The Problem
Wastewater containing grease represents a significant challenge for treatment at wastewater treatment plants. This type of wastewater traditionally has congealed in lines, upset activated sludge systems and digestors, and generally was considered to be non-compatible with any type of wastewater treatment facility. Restaurants, fast food establishments, food processors, hotels, institutions, etc., are required to have a grease trap that permits the grease to congeal and prevents the grease from being discharged into the sewer system. However, the congealed grease must periodically be removed from the traps for disposal.

The Solution
RGF developed a proprietary system which is compatible with existing wastewater treatment facilities, making it possible to efficiently treat and process wastewater laden with grease prior to discharge into anaerobic or aerobic digester systems. The RGF process consists of a series of specially designed reactors through which the grease is chemically treated under a fully automated program.

The Chemistry
This congealed grease from commercial grease traps must be removed periodically and disposed of by some approved method. The volume of material disposed of will depend upon the size of the traps and type of facility, which range from 75 to over 1,000 gallons. The chemistry in the process generates a reaction in which the grease is reduced to a solution, which permits it to be acceptable to the plant's digestor or headworks without chemical or biological impact.

The System

The Benefits
•This system will allow a wastewater treatment plant to professionally process grease-laden waste
water.
•Wastewater treatment plants can offset the equipment cost by charging processing fees for grease-
laden wastewater from haulers.
•The system will improve the quantity and quality of the digestor gas in an anaerobic environment.
•The system is capable of treating wastewater containing grease without affecting the performance of
the activated sludge process in aerobic and anaerobic environments.
•The system's operating cost is very low.
•Chemical costs are minimal.
•The system is fully automated and requires minimal maintenance.
•This system provides the community with a safe, healthy and environmentally friendly method of
grease disposal.
