The molecular weight cut-off for our single-core tubular ultrafiltration membrane is 120,000. The membrane material is modified PVDF, with a high operating pressure of 6.2 bar. The membrane tube has a diameter of 25mm and a length of 1120mm, with a single membrane area of 0.2m². Each tube can be used in series with 12 others, and the average energy consumption of the equivalent system is 1/4 that of ceramic membranes.

Primarily used for the treatment of complex oil-containing wastewater, recovery of emulsified liquids to meet discharge standards, and processing of dyeing, printing, and various chemical wastewater. Combined with downstream membrane treatment, the COD of the permeated water is less than 300, and some can even be consumed directly. (Has been successfully applied in the US for nearly 20 years.)

We offer seven-core tubular ultrafiltration membranes with a molecular weight cut-off of 100,000. The membrane material is modified PVDF, and the high operating pressure is 4.8 bar. The diameter of the membrane tube is 11mm, the length is 1120mm, the area of a single membrane is 0.67m², and a single membrane tube can be used in series with 12 others. The average energy consumption of the same system is 1/5 of that of ceramic membranes.

Other Specifications: Primarily used for treating complex oil-containing wastewater, emulsion recovery for compliant discharge, as well as for the treatment of dyeing, printing, and various chemical industrial wastewater. When combined with subsequent membrane treatment, the COD of the permeated water is less than 300, and some of it can be safely consumed. (Successfully applied in the U.S. for nearly 20 years.)

Yu Wang Company offers PES and PVDF tubular ultrafiltration membranes with tube diameters ranging from 5mm to 12.5mm. The tubular membranes feature excellent strength, resistance to contamination, oxidation, and acidity/alkalinity (pH 1-13), with a pure water flux of up to 750L/m2h. Operating pressure can reach 10bar, and the working temperature can be as high as 80°C. Even when directly filtering biochemical wastewater with an active sludge concentration as high as 40g/L, the membrane flux remains as high as 80-140L/m2h, which is 5-10 times that of immersed ultrafiltration membranes, with a lifespan of over 7 years.

Features: Membrane tube diameter 8-13mm; High filling density: strong anti-fouling ability, easy to clean.
