Spiral Wound Ultrafiltration Membrane UPVC / Organic Glass Housing
Material
Application
1. Recycle of iindustrial wastewater(papermaking
wastewater,printing and dying wastewater,petrochemical
wastewater,steel and iron wastewater,chemical insudtry wastewater).
2. Pretreatment for NF and RO in landfill leachate treatment;
3. Electrophoretic paint treatment; liquid concentration,
separation, clarification and filtration
Features
1. The membrane silk is made of PP (polypropylene). With our unique
technology, the fiber is modified and enhanced to have high
strength and high toughness, so that it can work under a variety of
bad conditions;
2. Outer and inner diameter of the membrane silk are 500 and
400um.It is so thin that we can install more silks (about 60 ) to
72 thousand pieces, and the total membrane area is about 60m2) into
a UF shell, and suspended solids in the water can quickly plug the
cross section even when the silk is broken;
3. The filtration mode is out to in, the water to be treated can
flow into the membrane module from either side of it, makingthe
worry about wrong installation not necessary. And because of this
filtration mode, the pore on the surfaceof membrane silk can shrink
during filtering, so it can have a higher filtering precision. And
the pore will expand during backwashing, so it can wash away some
big particles to clean the membrane at the most. All of these make
our product act perfect in working process;
4. Our enhanced modified PP material has great fouling resistant
ability, and it can recover its performance by backwash instead of
chemical cleaning. It can reduce the damage to the membrane silk
and save the cost on chemicals;
The shell is made of UPVC.

| Remarks: | 1. Pure water flux is measured with pure water at the pressure of
0.1MPa. 2. If water are from surface water ,river water or well water and
so on ,pre-treatment shall be done. It is suggested that a 50-150
um precision filter shall be equipped to have inlet water with
turbidity ≤15NTU. |
Compared with other systems in this field, it has a lot of
advantages as follows:
1. With ingenious and compact design, it takes up a small area and
has a high automatic performance.
2. Clean and clear filtration water without the problems of olid
smell and getting turbid.
3. Adopting automatic control system, including automatic
back-washing, needing no one on duty, saving labor cost, solving
the problem effectively of the traditional equipments' complicated
operation and invalidation due to the operating or protecting
improperly.
4. Stable performance, long life time, low running cost.
5. Environment friendly, no second pollution.
6. More than 90% water reuse rate, no natural wastage...
