E-MEM UF membrane series

Product features


Hangzhou E-MEM membrane module is widely used in the field of

dyeing and printing wastewater reuse, RO pretreatment (double

membrane process) and industrial wastewater treatment, and etc.



UF application range

In recent years, the application of UF technology can be roughly divided into the following parts:

Ø  Advanced treatment of industrial wastewater, such as reclaimed water, reprocessing of oilfield water etc.

Ø  Concentration, purification and separation of polymer solutions in the chemical, food and pharmaceutical industries, sterilization, clarification and purification of biological solutions and beverages.

Ø  Preparation of ultrapure water and pretreatment of reverse osmosis, such as groundwater treatment, surface water treatment, brackish water or seawater desalination pretreatment, drinking water treatment, boiler feed water treatment, etc.


Product performance characteristics

High strengthhigh flow rate and long life cycle

Ø  Breaking strength is above 110N

Ø  PVDF material is well-resistant to chemical washing agent and

long-term resistance to strong acid & alkali washing

Ø  The average pore distribution can guarantee the

high filtration precision of the membrane

Ø  Own patent hydrophilic modified material guarantees the stable

flow rate and good recovery ability.

Ø  Large space for pollutant storage, which makes membrane easy

Washing and enhances its applicability.


Structural design features


Ø  The loading density of membrane fiber is high

Ø  Supporting material is not necessary

Ø  Concentration polarization can be ignored

Ø  Good economic returns

Ø  Applied to various industries, especially the large-scale industry. It can reduce the floor area and the construction cost and achieve to the economic membrane design.
