Study Notes
Drinking Water Treatment
- Drinking water sources require treatment before distribution because they may contain harmful substances, pathogens, and other contaminants that can affect human health.
Removal of Dissolved Minerals
- Ion exchange is generally used to remove dissolved minerals like hardness components (calcium and magnesium) and iron and manganese from drinking water.
Natural Water Composition
- Natural waters are likely to contain dissolved substances, suspended particles, and microorganisms, which can affect their taste, odor, and quality.
Removal of Dissolved Substances
- Reverse osmosis is a unit process that is generally used for the removal of dissolved substances in water.
Increasing Need for Treatment
- The increasing need for treatment of drinking water sources is contributed by factors such as population growth, urbanization, and climate change, which can lead to contamination of water sources and affect the quality of drinking water.
