According to a press release, Severn Water has committed to an agreement with waste water firm Next Filtration to implement its Next FOG (fats, oils and greases) STOP technology into their water systems.

The technology is designed to reduce the build-up of FOG in sewers.

Also including evaluation of additional systems, the deal follows an 18-month trial of the technology. The release claims that during this period, the technology reduced maintenance costs and flooding associated with sewage blockages.

Described as a ‘safe’ and ‘environmentally benign’ technology, Next Filtration alleges that the FOG STOP system can also reduce aeration costs, the accumulation of biomass as well as control hydrogen sulphide (H2S).

“We’re looking forward to moving into the next phase of collaboration with Next Filtration. Sewer blockages and associated flooding are a huge problem for us and our customers - and we are excited about how using new and innovative products can help us mitigate challenges and provide a better customer service,” said deputy chief engineer at Severn Trent, Bob Stear.

“We will continue to remind our customers that fats, oils and greases should never be flushed down the sink or toilet - and until everyone disposes of these properly, we’ll be using this solution to help tackle the problem.”
