Chemi Tech Waste Incineration Wastewater Defoamer: Efficient Foam Control for System Stability

During waste incineration, the generated wastewater has complex components containing substantial surfactants and organic impurities. These substances readily form persistent and stable foam during subsequent aeration, agitation, or biological treatment stages. This foam not only overflows from tanks causing environmental concerns but also severely impedes oxygen transfer, affects microbial activity, reduces treatment efficiency, and may even damage pumps, instruments, and other equipment, increasing operational costs and safety risks.

The market commonly faces pain points such as high defoamer dosage, short-lived effectiveness, poor foam suppression, or defoamer residues affecting water quality and downstream processes. To address these challenges, Chemi Tech leverages dedicated R&D to offer a series of high-efficiency defoamers specifically designed for waste incineration wastewater. Our solution aims to control foam at its source rather than providing a temporary fix.

Our solution involves three core steps. Step one is accurate diagnosis and analysis. By evaluating your wastewater characteristics, process points, and foam properties, we recommend the most suitable defoamer product. Step two is product application and integration. Chemi Tech defoamers exhibit excellent dispersibility and persistence, maintaining high efficiency under harsh conditions including high temperature, high alkalinity, and the presence of various interfering substances. They are typically recommended for continuous drip or metered pump feeding at foam-prone stages, such as the inlet of aeration tanks or coagulation reactors, with initial dosage determined by foam severity. Step three is performance optimization and follow-up. Our technical team assists clients in fine-tuning the optimal feed point and dosage to ensure long-term, stable foam control at the lowest cost. Our products are designed with good biodegradability and do not compromise final effluent discharge standards.

For instance, a resource recovery project in Eastern China experienced severe foam generation when pretreated wastewater entered the biological system. Various generic defoamers had proven ineffective. After switching to a customized Chemi Tech formulation, fed continuously at a very low dose at the bio-tank inlet, foam was significantly controlled within 24 hours, and the tank surface became clear. In subsequent operation, dissolved oxygen levels in the biological system remained stable, treatment efficiency improved by approximately 15%, and no increased equipment scaling or membrane fouling was observed. The client expressed satisfaction with the long-term operational stability and cost-effectiveness.

Choosing Chemi Tech means partnering with a specialist in complex industrial fluid challenges. We provide not just products, but comprehensive technical support from problem diagnosis to continuous optimization, ensuring your waste incineration wastewater treatment system operates efficiently, stably, and foam-free.
