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:
- Multimedia filter for sediment removal to 10 microns – Pentair tank, Fleck valves
- Carbon filtration for chlorine removal – Pentair tank, Fleck valves
- GE/Suez E4-H Reverse Osmosis
- Storage tank and demand pump (Grundfos CME Series) package for distribution to points of use
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.
