CONCENTRATION AND MEMBRANE COMPONENTS
  •         Membrane filtration is a screening process which is related to the pore size,motivated by the pressure difference between two sides of membrane,with membrane as filtration media,under some pressure,when the stoste flows through the surface of membrane,only water and micro-molecules are permitted to pass through the micro pores,while the substances larger than micro pores on the surface of membrane are intercepted on the side of inlet solution,and becomes concentrated solution,thus achieving the separation and concentration of stoste.
Features

◎ -Separation and concentration under normal temperature and low pressure lead to low energy consumption,and low running cost of equipments.
◎ -Small volume equipments,simple structure,and low investment cost.
◎ -The process of membrane separation is a simple process of transmitting liquid under pressure,technological process is simple and easy to operation and management.
◎ -As a kind of filtration media,membrane is homogeneous non-individual body made from high molecule material,with physical methods of filtration,there is no qualitative change in the process of filtra tion.

Wide application
        The above features contribute to the wide application of membrane concentration and separation. According to the measurement of separated granule or molecules and the structure of the membrane,the process of membrane separation are divided into MF,UF, NF and RO. The PP MF membrane components and PES UF membrane components with different intercepted molecules flux are widely applied to organic concentration and separation in industry, such as chemical industry, pharmacy, biotechnology and so on. Moreover, as re-treatment technology of RO, they could be applied in the field of concentration and separation.
