Brewing water is the most important raw material for beer equipment, so brewing water is also called “the blood of beer”. The particularity of the world-famous beer is determined by the 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 rational use of brewing water produced by water treatment is of great significance in production.
Equipment Processing Theory And Technologies
Acid Addition Method
Using acid to improve water quality is a simple, convenient and effective method that is often used in production. Although the addition of acid cannot change the hardness value of water, it can change the hardness of carbonate to non-carbonate hardness, so as to reduce the RA value and improve the water quality.
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.
Reverse Osmosis Method
The reverse osmosis method can 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. And reverse osmosis water treatment is a more common water treatment method in equipment.
Process Flow Of Reverse Osmosis Water Treatment
Carry out preliminary treatment of raw water to improve the quality of water supply to meet the requirements, reduce and delay membrane pollution. To prolong its life, its treatment objects are mainly microorganisms, bacteria, colloids, organic matter, heavy metal ions, solid particles and free chlorine, etc., which enter the water, so as to meet the requirements of the reverse osmosis device’s water intake and ensure the long-term stability of the reverse osmosis device run.
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, adsorption and 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.
Ecurity filter: 5μm PPF (polypropylene fiber filter element) filter element, which intercepts objects larger than 5μm and prolongs the life of the membrane.
（2）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. The water after the fluid has been pretreated in the first three stages is subjected to deep separation treatment by the reverse osmosis RO membrane main engine, so that it is beneficial to human health. A good system design can ensure that the entire 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.
（3）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.
