Membrane bioreactor organic flat sheet membrane module

1 Scope

GB/T 46604-2025 is the Chinese national standard covering the flat sheet membrane cassette in an MBR - the pore size and the flux, the strength of the sheet and its bonding to the plate, the fouling and the recovery of flux after cleaning, and the aeration below it that keeps the surface scoured. First edition, in force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026.

This document specifies the model, naming, composition, and requirements of organic flat-plate membrane modules (hereinafter referred to as "organic flat-plate membrane modules") for membrane bioreactors. Requirements, test methods, inspection rules and marking, packaging, transportation and storage. This document applies to the production, research, use, and management of organic flat-plate membrane modules for membrane bioreactors.
