  • Boiling. Bring the water to a rolling boil for 3-5 minutes. Let cool before drinking.
  • Disinfect. You can use household liquid bleach (regular household bleach contains 5.25% sodium hypochlorite) to kill microorganisms.
  • Distillation. Fill a pot halfway with water.

What are purification techniques of water?

There are several methods used in the water purification process, which include: (1) physical processes, such as filtration, sedimentation, or distillation; (2) biological processes, such as sand filters, active carbon; (3) chemical processes, such as flocculation, chlorination, the use of ultraviolet light.

What are the 5 steps of water purification?

Public water systems often use a series of water treatment steps that include coagulation, flocculation, sedimentation, filtration, and disinfection.

What is TDS water purifier?

TDS stands for Total Dissolved Solids and refers to the total concentration of dissolved substances in drinking water.

What is TDS value?

Total dissolved solids (TDS) is measured as a volume of water with the unit milligrams per liter (mg/L), otherwise known as parts per million (ppm). According to the EPA secondary drinking water regulations, 500 ppm is the recommended maximum amount of TDS for your drinking water.

How many types of purification are there?

There are twenty-five methods to purify water, divided into four categories: separation, filtration, chemicals, oxydation. There are five types of contaminants that are found in water: particulates, bacteria, minerals, chemicals, and pharmaceuticals.

What is filtration PDF?

It is a solid-liquid separation process in which the liquid passes through a porous medium to remove as much fine suspended solids as possible. Applications: • In water treatment plants, a polishing. step to remove small flocs and other.

What is the pH of RO water?

between 6 and 7
RO water has a pH between 6 and 7, but no matter what the pH of the water you consume, as it passes through the cell wall, it instantly becomes the pH of your body. – Water is not a significant source of minerals and the pH of the water makes no difference.

What is difference between RO and UV?

UV filter kills all the pathogens present in the water. However, the dead bacteria remain suspended in the water. On the other hand, a RO water purifier kills the bacteria and filters out their dead bodies floating in the water. Hence, RO purified water is more hygienic.
