Fine Filter with Stainless steel

Zerru ZSJ Precision (Security) Filter Series has a shell made of high-quality stainless steel, and the Filter Element uses molded filter material (polypropylene fiber melt-blown or wire-wound honeycomb). Under the action of pressure, the original liquid passes through the filter material, the filter residue remains on the filter material, and the filtrate flows out through the filter material, which can effectively remove impurities, sediments, suspended matter, and bacteria in the water, thereby achieving the purpose of filtration.

Product Overview

Precision filters, such as the Fine Filter With Stainless Steel and Stainless Carbon Fine Filter, are crucial components in water treatment systems. They are usually installed before pressure vessels to remove fine particles with a turbidity of more than 1 degree, ensuring the water quality meets the requirements of subsequent processes. Sometimes, these filters, including the Fine Filter Cartridges, are also installed at the end of the entire water treatment system to prevent fine particles from entering the finished water.

Most precision filters are made of stainless steel as the outer shell, providing durability and resistance to corrosion. Inside, they house filter elements like PP cotton, as seen in the PP Pure FILTER CARTRIDGES. These filters are mainly used after multi-media pre-treatment filtration and before membrane filtration equipment such as reverse osmosis and ultrafiltration.

Their role is to filter out fine substances, such as tiny quartz sand and activated carbon particles, that have passed through multi-media filtration. This ensures the accuracy of water filtration and protects the membrane filtration elements from damage caused by large particles. By selecting different filtration accuracies for the precision filter elements installed in precision filtration devices, we can ensure the accuracy of the water output and the safety of the subsequent membrane elements.
