In the process of treating high-concentration organic wastewater by MVR evaporation, foam often becomes a stumbling block to stable operation. The overflow of large amounts of foam not only reduces the effective treatment space and significantly lowers evaporation efficiency but may also cause secondary pollution, aggravate equipment corrosion and scaling, and even lead to unplanned system shutdowns, directly driving up operating costs and safety risks.
Facing this common industry challenge, Chemi Tech, through in-depth research on evaporation processes and foaming mechanisms, has developed a series of targeted MVR wastewater treatment defoamers. Our solution is not a simple addition of a general-purpose additive but is based on a systematic analysis of the customer's water quality, process conditions, and root causes of foaming. The core product uses a composite technology of specially modified polyether and silicone materials, offering the dual effectiveness of rapid foam breaking and durable foam inhibition, and it resists high temperatures and strong electrolytes, maintaining stable performance in harsh evaporation environments without affecting effluent quality or subsequent processes.
The specific implementation steps are clear and well-defined. First, our technical team will conduct an on-site survey and analyze foam samples to precisely identify the main cause of foaming. Then, by simulating evaporation conditions in the laboratory, we screen and determine the most suitable defoamer model and the initial addition point and dosage. During the dosing stage, we recommend using a metering pump for continuous or intermittent precise addition, usually at the preheater inlet or the circulation pump, to ensure full mixing of the agent with the material. During operation, we will help the customer establish 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 verifies the value of the solution. At an electronic materials manufacturer, when its MVR system treated cleaning wastewater containing surfactants, foam filled the entire separator and the system was forced to run at reduced load. After adopting Chemi Tech's customized defoamer and dosing precisely at the front-end preheating stage, the foam phenomenon was fundamentally controlled within 72 hours, the evaporation efficiency recovered to more than 95% of the design value, and no foam-induced shutdown occurred during three months of continuous operation. The clarity of the equipment sight glass was also improved, making daily observation and maintenance easier.
Choosing Chemi Tech means choosing a reliable technical partnership. We provide not only products but also a complete support system covering diagnosis, testing, application, and optimization, committed to helping users completely escape the trouble of foam and ensuring the long-term, efficient, and economical operation of MVR evaporation systems.
