I work in project to be precipitated paint from thinner but i don't know how to do that . I find some information from internet . it show me how to
settle paint from wastewater but I don't sure thinner use same as water. coagulant were I found = Fenton's regent , Chitosan , Feric chloride and alum
but i not sure it is soluble in thinner like water
Plz help me how to be precipitated paint from thinner
PS. Sorry i am very poor in english But i want let u help me PLZZZZZZZZZZZZ

I don't understand what you mean by 'coagulation'. Does the word in your language have any other translations?

Neutrino, it is like when extracting lactose from milk you add acetic to the milk to coagulate the protein. Its pretty much the same as a catalyst
for precipitation.
Couldent you add the paint in thinner to water (if it is soluble) and then coagulate from there. Or it might be easier to distill the thinner out.

Sorry : I mean how ( to be precipitated, to settle, to be deposited ) paint from thinner / I use thinner for washing paint

So you want to seperate the solvent from the pigment?
If nothing else, it can be distilled off.

first thing I thought of was dropwise addition into a nonsolvent for the paints binder (like water or another solvent the polymer part of the paint
wont be soluble in), but I think distillation sounds best.

If you want to separate it without distillation, centrifuge it if you have access to one.
Either way, I still don't comprehend what exactly you are wanting?
