Thickening Reactor Aids in Grease Trap Waste Disposal

The thickening reactor from NewTech Inc. removes 90 percent of liquids from grease-trap waste, leaving a thicker, lighter-weight product that results in decreased waste-disposal and transportation costs for contractors.

In addition, the computer-controlled system is fully contained, which controls the odors normally associated with dewatering. It also is self-cleaning, which makes for less labor-intensive operation. “It’s easy to use and optimizes disposal,” says Robert Dimmick, president and owner of New Tech. “It’s a huge labor saver.”

The unit operates like a dewatering system. Grease-trap waste is pumped from a vacuum truck into a receiving tank, then processed through a dosing plant, where a polymer is injected. Then the waste is pumped into the stainless-steel thickening reactor tank, where solids and liquids are separated with carbon filters.

After allotting time for further liquid drainage to reach the desired thickness, the waste is pumped into a truck for transportation to a waste-disposal plant, methane digester or some other kind of facility, Dimmick says.

“Depending on the volume of waste, you can use one unit, which can process up to 60,000 gallons of waste in a 24-hour period,” he says. “Or you could use up to four units in a series, which would allow you to comfortably run 24 hours a day without shutting off the system, and process about 180,000 gallons of waste a day.

“The process removes 90 percent of the water and leaves a thick, concentrated material,” he adds. “Some contractors take that thickened material to methane digesters, where it creates methane gas that’s burned in generators. Or they can take the thickened waste to a waste-disposal site or composting facility.”

Computerized controls display information such as the waste levels in receiving tanks, whether the receiving pumps are on or off, levels in the thickening reactors, and the level of outgo flow. The system automatically shuts down when tanks are full or empty, and a camera system allows operators to see inside the tank.

The thickening reactor tanks can’t operate without a dosing plant and receiving tanks. A dosing plant, two receiving tanks and four thickening reactor tanks require approximately 1,000 square feet of floor space, Dimmick says. 800/210-2361; www.dewater91.com, Expo booths 4022, 4023.
