- Toray introduced its PVDF plate and frame submerged MBR membrane in the 2000's.
- Familiar submerged MBR membrane element is made of macromolecule material which is well known as UF and MF.
- MBR is divided into separated MRB and submerged MBR, both have their advantages and disadvantages.
- It was also observed that the increase in sludge concentration resulted in the reduction of CFV along membrane surfaces which would influence the operation of the submerged MBR.
- Ferric hydroxide is dosed into submerged MBR and domesticated to convert activated sludge into bio-ferric activated sludge and achieved high efficiency of removal and decrease membrane pollution.
- Toray introduced its PVDF plate and frame submerged MBR membrane in the 2000's.This technology is receiving wide use in municipal as well as industrial market segments for wastewater recovery.
2000 年东丽推出了 PVDF 平板式膜生物反应器装置（ MBR 膜），此项技术在市政废水回收方面与工业市场同样被广泛使用。
