Activated coal is used in absorption processes as it is one of the most effective methods of air purification from toxic gases and odors. It is also used for water purification from toxic gases and odors. It is also used for water purification by particles and pollutants, such as ozone, chlorine and its derivatives, ionic surfactants, solvents, pesticides and organic micropollutants. Also in this case we are able to engineer and build fixed stations or filters, filtration skid, in containers or trailerized.
