The sodium salt content in industrial wastewater is too high, causing crystals to form and block the pipelines
Thread Content
Help, the problem we’re facing now is that the sodium salt content in the wastewater is too high; it keeps crystallizing and blocking the pipelines. Do any experts have a way to remove sodium salts from wastewater?
It would be best to know your current water quality report, the sodium content, and the existing treatment methods. There are many ways to handle it; it depends on which one is suitable for modifying your current approach
Pre-treatment can also be carried out using evaporation crystallization.
I’m afraid to ask, what kind of equipment does your company use to treat this wastewater? What preprocessing methods were used?
Desalination treatment is carried out first, using methods such as ED and RO.
Evaporation, followed by crystallization of sodium salts – it’s best to achieve a quality level suitable for industrial-grade salt, which can then be sold. The evaporated condensate is then processed through biochemical methods, resulting in lower operating costs
Control the temperature to prevent crystallization, so that clogging won’t occur. Besides, if crystallization does happen, it must be dealt with. There’s a whole system for MVR evaporation and crystallization, which is used to separate out industrial salt for sale

From what the original poster wrote, it seems that an evaporation device has been installed; the problem is that blockages occur in the pipes when that device is in use. Pipeline blockages in brine evaporation and crystallization systems are quite common. The main reasons for this are as follows: First, the choice of evaporation method is inappropriate; for areas where crystallization occurs, a forced circulation type must be used ； II. The circulation volume of the forced pump in the forced-circulation evaporator is insufficient ； III. The pipeline design is unreasonable, making blockages likely to occur ； IV. Inadequate preventive measures, with a lack of necessary rapid flushing facilities. If the problem still cannot be resolved, you can also consult Bot Environmental Protection
