There are several types of chlorine sources that water treatment plants can use: chlorine gas, liquid sodium hypochlorite, or onsite production. Chlorine gas can be more cost effective, but a growing number of states are converting to bulk sodium hypochlorite or bleach.20 nov 2018
What chemicals are used in water treatment?
- Algicide.
- Chlorine.
- Chlorine dioxide.
- Muriatic acid.
- Soda ash or Sodium bicarbonate.
Is chlorine still used in drinking water?
Yes. The U.S. Environmental Protection Agency (EPA) limits the amount of chlorine in drinking water to levels that are safe for human consumption. The levels of chlorine used for drinking water disinfection are unlikely to cause long-term health effects.
What form of chlorine is used in water treatment?
The three most common chlorine-containing substances used in water treatment are chlorine gas, sodium hypochlorite, and calcium hypochlorite. The choice of the chlorine type to be used often depends on cost, on the available storage options and on the pH conditions required.
Is chlorine used to treat drinking water?
The U.S. Environmental Protection Agency (EPA) allows drinking water treatment plants to use chloramine and chlorine to disinfect drinking water. Research shows that chloramine and chlorine both have benefits and drawbacks. Chlorine is a highly effective method of disinfection.
What is the difference between chlorine and chloramine?
The major difference between chloramine against chlorine is that chloramine is less volatile — it stays in the water longer, and is less reactive with organic matter (such as disinfection by-products).22 oct 2019
What are the different types of chlorine?
There are 5 types of Chlorine; Sodium hypochlorite, Lithium hypochlorite, Calcium hypochlorite, Dichlor, and Trichlor. The first difference is Sodium, Lithium, and Calcium are un-stabilized Chlorine. Dichlor and Trichlor are stabilized.14 dic 2013
Does high chlorine cause high pH?
Pool Chemicals Granulated or liquid chlorine is alkaline and, therefore, tends to raise the pH level. Bromine is more neutral and has a minimal effect on pH, while chlorine gas is acidic and lowers pH. ... The most common ones are hydrochloric acid, which lowers pH, and soda ash, which raises it.
Is chlorine gas basic or acidic?

Does chlorine dioxide change pH?
Chlorine dioxide (ClO2) is used commercially for bleaching and disinfecting various process waters. ... Chlorine dioxide does not dissociate in water but forms a true solution of gas in water. Therefore, the pH of the water does not affect the efficiency of the application.
