Press used to further dewater oily sludge

Problem: Action Environmental of Fort Wayne, Indiana, specializes in the treatment of wastewater from industrial cleaning, machinery maintenance and remediation. Ed Black, president of Action Environmental, was looking for a solution that would allow further dewatering of the oily sludge produced during their main treatment process. For years, the company has been hauling the sludge to a landfill.

Solution: The MD Press 202 from Trident Processes receives the material directly from the plant’s sludge holding tank. For thin, diluted sludge, a polymer can be applied with the unit’s optional floc tank and mixer. The system only requires 1 hp. Black reported that the Trident press “allowed us to seamlessly treat variable, mixed media sludge types.”

Result: The MD Press proved to be the right choice for Black’s plant operation. For every drum of solids, his team separates one to two drums of liquid for an estimated 50 to 65 percent weekly reduction in landfill loads hauled. The tested samples also passed the landfill’s paint filter test, which is an indication of more savings to come. 800/799-3740; www.tridentprocesses.com.


Grease digester solves odor issues at golf course

Problem: Foul odors were emitting from three combined sewer manhole units 25 feet away from the 18th green and 75 feet from the outside dining facility of a Detroit-area country club. The combined sewers had grease, food waste, sludge and human waste multiple feet thick. The area downstream had to be pumped regularly by the municipality. Offensive odors were also present inside the clubhouse.

Solution: The Eco-Drain System Company stepped in with a protocol designed to eliminate the problem using a BioForce Heavy Duty Grease Digester from Chempace Corporation. The sewers were dosed daily in addition to treatment inside the building.

Result: After 10 days, less water and less sludge was reported in the sewers. The odor was also dissipating. A visit 45 days later confirmed the solution was working. 800/423-5350; www.chempace.com.
