A Journey of Progress Towards Purer Water

Proudly utilizing our proprietary Vacuum Swing Adsorption (VSA) technology, our PCI DOCS signify a revolutionary leap forward in water treatment solutions. Engineered with precision and innovation, our cutting-edge Deployable Oxygen Concentration System (DOCS) is purpose-built to provide distinctive and efficient solutions that not only meet but exceed the critical needs of water treatment across various sectors, establishing a new standard in oxygen generation technology.

The Clapper Road Water Treatment Plant (WTP) in Bethlehem, New York, embarked on a mission to improve plant performance, enhance water quality, meet EPA requirement, and address on-going dissolved oxygen deficiency in the raw water. PCI, a leader in oxygen and nitrogen generators, and Mazzei Injector Company technologies were selected by the Hazen engineer to help effectively solve these problems in order to comply with more stringent EPA requirement.

VSA Technology

To produce oxygen from air, PCI uses a proprietary Vacuum Swing Adsorption (VSA) process that eliminates many of the design problems associated with traditional on-site gas separation systems (PSA). Our innovative VSA system eliminates the need for process valves, feed air compressors, associated dryers and feed air filtering systems. Our robust VSA oxygen process extracts maximum sieve and power efficiencies = low cost (both CapX and OpX) high purity oxygen generation. Oxygen produced is 93% purity. Additional product/systems features include load following, remote monitoring and diagnostics along with an industry only 10-year warranty on the adsorber bed vessel. Average life span of our systems is 10-15+ years.
