Water purification systems demand zero compromise on material leaching and structural integrity. Every product in the CWS portfolio is certified to meet NSF/ANSI, CE, RoHS, and FDA 21 CFR standards.
Verified structural burst testing and heavy metal reduction (lead, arsenic, fluoride) and chlorine reduction efficacy with stabilized salt rejection exceeding 97.5%.
Compliant with Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU). Complete electrical safety and EMC noise immunity.
Zero restricted hazardous substances. Lead (Pb), Cadmium (Cd), Mercury (Hg), and phthalates (DEHP, BBP, DBP, DIBP) strictly below 1000 ppm detection thresholds.
Section 177.2470 for DuPont virgin POM resin and Section 177.1520 for food-grade polypropylene sumps. 100% potable water extraction non-toxic certification.
Before issuing the inspection release certificate for container loading, our QC engineers execute:
Filter housings, manifold plates, and POM fittings are subjected to sustained 500 PSI water pressure for 15 minutes to confirm zero structural rupture or weld seam dilation.
Cyclic pulsating water pressure from 0 to 150 PSI at 25 cycles per minute simulates 10 years of aggressive municipal water hammer fluctuations without micro-cracking.
Standardized 2000 ppm NaCl aqueous feed solution at 60 PSI operating pressure. Rejection verified with precision digital conductivity meters to ensure >97.5% salt rejection.
Titration testing on granular activated carbon (GAC) and sintered CTO carbon blocks to confirm iodine adsorption values meet or exceed 1000 mg/g.
