DMP Upgrades Aerospace Wastewater System & Improves Rinse Water Quality

Wichita, KS

Background

Manufacturers need capable wastewater treatment solutions

Aerospace facilities are among the most high-tech plants in manufacturing and require efficient, effective wastewater treatment systems. However, even the top aerospace manufacturers and suppliers can find it difficult to make good wastewater treatment decisions due to the complicated nature of the many processes involved in their manufacturing processes. There’s also an opportunity to use treated city water and wastewater to produce higher quality products. As an approved supplier to nearly 20 aerospace manufacturers at multiples facilities all over the country, DMP Corporation is the ideal wastewater treatment partner.

Challenges

Antiquated system foils aerospace manufacturer’s wastewater treatment

A large Wichita-area aerospace manufacturer with five types of metal finishing lines (anodizing, pre-penetrant etches, chemical film, passivation, and other) could not provide enough high-quality rinse water to meet their product demand. In industries involving metal plating and surface finishing, it is important to have high-quality water. Many times, even city water must be treated before use. Their existing 20-year-old wastewater treatment system had been repaired many times and was incapable of increased capacity too. Further, the pure water system could not produce enough clean water for rinsing.

The aerospace manufacturer knew of DMP Corporation’s excellent local reputation through other industry firms. They contacted us with the goals of increasing rinse water quality and quantity and meeting discharge limitations without losing production time.

Solutions

Integration of legacy equipment reduces upgrade costs and staged installation minimizes production delays

DMP performed a complete water survey of the facility. We sampled all process lines and observed daily operations. We analyzed many samples at no cost and drew on our experience to develop the design.

The project was delayed several times as facility ownership changed, but the problems did not disappear—a large increase in aircraft production (a good problem to have!) further increased the facility’s workload. DMP proposed a staged installation schedule to minimize production delays. As planned, the project was installed successfully without loss of production.

Our main recommendation was to re-pipe a portion of the facility to separate low-Total Dissolved Solids (TDS) and high-TDS rinses. Low-TDS rinses would be processed in an efficient water recycling system and high-TDS rinses would be combined with spent chemical baths, treated in a new conventional wastewater treatment system and discharged. To reduce costs, a large portion of the existing equipment was included in the new DMP design.

Results

High-quality products made possible with proper rinse water

With DMP, the aerospace manufacturer:

  • Yields more efficient, less operationally disruptive wastewater treatment using existing equipment
  • Continuously meets their discharge limits
  • Recycles a large portion of their high-quality treated water, cutting costs

DMP can recommend and implement solutions in a cost-effective manner. Part of DMP’s guarantee is to provide continual service as needed through remote monitoring and chemical delivery. As the facility’s new system was installed and implemented, DMP was there every step of the way.

For operations that want optimized wastewater treatment as well as minimized operating costs, DMP Corp offers the premier solution. Visit DMP’s wastewater solutions page to learn more about their methods to cut costs and increase operational efficiency.
