Overview
String wound cartridge filter is a kind of depth filter cartridge made by tightly winding textile fiber yarn around a porous skeleton. Its filtration precision can be adjusted by changing winding density and filter hole shape. The outside-loose and inside-tight filter aperture brings excellent deep filtration performance. With low pressure drop and high dirt holding capacity, it can efficiently capture suspended solids and fine particles from liquids. Our company strictly selects raw materials to guarantee stable chemical compatibility and reliable service life for different working conditions.
Application
This pp wound filter is used for pre filtering treatment of drinking water. It handles acid and lye liquid filtration in chemical processes, industrial chemicals and organic solvent filtration. It works as pre filter for reverse osmosis RO systems. It is also suitable for viscous fluid filtration including syrup and chocolate, developing liquid and ink filtration, pre filtration of sterile water and ultrapure water, as well as industrial water and plating solution treatment.
Features
Wire-wound filter element is made of textile fiber yarn, which is tightly wrapped on porous skeleton, and its different filtering precision is controlled by the winding density of filtering layer and shapes of filter hole.
It can withstand high filtration pressure.
It has a wide range of chemical compatibility.
A variety of materials can be used to make this filter element in order to adapt to the demand of different liquid filtration.
The structure of filter aperture with deep filtering effect is loose outside and tight inside.
With the small pressure drop and large pollutant-carrying capacity this filter element can effectively remove suspended matters and particles in liquid.

FAQ
Q1: What liquid can this liquid filter cartridge handle?
A1: It can filter water, acid, alkali, organic solvent, syrup, beverage and ink, different material options match different media.
Q2: Can it be used for RO prefiltration?
A2: Yes. This is a widely used RO prefilter, protecting RO membranes by intercepting large particles.
Q3: What is the difference between cotton wound and PP wound?
A3: Cotton wound filter with stainless steel core fits oil, beverage and medicine; PP wound is more cost-effective for acid and alkali chemical liquid.
Q4: How to choose filtration precision?
A4: 5μm and 10μm are common for RO pre-filtration; 0.5μm~1μm is for finer purification.
Q5: Is this industrial filter element customizable?
A5: Yes. Our company can customize size, material and micron rating according to your filtration requirements.
