How to treat the wastewater from the production of sodium saccharin? Can I use MVR technology? Can MVR systems be used in the production of sodium saccharin? Kang Jinghui Xiaobian believes that it is possible to use the MVR concentration system to treat the wastewater generated in the production process of saccharin is a more reasonable way.
Saccharin production industry generally uses the distillation method to treat ammonium chloride wastewater produced in the production process of saccharin, for the treatment process can not overcome the production process links, wastewater components are complex, difficult to treat, high cost of treatment drawbacks, so a more reasonable and stable technology is needed to solve the wastewater generated in the production process of saccharin.
Saccharin sodium production wastewater treatment process selection
For the ammonium chloride wastewater solution produced during the production of sodium saccharin, the method of concentrated crystallization can be used to evaporate the ammonium chloride system crystallization, recover resources, reduce the wastewater generated by the production of saccharin, and reduce the cost for the enterprise.
There are two requirements for process selection:
1. Extract part of the ammonium chloride crystals
2. Reduce the discharge of waste liquid with high impurity content as much as possible
Kang Jinghui technical department for the owner's water quality characteristics designed evaporation crystallization equipment, evaporation crystallization system contains two parts, mainly falling film pre-concentration and forced circulation crystallization, according to the evaporation process designed as a three-effect evaporation crystallization system, are suitable for circulation pump circulation heating concentration, and then combined with MVR crystallization process for wastewater crystallization treatment.
In view of the fact that the boiling point of the ammonium chloride waste liquid may rise to 20 ° C, only a single steam compressor can not meet the temperature rise required for evaporation, so Kang Jinghui will be steam compressor outlet steam for steam jet pump to further heat and pressurize, to obtain the required temperature difference.
The evaporation energy source of the whole system is mainly the steam compressor, and the adjustment of the evaporation capacity of the system is also to adjust the speed of the compressor through the frequency converter to try first, and the consumption of steam depends on the boiling point of the end-effect solution and the influence of impurities.
Those who are interested in the detailed technology of this process can send private messages to Xiaobian.
