Brief introduction of condensate polishing prefilter
Condensate polishing prefilter filter element, Guohai pre filter filter All of them are tubular filter elements, that is, a certain number of filter elements are installed in the filter. Water enters from the outside of each filter element and flows out from the porous pipe in the center of the filter element, and impurities are trapped on the surface of the filter element. There are two main forms of folded filter element: winding filter element when laying membrane and folding filter element when not laying membrane. The accuracy of folding filter element is 10 μ m during unit start-up and 2 μ m or 5 μ m during normal operation.

Performance characteristics of pre filter element for condensate polishing:
High precision, large filtration area, large flux, small equipment diameter and less land occupation;
Internal thread connection, easy installation;
It can be cleaned and used for a long time.
Special design for backwashing operation;
High pollution interception capacity in full length;
It can provide different sizes of filter elements for powder resin filter / prefilter for various purposes;
The equipment installed with this filter element has the advantages of large output, small occupation and easy layout of main workshop;
The system is simple, without acid and alkali consumption and pollution of regenerated acid-base waste, and the waste is easy to handle, which is conducive to environmental protection;
The investment cost is low, and the pressure loss before and after condensate polishing is small.
