Precision security filter – 0.5–120μm, protects RO membranes.

1. Product Overview

Aite Precision Filter (also known as security filter) mostly uses a stainless steel shell with an internal filter element

 (such as PP cotton). Aite Precision Filter is mainly used before multi-media pretreatment filtration, reverse osmosis, 

ultrafiltration, and other membrane filtration equipment. Aite Precision Filter is used to filter out fine matter after

 multi-media filtration (such as tiny quartz sand, activated carbon particles, etc.) – ensuring the accuracy of water filtration 

and protecting membrane filtration elements from large particulate matter damage.

Aite Precision Filter is available with precision grades of 0.5μm, 1μm, 5μm, 10μm, and others. Different filtration precision 

is selected according to different use occasions to ensure the accuracy of effluent and the safety of the membrane element 

after the stage.

Aite Precision Filter uses PP cotton, nylon, melt-blown, and other different materials as the filter element – removing small 

suspended matter, bacteria, and other impurities in water, so that raw water quality meets the requirements of reverse 

osmosis membrane water intake.

As a professional manufacturer specializing in industrial filtration equipment, we deliver Aite Precision Filter with stable 

performance, reliable construction, and competitive pricing for industrial facilities worldwide.

2. Technological Principle

Aite Precision Filter is a precision filter. Its working principle is to use PP filter element 5μm pores for mechanical filtration. 

Residual trace suspended particles, colloids, microorganisms, etc. in the water are intercepted or absorbed in the surface

 and pores of the filter element. With the growth of water production time, the filter element becomes polluted by 

interception, and its running resistance gradually rises. When running to the inlet and outlet water pressure difference 

reaches 0.1 MPa, the filter element should be replaced. The main advantages of Aite Precision Filter are high efficiency, 

low resistance, and easy replacement.

3. Structure and Principle

Aite Precision Filter adopts formed filter material. Under the action of pressure, the stock liquid passes through the filter

 material, the filter slag stays on the tube wall, and the filtrate flows out through the filter material – achieving the purpose 

of filtration.

Structure: Filter cloth, filter screen, filter piece, sintered filter tube, wire wound filter element, melt-blown filter element, 

etc. Because of different filter materials, filter aperture is not the same. Precision filtration is a kind of filtration between 

sand filtration (coarse filtration) and ultrafiltration, with filter aperture generally in the range of 0.5–120μm. The same form

 of filter material, according to the size of the appearance, can be divided into different specifications.

Wire-Wound Filter Element (also known as honeycomb filter element) has two kinds:

· Polypropylene fiber with polypropylene skeleton filter element – maximum use temperature 60°C

· Absorbent cotton fiber with stainless steel skeleton filter element – maximum use temperature 120°C

Melt-Blown Filter Element is made of polypropylene as raw material, formed by melt-blown process – maximum working

 temperature 60°C.

Aite Precision Filter can remove suspended solids, some colloidal substances, and small particulate matter in water.
