What type of binder is user for making activated carbon briquettes for water purification? Answered
Hello everyone, I am trying to make a water purification device which needs to have compressed activated carbon filter. I am facing the problem of binding the charcoal dust together so that it does not come out when contacted with water. I tried making the briquettes with starch but it is water soluble. I have read some papers on binding the charcoal using extrusion process but could not find what exactly is the binder used. Here the binder should not cover the surface area of the carbon particles as well.
I am looking to find here, what is the binder used and how is it used, i.e, ratios. I want to make something like this in the image which is water insoluble.
