How to disinfect groundwater by drinking water treatment method?

In the process of groundwater treatment, ultraviolet disinfection is a good choice in terms of effect.

After groundwater collection, suspended solids, colloidal substances and pathogenic microorganisms in the water should be removed by conventional treatment. The main technologies used are coagulation, sedimentation, filtration and disinfection.

There is specialization in the industry, leaving aside other technologies and processes. Just talk about the disinfection method in the process of groundwater treatment-ultraviolet disinfection. Of course, ultraviolet disinfection is not the only choice, but from the perspective of economy and effect, ultraviolet is a very suitable disinfection method in groundwater treatment.

General groundwater treatment process:

Groundwater → quartz sand filter → activated carbon filter (softener) → ultraviolet sterilization and disinfection system → drinking water tank.

Ultraviolet disinfection technology has been widely used in the disinfection of groundwater treatment, and the technology is very mature.

Advantages of ultraviolet disinfection: no chemicals are put in, the odor of water is not increased, toxic and harmful by-products are not produced, the disinfection speed is fast, the efficiency is high, and the equipment operation is safer, simpler and more automatic than the traditional disinfection process.

Disadvantages: UV disinfection effect is greatly affected by water quality, especially suspended matter and turbidity. When water permeability is poor, disinfection effect will be affected. However, due to the installation of ultraviolet disinfection equipment at the end of the whole treatment process, the light transmittance of water quality is guaranteed.

Then let's take a look at the germicidal efficacy of ultraviolet rays.

As can be seen from the above table, ultraviolet rays are very destructive to most bacteria and viruses, which can completely meet the requirements of sterilization and disinfection of groundwater. Because no chemicals are added, it is easier to pass and accept the residual chlorine test.

So, what is the cost of the ultraviolet sterilizer? The general dosing equipment on the market is 10 thousand yuan.

But ultraviolet equipment is different. Compared with other equipment, the production requirements of ultraviolet light are lower and the price is more advantageous.
