Our company is in urgent need of a thermal filtration device for use with a hot solution containing approximately 10% sodium chloride and a pH level of around 1; it is necessary to remove the salts from this solution at a temperature of 90–100 degrees Celsius.
Jiangsu Sudong Chemical Machinery Co., Ltd. is here to serve you wholeheartedly: Wang Yongjin, 15961041446
Your medium is a hot solution containing about 10% sodium chloride with a pH of around 1; filtration is required. Under these conditions, sodium chloride crystals should not form, right? Therefore, the so-called solid-liquid filtration separation cannot be achieved; thus, you can only use membrane filters to remove the salts from it.
The temperature is high, the chloride ion content is high, and the corrosivity is severe – it’s quite troublesome. I think a centrifuge would be more suitable!
The opinion on the 3rd floor is correct. The poster’s solution is a salt solution; ordinary filtration methods (sedimentation, centrifugation, etc.) do not work, and only high-pressure membrane filtration is an option.
This is no longer within the scope of solid-liquid separation; membrane filtration is the only viable filtering method, otherwise efforts must be made to improve the process itself
If it’s not crystalline, then it falls outside the scope of solid-liquid separation. You can consult membrane manufacturers about this. If it is a case of solid-liquid separation, we have filters with automatic waste discharge that can be used for filtering liquids with high solid content and high viscosity; they are driven by air pressure
Apply an anti-corrosion coating to the stainless steel filter
Why isn’t cooling to induce crystal precipitation considered? Evaporation could also work; otherwise, people would have to rely on membrane filtration at the atomic level.
