Water companies open to the innovative principles of Advanced Grit ManagementTM (AGM) are expected to achieve significant operating and cost savings with a technology already successfully installed at some 200 operating plants in North America.
Hydro International is seeking water company partners to conduct pilot trials at wastewater plants in the UK, as well as to set up a full operating trial site. The trials will study the potential for AGM to establish new standards based on removing more, finer grit particles at the inlet works than has conventionally been accepted as standard. “The heavy cost of grit in wastewater treatment plant operation has long been accepted as an unavoidable burden by operators and asset managers alike,” says Keith Hutchings, Hydro International’s Group Product Manager. “Everyone knows that grit abrasion and accumulation are a burden of ongoing plant operation leading to heavy maintenance tasks and increased energy usage. Grit builds up in tanks, clogs basins and aeration tanks and compromises biological processes.
“The UK industry has accepted and grown to live with the burden of grit because of a compromise, a “one size fits all” industry standard for inlet works grit removal. With a new emphasis on TOTEX, we believe the time has come to challenge accepted norms. Grit sampling has never been conducted in the UK before and our sampling studies so far are providing strong evidence to support that view.”
The HeadCell® grit separation system has been developed and refined during more than 30 years of operation. The HeadCell® is combined with the rigorous AGM approach to achieve optimum grit removal for each wastewater treatment plant.
