Large dewatering solution needed for North Carolina septic and grease trap pumper

Problem: Stanley Environmental Solutions offers septic and grease trap services in North Carolina, and has been doing onsite dewatering of the septic and grease sludge for many years. The company needed dewatering containers capable of processing 70,000 gallons per day.

Solution: The company installed several dewatering containers from Bakers Waste Equipment in its on-site dewatering system includes a number of Bakers Waste Equipment dewatering containers. “We have been able to keep our total suspended solids below 50 ppm with this dewatering solution,” said Jim Lanier of Stanley Environmental.

Result: “Our limits with the city are 250 ppm; then a surcharge is implemented. So these dewatering containers have proven to be very cost-effective for our onsite processing of septic and grease, meeting the paint filter test,” said Lanier. 800/221-4153; www.bwe-nc.com.

Screw press replaces dewatering system destroyed in fire

Problem: Tim Frank Septic Tank Cleaning Co. in northern Ohio began a dewatering operation in 1994. However, a fire in 2007 destroyed the company’s dewatering building and press.

Solution: Having hosted a National Association of Wastewater Technicians waste treatment symposium at their facility before the fire, Tim and Tom Frank saw various dewatering technologies in operation at their site. They decided to install a screw press from FKC Co. in the new dewatering facility.

Result: Currently the screw press dewaters a mixture of septage and sludge from small commercial treatment plants to a consistency of approximately 30 percent solids. The solids are disposed of in a landfill and/or land-applied. Filtrate from the screw press is treated in lagoons and man-made wetlands before being spray-irrigated onto farmland currently growing giant miscanthus, which will be used as a renewable fuel. 360/452-9472; www.fkcscrewpress.com.
