SHARON (Stable High activity Ammonia Removal Over Nitrite)
SHARON
The SHARON Process was developed by Grontmij in the 1990s in collaboration with Delft University of Technology and the Dutch water industry in an effort to reduce pollution to Dutch watercourses.
Total removal of ammonia
SHARON is used for the treatment of return liquors from wastewater treatment plants. Specifically it is used for the total removal of nitrogen components through nitrification/denitrification from wastewater flow streams containing high concentrations of ammonia.
Following the success of our initial research, it was selected as the method to be used at six large purpose-built plants, some of which have now used the process for 10 years.
The success of SHARON
The SHARON process is successful because it is a highly efficient and cost effective way of removing high strength ammonia from wastewaters arising from sludge treatment processes, thereby reducing the load to main treatment works.
SHARON is also a key step forward in sustainable water purification processes as it brings a 20% reduction in carbon dioxide emissions, a 40% saving on carbon and an impressive 25% saving in energy requirements when compared with conventional methods.
