Have talked about Chlorine as a disinfectant including the working of free available chlorine as well as the combined chlorine and how they help in killing the bacteria and oxidizing organic matter. Apart from that have covered the different types of chlorination such as plain chlorination, pre chlorination, post chlorination, super chlorination, dechlorination and most important break point chlorination.

line is not start from origin in chlorine diagram

[@vikram9959]

Yes, in stage 1, destruction of micro-organisms and oxidation of minerals is carried out due to which very high demand and very minimal chlorine residual is formed.

thank u sir ..u made it interesting ...and plz post videos on other topic also ..

[@TeluguConstructionEngineer]

i like very much ur explanation
thanking u sir

[@APSEDUVERSE]

+chinna s Thanks. Let your friends also know about it who are preparing for exams :)

[@S_R21]

nice explaination...5/5

[@abhijendraanand2785]

How is the contact period defined??

[@dyutimoyghosal83]

it was wonderful..thanks a lot sir.

[@floramalinguta3732]

Very good explanation. Thank you

[@Skreddy254]

sir please upload air pollution and noise pollution lecturss

[@emmanuelsube1715]

thank you sir for your very nice explanation about chlorination reactions in water but only my question is how to convert the jar test calculations of chlorine and Alum in the laboratory into real fact in water treatment plant mathematically.

[@Cazameer1]

Agreed! The clearest explanation I've seen. Thank you!

[@v_naveen_9676]

to find demand of chlorine, with chlorine usage shall we need to add the residual cl or subtract the residual cl

[@civilology9558]

Thnks sir! 😊

[@muhammadessa3403]

what about disinfectant byproducts of chlorine? chlorine is responsible for these........

[@snehank3965]

they help to kill the bacteria for a longer run that is even they act as disinfectants and that too large time period.

[@dahiyasahab3342]

Same notes from madeeasy

[@hemalathakandasamy4297]

The additional chlorine after C is mentioned as residual of 0.2 to 0.3 mg/L of free chlorine (S.K.Garg), but you mentioned as 0.1 to 0.2 mg/L. Which is correct one?

[@civilshorts13754]

0.1 to 0.2 mg /l

[@ubuchu4299]

Good and brief explanation

[@krishnagokulwala4118]

Thankyou sir.

[@raviranjan781]

Thankyou

[@muhammadabdulmudassir4259]

Sir teach in Hindi language... For More understanding...

[@jayakanthramdhas5353]

poda punda

[@helpinghand8806]

A raw water supply of 12 x 10^6L/day to be disinfected with a chlorine dose of 1 mg/L. What will The quantity of bleaching powder containing 30 % available chlorine required (kg) for disinfection per year?

[@withpiyush]

12x365x100/30=40x365 kg

[@ronny4533]

thanks a lot sir....your explanation was very clear

[@mahendramanral4115]

Cl2 is also a free chlorine ???

[@APSEDUVERSE]

Yes!

[@saswatnayak]

What happens to HCL (Hypochloric Acid) and why should we expect ammonia in water during this process?

[@snehank3965]

HOCl you mean?
because HCl is hydrochloric acid

[@snehank3965]

Ammonia in Drinking Water. Ammonia is a colorless, pungent gaseous compound of hydrogen and nitrogen that is highly soluble in water. It is a biologically active compound found in most waters as a normal biological degradation product of nitrogenous organic matter (protein)
