Abstract

This method is used for purification of waste and drinking water in the pulp and paper industry, etc. It provides a waste-free process and saves on materials and power. Following the method, ground raw kaolin, containing up to 14% of moisture, is mixed and homogenized with concentrated (over 92%) sulphuric acid. Later the mixture is decomposed in a sealed reactor at a temperature between 200 and 250 degrees C and vacuum up to 0.01 MPa for 45 to 75 minutes.
