Disinfection is one of the vital steps in any water treatment procedure before the water gets into end-use or for consumption. There are three chief methods to disinfect water and they are: a) Chlorination b) UV c) Ozonation for water wastewater treatment industries. The chlorine dosing system is suitable for industrial water treatment plants. To some extent, the UV system is used in water & wastewater treatment plants and Ozonation for domestic and potable water treatment. Every disinfection process has its peculiarity but all those processes aim to eliminate organic content or bacteria in the treated water. Most people prefer hypo chlorine dosing systems.

What is chlorination?

Raw water from streams, lakes, rivers & groundwater contains microorganisms though not every microorganism is harmful to our human health but some of them can cause diseases. Those are known as pathogens. The pathogens in water transmit through the distribution system of drinking water that causes water-borne diseases. For combating such waterborne diseases, disinfection methods are vital for inactivating those pathogens. Chlorination makes water safe for human consumption usage. Chlorination is the most prefered process which was first used a century ago. The chlorination process is the chemical disinfection process that uses several kinds of chlorine or chlorine consisting substances for disinfection.

Why do we require chlorinating water?

According to several studies and researches for ensuring success in the latest water treatment plants by using chlorine as the disinfectant. Why do most water treatment plants use this process of chlorination? The answer is – It has been proved as effective and efficient against viruses & bacteria. Chromination is a good disinfection process to use as it is not costly yet effective. As compared to any other water treatment process, the chlorination method is quite hassle-free to maintain. Chlorination also helps in eliminating an overload of pathogens quickly. You can install a hypo chlorine dosing system for disinfecting water.

How can chlorination inactivate microorganisms?

The method of chlorination damages the cell membrane of the microorganism and thus inactivates them. When once the membrane gets weakened, chlorine enters quickly into the cell & disrupts its respiration & its DNA activity (Both processes are important for cell survival).

When can chlorination be done?

You can do chlorination at any point of time in your water treatment plant as there is not only a particular time to add chlorine. The chlorine application is a full spectrum of treatment.

In the pre-chlorination stage, chlorine is added to water immediately after entering the water treatment facility. In this step, chlorine is added to raw water directly. Chrome is usually added in this stage for eliminating algae so that they can not cause issues in the later stages of treatment.

The chlorination method can also be done as the last step in the water treatment method that is normally done in most water treatment plants. The main aim of adding chlorine is to disinfect water & maintain residuals of chlorine.

Does chlorination water harm human beings?

The chlorination process such as hypo chlorine dosing systems is not harmful. The concentration of chlorine in drinking water is very low and therefore not at all a big concern.

What is the field effectiveness of chlorination?

Not only in industrial water treatment plants, but the chlorination method is suitable for household water treatment programs too as this is considered to be one of the most effective processes to inactivate most viruses and bacteria. In many developing countries, many studies show full elimination of bacterial pathogens.

What are the different types of chlorination methods?

There are different kinds of chlorination methods. The below-mentioned processes vary in the chlorine amount used. Lets us have a glance at those:

a) Batch disinfection

b) Simple chlorination

c) Super chlorination

d) Shock chlorination

e) Dechlorination

What are the benefits of chlorination?

There are numerous benefits of chlorination and they are:

a) Through chlorination almost every harmful virus and bacteria get eliminated and it becomes suitable for water consumption.

b) Chlorination process not only just clean water but also offers protection from recontamination and this ensures approval for drinking water testing.

c) In a large area, chlorine is quite affordable for disinfecting water

d) Low in cost and has great scalability.

We hope after reading this blog you have understood why chlorination is best for disinfecting water. The chlorine dosing system like hypo chlorine dosing systems is quite effective in water disinfection. Chlorination has always been a famous method in effectively removing bacteria & viruses except for some protozoan cysts.
