Immersion PVDF ultrafiltration membranes

Submerged hollow fiber ultrafiltration membrane

Products Introduction

• Submerged hollow fiber ultrafiltration uses specific encapsulation technology to seal ultrafiltration membrane in components, directly submerged in the water to be treated, negative pressure or gravity in the membrane to generate a vacuum, the membrane surface on both sides of the formation of the driving force, through the mechanical sieving and adsorption of the membrane pores make the water purification.

Product features

• Submerged ultrafiltration membrane module adopts PVDF hollow fiber ultrafiltration membrane, adopts open filtration, reduces the requirement of influent pretreatment, and reduces the footprint of the whole installation. It has become another new type of membrane application technology after pressure ultrafiltration.

Product Advantages

• Fully open design with large flux, high strength, drug-resistant washing and other characteristics, reducing pollutant deposition.

• Membrane organization as a whole submerged in the wastewater, aeration and water collection integration reduces the pipeline and bracket. Installation and maintenance of time-saving and labor-saving, reducing the membrane pool footprint.

• Periodic backwashing and membrane pool aeration can effectively reduce membrane surface contamination, low-frequency chemical on-line cleaning, which is conducive to eliminating the depth of membrane contamination, to ensure the long-term stable operation of membrane system.
