The fermentation of microorganisms can produce beverages with a certain alcohol concentration. The three main factors in the process of brewing are the brewing materials, brewing process, and brewing raw water. The types of wine are divided into grape wine, yellow wine, rice wine, Wujiapi wine, beer, foreign wine, etc. The raw materials and brewing process used for each type of wine are different, and the pure water used is the same. However, if the water quality of the pure water does not meet the requirements, it will directly affect the taste and quality of the wine.

A complete set of water treatment equipment consists of a pretreatment system, RO reverse osmosis technology, pure water tank, and ozone sterilization system.
The water treatment process for producing pure water in the brewing industry includes: raw water (tap water or groundwater) - raw water mercury - multi-media filter - activated carbon filter - water softener - regenerated salt tank - security filter - high-pressure pump - reverse osmosis - cleaning medicine tank - precision filter - ozone generator - pure water tank (water target).
 
The produced pure water will change in electrical resistivity with the change of storage time, so the size of the equipment should be customized according to the hourly water consumption. The scale of the equipment is small at 0.25T/H, while large equipment can reach thousands of tons per hour.
 
The entire equipment mainly adopts reverse osmosis technology. The principle of reverse osmosis refers to the selective permeation of water molecules through the membrane under the pressure of liquid pressure. Impurities that cannot pass through the membrane will be trapped on the other side of the membrane, and pure water will be retained in the next treatment system to achieve water purification.
