Seeking help from experts! Saltwater and salt mud treatment

In the ion-exchange membrane electrolysis process for treating saline wastewater, the salt sludge generated (also known as saturated salt sludge) represents a processing challenge. Normally, salt sludge is dewatered using plate and frame filtration or other solid-liquid separation techniques. If you are looking for alternatives to plate and frame filter presses, here are some possible techniques: 1. Centrifugal dewatering: Using a centrifuge to remove water from sludge, with high-speed rotation generating strong centrifugal force to separate solids from liquids. 2. Vacuum filtration: Utilizes vacuum force to draw out the moisture from the salt sludge, and achieves solid-liquid separation through media such as filter cloth. 3. Screw dehydrator: It dehydrates the salt sludge by using a rotating screw shaft to push it forward and squeeze out the water. 4. Concentration and sedimentation: Allow the salt sludge to settle and concentrate naturally in a sedimentation tank, and separate out the more concentrated salt sludge by removing the supernatant liquid. 5. Flotation: In some special cases, flotation technology can be used to separate solid particles from a liquid. 6. Drying treatment: The salt mud is dried using heating or other drying methods. Although this approach involves higher operational costs, it may be feasible in certain special situations. 7. Chemical treatment: Flocculants or other chemical agents are added to facilitate solid-liquid separation, and the dehydrated salt sludge is then disposed of using one of the aforementioned dewatering devices. Each technology has its own advantages and limitations; choosing the appropriate method requires consideration of the actual processing requirements, equipment investment and operating costs, as well as the desired quality of the output. Due to the significant differences in environmental and economic benefits among various processes, experiments and pilot tests are sometimes required to determine the optimal treatment method. In practical operations, multiple methods are sometimes used together to improve dehydration efficiency and reduce processing costs. .

Salt sludge in brine is like the filling in red bean buns; how can water be extracted from it without pressing and filtering?

Or traditional methods can be used, such as drying in the sun or baking. The disadvantages are the need for a large amount of space, reliance on weather conditions, or a high demand for fuel.

Thank you, I’m just wondering if there are any other filtration methods used in this industry; the boss doesn’t want to use plate and frame filter presses :)
