OBrien & Gere has introduced its ARROW (Advanced Reject Recovery of Water) solution, an advanced membrane-based process for water treatment. ARROW purifies water and wastewater using reverse osmosis membranes, ultimately reducing reject volume up to 100%. ARROW is applicable to any flow range, and is capable of meeting high-purity water requirements with additional downstream polishing.
The benefits of utilizing ARROW are far-reaching: improved water quality, higher treatment efficiency, reduced disposal costs, and lower operating rates. ARROW equipment is compact, pre-assembled, and skid-mounted, and perfectly suited for the treatment operations of a wide array of industries: chemical, pharmaceutical, food and beverage, power, metals, automotive, and municipal. With a proven record of success for a diverse range of clients, ARROW offers a cost-effective way to optimize the purification process while significantly reducing water waste.
