Trustech presents real case studies that detail cooperation backgroud, challenges, tailored strategies, and key product parameters—demonstrating innovation, effectiveness, and expertise across environmental water treatment, purification, MBR, biopharmaceuticals, hemodialysis, gas separation, high-salinity wastewater, and drinking water. Spanning lab to industrial scale, solutions include TIPS/NIPS hollow fiber spinning systems and spinnerets (single-hole; FCT 2, 8, 16, 20, 32, 128 holes), dual-layer composite, braid tube–reinforced, and multi-core channel designs, as well as PI/TFC/RO flat-sheet membrane casting equipment. These technologies enable precise dope extrusion, stable flux, and anti-fouling performance, resolving industry-wide pain points and accelerating scale-up.
In 2015, while developing high performance hollow fiber membranes, Customer Motian Technology faced an industry wide challenge: TIPS spinnerets were generally limited to single hole designs, failing to meet high efficiency production needs.

To address these issues, Century Water proposed developing "dual-layer composite hollow fiber membranes," centered on a matching single-hole spinneret capable of: (i) precise synchronized extrusion of two different dopes to ensure tight interfacial bonding; (ii) combining high selectivity (inner-layer pore size 0.01–0.02 μm) with high flux (≥ 55 LMH); and (iii) enhanced anti-fouling.
