A NEW ODOUR CONTROL UNIT which aims to significantly help reduce odours from the waste water treatment works at Saltend, is now up and running says Yorkshire Water in a news release issued today.
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 and costing £3.5 million, 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, comments: “After months of hard work, we’re pleased to say we’re now in a position where we have this huge state-of-the-art unit up and running, just as we had scheduled.
“We know that for some years the local community has put up with intermittent odours from the site and this is clearly unacceptable. And whilst there is always likely to be some odour owing to the operational nature of the site, we’re confident that with this unit, which is the biggest in the region, will help to significantly reduce odours, ensuring they remain 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.
The company also continues to engage closely with the surrounding communities of Hedon and Paul, as well as East Riding of Yorkshire Council to ensure everyone is kept up-to-speed around the work and the progress that’s being made.
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.
