Sludge Volume Reduction and Disposal Process.
Abstract
Evaluation of Pilot Waste Treatment Plant data and operating data from PBA Central Waste Treatment Plant disclosed several opportunities for improved chemical treatment that will produce a minimum volume of settleable sludge in the treated waste effluent. Better process control and optimization of chemicals usage are recommended. A pilot process for in-line sludge recovery, conditioning, and dewatering was designed, procured, and installed at Central Waste Treatment Plant. The demonstration runs resulted in dewatered sludged cake with an average solids content of 37 per cent. The MMT project resulted in selected of low-shear pumps for sludge handling; Lamella-type settling equipment; and low energy multi-roll sludge press dewatering equipment. Evaluation of sludge disposal options and regulatory requirements of State and Federal agencies has resulted in a funded MCA-86 Hazardous Landfill/Closure Project for on-post disposal of dewatered sludge and other Pine Bluff Arsenal hazardous or chemical solid wastes. Estimated total cost for sludge recovery, dewatering, and hazardous landfill disposal is Seventy Dollars per ton.
