Before you gulp your water, try to imagine how that water got from that raindrop to the clear, odorless water that you now see in your glass: how did it get from there to here? Lakes, rivers, and groundwater supply us with drinking water. A water supply usually passes through an intake point, a treatment plant, and a storage tank before being delivered to our houses by a combination of pipes.
To eliminate disease-causing agents from drinking water sources, water must be properly treated in a water treatment plant. To provide safe drinking water to their communities, public water systems use a variety of water treatment methods. Most water systems today use these methods of water treatment (mainly surface water treatment):
Water Treatment with Zero Liquid Discharge (ZLDWT)
Any drop of water is not permitted to discharge in zero liquid discharge. Approximately 98% of water is recovered in ZLD plants. The latest technologies have been incorporated and the best results have been achieved. ZLDW may be a great solution for the environment and is a great way to treat liquid waste from the water.
ETP (Effluent Treatment Plant)
An EPTP method purifies industrial wastewater so that it can be reused or disposed of. Based on the industry, different types of effluent contain different materials. Oil and grease can be found in some effluents, as well as toxic materials.
STP (Sewage Treatment Plant)
The sewage treatment process is used to remove contaminants from domestic and municipal wastewater, primarily household sewage, as well as some industrial wastewater. STP plants treat household sewage to remove contaminants, micro-organisms, and other pollutants.
Treatment of domestic water
A household water supply or drinking water should be completely safe and free of any harmful effects on consumers; it should be palatable to the tongue, free of odor, color, and turbidity, and should contain allowed levels of dissolved solids, such as calcium magnesium sodium, their bicarbonates, chlorides, and sulphates.
Automated Screening System
For all applications that require fine screening, this section makes up the head of the wastewater treatment plant. By doing so, all coarse materials that are present in wastewater are eliminated, as if they were not removed properly, they would cause obstructions in water treatment machines in the future. Perforated screens are cleaned by brushes that are rotated slowly.
These are just a few mentioned, rest there are many more methods used for the purification of water.
