Instruction for use of Utility calculator for chlorine dosing for disinfection

What is water chlorination and how does it work?

Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria and viruses. Various processes can be used to achieve safe chlorine levels in drinking water. Using or drinking water with small amounts of chlorine does not cause harmful health effects and helps protect against waterborne disease outbreaks.

Chlorine is one of many methods that can be used to disinfect water. This method was first used more than a century ago, and is still used today. This is a chemical disinfection method that uses a variety of chlorine or chlorine-containing substances to oxidize and disinfect potable water sources.

Enter the input value

Step 1: Enter input water flow to be treated, unit is m3/h. For example, choose 10m3/h

Step 2: Enter the dose of chlorine that needs to be added to the water, the unit is mg/l, g/m3 or ppm, etc. For example, enter 3 mg/l

This index depends greatly on the amount of input water and the required residual chlorine content after filling. The most common is to choose 2-4mg/l for water supply, 7-10mg/l for wastewater or possibly higher.

Step 3: Enter the initial chlorine concentration, in %. Choose 10% as Javel water

For example, when buying powdered chlorine, the box will have parameters about the chlorine concentration. If it says 70%, you fill in the number 70.

Step 4: Enter operating time, unit h/day. Select 24h

This is the time the water treatment system operates in 1 day, which can be 6, 10, 15, 20, 24 hours/day

Step 5: Enter the chemical mixing cycle, day unit. Select 7 days

This is the cycle time you need to mix the chemical once, for example if you want to mix it once every 10 days, choose 10

Step 6: Enter the volume of chemical mixing tank, unit L. Select 500L tank

This is the volume of the chemical mixing tank, commonly 100L, 200L, 300L, 500L, 1000L, etc.
