Dewatering system keeps grease from entering treatment plant

Dewatering system keeps grease from entering treatment plant

Problem: Grease from the collection system and waste haulers was entering the Jackson Energy Authority wastewater treatment plant in Tennessee, causing high levels of fats, oil and grease, BOD and TSS. It also was clogging lines and interfering with normal biological activity at the plant.

Solution: Rather than jetting the lines, the plant chose to install a grease dewatering station capable of handling 10,000 to 15,000 gpd, purchasing two Sludge Mate boxes from Flo Trend Systems to dewater the grease trap waste and return clear water to the intake of the plant.

Result: Dewatering is under the control of plant operator Tony Fitts. Grease haulers have a place to dump waste. The plant is able to set limits of less than 100 mL of FOG and less than 450 mL of BOD and TSS. Excess grease no longer enters the plant. To recover the cost of operation and fund repairs and upgrades when needed, the plant charges a per-gallon dumping fee. 800/762-9893;

Dosing pump system keeps lines free of grease

Problem: In July 2004, a customer called Speedy Clean Drain and Sewer for a thorough cleaning of a 50-gallon indoor grease trap that was backing up every five weeks.

Solution: Speedy Clean installed a Trap-Cleer dosing pump injection system into the mainline under the sink feeding into the grease trap. Two ounces of Liquid Trap-Cleer from Lenzyme was dosed each evening.

Result: In August, the trap was opened and inspected. The lines were clear and the trap was functioning as designed. In October, there was a 4-inch layer of grease at the bottom of the trap. The remainder of the system was operating as designed. After eight months, the trap required pumping. A second test showed the system was able to perform for eight months before requiring cleaning. A four-month maintenance program was established. After eight years, the system continues to work as designed. 800/223-3083;

Grease trap treatment ends backups, odors in restaurant

Problem: A large seafood restaurant had been troubled by backups and odors twice a month for several years despite frequent manual cleaning of the grease trap and drain lines. The wastewater system from the kitchen was served by a single in-floor grease trap. A series of sinks and floor drains were in place. Length of the mainline was 75 feet.

Solution: RoeTech Grease Trap Treatment from Roebic Laboratories was applied through two sinks upstream of the grease trap at the rate of 8 ounces per sink per day. The treatment was used for the first 30 days and applied through each floor drain at the rate of 8 ounces per drain per day.

Result: Odors were far less noticeable within the first week and disappeared completely after two weeks. There were no more backups and the foam from food processing ceased to be a problem in the floor drains. The system remains problem-free. Maintenance levels of grease trap treatment are at 85 ounces per week applied through two sinks and the four floor drains upstream of the grease trap. The trap has been opened only once for inspection and has not required manual cleaning since treatment began. 203/795-1283;

Lightweight grease interceptor an easy choice for assisted living center

Problem: In May 2012, Norton Sewer Service was called to replace a corroded steel grease interceptor at an assisted living facility in Chicago. The 1,300-pound steel unit required a special hoist for excavation. After it was removed from the pit, the steel was cut into eight pieces to fit through the service door.

Solution: The lightweight, high-density poly-ethylene (HDPE) Great Basin grease interceptor Model GB-75 from Schier Products replaced the steel unit. A built-in cover adapter was used to adjust the cover to finished grade without the need for an additional riser.

Result: The project took three contractors a combined 48 hours of work to complete. The new interceptor has a lifetime warranty. 800/827-7119;
