Water leaving purification plant contains very small amount of microbes, and as such requires no additives to be drinkable. The problem arises between water treatment plant and end consumer: all those pipes will inevitably have microbes of different kinds (bacteria like Escherichia coli, fungal forms etc.). Small levels of chlorine slows the growth of bacteria in water, and helps prevent water-borne diseases.
What else can I help you with?
What is the reaction between chlorine and water?
Chlorine reacts with water to form hydrochloric acid (HCl) and hypochlorous acid (HClO). This reaction is important in water treatment processes, where chlorine is used as a disinfectant to kill bacteria and other harmful microorganisms in water supplies.
What procedure is used to determine the level of combined chlorine in water?
The level of combined chlorine in water is typically determined using a test kit that measures the total chlorine and free chlorine levels. By subtracting the free chlorine level from the total chlorine level, the level of combined chlorine can be calculated. This measurement is important in determining the effectiveness of water treatment processes.
What do you mean by residual chlorine?
Residual chlorine refers to the amount of chlorine that remains in water after it has been treated. It is important for maintaining water quality by ensuring that harmful pathogens are destroyed and that the water remains safe for consumption. Monitoring residual chlorine levels is a common practice in water treatment facilities to ensure that water is properly disinfected.
Why is it important that chlorine and fluoride are added at the end rather than at the beginning of the water treatment process?
Adding chlorine and fluoride at the end of the water treatment process ensures that they are present at the correct concentrations in the finished water. If added at the beginning, there is a risk of them being degraded or reacting with other chemicals during the treatment process, leading to ineffective disinfection or fluoridation of the water.
How chlorine is used in treatment of public water supply?
Chlorine is used in the treatment of public water supply to kill harmful bacteria and microorganisms. It is added to the water at the treatment plant in carefully controlled amounts to disinfect the water and make it safe for consumption. Chlorine helps to prevent the spread of waterborne diseases and ensures that the water meets safety standards.

Chlorine is used to kill bacteria in the water at treatment plants. This chlorine can be harmful to some aquatic species. Based on this information what other step must be taken in the treatment of w?
After using chlorine to kill bacteria in water treatment plants, an important step to ensure the protection of aquatic species is to dechlorinate the water before it is released back into the environment. Dechlorination helps to neutralize the harmful effects of chlorine on aquatic life, ensuring the ecosystem's health is maintained.

What one following is not a step in the three-step water treatment process?
The step of monitoring water usage is not typically a part of the three-step water treatment process. The common steps are preliminary treatment, primary treatment, and secondary treatment. Monitoring water usage is important for conservation and efficiency but is usually a separate process from treatment.
Why does my water taste like chlorine?
The taste of chlorine in your water is likely due to the presence of chlorine used in the water treatment process to kill bacteria and other harmful organisms.
Does chlorine dissolve in water easily?
Yes, chlorine dissolves easily in water, forming a solution known as chlorine water. This solution is commonly used for disinfection and water treatment purposes.
How can chlorine enter fresh water sources?
Chlorine can enter fresh water sources through discharges from industrial activities, wastewater treatment plants, and agricultural runoff. It can also enter water sources through the use of chlorine-based disinfectants in water treatment processes.
Does chlorine pollute water?
Chlorine can be a water pollutant when it reacts with organic compounds in water to form disinfection byproducts that can be harmful to human health. However, chlorine is also commonly used to disinfect water in treatment plants to make it safe for drinking. It is important to carefully regulate the level of chlorine in water to balance its disinfection properties with potential pollutants.
Chlorine is used to kill bacteria in the water at water treatment plants. This chlorine can be harmful to some ocean species. Based on this information what other step must be taken in the treatment o?
To mitigate the harmful effects of chlorine on ocean species, water treatment plants can implement additional steps such as dechlorination processes to remove residual chlorine before discharging treated water into the ocean. This can help protect marine life from the negative impacts of chlorine exposure.
