How to deal with the water discharged from the air compressor

The water discharged from the air compressor, that is, condensed water, is mainly composed of a mixture of air compressor oil and condensed water, containing harmful substances such as mineral oil lipids, hydrocarbons and synthetic organic matter. If it is discharged directly without treatment, it will cause serious pollution to the environment and ecology. Therefore, effective measures must be taken to deal with the water discharged from the air compressor. Here are a few common approaches:

1. Oil-water separation

using the oil-water separator, through the principle of gravity separation and filtration, the water and sediment containing oil are separated. The oil-water separator is the key equipment for the oil-water separation of the screw air compressor. It is installed between the air compressor and the air handler. Its core function is to remove the oil and moisture in the high-pressure gas of the brake pipeline to ensure the cleanliness of the compressed gas. The separated water is drained through the drainage device, and the oil is collected for subsequent treatment or reuse.

2. Temporary Storage Processing

concentrate and temporarily store the water discharged from the air compressor and treat it as required. During the temporary storage period, some measures can be taken to reduce the pollution level of the wastewater, such as adding chemical agents. This method has the advantages of simple operation and low cost.

3. Oil immersion method

the wastewater with more lubricating oil can be treated by oil immersion. Put the wastewater into a specific fixed wastewater pool, and add a specific oil immersion agent, so that the grease and other substances are leached into the adsorbent in the fixed wastewater pool to achieve the effect of purification.

4. Microbiological method

the use of microbial degradation of organic matter, the organic matter is decomposed 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

the waste water is partially separated by a centrifuge to remove particles and sediments in the waste water, so as to achieve the effect of purification. This method is simple to operate, high efficiency, and can be recycled.

6. Comprehensive treatment

in practical application, it is often necessary to comprehensively adopt the above-mentioned various treatment methods according to the specific composition and characteristics of the wastewater. For example, preliminary separation can be carried out by an oil-water separator, and then advanced treatment can be carried out by microbial method or centrifugal filtration method, so as to ensure that the wastewater meets the environmental protection discharge standard.

Precautions

• select the appropriate treatment method: Select the appropriate treatment method according to the composition and characteristics of the wastewater to ensure the treatment effect.
• Compliance with environmental regulations: Strictly abide by environmental 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 wastewater treatment.
• Reduce wastewater generation: Minimize the generation and discharge of wastewater and improve resource utilization efficiency.

To sum up, the water discharged from the air compressor must be effectively treated before it can be discharged to avoid environmental and ecological pollution. When selecting the treatment method, the composition, characteristics and treatment cost of the wastewater should be considered comprehensively to ensure the treatment effect and economy.
