Wastewater Treatment For Surface Finishing & Electroplating

Wastewater treatment for surface finishing and plating operations must remove a variety of heavy metals, oils, and suspended solids before discharge to be compliant and environmentally conscious. Industrial manufacturing requiring metal finishing is steadily growing. Discharge standards are becoming more stringent to protect our environment. MacDermid Envio 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 Surface Finishers In Compliance

Surface Finishing wastewater can be especially challenging to manage given its concentration of pollutants and it’s creation of sludge. Fortunately, MacDermid Envio 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 MacDermid Envio’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 by-product known as metal hydroxide sludge. Once metals and organic materials are removed by physical/chemical treatment the resulting sludge must be removed for safe disposal. This can incur costly disposal fees, especially if the sludge contains heavy metals or potentially hazardous materials. The process of dewatering, as the name suggests, is the removal of some of the water content in order to reduce the weight of the sludge, regain useful water, or capture valuable resources from the sludge. MacDermid Envio utilizes various technologies to dewater wastewater sludge in the most efficient and cost-effective ways possible.
