Second, the process design of pure water equipment for dairy products
1, the use of a reverse osmosis process, the preparation of food and beverage production process water The process is as follows:
raw water tank → booster pump → multi-media filter → activated carbon filter → security filter → high-pressure pump → a reverse osmosis → pure water tank

2, the use of two-stage reverse osmosis process, the preparation of pure water The process is as follows:
raw water tank → booster pump → multi-media filter → activated carbon filter → security filter → high-pressure pump → a reverse osmosis → high-pressure pump → two reverse osmosis → pure water tank → ozone sterilization → finished product tank → water pump → microporous filter → filling

3, the use of ultrafiltration / nanofiltration process, the preparation of mineral water The process is as follows:
raw water tank → booster pump → multi-media filter → activated carbon filter → booster pump → an ultrafiltration → intermediate tank → ozone sterilization → finished water tank → booster pump → porous filter → filling


Three, dairy products with pure water equipment process flow description

1. Automatic sand filter:
Automatic sand filter is composed of automatic control valve, glass fiber reinforced plastic tank and quartz sand with different grade ratio. It can effectively remove suspended solids and some colloidal substances in the raw water and reduce the turbidity of the raw water. And can automatically backwash. Because tap water contains a certain amount of impurities, such as sediment, rust, red worms, organic matter, microorganisms, mechanical impurities and so on. The presence of these impurities seriously affects the water quality and treatment of refined water, through the quartz sand pretreatment after the water turbidity, color, colloidal matter, organic matter, iron, manganese, microorganisms, volatile substances, dissolved gases and other impurities removed or reduced to a certain level.

2. Full-automatic activated carbon filter:
activated carbon filter is composed of full-automatic control valve, high-quality glass tank and different water purification grade activated carbon. It can effectively adsorb heavy metals, free chlorine, chloroform and other harmful substances in the raw water. And it can be backwashed automatically. Sterilization of tap water is usually chlorine in the water, in order to maintain the effect of killing bacteria in the pipe network should always maintain the residual amount of chlorine in the 0.5 ~ 1mg / L, in the pipe network is not the end of the residual amount of chlorine should also be maintained in the 0.05 ~ 0.1mg / L, the activated carbon can be generally the residual amount of chlorine adsorbed in the tap water to remove more than 99%, in addition, there are a large number of hydroxyl and carboxylic acid and other functional groups on the surface of the activated carbon can be a variety of nature of the Organic substances for chemical adsorption, as well as electrostatic gravitational force, usually able to remove 63% -86% of colloidal substances, about 50% of the iron, as well as 47% -60% of the organic matter.

3. Automatic food-grade water softener:
Food-grade water softener is composed of automatic control valve, high-quality glass fiber reinforced plastic tank and food-grade resin. Through the food-grade water softener, it can effectively remove calcium and magnesium ions in the water. So that the reverse osmosis equipment will not affect the service life of the reverse osmosis membrane due to scaling during operation. And can be automatically regenerated softened water treatment is the use of cation exchange resin in the exchange of cations, calcium and magnesium ions contained in the water exchange out, the system adopts full-automatic control, no need for manual operation, the water quality is stable.

4、Security filter:
Security filter is the last protection before the raw water enters the membrane. It can effectively remove the pre-treatment leakage of substances larger than 5μm. Mainly to prevent suspended particles into the reverse osmosis membrane elements, membrane surface deposition and contamination of membrane elements.

5、Ozone:
is a broad-spectrum, efficient and rapid sterilizing agent, which can completely kill bacteria and viruses in the finished water.

6、Reverse osmosis device
is mainly composed of high pressure pump, reverse osmosis membrane and control part. High-pressure pump pressurization of raw water, in addition to water molecules can pass through the RO membrane, the other substances in the water (minerals, organic matter, microorganisms, etc.) are almost all rejected outside the membrane, can not pass through the RO membrane and washed away by the high-pressure concentrated water.

Reverse osmosis device is the heart of the project's pre-desalination part, the water treated by reverse osmosis can remove most of the inorganic salts, organic matter, microorganisms and so on. Reasonable design is directly related to the investment cost of the project, the economic efficiency of the whole system operation, service life, operation reliability and simplicity. Reverse osmosis membrane are used in the world's most advanced ultra-low pressure composite membrane, single desalination rate of 99.8%. When the system design temperature is 25 ℃, taking into account the raw water quality changes and the service life of the membrane and other factors, this system uses polyamide composite RO membrane, installed in stainless steel pressure vessel.

Recovery rate: 50-75%, desalination rate: 98%.

General tap water by a reverse osmosis water purification equipment system treatment, water conductivity <10μS/cm, by the secondary reverse osmosis system after the water conductivity <2μS/cm or even more.

Scope of application: suitable for the production of various fruit juices, tea drinks process with pure water, beer brewing process with pure water, dairy process water, vegetable processing, milk with pure water, all kinds of food production with water purification equipment, white wine blending beer production with pure water equipment, food and beverage production with pure water equipment, barrels of pure water, mineral water, hotels, neighborhoods, offices, direct drinking water equipment.
