Elimination of odours from DAF sludge holding tank.

Background

A Southern Ontario dairy plant uses a DAF to clean the wastewater of contaminants.  The sludge is scraped from the back of the DAF into a hopper which is then pumped to a holding tank.  The tank was then emptied once per week. 

The tank is vented at the top and as the sludge was pumped into the tank the displaced air would be forced out the top.  The resulting odours from the sludge caused complaints from neighbours and fear of product contamination especially during the summer months.  

The treatment process was a continual feed of diluted BCL-4000 and a daily addition of BCP-80 to the sludge prior to the tank.
