How to ensure the safety of drinking water quality after flood disasters ?
Summer is a season prone to flood disasters. After the flood disaster, the safety of drinking water is the most concerned issue for people.
In order to ensure that drinking water meets the safety use indicators, what needs to be tested and how to test it?
First, we need to observe the color and smell the smell. If the color is turbid and there is a clear odor, then it is definitely not a safe water source.
Then, excluding what the eyes see and the nose smells, it is necessary to use professional instruments for other indexes testing.
The instruments needed are as follows:
| Detection Indicator | Recommend product Model | Guideline |
| pH | PH310F / PH310T /PH300F / PH400F | Drink water standard pH value should be 6.5~8.5. |
| Conductivity / TDS | EC310T / EC510T / EC300F /EC400F | The conductivity limit of drinking water standards is no more than 2000us/cm, The TDS value (total dissolved solids) is no more than 1000ppm. |
| DO | DO210E/DO310F/DO510T | The standard range of drinking water dissolved oxygen should be 5~8mg/L |
| Total Harness | Bante322 / Bante932 / A131 | The standard range of drinking water hardness should not exceed 450 mg/L. It is generally believed that water with a hardness between 50mg/L and 200mg/L is safer and healthier. |
| Color | SD9011AB/SD9012AB | In addition to observation with the eyes, it can also be accurately measured with the help of instruments. The standard range of drinking water color is no more than 15 degrees |
| Turbidity | TU200P/TU1000P/WGZ-500B | In addition to observation with the eyes, it can also be accurately measured with the help of instruments. The standard range of drinking water turbidity is no more than 1 NTU. To further ensure water quality, the turbidity internal control index value can be set at 0.3 NTU or even lower. |
| Chloride | DGB | The standard range for chloride in drinking water is 250 mg/L |
| COD | COD-100 | The standard range of COD in drinking water is 15 mg/l |
| Fluoride | I300F /I400F | The standard range of Fluoride in drinking water should be 0.5~1.0mg/L |
| Total organic carbon | TA100 / TA200 | The level of TOC in drinking water should be less than 2.0mg/L |
| Microorganism | JC600 | Used for multiple tests such as total colony count, total coliform count, fecal coliform, Escherichia coli, etc. |
