Although water treatment defoamers play an important role in improving water quality and ensuring treatment efficiency, there are still some problems encountered in practical applications that affect defoaming effectiveness and treatment costs. Here are some common problems and their solutions.

1、 Improper dosage of defoamer

Excessive use of defoamers may lead to secondary pollution of water quality and increase treatment costs; If the dosage is insufficient, it cannot effectively defoam.

Solution: Determine the optimal dosage through laboratory trials and adjust it in a timely manner based on actual water quality changes. Meanwhile, an intelligent control system is adopted to achieve precise dosing.

2、 Defoamers are incompatible with water quality

Some defoamers may fail or even have side effects under specific water quality conditions.

Solution: Before selecting defoamers, conduct water quality analysis and choose products with good compatibility. For complex water quality, composite defoamers can be considered to enhance adaptability.

3、The issue of residual defoamers

Residual defoamers may affect subsequent processing steps, such as affecting membrane flux and interfering with biological reactions.

Solution: Choose defoamers that are easy to biodegrade or can be removed through simple physical treatment. Add post-processing steps such as activated carbon adsorption and sand filtration in the processing flow to reduce residue.

To sum up, reasonable selection and use of water treatment defoamer, combined with technical innovation and intelligent management, is the key to solve the foam problem in the water treatment process. By continuously optimizing defoaming strategies, water quality can be effectively improved and efficient recycling of water resources can be promoted.
