Water and wastewater solutions provider ACWA Services starts 2017 with three new design and build contracts for nitrate removal plants worth in excess of USD3.85 million, including a new solution for Cambridge Water at Fowlmere WTW. All plants will utilize ACWA's highly successful ion exchange Nitreat technology, already deployed at 27 water treatment works (WTW) in the North and East of the country to ensure drinking water quality in line with DWI quality targets, within Nitrate Vulnerable Zones (NVZ). For lead contractor Integrated Water Services (IWS) work is due to commence at Cambridge Water's Fowlmere WTW to the south of Cambridge in September. The new plant, which follows the completion of projects for Cambridge Water at Babraham, Euston and Fleam Dyke, is designed with sufficient capacity to treat a raw water flow of 5,400m3 per day from onsite boreholes, reducing nitrate levels of 79.6mg/l to produce a final blended water flow with nitrate levels at 43mg/l. For all three projects ACWA is responsible for process, mechanical, electrical and instrumentation works, through to commissioning. The solution at Fowlmere WTW will incorporate a single Nitreat skid complete with transfer pumps, self-backwashing micro strainer, a duplex water softener system, brine system for regeneration (with a single salt saturator located outside within a bunded area), waste tanks plus interconnecting pipework and valving along with a dedicated MCC control panel and associated cabling. IWS will also be responsible for civil works including the treatment building and work is expected to be completed in June 2018.
