Prochem Water Reuse System Startup At Alcoa
A water reuse systems has been successfully installed and started up at Alcoa Howmet in Wichita Falls, Texas. This system will receive wastewater from ProChem’s existing wastewater treatment system to recycle the water back into the Alcoa plant.
The water reuse system is capable of accepting 75 gpm of wastewater and uses high pressure reverse osmosis (IHPRO) technology. It can supply 120 gpm of purified water to the facility. It is automated and features web-based remote monitoring.
The IHPRO unit features 8 membrane housings with 32 high-pressure industrial water reuse membranes constructed with a high surface area and high salt rejection rate. Ultraviolet light is used to control microbiological growth in the reuse water prior to distribution to the manufacturing process. In addition, a portion of the UV treated reuse water will be recirculated back to the IHPRO permeate water storage tanks to provide control of microbiological growth in the storage tank and distribution systems. Deionization columns and media are used to further purify the recycled water prior to use for higher purity needs in the plant.
The concentrate from the IHPRO unit is fed back to the IHPRO feed tanks until the concentrate meets a high conductivity level. At that point, the concentrate can be discharged to the sewer or to the wastewater treatment system for treatment.
A clean-in-place system (CIP) is included for to clean the IHPRO membranes on-site. This CIP includes a conical bottom HDPE tank, chemical feed station, and control valves and piping. Wastewater from the CIP system is directed to the wastewater treatment system for treatment (and then recycling).
