ro Pure water front security filter

Equipment introduction

ro pure water pre security filteris widely used in various industries in the field of high precision water treatment filtration. Different specifications and models of Fujian ro pure water pre security filter can meet the requirements of water treatment pre pretreatment, and can handle the application scenarios of large processing capacity of 2 tons per hour to more than 100 tons per hour.

Product characteristics

ro pure water front security filter is divided into: ring nut type, clamp type, flange type.

Characteristics are: ring nut type: good sealing, relative to the flange type replacement filter element more convenient.

Clamp type: easy to install, cheap, withstand pressure less than 0.6Mpa.

Flange type: good sealing.

Filter shell material: SUS304/SUS316/SUS316L stainless steel;

The material of filter element: wire wound filter element, melt-blown filter element, microporous filter element and multifunctional filter element

Sealing ring material: polyethylene, rubber;

Sealing material: rubber, silicone, fluorine rubber, standard configuration for silicone seal.

Different materials of parts have different prices, the selection of parts material is also according to the actual use requirements to choose.

Product composition

ro pure water pre-security filter forming filter materials are: filter cloth, filter screen, filter, sintered filter tube, wire wound filter element, meltjet filter element, microporous filter element and multifunctional filter element. Because of the different filter material, filter aperture is not the same. Security precision filtration is a kind of filtration between sand filtration (coarse filtration) and ultrafiltration, filter aperture is generally in the range of 0.1-120um. The same form of filter material, according to the dimensions and divided into different specifications.

Selection rule

1. import and export diameter

In principle, the filter inlet and outlet diameter should not be smaller than the matching pump inlet diameter, generally consistent with the inlet pipe diameter.

2. Nominal pressure

Determine the pressure level of the filter according to the higher pressure that may occur in the filter line.

3. the selection of the number of holes

Mainly consider the size of impurities to be intercepted, according to the medium process requirements. Various specifications screen can intercept the particle size check the table "screen size".

4. Filter material

Generally, the material of the filter is the same as that of the process pipe connected. For different service conditions, cast iron, carbon steel, low alloy steel or stainless steel filters can be considered.

5. filter resistance loss calculation

For water filters, the pressure loss is 0.52 ~ 1.2kpa at the rated flow rate.

Application industry

Security filter is mainly used in nanofiltration, ultrafiltration, reverse osmosis, electronic membrane deion, and other system security filtration, pharmaceutical injection, infusion, eye drops, Chinese herbal medicine and other filtration, biological preparation extraction, purification, concentration, electronics, microelectronics, semiconductor industry with high purity water pre-filtration, Oil field water, boiler water, chemical reagents, liquid organic products, high purity chemicals, concentrated medicine filtration, drinking water, mineral water, fruit juice, tea drinks, health drinks filtration.
