Seek solid-liquid separation equipment

A centrifuge will work too; a benchtop centrifuge

Centrifuges, or filter-dryers, as well as natural sedimentation, can also help save money.

Or buy a vacuum pump and design a suction filter disk; it’s very simple.

It’s simple: use a filter. However, plate and frame filtration is still the best option. After all, he is the most suitable one.

The plate-and-frame type is already the best solution. There is also a type of belt filter that requires the use of coagulants or similar substances. If sedimentation and separation conditions are available, an inclined plate sedimentation tank is the best choice.

There’s a small mistake here: the solid content in the material is 2.5%. With 600 tons of mother liquor per day, 11 cubic meters of solid material are produced. To obtain this solid material, a belt filter is used; however, flocculants need to be added, and such filters have many moving parts. Acidic materials cause severe corrosion to these devices. Filters and centrifuges are also used in such situations, but when there’s a large volume of water and a lot of solids involved, unloading and transporting the material becomes problematic. Using plate and frame filters is a good option at the moment; we plan to switch to automatic unloading systems. However, one problem is that these systems take up a lot of space, and they also cause significant odor emissions. Given the strict environmental regulations, it’s necessary to enclose the entire area where these plate and frame filters are used for odor absorption, which is quite troublesome. Natural settling takes too long, and a large sedimentation tank is also required. I’ve also considered using stacked spiral filters; these also require coagulants. I plan to give it a try. I was wondering if anyone else has any good filtration options that don’t require high levels of moisture removal from the solids, as this material will go into a reactor later on, where more water will be added.

When it comes to centrifuges, there is surely one that can meet your process requirements. You can choose a horizontal piston-fed centrifuge with a drum lined with fluoroplastic; this will satisfy your process needs. Adding an air shroud and using an exhaust fan to create negative pressure should help meet environmental regulations.

The piston-fed centrifuges have large gaps, so my fine materials will definitely escape. For the production of ammonium chloride, I use both Xiangtan piston-fed centrifuges and Huada spiral-discharge centrifuges; there are also two flat-bottom discharge centrifuges used for removing the finished product
