In the waste incineration process, the wastewater produced has a complex composition and contains a large amount of surface-active substances and organic impurities. These substances very easily form stubborn and lasting foam in the subsequent aeration, stirring or biochemical treatment stages. Such foam not only overflows from the tank and causes environmental pollution, but also seriously hinders oxygen transfer, affects microbial activity, reduces treatment efficiency, and may even damage pumps, instruments and other equipment, increasing operation and maintenance costs and safety risks.
The market generally faces pain points such as large defoamer dosage, short-lived effect, poor foam-suppressing performance, or residues of the product itself affecting water quality and subsequent processes. In response to these challenges, Chemi Tech, with its professional research and development, has launched a series of highly efficient defoamers dedicated to waste incineration wastewater. Our solution aims to control foam at the root rather than simply eliminating it temporarily.
Our solution is divided into three core steps. The first step is precise diagnosis and analysis. By analyzing your wastewater quality, process nodes and foam characteristics, we recommend the most suitable defoamer model. The second step is product application and integration. Chemi Tech defoamers have excellent dispersion and durability and can maintain high efficiency under harsh conditions of high temperature, high alkalinity and the presence of various interfering substances. It is usually recommended to add them by continuous dripping or metering pump dosing at sections prone to foaming, such as the inlet of the aeration tank or the coagulation reaction tank; the initial dosage is determined according to the severity of the foam. The third step is effect optimization and tracking. Our technical team will help customers adjust to the optimal addition point and dosage to ensure long-term stable defoaming and foam-suppressing effects at the lowest cost, and the product has good biodegradability and does not affect the final discharge indicators of the wastewater.
For example, in a resource recovery project in East China, its wastewater produced a large amount of foam when entering the biochemical system after physical and chemical pretreatment, and various general defoamers had been used with poor results. After adopting Chemi Tech's customized formula and continuously dosing at a very low dose at the inlet end of the biochemical tank, the foam was significantly controlled within 24 hours and the tank surface returned to clear. In subsequent operation, the dissolved oxygen concentration of the biochemical system remained stable, the treatment efficiency increased by about 15%, and no aggravated equipment scaling or membrane fouling was found. The customer was satisfied with the stability and economy of long-term operation.
Choosing Chemi Tech means choosing a partner focused on complex industrial fluid problems. We provide not only products but also full-process technical support from problem diagnosis to continuous optimization, ensuring that your waste incineration wastewater treatment system operates efficiently, stably and foam-free.
