TUBULAR UF MEMBRANE
Tubular membranes are particularly suited to liquid with high viscosity or suspended solids, because their wide flow paths make them highly resistant to clogging. Tubular membranes system is an external and separated filtration system. For high solid content and viscosity liquid, we use adjustable cross-flow velocity to make the membrane run under optimal conditions and extend membrane service life. At the same time, it has more convenient cleaning, maintenance, and operation under closed pipeline.
Membranes Development：
Membrane chemical materials∶PVDF、PES、PAN、PS
MWCO range∶5,000-250,000Da
Membrane inner tube diameter∶5-12.7mm
Membrane module standard diameter∶3", 4", 6", 8",10". Standard length：3m, 3.6m, 4m
For pilot testing module standard diameter∶1~3", Length: 0.5~1.5m。
We continue membrane chemical properties development to expand the range.
Now, we can offer robust, fouling resistance and antioxidant membrane (PVDF Max. Chlorine Exposure 250,000ppm.h), acid and alkali resistance (20%NaOH), Pure water flux can be 800LMH, Max.operation pressure is10bar and max. temperature is 95℃.
Even if the activated sludge concentration up to 40g/L, the membrane flux can be 70~150LMH for domestic waste water.
Typical Applications：
Difficult waste water fields
Landfill leachate pretreatment
Pretreatment for alkali liquor recycle
Special chemical waste water (Coking, Tannery, textile, wood pulp bleach) treatment
Return injection of produced water from oil field
Emulsified oil treatment
Specialty fields
Fruit juice and tea drinks clarification
Food and bio-pharmaceutical fermentation clarification
