  • What is sodium metabisulphite liquid?
  • Sodium Metabisulphite liquid is used to de-chlorinate ballast waters prior to discharge to the environment. This product note describes the specification for Sodium Metabisulphite liquid. Any product supplied under this specification must meet the properties described in the attached specification.
  • Does cobalt catalyze sodium sulfite for dechlorination cause polyamide membrane degradation?
  • The reverse osmosis technical manual (PB80-186950) [ 31] said that cobalt catalyzed sodium sulfite for dechlorination results in polyamide membrane degradation. The unexamined patent publication (JPS5621604A) [ 249] mentions the pretreatment method of TFC membranes, consisting of cross-linked furfuryl alcohol.
  • Does sodium sulfite remove sulfur scales from metal surface?
  • It is also disclosed that a mixed aqueous solution containing sodium sulfite and a wetting agent effectively removes sulfur scales from the metal surface [ 237 ]. As shown in Equation (17), sodium sulfite reacts with elemental sulfur (S) and forms sodium thiosulfate (Na 2 S 2 O 3) in an alkaline solution.
  • Does SMBs reduce turbidity?
  • One method was chemical resolubilization with SMBS prior to NF. It was found that 50 ppm of SMBS could reduce turbidity from 40 NTU to as low as 3 NTU, representing over 90% reduction in turbidity. Thus, SBS could be used as a cleaning agent for sulfur and metal sulfides removal based on these data.
