BioCord™ pilot system proves mettle for cold-weather ammonia removal

Pulp and Paper | DATE POSTED: September 13, 2021

Onsite wastewater lagoons at a petrochemical manufacturing plant in Western Canada were experiencing difficulty in meeting the ammonia discharge limit during cold-weather conditions. The three-cell lagoon system provides pretreatment of the facility’s sanitary and process wastewater before the effluent is released to the municipal sewer. But during the winter months, the system struggles to achieve the discharge limit set by the city.

Learn how our simple, low-energy BioCord pilot system demonstrated 97% ammonia removal under some tough conditions.

Stora Enso paper pulp mill uses a 2,000,000 gallon tank to hold its wastewater to allow for the settling out of alum solids. Annually this take needed to be drained. With an expected 60,000-80,000 pounds of solids in the tank, Geotube® technology was used to dewater this tank. A high success rate was achieved with over 99% of total solids captured.
