Land applying food processing biosolids

Article Abstract:

A blanket of sludge, formed in the industrial wastewater pretreatment lagoon in Vancouver, WA, created a problem for the food processing industries of the city. Sludge was removed gradually from the lagoon by the use of a dredge and by continuous pumping. Experiments on the filter cake obtained from the sludge showed the presence of potassium, phosphorus and magnesium. The biosolids were formed from the food processing industries, rather than from human waste material.
