What Goes On In A Water Treatment Plant
Unlike desalination, water treatment is done on an industrial basis where there is a need to supply large quantities of water usually for commercial purposes. Water treatment ensures that:
- All impurities are removed from the water so it can be used for medicinal, industrial and drinking purposes.
- It mainly helps get rid of bacteria, fungi, and viruses and certain chemical pollutants like fertilizers.
Processes Involved For Industrial Water Treatment
These are the basic guidelines provided on industrial water treatment by the World Health Organization and most treatment plants stick to it when processing drinking water.
- Storage and Sedimentation
The quality of water is greatly improved during the storing and sedimentation process. The water is stored and all the particles which are insoluble in water start sinking into the bottom of the storage tank. Sometimes for particles which do not settle within the regulated forty eight hours, certain chemicals are added to allow coagulation of those particles.
The reservoirs are often flushed to be cleaned thoroughly so that the quality of water for purification remains unaffected.
The water is pre treated by roughing filters to get rid of insoluble particles. The roughing filters help get rid of certain pathogens in the water as well. The filters are normally cleaned out every month to ensure that the filters do not become clogged. In case of clogging the water treatment may be affected and rendered unhygienic. A yearly removal of filters is carried out as well to be cleaned or replaced.
- Slow Sand Filtration
The water is passed from a bed of sand wherein most of the impurities settle down. The top of the filter contains certain microorganisms which feed on the bacteria and viruses. The unfiltered water enters from an inlet and after being purified is emptied into a clean water main.
One of the most common chemical way of treating water, chlorination works by rendering the pathogens to become inactive. Most water treatment plants employ a flow chlorinator which keeps releasing a weak solution of chlorine on a continuous basis to keep water purified. However the only drawback of chlorination system is that it doesn’t work too well with water with a ph of 8 or more. Similarly if the water contains too many microbe or organisms it still needs to be pre-treated before being chlorinated.
Benefits of Water Treatment Services
The following are some benefits of water treatment services that are offered by the companies that specialise in this area.
- Treated water is drinkable. It retains the taste of natural water which is sparkling clean and appealing to drink as well.
- Hard water can damage the plumbing system by slowly eroding the pipes. With treated water you can rest assured that your plumbing system stays in top shape year after year.
- Cleaner bathrooms and tiles. There is considerably less grime on floors where water isn’t hard or contains a great deal of salt. Tiles can be cleaned quicker.
- Clothes are brighter and look newer than ever. You can see the difference once you start washing your clothes with softened water.
- That’s not all treated water is useful for industrial purposes as well and can be used in abundance in making of medicines.
