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;
