At Shanghai SINAP Membrane Tech Co., Ltd., we specialize in delivering robust and reliable separation membrane solutions, particularly for the world's most demanding wastewater applications. The food, beverage, and dairy sector frequently presents some of the toughest challenges due to extremely high organic and solids content. Our mission is to provide technology that not only meets but exceeds the performance required for stable environmental compliance.
The global water crisis is one of the defining challenges of our era. While continental cities grapple with infrastructure and capacity issues, small islands face a unique and existential paradox: they are surrounded by water, yet often struggle with acute freshwater scarcity and the environmental burden of wastewater discharge.
The OVOPRODUCTOS plant is an egg factory with 185m3/day capacity. Plant wastewater is from manufacturer process of the factory. The plant was an MBR plant since 2009 with hollow fiber membrane. At 2021 SINAP partner in Spain “Prosimed” changed membrane system by using SINAP flat sheet membrane into
The Konzen sewage treatment plant of the Eifel-Rur water association is equipped with membrane filtration and has 28,800 membrane plates and a filter area of 23.040 m2. The membrane plates are in double-decker module racks and are distributed over eight filter chambers. The wastewater treatment plan
In order to face the wastewater treatment needs of a small island near Athens called Agistri a compact MBR wastewater treatment plant was specified. The treatment plant is designed for 3000 equivalent people and it consists of a pretreatment phase, a Membrane Bio Reactor, a UV reactor for disinfecti

SINAP's MBR membrane roll materials represent the critical foundation for producing high-performance flat sheet filtration systems used across municipal and industrial wastewater treatment facilities worldwide. These precision-engineered PVDF (Polyvinylidene Fluoride) membrane rolls deliver exceptional dimensional consistency, with thickness tolerances maintained at ±0.01mm across full roll widths ranging from 1.0 to 1.6 meters—a specification that directly translates to reduced fabrication waste and predictable cassette assembly quality.
Our standard FS series provides reliable performance for conventional municipal MBR applications where consistent bacteria and virus removal (0.1-0.2μm pore size) meets regulatory discharge standards. For challenging industrial effluents containing elevated oil, grease, or protein concentrations, the modified PVDF variant incorporates permanent hydrophilic surface treatment achieving contact angles below 30°—dramatically reducing fouling rates and extending cleaning intervals by up to 60% compared to untreated alternatives. The enhanced PVDF formulation targets extreme conditions in petrochemical or pharmaceutical wastewater, where chlorine exposure exceeds 500,000 ppm·hours cumulative dosage yet flux recovery consistently surpasses 95% after chemical cleaning protocols.
Unlike pre-cut sheets that generate 15-25% material waste during panel cutting, continuous roll formats enable fabricators to optimize yield rates above 92%—a crucial cost factor when producing large-scale MBR installations requiring thousands of square meters. Each production batch undergoes rigorous quality verification including SEM pore structure analysis, tensile strength testing (>15 MPa), and elongation measurement (>80%), with comprehensive documentation supporting ISO 9001 and NSF/ANSI 61 compliance requirements increasingly demanded by international municipal projects.
The roll packaging incorporates aluminum foil moisture barriers and controlled-atmosphere sealing, preserving the engineered hydrophilic properties for 24-month shelf life—essential for global distribution networks serving membrane cassette manufacturers across Asia-Pacific, Middle East, and European markets. Technical support includes customized welding parameter recommendations for ultrasonic bonding systems, ensuring >80% weld strength relative to base membrane integrity.
