Replacement of Two-Column Deionizer with RO System for New England-Based Advanced MFR

Problem: A northern New England-based advanced manufacturing firm generated low conductivity water for several key processes with an aging two column deionizer. The unit was failing to dose hydrochloric and hydroxide properly resulting in inconsistent conductivity. With more systems coming online, the company needed additional capacity for expansion. They also wanted to move away from the HCl and OH required for regeneration of the two column system.

Solution: Pure Flow designed a 20 GPM reverse osmosis-based system to allow for increased capacity beyond the legacy deionizer and the elimination of HCl and OH at the site. The final solution included the following key components:

Pure Flow also worked with the customer to eliminate the need for on-site RO clean in place (CIP) in order to avoid any chemical discharge from the equipment. Pure Flow provide off-site 4” membrane cleanings (see Pure Flow services for details) through our facility in Peterborough, NH.
