Drinking Water Treatment

As a result of rapid population growth and industrial activities all over the world, there have been serious decreases in water resources. The protection of existing water resources, the treatment of poor quality water taken from the source for use and drinking purposes have gained importance in recent years. The importance of preparing water of appropriate quality for various uses has increased.

The heavy metals in raw water are stabilized and flocculated with chemical treatment processes such as coagulation, neutralization and flocculation, and then removed from the water by precipitation in chemical sedimentation units. The amount of suspended solids in raw water is also reduced with chemical treatment processes. After chemical treatment, raw water can be treated with advanced treatment technologies such as membrane bioreactors, ion exchange, reverse osmosis, advanced filtration, active carbon filters, disinfection, electrodialysis, oxidation methods and can be used for domestic, urban and agricultural purposes, as well as as process water in industries.

The sediments caused by suspended solids, particles, dust, and mud that may be present in water cause turbidity in water and create a favorable environment for microorganism growth. When choosing a purification method, the quality of the water must be determined first. These are color, turbidity, odor, temperature, pH level, and pathogenic microorganisms in the water. In purifying drinking water, the aim is to ensure the physical and aesthetic quality of the water (obtaining colorless, odorless, tasteless, and clear water), to remove harmful and toxic substances from the water, and to remove disease-causing microorganisms from the water.
