Due to the types of pollutants and water volume for purification, water quality and consumption, there are three physical, biological and chemical methods for purification.
The physical method of water treatment
In the physical method, water sediments settle and filtration is done by reverse osmosis and ultrafiltration and carbon, sand, nano and micro filters. After removing solid and suspended substances, pathogens are removed using ultraviolet rays.
In the biological method, it will be eliminated by sand filters and activated carbon materials.
Water treatment
In the chemical method, the stages of chemical oxidation, coagulation and disinfection are done with chlorine.
Osmosis means the passage of water from a low concentration to a high concentration. In water purification, osmotic pressure is used to remove water pollutants and produce clear water. Reverse osmosis is one of the most common water filtration methods. In reverse osmosis, a membrane filter is used to produce healthy drinking water.
Reverse osmosis The best way to remove water pollutants
The method of ultrafiltration in the treatment plants around the city is reverse osmosis pre-treatment. It completely removes all suspended particles, pathogenic agents, dyes and pharmaceutical industry waste.
Ultrafiltration under the influence of pressure difference
The water passes through the membrane filter under pressure and gets impurities, and after disinfection and clarification, it enters the city water tank as drinking water. Long life of membranes in reverse osmosis method, performance and high speed of resistance to pollution are the advantages of ultrafiltration.
کاربرد دستگاه تصفیه آب خانگی
The best home water purifier removes all pollutants and toxic and harmful substances from water. Rain water enters the underground water and the most important of them are calcium and magnesium. When there are large amounts of mineral salts, metals and ions in water, it causes water hardness and problems for humans. Sediment in the samovar, kettle and bathroom pipes causes the pipes to be blocked. Soap and detergents do not lather well in hard water.
The salty taste of water is due to mineral salts in hard water, which causes kidney stones. Boiling, chlorine and water purifiers are used to reduce water hardness. The reverse osmosis filter is suitable for removing harmful substances from water and removing water hardness.
The complications of oral water chlorine
✅ Skin allergies
✅Brain and nerve problems
✅Hair loss
✅Hair whitening
✅ Premature aging
The chlorination process is one of the most common water disinfection methods in the world today.
The most important advantages of this process are:
Chlorination is a cheap and low-cost process for disinfecting water consumed by humans.
Chlorine has a residual effect in water, which ensures the relative health of water. Water is supplied all along the network.
