A few days ago, our Nanhui defoamer received a call from a pharmaceutical company in Shandong, Mr. Yao, asking us for help, can we use aerobic pool defoamer to solve the foam problem. It is understood that Mr. Yao’s company is doing environmental management in response to the national call. The company mainly produces semi-synthetic antibiotics. The wastewater is mainly some tank washing water, containing some ethyl acetate, butyl acetate solvent and amoxicillin. The wastewater COD is 8000-10000, and the daily water volume is about 30 cubic meters. According to the data provided by Mr. Yao, our Li Gong concluded that we recommend the use of our CQ-187 aerobic pool defoamer. The following is the editor based on Li Industrial analysis, summarized the reasons for foaming in the aerobic pool, and what are the advantages of the aerobic pool defoamer.
(Application scenario of aerobic pool defoamer)
Causes of foaming in the aerobic pool:
1. The aerobic pool is often due to various organic pollutants, plant proteins, biological proteins, especially high molecular colloidal protein substances secreted on the surface of microbial cells, etc. The influent water contains a relatively high concentration of surfactants. , Oily substances and other substances that are prone to foam.
2. If the aerobic tank is operating under high load, if most of the organic matter in the wastewater is not effectively degraded, the activated sludge is therefore in a highly active state and is dispersed and suspended, making it difficult to form flocs. At this time, the water is rich in colloidal substances and proteins produced by various organic substances and microorganisms, which will form a large amount of foam.
3. When the aerobic tank is in ultra-low load operation for a long time, it will inevitably cause the sludge to age, and even the sludge will disintegrate to different degrees. At this time, the accumulation of foam will form on the liquid surface of the aerobic tank, and it will form at this time. The form of the foam is very different from the foam formed by high load. The characteristic is that the foam bubbles are large and soft. Most of them are yellow-brown and black due to the attachment of fine sludge flocs. The stacking height is far less than the foam formed by high load.
Advantages of aerobic pool defoamer:
Fast defoaming, does not affect the progress of water treatment, water quality index detection and discharge, low COD, high cost performance, easy to disperse in water, well compatible with liquid products, not easy to demulsify and float oil, widely used in various types The water treatment industry performs defoaming and foam suppression.
Antifoaming agent is a very commonly used auxiliary in industry and life. The above is a summary of the editor's experience. I hope that you will have a good reference when choosing a defoaming agent. Choose the defoamer that suits you.
