Filtration and Separation Technology’s electrodeposition reverse osmosis (EDRO) process uses a thin-film composite membrane to separate the aqueous phase of ultrafiltration permeate from its residual resins and dissolved ions. Built for durability, high flux rate and long life, the membrane rejects the resins and dissolved solids, creating a high-quality permeate with a flux rate said to be two to four times that of other RO membranes. The membrane also enables the EDRO system’s size and pump requirements to be 25 to 50 percent of comparable systems, the company says.
According to the company, overall, EDRO elements and systems have smaller footprints and require less energy, lower capital and less operation costs. They also offer reduced wastewater treatment and water usage, and recovery of paint resins.
