What is a Culligan Industrial RO System?

Culligan Industrial Reverse Osmosis systems utilize semi-permeable membrane technology to remove up to 99% of dissolved contaminants from water. By applying high pressure, water is forced through microscopic pores in the membrane, leaving behind impurities such as dissolved minerals, bacteria, particles, and organic matter. The result is high-quality permeate (product water) suitable for critical applications.

These systems are modular, skid-mounted, and designed for ease of integration into existing plant infrastructure. They are categorized into three primary series based on capacity, control features, and configurability.
