In the process of water treatment, the foam problem not only affects the treatment efficiency, but also may cause equipment damage, substandard water quality and even environmental pollution. Choosing the appropriate defoamer is the key to solving this problem, but how can we efficiently select the best solution when faced with numerous types of defoamer products on the market?

First of all, we need to clarify the source and characteristics of foam problems, analyze why foam is produced, whether it is caused by surfactant or mechanical action. Secondly, we need to judge whether the type of foam is permanent or temporary, and select appropriate defoamer products according to water quality conditions. In addition, it can be matched according to the processing technology, such as in biochemical systems, where defoamers that are easy to disperse and do not affect microbial activity can be selected. Membrane treatment systems can choose products that require low residue and no risk of membrane fouling. With the increasing requirements for environmental protection and safety, biodegradable (such as plant-based) defoamer products can be chosen.

It is worth noting that when using defoamer, we can first take on-site water samples, carry out small-scale experiments, observe the foam fading speed and durability, and check whether there are precipitation or failure problems with existing agents.

With the development of science and technology, intelligent and green defoamers are becoming increasingly popular in the future. Efficient selection of defoamers requires consideration of specific water quality, process, and cost, following a validation process optimized through small-scale testing to ensure the long-term stability of water treatment defoamers.
