Mine Water
wastewater source - Mine Water
During the mining process, groundwater is in contact with rock formations, and with the influence of human activities, a number of physical, chemical and biochemical reactions occur, thus the mine water quality has significant industry characteristics.
Mine water contains much higher TDS content than normal surface water, and a large portion of it is sulfate.
Main case 1
- MVR Evaporation & Crystallization
Sanfeng designs the MVR evaporation system which combines forced circulation evaporation and crystallization, falling film evaporation and crystallization and freezing crystallization to optimize the system with lower energy consumption and lower investment cost.
- Forced circulation evaporation and crystallation
- Falling film evaporation and crystallation
- Freezing crystallation
Main case 2
- Freezing Crystallization
Different from evaporation crystallization, freezing crystallization come from decrease of solubility. Solution will be getting saturated once the temperature decrease. But evaporation crystallization comes from evaporation of water in feeding material.
It is been proved that freezing crystallization suitable for such material which solubility curve shows a clear upward trend. Its solubility varies greatly with temperature.
The material continuously feeding and discharging in the system. The low temperature crystal slurry goes to filter section to get the solid crystal. The mother liquid from crystallizer also has a certain degree of supersaturation, which need to be pumped into the thickener to eliminate supersaturation and then enter centrifuge for solid-liquid separation.
Main case 3
- Fluid Bed Dryer
Fluid bed dryer is a new type of efficient dryer developed in recent years. When in fluid bed, due to vapor and liquid contact in counter-current, with violent agitation, the solid particles suspend in drying medium, having a large contact area. No matter in heat transfer, mass transfer, volume drying and heat efficiency, the dryer has very good performance. Currently it has been widely used in chemical industry, light industry, pharmaceutical industry, food and other industries.
