Effectively Tackling Foaming in High-Salinity Wastewater with Chemi Tech's Professional Defoamers

Foaming in high-salinity wastewater is a prominent challenge across various industrial processes. The high-salt environment can destabilize conventional defoamers, causing rapid breakdown and inefficacy, leading to persistent foam. This foam hampers normal operations—reducing aeration efficiency, impeding solid-liquid separation, causing overflow—and may pose environmental and safety risks.

Understanding this market need, Chemi Tech has developed specialized high-efficiency defoamer series for high-salinity wastewater through in-depth research on surfactant behavior in high-ionic-strength systems. Our products utilize uniquely structured hydrophobic particles and carriers that maintain excellent chemical stability and dispersibility in high salinity, quickly penetrating foam lamellae for long-lasting foam suppression. Their core strength lies in tolerating high salt, strong acid, or alkali conditions without interfering with subsequent biological or physicochemical treatment processes.

Our solution involves four key steps: First, water quality analysis to identify salt composition, pH, and temperature range. Second, targeted product selection, choosing the most suitable Chemi Tech defoamer type based on water characteristics. Third, on-site pilot testing to determine the optimal injection point (e.g., aeration tank inlet, outlet) and dosage. Fourth, establishing an automated dosing program for precise, economical, and continuous foam control.

We served a metal surface treatment facility in East China. Their wastewater had high salinity and complex components, with foaming persistently troubling the pretreatment unit of their zero-liquid-discharge system. After on-site diagnosis by Chemi Tech's technical team, we recommended our CT-88H high-salinity specialty defoamer. Implementing our integrated dosing plan, the client observed significant foam control within 24 hours. Defoamer consumption reduced by approximately 35% compared to the previous product, greatly enhancing system stability and delivering substantial operational cost savings for the client.

Choosing a stable and efficient defoamer is critical for managing high-salinity wastewater. With professional products and technical support, Chemi Tech is committed to providing reliable and economical ultimate solutions for foam-related challenges across industries.
