 The importance of water treatment equipment

Brewing water is the most important raw material for beer equipment, and brewing water is called "the blood of beer". The special characteristics of famous beers in the world are determined by their respective brewing water, so the brewing water quality not only determines the quality and flavor of the product, but also directly affects the whole brewing process. Therefore, the correct and reasonable use of brewing water produced by water treatment is of great significance in production.

Equipment processing principles and technologies:

1. Acid addition method:

     Using acid to improve water quality is a simple, convenient and effective method, which is often used in production. Although adding acid cannot change the hardness value of water, it can change the carbonate hardness to non-carbonate hardness, so as to reduce the RA value and improve the water quality.

2. Gypsum or calcium chloride method

Adding gypsum or calcium chloride has a significant effect on changing water quality and reducing RA value. Reasonable use has no effect on beer quality, and the cost is much lower than adding acid. It is a water treatment method widely used in beer production.

3. Reverse osmosis method

The reverse osmosis method can also remove the salt in the water more thoroughly. In addition, the reverse osmosis method can also remove organic matter, bacteria, viruses, etc. in the water. The most commonly used equipment is reverse osmosis water treatment.

Process flow of reverse osmosis water treatment

1. Pretreatment

Carry out pre-treatment on raw water, improve the water quality of water supply, make it meet the requirements, reduce and delay membrane pollution, and prolong its life. Its treatment objects are mainly microorganisms, bacteria, colloids, organic matter, heavy metal ions, solid particles and free Chlorine, etc., to meet the water intake requirements of the reverse osmosis unit and ensure the long-term stable operation of the reverse osmosis unit.

Pretreatment consists of sand filter, carbon filter, water softener and security filter.

Sand filter: filter out the sediment, impurities and suspended solids in the water, and reduce the SDI (pollution index density) value of the raw water.

Carbon filter: It has dual functions, one is adsorption; the other is filtration, which can filter out chemical organic matter, heavy metals, color, peculiar smell, residual chlorine, etc. in tap water, and improve the taste.

Water softener: through sodium-type cation exchange resin exchange treatment, remove calcium, magnesium and other scaling ions in raw water, and remove the hardness of raw water.

Security filter: 5μm PPF (polypropylene fiber filter element) filter element, which intercepts objects larger than 5μm and prolongs the life of the membrane.

4. Reverse osmosis device

The separation pore size of the membrane is 10-7~10-6cm, which can remove organic matter, heat source, virus and other substances in the water. After the fluid has been pretreated in the first three stages, the water after the deep separation treatment of the reverse osmosis RO membrane host makes it beneficial to human health. The water that is not conducive to human health is discharged, the desalination rate is 98%, and the pure water produced enters the pure water tank. A good system design can ensure that the whole system does not need to replace the membrane elements within three years (the service life is related to the water quality of the water source); the online conductivity display can dynamically display the water quality status of the water purification production at any time. The high-pressure pump provides the working pressure of the permeated water of the membrane to maintain the water production rate, and it is divided into one or two high-pressure pumps for pressurized permeation treatment.

5. Control function description

This system changes the corresponding output signals of the water inlet valve, high pressure pump, flushing valve and other actuators according to the changes of input signals such as high pressure, low pressure, liquid level, reset, switch, etc., so as to achieve a standard RO system of automatic control and realize pressure protection. , liquid level control, power on/full water/automatic flushing and other functions.
