Separation equipment
Thread Content
Hello, everyone! During the evaporation process of saline wastewater in our company, the high content of organic substances results in fine salt crystal particles. Could anyone recommend suitable separation equipment? (We have previously used horizontal piston-fed centrifuges and horizontal spiral centrifuges.)
An introduction to the entire manufacturing process! Wastewater components!
For wastewater with a COD of 120,000 mg/L, ammonia nitrogen at 30,000 mg/L, and salt content (ammonium chloride) of 150,000 mg/L, the treatment process involves first using the Fenton method, followed by MVR evaporation, and then salt separation.
If the previous process is not to be altered, a fully automatic scraper-type discharge centrifuge can be used!
For MVR evaporation and the separation and liquid removal of ammonium chloride, the centrifuges most commonly used are the 1: two-stage piston-fed centrifuges of the HR series, especially when the particle size of the solid phase is greater than 0.05 mm. 2: Horizontal spiral discharge filter centrifuge LLW series, for solid particle sizes greater than 0.06 mm. 3: Horizontal spiral discharge sedimentation centrifuges of the LW series (used when the organic content is high and the crystals are fine). 4: When the amount of solid phase is very low, various flat-bed centrifuges from the PGZ, PD, and PS series are used.
A discharge centrifuge or a sedimentation filtration centrifuge could be considered. . . . . Specifically designed for materials containing organic substances coming out of the evaporator. . . .
Thanks to technological advancements, double-piston feed centrifuges can also be used for fine salt crystal particles; these improved centrifuges are well-suited for handling materials with low concentrations and fine particles.
