Automotive & Heavy Industry

Manufacturing automobiles, construction machinery, and agricultural equipment often generates a variety of messy byproducts. Even the manufacturing of the components such as axles, radial tires, and engines which comprise these machines produce waste. Likewise, manufacturing plants harbor numerous contaminants, such as oil, heavy greases, lubricants, and metal finishing. Other harmful pollutants found at worksites include dirt, molten salts from heat treatment, as well as dirty, oily water. Due to the potential hazard these contaminants pose, wastewater treatment is necessary for proper filtration.

DMP Corporation specializes in wastewater treatment systems for automotive and other manufacturing sectors, making us a valued partner for many industrial applications. Our company offers a wide range of technologies and chemistries that render wastewater safe for reuse, providing critical versatility that suits the demands of your business.

Water Treatment Solutions for Heavy Industry

In a manufacturing plant that focuses on engines, axle rebuilds, or other automotive processes, the primary contaminants are oil, grease and other lubricants that must be filtered out during wastewater treatment. Other pollutants include dirt and grime or heat treatments in molten salts – not so much dissolved metals or Biological Oxygen Demand load, just dirty, oily water. Hydrocarbons removal can be challenging, but DMP has a variety of technologies and chemistries at its disposal to render that wastewater safe for recycling and reuse.
We frequently provide solutions for manufacturers in the following industries:


A multitude of manufacturing processes in the automotive industry produce wastewater. Some of the generators of wastewater include painting and coating, vehicle washing, airbag and air conditioning system manufacturing, rubber tire manufacturing, vehicle component fabrication, bearings and brake manufacturing, metal finishing, and much more. The treatment of this high volume of wastewater must adhere to stringent environmental regulations.

Ultimately, wastewater treatment maximizes a variety of manufacturing elements, such as:

  • Production efficiency
  • Heat transfer and cooling
  • Water flow and quality
  • Water reuse capabilities

Automotive wastewater treatment also minimizes corrosion, equipment blockages, and chemical costs. Alongside these benefits, it also protects against biofuels, significantly prolonging equipment life by protecting against service disruptions or critical system failures.


Fabricating equipment for the transportation sector generates wastewater contaminated with greases and oils, similar to automotive manufacturing. In addition, equipment across all transportation mode—including air, highway, rail, sea, and waterways—must be durable with a long service life, which often involves specialized metal finishing treatments for large-sized components, which can generate significant wastewater. It’s important for manufacturers of transportation equipment to implement comprehensive wastewater treatment solutions that can handle the variety of specialty chemicals in the wastewater they generate.

Machinery for Building and Construction

Water is also a key component of many construction projects, such as excavations and establishing foundations. Likewise, water serves well to cool construction equipment operating at extreme heats, such as drilling rigs, boring machines, cutting machines, among many others. Unexpected rain during a construction project may also cause effluent seepage. To prevent effluent seepage into a public stream or settling into the soil, wastewater generated by construction sites must receive appropriate consideration.

Agricultural Machinery

Crucial for farm management, agricultural wastewater treatment helps to sustain the productivity and longevity of a farm business. Wastewater treatment controls surface runoff, which contains many harmful contaminants such as pesticides, fertilizers, crop residues, manure, and irrigated water. Sediment and nutrient runoff also contribute to agricultural pollution. Excess sediment runoff negatively impacts aquatic biodiversity. Likewise, nutrient runoff contains harmful chemicals such as nitrogen and phosphorus. With wastewater treatment, agricultural machinery and farming methods can work at their maximum production potential, alongside the environment.

Automotive & Heavy Industry Wastewater Solutions from DMP Corp.

Much of the Clean Water Act in 1972 came about in large part as a response to the high levels of wastewater produced by automotive, transportation and heavy machinery manufacturers. It was that demand that allowed DMP to thrive as we offered our solutions and expertise to plants and facility in need of better wastewater management. At DMP, we specialize in helping our clients meet all required federal, state, and local wastewater requirements.

With over 50 years of experience, DMP understands the vast range of wastewater management needs in heavy industry. Working closely with your business, we will find the appropriate equipment, controls, and chemicals to best integrate into your existing production process.
