Define conversational water treatment, and explain any two treatment unit be involved in convectional Water treatment and include purpose for each?

Conventional water treatment refers to the process of treating water to make it safe for consumption and other uses through a series of physical, chemical, and biological processes. This type of treatment is commonly used in municipal water treatment plants and other large-scale facilities.

Two treatment units commonly involved in conventional water treatment are:

1. Coagulation and Flocculation: Coagulation is the process of adding chemicals such as alum or ferric chloride to water to destabilize suspended particles and colloids. This causes the particles to clump together, forming larger particles called floc. Flocculation involves gently mixing the water to encourage the floc to come together and settle out of the water. The purpose of coagulation and flocculation is to remove suspended solids, turbidity, and other impurities from the water, making it clearer and safer to drink.

2. Filtration: After coagulation and flocculation, the water passes through a filtration system to remove any remaining particles, bacteria, and other contaminants. Filtration can be done using various materials such as sand, activated carbon, or membranes. The purpose of filtration is to further purify the water and improve its clarity and taste. It also helps remove any pathogens that may be present in the water, making it safe for consumption.

Overall, conventional water treatment involves a combination of processes to ensure that water is safe, clean, and free from harmful contaminants before it is distributed for use.
