Description | 1. Currently the New Design Water Treatment Plant dewaters residuals from its treatment process of Potomac River water in the form of pressed residual “cake” utilizing a belt filter press. Two primary coagulants are used at the plant. Ferric Chloride is used primarily in the summer months otherwise Polyaluminum Chloride is used. It is estimated that the Water Treatment Plant will generate approximately thirty one hundred (3,100) tons of pressed sludge per year. Percent solids average 22.9% 2. The press is operated at various times on a seven-day per week basis as needed. The County averages two trailer loads per week. Trailers are backed in under the loading chute where dewatered residuals drop from a belt conveyor. Operators move the truck as needed to even the load. 3. There is no on-site container weighing equipment. The Contractor must utilize the scales located at the Ballenger McKinney Waste Water Treatment Plant, located at 7400 Marcies Choice Lane, Frederick, Maryland, to weigh trucks coming in empty and leaving full to determine the load weights for volumes hauled and for billing purposes. Pickup schedules shall be by mutual agreement. 4. Under this contract, the Contractor will provide empty trailers to be loaded by NDWTP staff |
