How to deal with water discharged from air compressors
The water discharged from the air compressor, i.e. condensate water, is the main component of the air compressor oil and condensate water, and contains harmful substances such as lipids, hydrocarbons and synthetic organic matters of mineral oil. If discharged directly without treatment, it will cause serious pollution to the environment and the ecology. Therefore, effective measures must be taken to treat the water discharged from the air compressor. The following are several common treatment methods:
1. Oil-water separation
Use an oil-water separator to separate the moisture and precipitates containing oil through the principles of gravity separation and filtration. Oil-water separator is a key equipment for oil-water separation of screw air compressors. It is installed between the air compressor and the air handler. Its core function is to remove oil and water in the high-pressure gas of the brake pipeline to ensure the cleanliness of the compressed gas. The separated moisture is discharged through the drainage device, while the oil is collected for subsequent treatment or reuse.
2. Temporary storage processing
Storage the water discharged from the air compressor and process it as needed. During the temporary storage period, measures such as adding chemicals to reduce the level of wastewater contamination. This method has the advantages of simple operation and low cost.
3. Oil immersion method
For wastewater with more lubricating oil, the oil immersion method can be used for treatment. Put the wastewater into a specific fixed wastewater pool and add a specific oil-impregnant to allow the oil and other substances in it to be leached into the adsorbent in the fixed wastewater pool to achieve the purification effect.
4. Microbial method
Use the degradation of organic matter by microorganisms to decompose organic matter into harmless substances. This method has the advantages of small footprint and no secondary pollution, and can effectively degrade difficult organic matter such as lubricating oil.
5. Centrifugal filtration method
Separate the wastewater by centrifuge to remove particulate matter and precipitate in the wastewater, thereby achieving the purification effect. This method is simple to operate, efficient, and can be recycled.
6. Comprehensive treatment
In practical applications, the above-mentioned treatment methods are often required to be comprehensively adopted based on the specific components and characteristics of the wastewater. For example, initial separation can be performed through an oil-water separator first, and then in-depth treatment by microbial method or centrifugal filtration method to ultimately ensure that the wastewater meets environmentally friendly emission standards.
Precautions
- Select the appropriate treatment method: Choose the appropriate treatment method according to the composition and characteristics of the wastewater to ensure the treatment effect.
- Compliance with environmental protection regulations: Strictly abide by environmental protection regulations and standards to ensure that the wastewater treatment process meets relevant requirements.
- Strengthen equipment management: Strengthen the maintenance and management of wastewater treatment equipment to ensure its normal operation and efficient treatment of wastewater.
- Reduce wastewater production: Minimize the generation and discharge of wastewater and improve resource utilization efficiency.
In summary, the water discharged from the air compressor must be effectively treated before it can be discharged to avoid pollution to the environment and the ecology. When choosing a treatment method, factors such as the composition, characteristics and treatment cost of the wastewater should be comprehensively considered to ensure the treatment effect and economicality.
