What are the applications of reverse osmosis water treatment equipment?

Abstract: Reverse osmosis water treatment equipment usually consists of three parts: raw water pretreatment system, reverse osmosis purification system and ultra-clean post-treatment system. Reverse osmosis water treatment equipment is widely used in power industry, electronics industry, food industry, pharmaceutical industry, beverage industry, chemical industry and other fields. So what are the advantages of this equipment? Besides simple operation, easy automation and labor saving, it also has the advantages of compact structure and small occupied area, thus reducing the cost. Let's study related knowledge with Bian Xiao. Application field of reverse osmosis water treatment equipment

1. Power industry: boiler make-up water and cooling dam.

2. Electronics industry: ultrapure water, integrated circuit cleaning water and formulated water for semiconductor industry.

3. Food industry: formula water and production water.

4. Pharmaceutical industry: preparation of process water, preparation water, washing water, water for injection and sterile water.

5. Beverage industry: formula water, production water and washing water.

6. Chemical industry: production water and wastewater treatment.

7. Drinking water project: ultrapure water preparation and drinking water purification.

8. Petrochemical industry: advanced treatment of oilfield injection water and petrochemical wastewater.

9. Seawater desalination: water for production and life in island areas, coastal water-deficient areas, ships and seawater oilfields.

10, in the field of environmental protection: recover precious metals and water from electroplating rinse water to achieve zero or micro-discharge.

Advantages of reverse osmosis water treatment equipment system

1. Fresh water can be extracted from seawater or salt water.

2. It is easy to remove impurities such as organic matter, bacteria and colloid dissolved in water to obtain high purity water.

3. Because the reverse osmosis process is a physical process, there is no phase change, so it saves energy.

4. Simple operation, easy automation and labor saving.

5. Compact structure, small floor space and reduced cost.

6. As a concentration method, valuable components dissolved in the solution can be recovered.

How to clean and maintain reverse osmosis water treatment equipment

First, online cleaning

On-line cleaning refers to cleaning the whole reverse osmosis device, and the membrane element does not need to be taken out of the pressure vessel, so it is usually designed and used in larger systems. This cleaning method is easy to operate and short in time, but it is easy to cause incomplete cleaning and unsatisfactory effect. This method can be used when the pollution of reverse osmosis device is light.

Second, offline cleaning.

Off-line cleaning refers to taking the membrane element out of the reverse osmosis pressure vessel and loading it into special cleaning equipment for cleaning. Usually, the number of times of cleaning is no more than 6 times. This cleaning method is simple and convenient to operate, thorough to clean and has the best effect. However, when there are many membrane elements, the cleaning time is longer. This method can be used when the reverse osmosis pollution is serious or the online cleaning effect is poor.

Three. EDI cleaning

With the increase of working hours, it is necessary to clean and disinfect the EDI module because:

1, hardness or metal scaling, mainly produced in concentrated water chamber.

2. Inorganic dirt is formed on ion exchange resin or membrane.

3. Organic dirt forms on ion exchange resin or membrane.

4. Biological fouling of 4.EDI modules, system pipelines and other components.
