In the process of treating high-concentration organic wastewater via MVR evaporation, foam formation often becomes a major obstacle to stable operation. The overflow of excessive foam not only reduces effective processing space and significantly decreases evaporation efficiency but also can cause secondary pollution, exacerbate equipment corrosion and scaling, and even lead to unplanned system shutdowns, directly increasing operational costs and safety risks.
Facing this common industry challenge, Chemi Tech, through in-depth research on evaporation processes and foam formation mechanisms, has developed a series of targeted MVR wastewater treatment defoamers. Our solution is not simply adding generic agents but is based on systematic analysis of customer water quality, process conditions, and the root causes of foaming. The core products utilize special composite technology of modified polyethers and silicone-based materials, possessing both rapid foam-breaking and long-lasting foam-suppressing capabilities. They are resistant to high temperatures and strong electrolytes, maintaining performance stability in harsh evaporation environments without affecting effluent quality or subsequent processes.
The implementation steps are clear and specific. First, our technical team conducts on-site inspection and foam sample analysis to accurately identify the primary cause of foaming. Subsequently, through laboratory simulations of evaporation conditions, we screen and determine the most suitable defoamer type, initial injection point, and dosage. During the dosing phase, we recommend using metering pumps for precise continuous or intermittent addition, typically at the preheater inlet or circulation pump, to ensure thorough mixing of the chemical with the material stream. During operation, we assist clients in establishing a monitoring system for key parameters such as foam layer height, evaporation rate, and concentration factor, and fine-tune the dosing strategy accordingly to achieve dynamic optimization and cost control.
Practice validates the value of the solution. At an electronic materials manufacturing plant, its MVR system was overwhelmed with foam in the separator when treating cleaning wastewater containing surfactants, forcing reduced load operation. After adopting a customized Chemi Tech defoamer, with precise dosing at the preheating stage, the foam was fundamentally controlled within 72 hours. Evaporation efficiency recovered to over 95% of the design value, and the system operated continuously for three months without a shutdown due to foam. The clarity of sight glasses also improved, facilitating daily observation and maintenance.
Choosing Chemi Tech means choosing a reliable technical partnership. We provide not just products, but a complete support system encompassing diagnosis, testing, application, and optimization, committed to helping users completely overcome foam troubles and ensuring the long-term, efficient, and economical operation of MVR evaporation systems.
