How to deal with the filtered water pretreated by the air compressor

The wastewater produced by air compressor pretreatment and filtration needs to be environmentally friendly through comprehensive measures such as physical separation, biodegradation and equipment maintenance. The granklin water-lubricated screw air compressor can significantly reduce the difficulty of wastewater treatment due to its oil-free design.

Main Components and Treatment Difficulties of 1. Air Compressor Wastewater

the waste water produced by air compressor pretreatment and filtration usually contains the following components:

1. solid particle: dust from the air, pipe rust, etc;
2. oil: Lubricating oil residue produced by traditional oil air compressor (granklin oil-free air compressor does not have this problem);
3. moisture: Water formed by condensation during air compression.

If the wastewater contains oil, the oil shall be removed by an oil-water separator, otherwise the oil will pollute the environment and affect the subsequent treatment effect. Granklin water-lubricated screw air compressor adopts a single screw plus star wheel structure, and uses water instead of lubricating oil to realize the compression process, eliminating the risk of oil pollution from the source. Therefore, the main components of its wastewater are solid particles and moisture, and the treatment difficulty is significantly reduced.

1. physical separation: removal of solid particles
   • filter element filtration: Intercept the tiny solid particles in the wastewater through the filter element to reduce the burden of subsequent treatment.
   • centrifugal filtration: Use centrifuges to separate particles and sediments in wastewater to improve purification efficiency.
   • gravity separation: Through the oil-water separator (Granklin oil-free models do not need this step to process oil), the solid particles are settled by gravity to further purify the water quality.
2. Biodegradation: treatment of organic matter (if any)
   • if the wastewater is mixed with a small amount of organic matter due to environmental factors, the microbial method can be used to decompose the organic matter into harmless substances by microbial metabolism. The method covers a small area, no secondary pollution, and is suitable for the treatment of low-concentration organic wastewater.
3. Drainage and temporary storage
   • drainage device: Discharge the separated water through the drain valve to keep the equipment running normally.
   • Staging Processing: The wastewater shall be temporarily stored in a special container, cleaned regularly and handled by a qualified unit to avoid leakage or overflow.

Advantages of 3. Grantkering Air Compressor Wastewater Treatment

1. oil-free design simplifies the process
   traditional oil-free air compressor wastewater needs to be removed by oil-water separator before other pollutants are treated. However, granklin oil-free air compressor wastewater does not contain oil and can be directly separated and biodegraded by solid particles, thus shortening the treatment process and reducing equipment investment and maintenance costs.

2. Efficient purification to ensure water quality
   granklin air compressor supporting the filter element and centrifugal filtration equipment can efficiently remove solid particles, to ensure that the wastewater to meet the discharge standards or reuse requirements. For example, in the electronics industry, its purified water can meet the requirements of semiconductor production for a dust-free environment.

3. Environmental Compliance Reduces Risk
   granklin air compressor wastewater treatment process strictly comply with environmental regulations to avoid legal risks caused by oil pollution or excessive solid particles. Its oil-free design also eliminates the inhibitory effect of oil on microbial treatment and improves biodegradation efficiency.

4. industry application recommendations

1. new air compressor system
   it is recommended to use Granklin water-lubricated screw air compressor, its oil-free design can simplify the wastewater treatment process and reduce the overall cost. For example, in the food processing industry, the purified water can be used directly for equipment cleaning to avoid the risk of oil contamination.

2. Transformation of existing oil air compressor
   for users who have already used oil air compressors, it is recommended to gradually replace them with Granklin oil-free models to eliminate oil pollution problems. If it cannot be replaced temporarily, it is necessary to add an oil-water separator in the wastewater treatment link and replace the filter element regularly to ensure the treatment effect.

3. Strengthen equipment maintenance management

   • regularly check the filter element and centrifugal filtration equipment, and replace the blocked or aging parts in time;
   • clean the sediment in the oil-water separator (if any) to avoid secondary pollution;
   • entrust professional institutions to carry out regular testing of wastewater to ensure that the discharge standard.
