The CORNCOB-II high-velocity crossflow (HVCF) rotating disc membrane system from Pro-Equipment helps eliminate conventional pretreatment, increases the throughput flux (gpd per square foot) and reduces operating energy. Applications include treatment levels from microfiltration to reverse osmosis. It attains a high crossflow velocity across the membrane surface with minimum energy input, achieving high flux rate while accommodating high solids content. It is a meshed rotating disc system with membrane-supporting discs mounted on two or more adjacent shafts where the discs on one shaft fill the space between discs on the adjacent shaft. 262/513-8801; www.proequipment.com.
