Hydranautics CPA-4040E High-Rejection RO Membrane
The Hydranautics CPA-4040E is a professional-grade 4-inch reverse osmosis element designed for applications requiring exceptionally high levels of water purity. As part of the CPA (Composite Polyamide) product line, it has become a trusted industry standard for desalting brackish water to produce high-quality permeate for municipal and industrial use. This element is specifically valued for its ability to provide consistent performance in a variety of light industrial systems, including power generation, pharmaceutical production, and semiconductor manufacturing.
Constructed with a composite polyamide polymer in a spiral-wound configuration, the CPA-4040E is engineered to deliver high rejection of Total Dissolved Solids (TDS), silica, and hardness. It features an active membrane area of 65 square feet and a 34-mil feed spacer, which enhances the element's tolerance to suspended solids and improves overall cleanability. With a nominal salt rejection of 99.5% and a permeate flow rate of 2,250 gallons per day, this membrane provides a reliable and cost-effective solution for producing ultrapure water from challenging feedwater sources.
