Choosing the appropriate defoamer is crucial for the effectiveness of water treatment. Different types of water treatment processes and water quality conditions have varying performance requirements for defoamers. Therefore, mastering the selection and matching principles of defoamers is the key to ensuring the effectiveness of water treatment.

Selection principle

 

Targeted: Select appropriate defoamer according to specific water treatment process (such as sedimentation, filtration, aeration, etc.) and water quality characteristics (such as pH value, temperature, foam type, etc.).

Efficiency: Defoamer shall be able to quickly and effectively eliminate or inhibit foam, with low dosage and high efficiency.

Compatibility: Ensure that defoamers are compatible with other chemicals in the water treatment system (such as coagulants, flocculants, etc.) and do not produce adverse reactions.

Environmental friendliness: Use non-toxic, harmless, and easily degradable defoamers to reduce the impact on the environment.

 

Matching principle

 

Performance matching: select appropriate defoamer type according to the nature of foam (such as stability, viscosity, etc.).

Economic matching: Considering the cost-effectiveness of defoamers, choose products with high cost-effectiveness while ensuring effectiveness.

Operation matching: Ensure that the method of adding defoamers (such as direct addition, diluted addition, etc.) matches the on-site operating conditions.
