Acidic waste liquid crystallization process
Thread Content
Acidic waste liquids contain medium-solubility solutes, and saturated solutions crystallize at room temperature; what methods can be used to efficiently separate the crystals from the mother liquor? Is there a mature, complete set of processes? Several challenges are: environmental protection issues are difficult to resolve, and there should be no acidic odor at the site during operation ； Regarding safety issues, proper personal protection is essential ； Pipelines are prone to crystallization and blockage. Do anyone have any good suggestions?
We have pumps for transporting such materials, along with specialized centrifuges to go with them
1. The operation room is enclosed using PTFE panels; 2. A horizontal screw centrifuge is used to separate solid and liquid fluids； 3. Exhaust vents should be installed on all sides opposite the person, to achieve an exhaust velocity of 2 meters per second; this ensures that there is almost no odor when the person operates the centrifuge.
The entire process should preferably take place in sealed equipment and pipelines, and the release of acidic gases into the atmosphere is also not allowed.
The exhaust gas can be discharged into the workshop’s main exhaust system； (As long as the processing capacity permits)
Visit the websites of Sidelite or Jingjin, or call them directly; these two companies are likely to be reliable suppliers for solid-liquid separation
High-salt wastewater can be directly evaporated using a dryer to remove the solidified substances. Vapor emission can be deodorized using a spray tower.
