EVALUATING BENEFITS OF CLASS A BIOSOLIDS CAKE PRODUCTION.

A national survey of both small and large-scale wastewater treatment facilities shows varied approaches to reaching markets with superior methods that take the ''biosolids out of the biosolids."Increasingly, biosolids program managers are feeling pressure to go to Class A production. Reasons include: Class A biosolids are expected to be viewed as safer by the general public leading to greater acceptance of beneficial use of biosolids; Use of Class A material is not restricted and no site specific permits or plans are required, suggesting that more beneficial end use options are available, potentially at lower cost than traditional beneficial uses for Class B material.
