    after giving different chlorine dose in a liter different beakers how much time should I wait for residual chlorine test ( titration)

    Can u tell what here is residual chlorine n free🙄 chlorine. Does it means that first one is referred to chloramine n latter one to hypochlorite n hypochorous ion

      when you add chlorine to water then the chlorine present in water is residual chlorine which is initially combine chlorine after breakpoint the residual chlorine is free residual chlroine.

    I have a question: is the chlorine dosing amount related 1:1 with the amount of Iron, Nitrite and Manganese in the water?

      Yes I think mostly, but if the bacteria rate is important the amount of hypochlorous acid or OCl will be depleted

    Hi AWC. Just a quick question. I have a larrge pond, that has alklainity of 100ppm, pH of 8.5, and is filled with bacteria. I am planning to add calcium hypochlorite into it. I understand at high pH most of the form of the hypochlorite ion will be in the less favourable form, hypochlorite, and very little hypochlorous acid will be there. Now, since hypochlorous acid is much much more effiecent (80x) at kiling bacteria, i assume once added, its concentration will be depleted quite quick. Since it is in equilibrium with hypochlorite ion and H+, so wont the equilibrium respond by shifting left, thus increasing the concentration of the hypochlorous acid and thus reducing the concentration of the hypochlorite ion?

      It would be better to use bromine in this application due to it's greater efficacy in a higher pH range compared with chlorine. This is usually released from a solid donor called BCDMH (bromo-chloro-dimethyl-hydantoin), commonly referred to as "bromine tablets". It can be dispensed using a tablet feeder much like "chlorine tablets".

    All clear except the part where the chlorine residual actually decreases. More specific explanation would be good there, to show the mechanism.

    • @otw5974
      @otw5974 Рік тому

      The red line represents 'total chlorine'. Chloramines, formed as disinfection byproducts (DBPs) during the initial disinfection activity (oxidation) of impurities (oxidant load), are further oxidised as hypochlorite is added, creating 'combined chlorine', and reducing the total chlorine level - stages 3-4. The breakpoint is the stage at which the total chlorine level is predominantly in the form of FAC and has oxidised the oxidant load, and thus the concentration of FAC can now begin to build relative to the quantity of hypochlorite ('chlorine') added.

      @@twinkieerella Thank you for the answer. I understand that. It just isn't clear how exactly they are destroyed. Surely there must be a chemical reaction going on that renders the materials "destroyed". Would like to know the details
