China's Leading MBR Membrane Manufacturer
Tool-Free Installation with UniSeal™ Endcap — Designed for Compact MBR Systems
SPERTA UniSeal™ MBR membrane is designed for compact MBR systems with high resistance to pollutants. Its simple yet functional structure — sealed on one side and connected on the other — enables fast installation and easy integration. With adjustable height and a space-saving design, it is ideal for projects with limited installation space. Faster installation, lower maintenance effort, and reliable long-term performance.
Reliable hollow fiber membrane technology designed for stable operation in municipal and industrial MBR systems.
While membrane structure varies by product design, all SPERTA modules are built on the same proven hollow fiber membrane technology.
SPERTA MBR membranes are designed for submerged applications in municipal and industrial wastewater treatment plants.
Each module utilizes reinforced PVDF hollow fibers with PET inner support, providing high mechanical strength and stable operation under elevated MLSS conditions.
Operating in an outside-in filtration mode, the membranes deliver high-quality permeate with TSS below 1 mg/L.
A hydrophilic, non-ionic membrane surface reduces fouling and helps maintain stable flux, minimizing chemical cleaning frequency and operating costs.

The proprietary UniSeal™ endcap connects directly via a union fitting — no tools, no adhesives. One side sealed, one side connected. The result is a faster installation process and a simpler cassette structure compared to conventional MBR designs.
Each hollow fiber is produced via the Thermally Induced Phase Separation (TIPS) process with a PET inner support. This gives the fiber a tensile strength up to 600 N, peeling strength ≥1.0 MPa, and porosity ≥60% — engineered for high-load, long-cycle operation.
SPERTA operates dedicated MBR membrane production lines in China. Every element goes through a rigorous quality audit process before leaving the facility — ensuring consistency across every order, from sample quantities to full project supply.
Standard models range from 1,000 mm to 2,000 mm in height. Custom dimensions are available on request — making the UniSeal™ the go-to choice for retrofit projects and installations where standard-size membranes simply will not fit.
The hydrophilic, non-ionic PVDF surface resists organic fouling naturally — reducing the frequency and intensity of chemical cleaning cycles. This translates directly into lower maintenance costs and more predictable system performance over time.
The UniSeal™ single-connector design requires fewer supporting components than MBR alternatives. This reduces both the bill of materials for the cassette and the on-site labour required for assembly — lowering total installed cost without compromising performance.
The UniSeal™ end-cap enables direct module connection without tools, adhesives, or complex sealing procedures.
Compared with conventional MBR modules, the installation process is significantly simplified — reducing installation time, labor requirements, and the risk of leakage during operation.

Manufactured in our dedicated membrane production facility with strict process control to ensure consistent membrane quality and performance.
SPERTA uses high-strength braided reinforcement tubes to provide internal mechanical support for membrane fibers. Standard tensile strength reaches over 200N, with higher-strength options available upon request.
Reinforcement tubes are produced through automated continuous production lines, ensuring stable output quality and enabling fast availability through efficient inventory management.
SPERTA utilizes proprietary membrane fiber formation techniques to create a uniform PVDF layer on the reinforcement structure, ensuring consistent pore distribution and strong anti-fouling performance.
After initial performance inspection, membrane fibers are cut to required lengths based on module design specifications, ensuring dimensional accuracy for downstream assembly.
Membrane fibers are precisely potted using high-strength epoxy resin and assembled into UniSeal™ modules, ensuring reliable sealing, structural stability, and uniform permeate collection.
Each membrane module undergoes water testing to verify structural integrity and stable filtration performance before it is cleared for packaging and shipment.
Packaging is customized based on transport and project requirements — using export-grade protective crates to ensure product safety and cleanliness during international delivery.
Products are shipped globally and delivered ready for cassette assembly or direct system integration — supporting both new MBR installations and large-scale membrane replacement projects.
All membrane components are produced and inspected in-house — from fiber spinning to final module assembly. Every SPERTA UniSeal™ module is manufactured under strict quality control standards, ensuring consistent performance and reliable long-term operation.
