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

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

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

Other Specifications: Primarily used for treating complex oil-containing wastewater, emulsion recovery to meet discharge standards, and processing of dyeing, printing, and various chemical wastewater. Combined with subsequent membrane treatment, the COD of the permeate water is less than 300, with some being safe for direct drinking. (Has been 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 pollution, 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 reach 80°C. Even when directly filtering biochemical wastewater with an active sludge concentration of up to 40g/L, the membrane flux remains as high as 80-140L/m²h, which is 5-10 times that of submerged ultrafiltration membranes, with a lifespan of over 7 years.

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