Veolia Water Technologies (Veolia) has secured a contract to upgrade the treatment process at Little Aston Wastewater Treatment Works (WwTW) to meet tighter ammonia discharge consent of 1 mg/l. Veolia’s Moving Bed Biofilm Reactor (MBBR) technology will provide a cost-effective alternative to replacing the existing trickle filters with a new activated sludge plant.
Severn Trent Water (STW) and Mott Macdonald Bentley, its Tier 1 delivery partner, were considering a number of options including replacing the existing trickle filters, which presented significant budget challenges. Early engagement with Veolia revealed that the existing trickle filters were in good condition with a suitable asset life, making MBBR technology an ideal tertiary treatment option, with significant CAPEX and OPEX benefits.
During the procurement process, process engineering and operations teams visited another STW site, Cudworth WwTW, to see the MBBR technology in action and were impressed by its ease of operation and process performance. Little Aston WwTW will be the seventh STW site to use Veolia’s MBBR technology, demonstrating the company’s expertise and credibility in the field, as it continues to pioneer and promote this wastewater treatment solution.
