TheWay MBR-20 Technical Datasheet: 20 m² PVDF Module

The TheWay MBR-20 is a mid-capacity membrane bioreactor module designed for small-to-medium municipal wastewater treatment plants, decentralized treatment systems, and industrial process water applications. With 20 m² of PVDF hollow fiber membrane area, the MBR-20 offers the same proven membrane chemistry as our flagship MBR-40 in a compact form factor that simplifies installation and reduces capital costs for systems treating up to 50–100 m³/day.

Product Overview

The MBR-20 module is a submerged, vacuum-driven hollow fiber membrane unit optimized for activated sludge filtration. It delivers consistent permeate quality that meets the most stringent discharge and reuse standards. The outside-in flow configuration and hydrophilic PVDF material minimize fouling propensity while maximizing flux stability. The module's compact footprint makes it ideal for space-constrained installations, packaged treatment plants, and containerized MBR systems.

Storage and Handling Guidelines

Ship and store the MBR-20 in original packaging at 5–40 °C, away from sunlight. Maximum stacking: 4 modules. Pre-wet membranes with clean water for 30 minutes before commissioning. Perform a bubble-point integrity test at 100 kPa to confirm membrane integrity. For preservation after use, clean the module and store submerged in 0.5% sodium bisulfite solution, refreshed every 30 days. Handle with care — avoid impacts on fiber bundle ends and connections.

Frequently Asked Questions

Q: What is the daily output per MBR-20 module?

A: At 20 LMH design flux with 85% availability, each module produces approximately 9.6 m³/day. Multiple modules can be paralleled in cassettes for larger capacity.

Q: Can the MBR-20 be retrofitted into an existing activated sludge system?

A: Yes. The MBR-20 can be submerged directly in existing aeration tanks, converting a conventional system to MBR and eliminating the need for secondary clarifiers.

Q: What is the expected membrane lifespan?

A: With proper maintenance cleaning, the PVDF membranes typically last 5–8 years depending on feed water quality and operating conditions.
