SHARON, safe nitrogen removal from waste water
Robust and cost effective
Developed by Grontmij, SHARON is a patented robust and cost effective system for the removal of nitrogen from wastewater.
The process is used for treatment of high strength ammonia liquors such as sludge dewatering liquors and the liquid fraction of pig manure.
When compared to traditional nitrification/de-nitrification the savings are:
- 25 % on energy, due to lower oxygen demand;
- 40 % on carbon source for denitrification;
- 30 % on sludge production.
Grontmij has more than a decade of full scale operational experience in developing and implementing the SHARON process in active plants. The Process is currently in operation in the Netherlands, United Kingdom, Sweden and New York (USA). SHARON plants are in preparation for Geneva (Switzerland) and Paris (France).
