The main ways of adding defoamers include direct addition, dropwise addition, and spraying. Before adding, the appropriate addition point and amount should be determined based on factors such as water quality, treatment process, and defoamer performance. Dose control is the key to ensuring defoaming effect, excessive dosage may cause waste and pollution, while insufficient dosage cannot achieve the expected effect.

To ensure the uniform distribution and full effectiveness of defoamers in water bodies, appropriate mixing methods need to be used to improve mixing uniformity. At the same time, the defoaming effect needs to be regularly evaluated, including indicators such as foam reduction and treatment efficiency improvement, so as to adjust the dosing strategy in time.

During the water treatment process, multiple agents are often required to be added, so it is necessary to test the compatibility of defoamers with other agents. Avoid reducing effectiveness or producing harmful substances due to reactions between drugs. Optimizing the application of defoamers in the process flow can further improve the treatment effect. For example, adding defoamer in the front section of the aeration tank can effectively control the generation of foam; During the sludge treatment stage, appropriate types and dosages of defoamers can be selected based on the properties of the sludge.

With the development of technology, more and more water treatment plants are adopting online monitoring and automatic regulation technology to manage the use of defoamers. Intelligent management is realized by installing sensors and control systems to monitor the foam situation in real time and automatically adjust the dosage.

During the use of defoamer, problems such as uneven dosing and rebound of foam may be encountered. At this point, it is necessary to promptly investigate the cause of the malfunction and take corresponding measures to handle it. For example, adjusting the position of the injection point, adding mixing equipment, or changing the type of defoamer.

To ensure the long-term stable operation of the defoamer system, regular maintenance work is required. This includes cleaning the dosing equipment, checking the accuracy of sensors, and replacing aging components. At the same time, attention should be paid to protecting surrounding equipment from damage caused by defoamers.
