By removing liquids from a variety of collected wastes, busy pumping professionals can save on labor, disposal and transportation costs
AQUA-Zyme Disposal Systems Inc.
The 30-cubic-yard dewa-tering unit from AQUA-Zyme Disposal Systems Inc. processes approximately 22,000 gallons of septic, municipal sludge and/or trap grease at 1 1/2-percent solids in 24 hours. Approximately 80 percent of the waste will drain off as effluent and can be routed to a wastewater treatment plant, land-applied or used in composting. The remaining dewatered sludge cake is 18 to 20 percent solids and acceptable at most landfills. The dewatering unit can be transported by a standard roll-off truck, hauled to the landfill or compost site. After a quick rinse, the unit is ready to process the next load. The unit works equally well on trap grease, septic and municipal sludge. Trap grease, however, has a remarkable odor and naturally low pH. By mixing the grease with other wastes, odors decrease and pH increases, eliminating the need to add lime. 979/245-5656; www.aqua-zyme.com.
Belt filter presses from Bright Technologies range from 0.8 (2.62 feet) to 3.2 meters (10.5 feet) in size and feature stainless steel construction, inclined gravity zone for efficient separation of liquids and solids, and radius wedge zone that automatically applies gentle pressure for optimum sludge conditioning.
