I drink straight from the pipe. Do you understand?

The raw water of direct drinking water is deeply purified by multi-media, activated carbon, security filter, membrane shell, nanofiltration membrane and other processes, and then transmitted to each household through food grade stainless steel pipes. Compared with barreled drinking water, "pipe direct drinking water" is a circulating and filtered "living water", which is safer and better in quality.

So, how does such a good direct drinking water come from? Here is a 2-minute popular science!

1. Raw water tank and pump

This is the first step in the pipeline direct drinking water service process. The raw water tank mainly serves as a buffer. Considering that there may be uncertainties such as planned water cut-off in the raw water, in order to affect the follow-up water purification equipment itself and the treatment effect, a water tank is set up in the first step to regulate and buffer the raw water. The raw water pump pressurizes the raw water and sends it to the water purification equipment that needs a certain pressure to be filtered. At the same time, it ensures that the "pipeline direct drinking water" is the "living water" of circulating flow and circulating filtration from the starting point.

2. Various filters

The raw water of direct drinking water is further purified by multi-media, activated carbon, security filter and other processes to ensure better water quality.

3. Membrane treatment system

The system is the core part of direct drinking water treatment. Considering the long-term drinking health needs of users, Changsha shuisiyuan selects the core process of the new city guanshanyin pipeline direct drinking water project as the (NF) nanofiltration membrane technology with a filtration accuracy of 0.001 μ M.

One of its characteristics is that the membrane body is charged and mainly removes solute particles with a diameter of about 1 nm. Therefore, it is called "nanofiltration membrane", which can retain calcium, magnesium and trace elements required by the human body.

4. Clean water tank

Finally, the water purified by the precision equipment comes to the clean water tank. In addition to the water storage, the clean water tank is equipped with a double guarantee - ozone and ultraviolet disinfection. They are the guarantee of the safety and health of direct drinking water. Ozone can destroy the biofilm structure by oxidation to achieve sterilization. Ultraviolet is a kind of electromagnetic wave. With this layer of protection, we can ensure that the water delivered to the residents' homes through food grade stainless steel pipes is high-quality direct drinking water!
