The wastewater plant will treat the wastewater for 250,000 people and will have the capacity to treat 95 million litres a day.

Siemens is supplying three chain and scraper systems for the removal of fats, oils, grit and grease from the wastewater treatment process.

The company 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, while also removing grease and other non-settling debris from the top of the tank via a scum tube arrangement.

After the removal of sludge, fats, oils, grease and grit the wastewater goes to the biological treatment phase.

Siemens says the technology gives energy savings through its ability to provide a low powered drive for continual operation, a non-metallic chain that does not corrode, and extended supporting warranties. Alison Brown
