The Detritor grit removal process (now known as J+A Crossflow™) was installed to significantly prolong the life of mechanical equipment at Severn Trent Water’s Minworth Sewage Treatment Works in Birmingham.

Removing several large skips of abrasive, heavy and insoluble grit every week, the four Detritor systems will help extend the life of all machinery to significantly decrease operational and maintenance costs.

Part of Severn Trent Water’s upgrade to improve process performance of the 1 billion litre per day plant, the 13m diameter Detritor units were chosen for their robustness and capability to handle the high flows at Minworth, the second largest sewage treatment works in the UK.

Richard Thomson, BNM Alliance M&E Project Manager, commented: “The Detritor technology stops grit from damaging vital equipment and processes, reducing front-line maintenance requirements”.

He added: “It was installed with exemplary health and safety standards, as well as timely delivery. Overall, it has been an outstanding engineering achievement based on robust and well-proven designs”.

A bridge-mounted grit removal system, the J+A Crossflow™ Detritor units and reciprocating rake classifiers are designed for simplicity, reliability and maintenance-free operation.
