Application of reverse osmosis pure water in winemaking process

Nowadays, the winemaking process is constantly innovating, the production capacity of the best wine is constantly expanding, and the consumption level of wine is rising, and the quality of wine has become the most basic factor affecting the growth of market sales. The consensus of tasters. Speak with wine quality, let consumers taste consumption with wine quality, and improve wine quality has become the full action of wine merchants. There are many ways to improve wine quality, but water is the most basic and critical element.

As the saying goes, one side of water makes another side of wine, all ethnic groups and regions in the country have their own local wine tastes, and preserving and improving the wines that represent the region is the main axis of developing local famous wine brands. Scientific development, technological progress, the replacement of craftsmanship, and the improvement of taste habits continue to show the influence of wine craftsmanship on wine quality. Wine merchants and wine tasters often encounter the effects of water on wine.

Turbidity

The wine itself is a colloidal solution. If there are no other substances, the wine itself has excellent stability, without any suspended solids and impurities precipitation, and the wine is clear and transparent. When the alcohols and acid radicals in the wine are intertwined with the metal ions in the water, the positive and negative charges will be neutralized, the colloid will dissolve, the particulate matter will appear, and the wine will appear turbid. This turbidity is caused by the presence of metal ions and mineral ions in the water.

Salty taste

It is mainly due to the high hardness of the water, carrying metal salts such as sodium, and making wine without treatment, which can cause the wine to have a salty taste, or in the currently commonly used water treatment process equipment, the residual sodium is mixed with water due to operational errors The process also causes the wine to be salty.

Fishy smell

also known as iron smell and rust smell, the reason is that the content of iron, manganese, tin and other metal ions in the water exceeds the standard, especially in the northern region, most of the drinking water comes from well water, and the iron and manganese content of well water in the northern region exceeds the standard. Untreated or incompletely treated, the water looks clear and transparent, but the iron and manganese content in the water is still high, which will affect the taste of the wine.

Bitterness

Also known as bitterness, the bitterness of water quality in wine production is generally due to high alkalinity, high temporary hardness, and high content of sulfates and other substances in the water. Such water is not treated or the operation of water treatment equipment occurs. Mistakes will directly aggravate the taste of wine.

Others, due to the influence of water on wine quality, will not be elaborated. This article will mainly introduce the new water treatment technology in the brewing process in detail.

In the wine making process, the commonly used technologies for water treatment include softening, ion exchange, electrodialysis, ultrafiltration and other processes. However, because the water treatment operators are not professionals after all, they often do not grasp the amount of treatment in use. In addition, the equipment management is not strict, and the wine quality will be different in batches. In addition, various water treatment methods have their own advantages and disadvantages. It is impossible to treat all the water content, and it is impossible to fundamentally improve the quality of drinking water. In view of the problems that have occurred in the above technologies over the years, this paper introduces a new process water treatment technology, reverse osmosis membrane water treatment equipment

The reverse osmosis process technology is a water treatment technology using membrane separation. With the advancement of membrane scientific research and manufacturing technology, reverse osmosis water treatment technology has developed rapidly. Reverse osmosis water treatment technology is basically a physical method. It uses physical and chemical processes to have many advantages that traditional water treatment methods do not have:

  • Reverse osmosis is to desalinate and purify water at room temperature by using a physical method without phase change.
  • Water treatment relies solely on pressure as a driving force, and its energy consumption is the lowest among many treatment methods.
  • No need for a lot of chemical agents and acid and alkali regeneration treatment
  • No chemical waste liquid and waste acid and alkali discharge, no neutralization process of waste acid and alkali, and no environmental pollution.
  • The system is simple, the operation is convenient, the water quality of the product is stable, and high pure water can be obtained.
  • It is suitable for a wide range of raw water quality, not only for the treatment of brackish water, seawater and sewage, but also for the treatment of fresh water with low salt content.
  • The equipment occupies a small area and requires less space.
  • Extremely low operating maintenance and equipment repairs.
  • Reverse osmosis has obvious advantages in many pure water use departments, and has excellent characteristics that are incomparable with conventional ion exchange treatment methods, such as: the effect of removing silica from water is good, and the removal rate can reach 99.5%, avoiding natural The influence of silicon in water on the difficulty of regeneration and short operation period of ion exchange resin.
  • Remove organic and colloidal substances from water, and the removal rate can reach 95%.
  • The reverse osmosis water treatment system can continuously produce water, and stop regeneration and other operations during no operation.
