of the legacy of the times of the public statutory undertakers. Heanor Milnhay STW in Derbyshire has a dual-stream process, with part of the flows going through trickle filters and the […]

Southern Water WINEP (2023)

To ensure compliance with tighter Environment Agency permits for phosphorus removal, the number of phosphorus reduction schemes have quadrupled since AMP5 and is seen by some as one of the biggest challenges ever to face the water industry. The Water Industry National Environment Programme (WINEP) is a programme of actions that water companies are required […]

Hayfield & Barton WwTWs (2021)

In recent years, phosphorus discharge limits have been tightened to improve the surface water quality, particularly to address eutrophication issues. Before 2015, only a small number of sites in the UK had a total phosphorus (TP) permit as low as 1 mg/l under the Habitats Directive. Since then, TP permits have been continuously tightened in order to achieve […]

Ledbury & Brockhampton STWs (2021)

Both Ledbury and Brockhampton are medium sized works (c15,000 PE) serving the catchments of Ledbury and Cheltenham respectively. Each site was subject to a first-time phosphorus permit with Brockhampton receiving higher flow to full treatment and a tighter BOD permit, and Ledbury having significant growth projected in the catchment. Both sites both required new tertiary […]

Codsall STW (2019)

Severn Trent (ST) and Hafren Dyfrdwy (HD) have been challenged to meet a large number of new, tight phosphorus permits as a result of the Water Framework Directive (WFD). Historically, only Total-P levels down to 1 mg/l have been enforced by the Environment Agency, but in AMP6 and AMP7 a big step change in expectations […]

FilterClear® (2024)

Reliable approach for phosphorus removal

HYBACS® (2018)

Following decades of investment, the UK has a comprehensive sanitation system and a legacy of wastewater treatment plants. As environmental standards continue to tighten, many of these older assets require an upgrade to provide additional treatment capacity and to meet higher quality standards. The conventional approach for many years has been simple: build more tanks […]
