Belt press helps processing facility increase production

Problem: A Midwest liquid waste haulers processing facility was growing so quickly that it was running its dewatering processes 24 hour per day and barely keeping up. Its rotary fan press was slow and broke down frequently while processing the 2% to 6% solids grease trap waste. There was also limited space available for new equipment. Officials sought to replace the fan press with technology that could process 80,000 to 100,000 gallons in a 10- to 12-hour shift while also utilizing an existing 4-foot-wide belt press.

Solution: Bright Technologies, Division of Sebright Products, engineered a 5.5-foot-wide skid-mounted belt press and filtrate pumping system. The press operates at 170 to 255 gpm at 50% to 60% cake solids.

Result: The new press enabled the facility to make its daily production rate goal without needing to use the other press. The new unit provided higher throughput and cake solids than the facility had previously seen while being more forgiving of sludge variation. In addition, its operator controls are user-friendly. 800-253-0532;
