INTRODUCTION

The housing is made of high-quality stainless steel, possessing excellent corrosion resistance and pressure resistance. It can not only adapt to a variety of complex working environments but also provides solid and reliable protection for internal components such as filter cartridges. As the core filtering element, the filter cartridges are available in multiple materials and precisions. Common ones include polypropylene (PP) cartridges, wound cartridges, and pleated cartridges. According to different filtration requirements, they can accurately intercept suspended solids, particulate impurities, and other substances in water with different particle sizes.

The design of the water inlet and outlet ports is reasonable, ensuring smooth water flow in and out of the filter, while the sewage outlet is convenient for discharging the impurities intercepted during the filtration process. This equipment comes in a variety of specifications and can be flexibly selected according to the actual water treatment volume and filtration precision requirements. It can play an important role in everything from meeting the fine filtration needs of small laboratories and household water to serving as the preliminary filtration link in large-scale water treatment for industrial production and municipal water supply. Moreover, it is easy to install, simple to operate, and runs stably and reliably, which is the key to ensuring the normal operation of subsequent water treatment equipment and the attainment of the final water quality standards.

WORKING PRINCIPLE

The working principle of stainless steel security filters is based on the physical interception effect of the filter cartridges. When the raw water containing impurities enters the filter through the inlet port, the water flow will, under the impetus of internal pressure, evenly pass through the filter cartridges.

Due to the specific pore structure and precision of the filter cartridges, impurities in the water with particle sizes larger than the pores of the filter cartridges, such as sediment, rust, colloidal particles, and some large suspended solids, will be intercepted on the surface of the filter cartridges and cannot continue to pass through with the water flow. However, water and substances with particle sizes smaller than the pores of the filter cartridges can smoothly pass through the filter cartridges and flow out from the outlet port, thus achieving the preliminary filtration of the raw water, removing most of the visible impurities in the water that may damage subsequent equipment or affect water quality, and making the water entering the subsequent treatment process purer, laying a good foundation for the entire water treatment system.
