China's Leading MBR Membrane Manufacturer
Pre-Assembled MemCass™ Cassette System for Faster Installation and Reliable Operation
SPERTA MBR cassette systems integrate membrane modules, frame, and piping into a ready-to-install unit.
Designed for both new projects and retrofit upgrades, they help reduce on-site installation time, simplify system integration, and support stable long-term operation.
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 above models are standard reference configurations. For projects with specific treatment capacity or tank dimensions, SPERTA provides project-specific MemCass™ cassette sizing — please contact our engineering team to discuss your requirements.
Each MemCass™ cassette integrates membrane modules, structural frame, aeration system, and permeate piping into a compact and stable unit.
The cassette combines membrane modules with a rigid stainless steel frame, ensuring structural integrity and long-term durability under continuous operation.
Pre-aligned module positioning reduces installation complexity and improves system reliability from day one.
The cassette design ensures uniform flow distribution across all membrane modules, improving filtration efficiency and reducing localized fouling.
Balanced hydraulic conditions support stable system performance and predictable effluent quality over time.
Built-in aeration piping enhances membrane surface scouring, reducing fouling and maintaining stable flux during continuous operation.
The integrated design minimizes additional installation work on-site and improves overall system energy efficiency.
A centralized permeate collection system ensures consistent suction across all modules, improving system balance and filtration stability.
This design simplifies piping layout and reduces the risk of uneven operation across the cassette.
SPERTA cassette systems are designed for easy integration into both new builds and retrofit projects, with flexible configurations to match existing tank dimensions.
This reduces engineering effort, shortens project timelines, and lowers total installed cost.
Pre-assembled and ready to lower into the tank — see how MemCass™ simplifies on-site installation.
The MemCass™ cassette arrives on site fully assembled — membrane modules, stainless steel frame, aeration piping, and permeate collection integrated into one unit.
The cassette can be lifted directly into the MBR tank, connected to the aeration and permeate lines, and ready for operation.

Each MemCass™ unit is engineered, assembled, and inspected through a controlled process — ensuring quality, consistency, and readiness for on-site installation.
Project drawings are finalized based on required capacity, tank dimensions, and installation layout — ensuring every unit is built to the exact project specification.
Appropriate materials and components are selected to ensure structural strength, corrosion resistance, and long-term durability under continuous operation.
The cassette frame is fabricated and welded according to the approved design, ensuring dimensional accuracy and structural stability throughout the service life.
The frame undergoes cleaning and acid treatment to improve corrosion resistance, extend service life, and ensure a clean interface for membrane installation.
Key components including connectors, aeration pipes, and supporting structures are assembled onto the frame with precision alignment.
Membrane modules are installed with proper alignment and spacing to ensure uniform flow distribution and stable filtration performance across the cassette.
Each unit is inspected to verify assembly integrity, connection reliability, and overall completeness before it is cleared for packaging.
Units are securely packed in export-grade protective crates to prevent damage during transportation and delivered ready for on-site installation.
From drawing confirmation to final packaging, every MemCass™ unit is manufactured under a controlled 8-stage process. Each unit is delivered fully assembled and ready for lifting, installation, and operation.
