Web11.12 Dechlorination. Dechlorination can be achieved with sulphur dioxide (Section 12.18 ), sodium bisulphite (NaHSO 3) ( Section 12.18) or sodium metabisulphite (Na 2 S 2 O 5) ( Section 12.19) and, if required following superchlorination ( Section 11.10 ), should be carried out after chlorine has had adequate contact time for disinfection. In ... WebDe-chlorination using natural stagnant aeration (leaving the water to lose the chlorine naturally) is the safest known method if compared with chemical and charcoaling methods. ... It is concluded that shock chlorination followed by shock aerated dechlorination can produce high-quality water, zero bacterial content with zero Chlorine content.
