Who can tell me the difference and propaganda words between pure water, single-stage reverse osmosis water and double-stage reverse osmosis water?

First, the premise of single-stage and double-stage pure water is that it can reach the index of pure water, such as the conductivity is less than10 us/cm;

Secondly, for the same area or the same water source, using two-stage water production has smaller conductivity, especially when the raw water quality becomes worse and the desalination rate of reverse osmosis decreases, the water quality is more secure;

Third, different raw water quality, the water quality of Grade I and Grade II is sometimes slightly different, and most of the water quality of Grade II tastes better;

4. Slogans: such as "two-stage reverse osmosis double guarantee" and "two-stage reverse osmosis is sweeter and better".

Verb (abbreviation of verb) Other suggestions: It is nothing new to do pure water double-stage reverse osmosis; If you want to do a good job in the market, a good water source is essential, and the water it produces can be sweet and delicious; In addition, market operations, publicity, sales, applications, etc. Are important.

I hope it works!

thank you
