EZ-BLEACH®
On-line Analyzer System for Sodium Compounds in NaOCl
EZ-BLEACH® on-line analyzer system for the determination of sodium hypochlorite (NaOCl), sodium carbonate (Na2CO3), sodium hydroxide (NaOH) and sodium chloride (NaCl) in sodium hypochlorite (NaOCl)
- Monitor reactor sodium hydroxide (NaOH) concentration: starting from 20% - min. 4 to 6%
- Monitor hypochlorite or bleach (NaOCl) concentration: max. 170g/l NaOCl
- Monitor sodium chloride (NaCl): 1 – 30g/kg NaCl
- Monitor sodium carbonate (Na2CO3): 1 – 10g/kg Na2CO3
Description
Absorption of chlorine in sodium hydroxide for chlorine destruction and production of sodium hypochlorite or bleach (NaOCl)
2 NaOH + Cl2 → NaOCl + NaCl + H2O
In case of excess sodium hydroxide consumption the sodium hypochlorite (NaOCl) will be decomposed:
@pH 8 NaOCl → NaCl + ½ O2 DANGER Gas production Ph T°h
@pH 9 – 10 3 NaClO → 2NaCl + NaClO3
