Type: UF4040(PP)
4. Reference
No
Notice
1 If the membrane have be treated with hydrophilic property in dry condition, there will be
activated-agent on the membrane. Please clean the membrane by water to remove the
possible chemical agent for 30mins. The activated agent is harmless for health.
2 If the membrane have be treated with hydrophilic property in wet condition, there will
be protective water in the module. Maybe disinfection Chemical agent will be used.
Please clean the membrane by water to remove the possible chemicals for 10 mins.
3 The PP membrane have excellent properties to resist the chemicals of acid, alkaline
(HCl or NaOH) and others, but not strong enough in high concentration oxidiztive
chemicals (NaClO). Please do not keep the membren in such chemical for long time.
4 During the cross-flow and filtration, the bigger flowrate can increase the filtration and
resist the fouling of the membrane.
5 The temperature will greatly influence the UF filtration, the effluent rate will be
decreased with the lower temperature.
6 During the chemical washing, you can submerged the membren in the chemicals or
cycle the chemicals in the module for hours.
7 After the membrane has been used, please keep the membrane in wet condition all the
time. If the membrane become dry, the filtration ability will be lost.
6. Connection mode of the UF module
The UF module is outside-to-inside filtration one. There will be an "arrow" stick in the casing
of modules. On the counter side of the arrow direction, it is feed-in port. On the arrow direction,
the center port is "concentration" port, and the side port is "clean water" out port.
Hear we list two flushing ways:
The simple flushing: The flushing water will be pumped from "concentration" out port to
"feed-in" port. The effluent rate can be recovered slightly maybe.
The back-flushing: The flushing water will be pumped from the "clean water" out-port to the
"fedd-in" port. The effluent rate can be recovered greatly.But the flushing water must be clean
water or UF water.
The UF modules can be installed in horizontal direction or vertical direction.
Two or more UF modules can be used together to get more capacity of filtration. If the flushing
and air/water flushing can be done automatically, the UF modules can be keep a better filtration
for a long time.
