A construction equipment manufacturing plant whose manufacturing processes use approximately 50,000 gallons of fresh water per day and introduces heavy metals, chlorides, sulfates, and oil into their wastewater.

The 50K gallons of wastewater per day was being treated with an aging wastewater treatment system. The facility was experiencing high maintenance and operational costs, including off-site solids disposal, and discharge permit compliance issues. Additionally, under a corporate sustainability initiative, the facility was using a standard reverse osmosis system (for reuse) and looking for improvements to their reuse rate.

After completing the water analysis, assessing the facility's reuse potential and production goals, ProChem offered a new wastewater treatment solution with a water reuse system that was designed to fit their existing system footprint. Additionally, during the period when the facility's old system was being removed and the new one was being installed, ProChem provided a mobile, temporary treatment system so that plant production was not impacted during the transition.

The solution included a 100gpm continuous flow wastewater treatment system with physical/chemical treatment, ProChem's Metaloc technology to remove metals and reduce solid waste disposal (by 95%), and ultrafiltration to remove oils. The reuse system features ProChem's industrial high pressure reverse osmosis (I-PROTM) technology to further purify the wastewater and feed it back into the manufacturing process. Additionally, the system features ultraviolet protocols to control the microbiological growth in the storage and distribution systems.

Both systems are equipped with local monitoring and automation controls and ProChem's web-based remote monitoring service, requiring minimal operator interaction.

With ProChem's continuous flow wastewater treatment system, treatment chemicals and resins, and I-PROTM water reuse system in place, the customer is experiencing 100% discharge permit compliance in addition to an 85% wastewater reuse rate and higher quality feed water for their manufacturing process (compared to their previous standard RO and traditional treatment system).
