Metal Plating & Finishing

Wastewater treatment for metal finishing and plating operations must remove a variety of heavy metals, oils, and suspended solids before discharge in order to be compliant and environmentally conscious. Industrial manufacturing is growing quickly and discharge standards are becoming increasingly more stringent. DMP understands the need for more efficient and cost-effective methods for removing these wastes, and has built systems for over forty years that help metal finishing operators remain compliant and competitive.

Keeping Metal Finishers In Compliance

Metal wastewater can be especially challenging to manage given its concentration of pollutants and it’s creation of sludge. Fortunately, DMP has developed metal removal solutions and systems suitable for small finishing shops to sprawling aerospace manufacturers. The technology we’ve developed is perfectly suited for a wide variety of waste streams throughout the metal finishing industry, including those resulting from captive plating, phosphatizing, anodizing, chrome conversion, parts washers, vibratory deburring, E-coat, and more. We manufacture the critical components and supply complimentary chemicals to keep your systems running smoothly and within compliance.

Our best of breed solutions help DMP’s customers realize long-term efficiencies, stringent environmental compliance and overall positive impact to their bottom lines.

Sludge Management

Most metal plating and finishing wastewater treatment processes produce a byproduct known as sludge – typically solids that fall to the bottom of the liquid waste stream. The sludge must then be removed and can incur costly disposal fees, especially if the sludge contains potentially hazardous materials. The process of dewatering, as the name suggests, is the removal of some or most of the water content in order to reduce weight, regain useful water, or capture valuable resources from the sludge. DMP utilizes various technologies and methodologies to dewater wastewater sludge in the most efficient and cost-effective ways possible.
