Scope

GB/T 43359-2023 is the English-translated version of 印染废水膜法集成装备.

GB/T 43359-2023 is the Chinese national standard for membrane-based integrated plant that treats printing and dyeing wastewater. It sets out the composition of the equipment, its technical requirements, test methods, inspection rules, marking, labels and accompanying documents, and packaging, transport and storage.

The standard defines such a unit as one combining two or more filtration processes - ultrafiltration, nanofiltration, reverse osmosis, electrodialysis - with ancillary equipment, and it applies to the production, research, testing and use of plant recovering reclaimed water and brine from dyeing and finishing effluent that has already had physical, chemical and biochemical treatment.

Among the standards it quotes are GB/T 25279-2022 on hollow-fibre curtain membrane modules, GB/T 43089-2023 on high-salinity electrodialysers, GB/T 13200 and HJ 828. Issued on 27 November 2023, it has applied since 1 June 2024.
