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.
Instructions for using the utility to calculate the dosage of chlorine disinfectant chemicals with images
Utility interface:
Input
| Enter water flowrate | m3/h | |
| Dose of chlorine (Normally from 1-10mg/l based on water quality) |
mg/l (g/m3) | |
| Chlorine concentrate (Javel 9-10%, Chlorine powder 65-70%, Pure chlorine 99%) |
% | |
| Operation time | h/day | |
| Chemical mixing cycle | Day/time | |
| Chemical storage tank | L |
Results
| Chlorine consumption per hour | 0 | g/h |
| Chlorine consumption per day | 0 | kg/day |
| Antiscalant chemical need to fill in the mixing tank | 0 | Kg |
| Antiscalant chemical concentration after mixed (Recommend concentration less than 5%) |
0 | % |
| Dose of chlorine after mixed | 0 | L/h |
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.
Example data entry according to the following table
Below is the column that returns the results
Chlorine chemical flow to be dosed: 2.68 liters/h, this is the flow you set for the metering pump to fill the water
