With the continuous development of technology and the improvement of environmental awareness, solvent recovery unit has become an increasingly popular device. The solvent recovery unit can effectively recover useful substances in wastewater, reduce environmental pollution, and save costs for enterprises. This article will discuss the application of solvent recovery unit.
 

 

 

What is solvent recovery unit？

Solvent recovery unit is a device used to recover useful substances in wastewater. The solvent recovery unit recovers the useful substances in the wastewater into the solution through a series of filtration and treatment steps to achieve the purpose of recovery.
 

 

Application field of solvent recovery unit

1. Electroplating industry

In the electroplating industry, the chemicals used often contain a large number of useful substances, such as metal ions, organic substances, etc. And these chemicals can produce a large amount of waste water during use, and the useful substance contained in these waste water often causes waste. By using the solvent recovery unit, the useful substances in these wastewaters can be recovered into the solution to achieve the purpose of saving resources.

 

2. Semiconductor industry

In the semiconductor industry, the chemicals used often contain high-purity useful substances, such as silicon and germanium. These chemicals also produce a large amount of waste water during use, and the useful substances contained in these waste water often cause waste. By using the solvent recovery unit, the useful substances in these wastewaters can be recovered into the solution to achieve the purpose of saving resources.

 

3. Pharmaceutical industry

In the pharmaceutical industry, the chemicals used often contain high-purity useful substances, such as biological reagents, etc. These chemicals also produce a large amount of waste water during use, and the useful substances contained in these waste water often cause waste. By using the solvent recovery unit, the useful substances in these wastewaters can be recovered into the solution to achieve the purpose of saving resources.

 

4. Other areas

Solvent recovery unit can also be applied in other fields, such as textile industry, cosmetic industry, etc. The chemicals used in these industries often contain a large amount of useful substances. By using the solvent recovery unit, the useful substances in these wastewaters can be recovered into the solution to achieve the purpose of saving resources.

 

5. Chemical companies

Chemical industry is one of the main application areas of solvent recovery machines. In the process of chemical production, a large amount of waste solvents will be produced. If these waste solvents are not treated, they will pollute the environment. By using a solvent recovery machine, the waste solvent can be recovered to reduce pollution and save costs.

 

6. Printing industry

During the printing process, a large amount of solvents are used, and these solvents generate a large amount of waste liquid. By using a solvent recovery machine, the solvent in the waste liquid can be recovered to reduce costs and pollution.

 

7. Automotive Manufacturing

In the car manufacturing process, a lot of paint and solvents are used. These paints and solvents generate large volumes of waste liquid. By using a solvent recovery machine, the paint and solvent in the waste liquid can be recovered, reducing costs and pollution.

 

8. IT

The electronics industry is also one of the application fields of solvent recovery machines. In the electronics manufacturing process, a lot of solvents are used. These solvents generate large volumes of waste. By using a solvent recovery machine, the solvent in the waste liquid can be recovered to reduce costs and pollution.
 

 

 

How the solvent recovery unit works?

The working principle of solvent recovery unit is more complicated, but it can be simply summarized as the following steps:

 

1. filter

The wastewater first passes through a filtration system, which removes most of the solid particles and suspended matter. This process can use methods such as physical filtration, chemical filtration or biological filtration.

 

2. Neutralization

Wastewater often contains acidic or alkaline substances, which need to be neutralized through neutralization. Neutralization can be accomplished by adding alkaline or acidic substances.

 

3. Precipitation

After neutralization, some metal ions or other substances in the wastewater will form precipitates. These precipitates need to be separated by sedimentation tanks or centrifuges.

 

4. Membrane separation

Membrane separation is the most critical step in solvent recovery unit. In this step, the useful substances and water in the solution are separated by using special membrane filtration technology. This process can use different membrane materials and technologies such as reverse osmosis membranes, ion exchange membranes, and microfiltration membranes.

 

5. Recycling

Finally, through a series of processing steps, the useful substances in the solution are recovered. These useful substances can be used again in the production process to achieve the purpose of saving resources and reducing pollution

 

 

Advantages of solvent recovery unit:

Save resources

By recycling useful substances in wastewater, these substances can be avoided from being wasted, and the purpose of saving resources can be achieved.

 

Reduce pollution

If the useful substances in wastewater are discharged into the environment, they will pollute the environment. By using the solvent recovery unit, these useful substances can be recovered to reduce pollution.

 

Cut costs

By recycling useful substances in wastewater, the procurement cost of enterprises can be reduced. In addition, due to the continuous strengthening of environmental protection regulations, the restrictions on wastewater discharge are becoming stricter, and companies may need to pay fines if they cannot meet these limits. By using a solvent recovery unit, you can reduce the risk of fines for your business.

 

Improve efficiency

By recycling useful substances in wastewater, the discharge of wastewater can be reduced and the production efficiency of enterprises can be improved.
