1. Background

With the increasing global pollution and people’s urgent pursuit of health, more stringentreguirements have been put forward for the food and beverage industry. Ordinary municipal tap wateror deep underground well water has been very diffcult to meet people’s needs. China currently has afood hygiene and safety licensing system (QS certifcation) in place for many foods and all beverageindustries, which reauires that the process and fnished water used to be purifed, Reverse osmosissystems can be made larger than a certain osmotic pressure of the solution according to the differentosmotic pressures of different substances. This results in the separation, extraction, purifcation, andconcentration of the solution.

With the increasing maturity of reverse osmosis technology, its economic and environmentaladvantages are more prominent, and therefore it is widely used in food, beverage, wine, and water aswell as seawater desalination.

2. Food and Beverage Water StandardsInternational health standards for drinking water commonly used for food and beverages are asfollows.

a.Free from physical, chemical, and biological contamination that is harmful to human health:

b.lt contains the right amount of minerals that are benefcial to human health and in an ionic state(potassium, magnesium, calcium, etc. in 100mg/L);

c.Water has small molecular groups and strong solvency and permeability;

d.lt should be weakly alkaline (PH value of 8-9);

e.The water contains dissolved oxygen (about ómg/L) and carbonate ions;

f.lt can quickly and effectively remove acidic metabolites and various harmful substances from thebody;

g.The water hardness is moderate, between 50 and 200mg/L (in terms of calcium carbonate).

Some companies in the food and beverage industry have very high water quality requirements CHUANYI RO systems can be combined with pre-treatment, deionization systems, ion exchangesystems, EDl systems, UV water sterilizers, etc, to meet different water quality requirements, which isan economic and ideal water treatment method.

3.What is Reverse Osmosis Treatment?

The principle of reverse osmosis water production is that the raw water is fltered under pressurethrough the reverse osmosis membrane with a diameter of only 0.0001 microns to obtain pure waterwhile ions, organic matter, bacteria, viruses, etc, are retained on the inlet side of the membrane toachieve the purpose of separation and purifcation.

The production process of reverse osmosis water is low in energy consumption, fast in waterproduction, safe, and a purely physical process without chemical reactions. This economical, practical.safe, and effcient way of water production has been adopted by more and more food and beverageplants.

4.Composition of Chuanyi Water Treatment Reverse Osmosis System in Food and Beverage Factories

CHUANYI’s reverse osmosis treatment equipment is designed for food and beverage processing plantsin various industries, which can effectively remove minerals, organic components, harmful impurities.and microorganisms in water, without any additives (except ozone) water that can be directlyconsumed, and produce high-guality water, without interruption of water production, which can beautomatically controlled, pollution-free, safe, economic and effcient.

The pretreatment of reverse osmosis pure water equipment: consists of an automatic sand flter,automatically activated carbon flter and automatic water softener.

1. Automatic sand flter: lt is composed of an automatic control valve, a glass steel tank, and quartzsand of different grade ratios. lt can effectively remove the suspended matter and some colloidalsubstances in the raw water, reduce the turbidity of the raw water, and can automatically backwashQuartz sand fltration is the preliminary treatment in advance before the water refning treatment, soas to achieve good results in the water refning treatment and improve water quality.

2. Automatically activated carbon flter: Activated carbon flter is composed of an automatic controvalve, high-quality glass jar, and different water purifcation grade activated carbon. lt can effectivelyadsorb heavy metals, free chlorine, chloroform, and other harmful substances in the raw water andremove the odor and taste in the water. Activated carbon can generally remove more than 99% of theresidual chlorine in tap water by adsorption. In addition, the use of activated carbon can also remove63%-86 colloidal substances, about 50 iron, and 47%-60% oforganic matter.

3. Food-grade water softener: lt is composed of an automatic control valve, a high-quality glass steeltank, and food grade resin. Through the food-grade water softener, it can effectively remove thecalcium and magnesium ions in the water, So that the operation of reverse osmosis equipment will notaffect the service life of the reverse osmosis membrane due to scaling. This system adopts fullyautomatic control, no manual operation is needed, and the water quality of the output is stable.

• Security flter: The security flter is the last protection before the raw water enters the membrane. ltcan effectively remove substances larger than 5u m from the pre-treatment leak. The main purpose isto prevent suspended particles from entering the reverse osmosis membrane element andcontaminating the membrane element by depositing it on the membrane surface.

5. Ozone: lt is a broad-spectrum efhcient and fast sterilizing agent, which can completely kill thebacteria and viruses in the finished water.

6. Reverse osmosis device: lt is mainly composed of a high-pressure pump, RO membrane, andcontrol part. The high-pressure pump pressurizes the raw water, and the reverse osmosis unit is thecore part of the system. The water treated by reverse osmosis can remove most of the inorganic salts,organic matter, microorganisms, etc.

CHUANYI’s most advanced ultra-low-pressure composite membrane, with a single desalination rate of99.8%, is directly related to the investment cost of the project, the economic effciency of the entiresystem operation, service life, and the reliability and simplicity of operation. Recovery rate:50-75%desalination rate:98%.

Considering the variation of raw water quality and the service life of the membranes, the CHUANYI treatment system uses polyamide composite RO membranes, installed in stainless steelpressure vessels. Generally, after the frst level reverse osmosis water purifcation equipment system,the conductivity of the produced water is <10 u S/cm, and the conductivity of the produced water is<2u Slim or even lower after the second level reverse osmosis system.

5.Chuanyi Water Treatment Reverse Osmosis Equipment in the FoodIndustry

(1)Reverse osmosis equipment for the food industry

With the progress and development of society, people are more and more concerned about foodhygiene. In food processing, the raw material water needs to be fltered to ensure the quality of thefood produced. At present, the market sales of water treatment devices in a variety of forms andvarieties, their structure is not reasonable to design, install and disassemble are not convenient to use.resulting in low effciency and poor fltration of raw water. This requires multiple cycles of fltration ofraw material water, which makes many companies fall into the problem oftime-consuming fltrationprocesses, energy consumption, and other problems, and it is difhcult to achieve effcient and stablefltration of raw material water for food processing needs.

CHUANYI adopts the primary reverse osmosis process to prepare high-quality water for food processproduction without chemical reagents and additives, the product is not contaminated by the outsideworld, and the separation device is simple to operate and easy to control. lts technical characteristicsare as follows:

a.The operation process is carried out at room temperature without temperature change.

b.The product quality and economic benefts are better.

c.Low energy consumption, only 1/2~1/3 of traditional evaporation concentration and freezingconcentration methods.

The operation flow of this reverse osmosis system is as follows:

Raw water tank→ Booster pump- Multi-media flter→Activated carbon flter-Security flter -High-pressure pump- Primary reverse osmosis – Pure water tank.

The water treated by the equipment can go to most of the inorganic salts, organic matter. microorganisms, etc., in order to meet the water requirements of the food industry.

(2) Chuanyi Water Treatment RO equipment for the preparation of purifed water

CHUANYI mainly uses a two-stage reverse osmosis process to prepare pure water. Two-stage reverseosmosis pure water equipment is the frst stage of reverse osmosis through the water after adjustingthe PH value, and then by the second stage of the high-pressure pump into the second stage of reverseosmosis system processing, so as to obtain pure water process.

Generally, after the frst stage reverse osmosis system, the conductivity of the produced water is <10uS/cm, and after the second stage reverse osmosis system, the conductivity of the produced water is<5u S/cm or even lower. This effectively removes organic salts, heavy metals, organic substances.carcinogens, bacteria, viruses, and other toxic and harmful substances that are harmful to humanhealth, ensuring the purity and safety of mineral water.

The process is as follows: The process is as follows: raw water tank- booster pump- multi-mediaflter – activated carbon flter -security flter- high-pressure pump- primary reverse osmosishigh-pressure pump-secondary reverse osmosis – pure water tank-ozone sterilization -fnishedwatertank→pure water pump-microporous flter-flling.
