£3.5m odour control unit for Hull Sewage Works

A new £3.5 million odour control unit which Yorkshire Water believes will significantly help to reduce odours from its Hull waste water treatment works in Hedon, is now up and running.

After three weeks of successful trials, engineering specialist Morgan Sindall have confirmed that it is operating as it should and given the go-ahead for the unit to 'go live'.

At twice the size of the current on-site facility, the new unit is the biggest in the region.

Operating alongside the existing facility, it will take air from the sludge processing part of the plant - typically the most odorous area - and treat it using Turkish pumice infused with natural 'good' bacteria in 10 large black tanks.

Tests carried out at the stack over the trial period have revealed that no hydrogen sulphide - the gas that gives off 'a rotten egg' like odour - has been emitted from the facility's 28 metre high chimney.

Richard Sears, community engagement manager at Yorkshire Water said that although there was always likely to be some odour owing to the operational nature of the site, the company was confident that the unit would help to significantly reduce odours and ensure that they remained within guideline levels.

The bespoke system has been designed by Odour Control Systems, for main contractor Morgan Sindall and uses tanks manufactured by Northern Plastics in Bradford.

In addition to the new unit, the company is closely monitoring the day-to-day processes involved in the treatment process, with industry experts and leading scientists working to ensure any odours are kept to a minimum.

Commissioned in 2000, Hull waste water treatment works is one of the biggest plants of its kind anywhere in Europe treating 40 million gallons of waste water everyday, including a complex mix of trade effluent.
