Successful cases in Spain how to improve the filtration efficiency of 304 stainless steel pleated cartridge

This article shares the complete case of custom development of 304 stainless steel pleated cartridge for a water enterprise in Spain. Through the three core advantages of material selection, structural optimization and rapid response, we successfully solved the technical problems of the customer in the 10-micron filtration, and the project was delivered to achieve a flow rate increase of 23% and a service life extension of 40%.

Food-grade materials to ensure safety standards According to the high chlorine content of the customer's water, 304 stainless steel mesh material in accordance with ASTM A240 standards is used, and its corrosion resistance is verified by salt spray test. The folding process extends the filtration area to 0.65 square meters (35% more than conventional products), with 316L stainless steel skeleton to ensure stable operation in the PH value of 6-9 range. The third-party testing report shows that after 2000 hours of continuous operation under simulated working conditions, it still maintains 98.6% of the initial filtration efficiency.

Bidirectional flow structure optimizes fluid mechanics Aiming at the special size requirement of 129×84.7×280.3mm, the two-end open design is adopted to realize bidirectional water intake. Verified by CFD fluid simulation, the structure reduces the pressure loss to 0.12MPa (industry average 0.18MPa), and with the 60-layer precision folding process, it still maintains a stable flow rate of 18m³/h at 10 micron precision. Installation tests show that the design improves backwashing efficiency by 40% and effectively prevents cartridge clogging.
