In the production process of paint shops, the water treatment system is a key link for ensuring process stability and compliant wastewater discharge. However, factors such as pretreatment chemical residues, surfactant accumulation, and high-speed agitation in circulating water systems often cause large amounts of persistent foam. This foam not only overflows tanks and contaminates the working environment, but can also seriously affect spray quality, causing defects such as craters and fisheyes in the coating. At the same time, foam reduces water treatment efficiency and increases downstream treatment costs.
Faced with this common industry pain point, Chemi Tech has conducted in-depth research and launched a highly targeted series of defoamers specifically for paint shop water treatment. Our solution is not simply about adding a generic chemical; it is based on in-depth analysis of the water quality in coating processes.
The solution steps are clear and well defined. First, diagnosis and analysis. Our technical support team will determine the root cause of the foam, whether from degreasers, phosphating solutions, or resin residues, through on-site or sample analysis. Second, grade selection and matching. Based on water quality characteristics such as pH, temperature, and system composition, we select the most suitable model from the Chemi Tech defoamer library to ensure both rapid foam breaking and long-lasting foam suppression. Third, precise dosing. We guide customers to determine the optimal dosing point, such as the circulating water tank, overflow tank, or a specific process section, and the optimal dosage to achieve the best results at minimal cost. Fourth, performance tracking and optimization. We provide follow-up services to adjust the solution as the system changes, ensuring long-term stability.
We once served a company specializing in metal parts coating. The circulating water tank on its pretreatment line produced large amounts of stubborn foam every day due to degreaser accumulation, forcing workers to clean frequently and increasing the defect rate of coated workpieces. After applying the Chemi Tech customized defoamer solution, the foam was significantly controlled within 24 hours of dosing, the surrounding environment became clean, and spray quality returned to normal. The improved system stability also reduced water waste and excessive chemical consumption caused by foam.
Choosing Chemi Tech means choosing not just a product, but a reliable system solution. We are committed to helping paint shops overcome foam problems in water treatment, improving overall production efficiency and quality control, and achieving smoother, more economical operations.
