OWCYCLE column immersion ultrafiltration membrane products have small pore sizes and high open rates, with high flux and anti-pollution characteristics. The components adopt fiber-reinforced composite membrane technology and integrated aeration structure design, almost preventing the risk of hollow fiber breakage, reducing pollution dead corners, and achieving stable filtration of high turbidity wastewater. To be used for municipal water, municipal reclaimed water, and middle water reusing treatment, effectively removes suspended solids and microorganisms from raw water.
