Description
The District of Salmon Arm will conduct a three-month field test to recover phosphorus from its wastewater treatment plant. Phosphorus accumulating in equipment and piping causes operational problems as well as the growth of algae in Shuswap Lake. The field test will involve the recovery of phosphorus using a crystallizer developed by the University of British Columbia. The District of Salmon Arm will benefit from a succesful field test through less discharge of nitrates and phosphates into the environment, increased efficiency in the treatment plant, and the development of a potential new source of income through the sale of recovered phoshate crystals, a slow release salt, as a fertilizer. As well, the field test will gauge the effectiveness of the new technology and its applicability to other wastewater treatment facilities, with a particular emphasis on scaling such a crystallizer to the size of the treatment facility.
