The Franklin Wastewater Treatment Plant utilizes a Two (2) Meter Belt Filter Press to dewater the sludge (bio-solids) before sending to the landfill. The bio-solids are a combination of solids produced during the biological reduction of organics and some inorganic material that cannot be broken down.
It is very important that the amount of solids in the treatment portion of the plant remain consistent. Too much or too little solids would be very harmful to our operation. Control of the bio-solids is the key to good treatment.
The contract for disposing of this waste is awarded through the bidding process every two years.
