In painting operations, circulating water systems or wastewater treatment stages often generate large amounts of stubborn foam due to paint residues, surfactants and other substances. This foam not only overflows and makes the site dirty and messy, but also seriously affects water treatment efficiency, causing pumps to run dry, reducing the system's treatment capacity and even shortening equipment service life. How to control foam efficiently and persistently has become a thorny problem for many site managers.
To address this market pain point, Chemi Tech's R&D team conducted an in-depth analysis of paint wastewater systems and launched a dedicated defoamer product. This solution is not a simple addition of an ordinary auxiliary; it is based on a precise grasp of the causes of foam. Our defoamer offers excellent compatibility and durability, capable of rapidly breaking foam and suppressing it over the long term in complex systems where paint residues and chemicals coexist, without affecting subsequent water treatment processes.
The specific implementation steps are clear and simple. First, our engineers can help analyze foam samples and assess foam characteristics and water quality conditions. Second, based on the assessment results, we recommend a suitable defoamer grade and initial dosage ratio. Users only need to dose at the point where foam is generated or upstream in the circulating water loop; continuous drip feeding or metering pump addition is usually recommended to maintain an effective concentration in the water. Finally, by continuously monitoring foam height and system operating parameters, the dosage can be fine-tuned to achieve optimal cost control and defoaming results.
We once provided support to an enterprise specializing in surface spraying of metal parts. Its existing wastewater treatment line had to be frequently shut down for cleaning due to severe foam overflow, resulting in low efficiency. After adopting a customized Chemi Tech defoaming solution, the foam was significantly controlled on the very day of dosing, the system resumed continuous and stable operation, the cleaning frequency of the subsequent treatment tank dropped sharply, and overall operational efficiency improved effectively.
Choosing Chemi Tech means choosing professional capability dedicated to solving complex industrial foam problems. Our products are committed to helping customers maintain a clean and safe production environment and ensuring smooth and efficient water treatment systems, thereby creating steadier and more economical long-term operational value.
