In many industrial production processes, treating high-salinity wastewater is a common challenge, and the foam problem is especially prominent. A high-salt environment undermines the stability of conventional defoamers, causing them to rapidly decompose and fail, so foam keeps being generated. This not only affects the normal operation of treatment facilities, such as reducing aeration efficiency, hindering solid-liquid separation, and causing overflow, but may also bring environmental and safety risks.
Chemi Tech is well aware of this market pain point. Through in-depth research on how high-salt systems affect surface-active substances, we successfully developed a series of highly efficient defoamers specifically for high-salinity wastewater. Our products use specially structured hydrophobic particles and carriers, and can maintain excellent chemical stability and dispersibility in a high-ionic-strength environment, quickly penetrating the foam wall to achieve long-lasting foam inhibition. Their core advantage lies in withstanding high salt, strong acid, or strong alkali conditions without affecting subsequent biochemical or physicochemical treatment processes.
The specific solution is divided into four steps: the first step is water quality analysis to determine the salt composition, pH value, and temperature range; the second step is targeted product selection, choosing the most suitable Chemi Tech defoamer model according to the water quality characteristics; the third step is an on-site trial to determine, through experiments, the best dosing point (such as the aeration tank inlet or the outlet) and dosage; the fourth step is to establish an automated dosing plan to achieve precise and economical continuous defoaming control.
We once served a metal surface treatment enterprise in East China, whose wastewater had high salinity and contained multiple complex components, and the foam problem had long troubled the pretreatment unit of its zero-discharge system. After on-site diagnosis by our technical team, we recommended our CT-88H model defoamer specially for high salinity. After the customer implemented the integrated dosing plan we provided, the foam was significantly controlled within 24 hours, the defoamer consumption dropped by about 35% compared with the original product, and the system's operating stability was greatly improved, achieving considerable operating cost savings for the customer.
When facing high-salinity wastewater, choosing a stable and efficient defoamer is crucial. With professional products and technical services, Chemi Tech is committed to providing customers across industries with a reliable, economical, ultimate solution to foam problems.
