  Trap grease separator reduces equipment fouling and odor complaints

Problem: Clean Earth Environmental, a contracting firm in Kalamazoo, Mich., pumps, hauls and processes septage and trap grease. They faced processing problems caused by trap grease fouling their equipment, requiring time-consuming shutdowns for cleaning. The firm also received odor complaints when processing grease. Additives reduced fouling, but increased processing and tipping costs, while grease disposal by land application was unappealing.

Solution: The RecoverE ESep trap grease separation system was an ideal solution. It accepts grease as pumped from the interceptor and separates it from water and most solids with an energy-efficient, two-stage, additive-free process. After separation, the water and solids are returned to the customer’s process. The brown grease is recovered as a pasteurized, low-water biosolid, which has intrinsic market value as a bioenergy or chemical resource. It operates as a closed system, simplifying odor management.

Result: The system reduced 30,000 gallons of as-pumped grease daily to about 500 to 1,500 gallons of solid, separated grease. By diverting grease truckloads, the firm reduced downtime on septage-handling equipment and increased operator efficiency. The system integrated seamlessly with the customer’s plant controls. Odor complaints from neighbors were reduced. They eliminated the need for additives, cutting processing and disposal costs by more than 75 percent. 269/370-3165; www.recovere.biz.

  Lightweight unit replaces outdated grease interceptor at assisted living facility

Problem: An assisted living facility in the Chicago area needed to replace a rusted steel grease interceptor. Due to the scope of the project and the physical size of the steel unit, the contractor, Norton Sewer Service, faced a big challenge in excavating and removing the old unit.

Solution: They decided to replace the steel unit with a Schier Products Great Basin model GB-75. First, the surrounding floor was jackhammered and a portable pump was used to drain the tank and surrounding excavation pit. Next, a portable hydraulic lift was used to remove the 1,300-pound, 150-gallon steel unit. The lightweight, polyethylene model was installed. The TeleGlide adjustable adapter allowed the contractor to bring the cover to grade without installing an additional riser. “I was amazed at the versatility of the design and the stress it took out of the equation,” says John Franck, President of Norton Sewer Service.

Result: The facility has saved thousands of dollars with the high-efficiency design, prolonging the pumpout cycle. A lifetime warranty against corrosion helps avoid future tear-outs and replacements. 800/827-7119; www.schierproducts.com.

  Dosing pump injection system stops frequent sewer clogs

Problem: The owner of Figaro’s Pizza, a restaurant in Howard, Wis., dealt with sewer backups into the business’s three-compartment sink every five weeks. The drainline would plug and the restaurant would close early so workers could clean up the mess, resulting in a loss of business and compromised sanitary conditions.

Solution: Speedy Clean Drain and Sewer completed a thorough cleaning of the 50-gallon indoor grease trap. They installed one Trap-Cleer dosing pump injection system from Lenzyme into the mainline located under the three-compartment sink and feeding into the grease trap. Liquid Trap-Cleer was dosed in at 2 ounces per evening. The solution is designed to keep the system flowing properly and consume much of the grease, extending the time between clean-outs and servicing.

Result: The system went from backing up every five weeks to operating normally, with only a small amount of grease buildup in the trap. The trap needed pumping after eight months of operation. Though the system performed eight months before it filled, it is recommended to clean the system when the grease level reaches one-third full. In this case, a cleaning every four months was established. 800/223-3083; www.lenzyme.com.
