How to clear 50,000 cubic metres of sludge in six months

摘要

Two Aldec G2 decanter centrifuges from Alfa A Laval have helped Yorkshire Water avoid a potential environmental problem at its Esholt Sewage Treatment Works by clearing a backlog of 50,000 cubic metres of sludge in just six months. Covering no less than 340 acres and serving the Bradford area, Yorkshire Water's Esholt Sewage Treatment Works is the largest filter site of its kind in Europe. Its complex of mineral filters handles the sewage generated by a total equivalent population of 600,000 in West Yorkshire and produces a humus sludge that is treated, dewatered and then mixed with wood waste to produce a rich conditioned sludge which is then used for either agriculture or land remediation.
