Water Treatment
In compliance with CFR Title 40 Part 442, the Transportation Equipment Cleaning Point Source Category, we utilize a combination of technologies for our waste water pretreatment systems that meet or exceed our monitoring and testing requirements. We use a combination of decanting, chemical precipitation, dissolved air flotation, membrane separation, and centrifugal dewatering, depending on the facility location. The technologies utilized, operator know-how and systems integration of these technologies will ensure our path of sustainability.
Recycling
Drumm, Inc.'s recycling capabilities have proudly kept our customers disposal costs down over the years. Our oil and fat recycling systems are integrated as part of our cleaning operations and use a combination of decanting, heat cracking, and centrifugal separation. Recovered bio-solids containing valuable levels of phosphorus, nitrogen, and pot ash is used as fertilizer for corn and soybean crops. We have reports of fantastic yields from this reuse. This sample of recycling originates in waste water and keeps a good reusable by-product out of our landfills. Lab certified testing is done to ensure a safe product per the standards applicable to the reuse.
Solid Waste Handling
Non-recyclable by-products are profiled and disposed of, to an approved landfill, as non-hazardous waste per EPA's RCRA regulations. We determine the best process to efficiently dewater wastes that are above the moisture requirements set by haulers. The technologies we most commonly use are dewatering by centrifuge, polymer or saw dust solidification.
