Dissolved air flotation machine is an efficient water treatment equipment widely used in the treatment of various types of wastewater, especially in the fields of industrial wastewater, sewage treatment, and drinking water treatment. It mainly achieves solid-liquid separation by dissolving air into water and releasing it into tiny bubbles, using the adhesion of the bubbles to lift suspended solids, oils, fine particles, and other substances in the water.
The dissolved air flotation machine has good adaptability in treating various types of water quality, but its ideal effect is usually reflected in the following water quality types:
1. Oil containing wastewater
One common application is the treatment of oily wastewater. Oily wastewater is usually present in wastewater treatment in industries such as chemical, petroleum, food processing, and papermaking. The density of oil in this type of wastewater is relatively low and usually evenly distributed. The air flotation machine can separate oil from water through the adsorption of bubbles.
Applicability: Able to adapt to situations with large fluctuations in oil concentration.
Advantage: Oil has strong buoyancy and can effectively lift oil stains through microbubbles, ensuring that the effluent quality of wastewater meets the standard.
2. Industrial wastewater
Many industrial wastewater contains a large amount of suspended solids, sediment, and harmful substances, which require efficient separation methods for treatment. It can achieve good results in these situations, especially widely used in the following industrial wastewater:
Steel metallurgy: The wastewater generated during the steel smelting process usually contains a large amount of suspended solids and oil pollution, which need to be removed.
Paper mill: The wastewater generated during the papermaking process contains a large amount of fiber residue, which can be separated from these solid particles.
Food processing: Wastewater generated during processes such as frying and refining edible oils usually contains a large amount of oil and suspended solids, which can be efficiently separated by air flotation machines.
3. Urban sewage
The same applies to urban sewage treatment, especially for oils and suspended solids in sewage. It can effectively remove these pollutants and reduce the burden of subsequent treatment.
Applicability: It can remove pollutants such as oil, fat, and suspended solids from sewage, and plays an important role in the post-treatment of primary sedimentation tanks in urban sewage treatment.
Advantages: Fast processing speed, stable processing effect, and small footprint.
4. Drinking water treatment
Although dissolved air flotation machines are not as widely used in drinking water treatment as in wastewater treatment, they can still play a role in certain specific situations, especially in removing particulate matter and organic matter from water.
Applicability: It can remove fine suspended solids, algae, and organic matter from water and improve water quality.
Advantages: Its ability to efficiently remove small particles can effectively improve water quality and is suitable for drinking water treatment with special requirements.
Dissolved air flotation machines have a wide range of applications in different types of water quality and quantity. It is mainly suitable for the treatment of oily wastewater, industrial wastewater, urban sewage, and drinking water, and has significant advantages in the treatment of suspended solids, oils, and sediments. When selecting, customers need to consider the actual water quality situation and treatment needs, and choose the appropriate equipment model to ensure the long-term stable operation and treatment effect of the equipment.
