Industrial SS water security filter for mineral water

The introduction of Stainless steel security filter:

Precision filtration devices (also known as security filters) are mostly made of stainless steel with a filter element (such as PP cotton) inside. They are mainly used after multi-media pretreatment filtration and before membrane filtration equipment such as reverse osmosis and ultrafiltration. It is used to filter out the fine materials after multi-media filtration (such as tiny quartz sand, activated carbon particles, etc.) to ensure the water filtration accuracy and protect the membrane filter elements from damage by large particles. The precision level of the filter element installed in the precision filter device can be divided into 0.5μs, 1μs, 5μs, 10μs, etc. Different filtration precisions are selected according to different use occasions to ensure the accuracy of the subsequent water outlet and the safety of the subsequent membrane elements.

The Process principle of Stainless steel security filter:

The security filter is a precision filter, and its working principle is to use the PP filter element with 5μm pores for mechanical filtration. The trace suspended particles, colloids, microorganisms, etc. remaining in the water are trapped or adsorbed on the surface and pores of the filter element. As the water production time increases, the operation resistance of the filter element gradually rises due to the pollution of the trapped material. When the water pressure difference between the inlet and outlet reaches 0.1MPa, the filter element should be replaced. The main advantages of the security filter are high efficiency, low resistance and easy replacement.
