Abstract

Monosodium glutamate (MSG) was evaluated as a draw solute (DS) of forward osmosis–nanofiltration (FO-NF) process for sewage thickening. Water flux (Jw) and reverse draw solute flux (Js) through FO membrane with MSG were compared to those with NaCl as the reference DS. In addition, the influence of MSG to anaerobic digestion of concentrated sewage for methane gas production was investigated. The Js/Jw for MSG was 0.0015mol/L at 1M of initial concentration with a CTA(HTI) membrane, which was 6 % of that for NaCl, while the water flux (Jw) for MSG (ca. 10 L/m2h) was comparable to that for NaCl in FO processes. MSG recovered up to 98% by NF process, which changed with applied membrane and MSG concentration. The collected primary effluent from the full-scale wastewater treatment plant was thickened up to nine times in terms of volumetric concentration factor. The physical membrane flushing by a water could effectively recover the flux. The inhibitory effects of MSG on anaerobic methane production could be negligible and the gas production potential increased.

谷氨酸钠作为提取溶质用于污水正向渗透-纳滤浓缩

谷氨酸一钠（MSG）被评估为用于污水浓缩的正渗透-纳滤（FO-NF）工艺的汲取溶质（DS）。将MSG和NaCl作为参比DS的FO膜的水通量（Jw）和反萃取溶质通量（Js）进行了比较。此外，还研究了MSG对甲烷气生产浓污水厌氧消化的影响。在CTA（HTI）膜的初始浓度为1M时，MSG的Js/Jw为0.0015mol/L，是NaCl的6%，而MSG的水通量（Jw）（约10L/m2h）与FO工艺中NaCl的水通量相当。通过NF处理，MSG的回收率高达98%，这随着膜的应用和MSG浓度的变化而变化。从全尺寸污水处理厂收集的一级出水，按体积浓度因子计，其浓度高达9倍。物理膜冲洗可以有效地回收通量。MSG对厌氧产甲烷的抑制作用可以忽略不计，产气潜力增加。
