Siemens systems for Brighton wastewater plant
2 Jun 2011
Brighton, UK – Siemens Water Technologies is to supply three chain and scraper systems to Southern Water for the new wastewater treatment plant (WWTP) being built to serve the Brighton and Hove region of East Sussex.
The Envirex chain and scraper system, which will form part of the new wastewater works in Peacehaven, was installed in May 2011 and will become operational in 2012. The WWTP, noted Siemens, is the only new build plant of its kind in the AMP 5 cycle.
Once operational, the plant will serve 250,000 people and will have a capacity to treat 95 million litres per day. It is being built to ensure the safe collection, treatment and recycling of wastewater to the latest European standards currently carried out by Southern Water across the region.
Siemens is supplying three chain and scraper systems for the removal of fats, oils, grit and grease from the wastewater treatment process. Siemens will supply the complete design to Veolia Water Solutions & Technologies’ specification, mechanical installation, and commissioning of the system.
The Envirex chain and scraper system removes settled solids from the bottom of the collection tank, whilst also removing grease and other non-settling debris from the top of the tank via a scum tube arrangement.
This, claims Siemens, provides a comprehensive removal of sludge, fats, oils, grease and grit from the wastewater before it goes to the biological treatment phase. It also features an energy-saving low powered drive for the continual operation, and a corrosion-proof, non metallic chain.
