How to remove Chlorine (dechlorination of water) …
WebThe hexavalent chromium in this wastewater must be reduced before the water can be discharged. This requires a two-step process: hexavalent chromium (CR 6) is reduced to trivalent chromium (CR 3 ); and CR 3 is precipitated as chromium hydroxide. As the oxidation reduction potential (ORP) and the speed of the reduction reaction are closely … Webperformed. Water temperature, water composition, and reaction time also have considerable impact on the ultimate quantity of scavenging chemical needed: 252/32 = 7.88 parts pure sodium sulfite per part oxygen by weight; 190/32 = 5.94 parts of metabisulfite [becomes bisulfite in water] per part of oxygen by . weight; WebWhen dissolved in water, sodium bisulphite (SBS) is formed from SMBS: Na2 S2 O5 + H2 O → 2 NaHSO3. SBS is then reducing hypochlorous acid according to: NaHSO3 + HOCl → HCl + NaHSO4. SMBS should not be cobalt-activated. Although the dechlorination itself is rapid, good mixing is required to ensure completion; static mixers are recommended. orchard tractor for sale
