Colloide, working in partnership with Severn Trent and Galliford Try, was selected as a specialist sub-contractor to deliver an advanced chemical dosing system at the Albrighton Sewage Treatment Works (STW). This project, part of Severn Trent’s initiative to meet tighter regulatory standards for phosphorus removal, showcases Colloide’s expertise in water treatment and sustainable engineering solutions.

Phosphorus is a common pollutant in wastewater, and if released untreated into natural water bodies, it can contribute to eutrophication, causing excessive algae growth that disrupts aquatic ecosystems. Colloide’s chemical dosing solution at Albrighton STW helps mitigate this risk by removing phosphorus efficiently from the wastewater stream. The newly installed system uses a 10m³ Tank 2 Pump Ferric Sulphate dosing configuration, which introduces ferric sulphate into the treatment process to bind with phosphorus, forming a compound that can be separated from the water. This process not only ensures compliance with environmental regulations but also contributes to improved water quality in downstream ecosystems.

One of the key functions of this dosing system is to adjust the pH levels in the treated wastewater. By fine-tuning the pH, the dosing system optimises the effectiveness of the phosphorus removal process, enhancing the overall efficiency and reliability of the treatment works. This new installation at Albrighton STW demonstrates Colloide’s commitment to delivering sustainable, high-performance solutions tailored to complex environmental requirements.
