Sunresin touts NSF-certified PFAS resin for drinking water systems

Sunresin New Materials Co. Ltd. is promoting certified ion exchange media designed to help municipal water systems remove PFAS while meeting drinking water safety standards. The company says its resin and EPC services are built to support compliance, pilot testing and full-scale deployment.

Why it matters: - Municipal water systems are under growing pressure to remove PFAS without creating harmful byproducts in finished water. - Drinking water operators need materials that meet health standards, perform under real-world flow conditions and avoid secondary contamination. - Certification and batch traceability matter because treatment media can affect both water quality and system reliability.

What happened: - Sunresin New Materials Co. Ltd. presented its PFAS resin offering as an NSF-certified solution for potable water treatment. - The company highlighted SEPLITE® LSI106G, an anion exchange resin aimed at PFAS removal in municipal water applications. - Sunresin pointed readers to its product and company pages: Advanced NSF Certified PFAS Resin Solutions Provider, SEPLITE® LSI106G, Sunresin company profile, and more information.

The details: - NSF/ANSI/CAN 61 is described as the benchmark for evaluating drinking water material safety. - The standard tests whether media releases unreacted monomers, residual catalysts, heavy metals or volatile organic compounds into water. - The text says NSF 600 health effects criteria now tighten allowable leaching limits to single-digit parts-per-billion or parts-per-trillion levels for single contaminants. - Certified media is also tested for structural stability under hydraulic flow. - Weak polymer matrices can shed microscopic resin fines, create head-loss problems and damage downstream filtration assets. - Certified media is intended to resist osmotic shock and mechanical shear. - SEPLITE® LSI106G uses a macroporous polystyrene matrix with quaternary ammonium groups, including tributylamine functionalities. - The resin is designed to combine electrostatic attraction and hydrophobic interactions. - The media is intended to capture long-chain PFAS such as PFOA and PFOS, as well as short-chain compounds such as PFBA and PFBS. - The functional group arrangement is intended to reduce short-chain displacement and support non-detect targets. - The resin is said to maintain selectivity in water with competing anions such as sulfates, nitrates and chlorides. - The operating range given is 20 to 40 bed volumes per hour. - The reported Empty Bed Contact Time range is 1.5 to 3 minutes. - Sunresin says its automated synthesis facilities are certified under ISO 9001 and ISO 14001. - The company says computer-controlled polymerization keeps temperature, agitation and crosslinking density tightly regulated. - The company says the process achieves a whole-bead count of 93% or higher and particle size distribution between 0.35 mm and 1.25 mm across more than 95% of batches. - Sunresin says its annual resin manufacturing capacity exceeds 50,000 cubic meters. - Each certified batch is tested for operating capacity, moisture retention and mechanical bead strength. - The company says it maintains full supply chain traceability for every production lot. - Sunresin says its EPC services include skid-mounted filtration units, automated control systems and corrosion-resistant pressure vessels. - The company also says mobile pilot skids can be used to test resin performance under real water conditions before full-scale commissioning.

Between the lines: - The pitch is not just about resin chemistry. It is also about proving compliance through certifications, testing and documentation. - The emphasis on pilot skids and EPC integration suggests utilities want lower implementation risk before committing to full-scale capital projects. - The company is positioning itself as both a media supplier and a systems integrator, which can simplify procurement for municipal buyers.

What's next: - Consulting engineers, utility directors and procurement teams can review technical specifications, compliance certificates and pilot testing guidance through the company’s website. - Sunresin is offering pilot evaluation services and full system design support for projects that need PFAS treatment media. - The company says it will continue to support municipal drinking water, groundwater remediation and industrial wastewater applications worldwide.

The bottom line: - Sunresin is betting that certified, traceable PFAS resin paired with EPC support will appeal to water systems that need compliance, performance and faster deployment in one package.
