Complete lifecycle expertise
Through cross border collaboration, Sweco offers alternative solutions utilising European innovation including the energy efficient and low chemical consuming DEMON® and SHARON® liquor treatment technologies and InDENSE® that increases process throughput and performance. Sweco hold the European Licence for the following sludge related technologies:
SHARON® (Single reactor system for High activity Ammonium Removal Over Nitrite) is a sewage treatment process used for the removal of ammonia and organic nitrogen components from wastewater flow streams. The process results in stable nitrite formation, rather than complete oxidation to nitrate.
DEMON® is a continuous or SBR de-ammonification process that partly converts ammonia to nitrate and then converts the remaining ammonia and nitrate into nitrogen gas. The process uses only 40% of energy compared to conventional biological treatment systems and does not require an external carbon source.
InDENSE® that can be integrated into any existing plant, increases process throughput and performance through the selection of dense sludge aggregates with improved settling rates and the promotion of enhanced biological phosphorus removal.
We constantly push boundaries for sludge cracking, seeking alternative processes to incineration and maximising biogas production. With our expertise, we have delivered several biomethane upgrade plants for gas to grid solutions. In addition, we also advise European Water Boards and UK water utilities on bio-resource recovery technologies and we have advised on phosphorus and cellulose recovery schemes. We view carbon dioxide gas, bioplastics and alginate as future revenue generating opportunities.
