NOVELTY - Making a sintered nanoparticle compound involves providing a zeolite; providing a silver nitrate (AgNO3); providing a silver dioxide nanoparticle (Ag2O np); providing a graphene; combining a core element of the zeolite with a solution of AgNO3 and/or Ag2O np; and mixing the solution to provide equal distribution, where the zeolite core is impregnated with the AgNO3 and/or Ag2O np. USE - Method for making sintered nanoparticle compound used in enhanced filtration systems and/or pressurized wastewater filtration plants. ADVANTAGE - The method provides effective and cost-efficient treatment compositions, and shows sterilization and anti-pathogenic properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of making an enhanced granulated activated charcoal (EGAC) compound, which involves providing a granulated activated charcoal; providing a silver nitrate (AgNO3); combining the granulated activated charcoal with a solution of AgNO3 and mixing to uniformly combine the granulated activated charcoal with the AgNO3 to form a granulated activated charcoal and AgNO3 composite; providing a silver dioxide nanoparticle (Ag2O np) and mixing it with the granulated activated charcoal and AgNO3 composite; and placing the granulated activated charcoal with AgNO3 and Ag2O np in a negative pressure autoclave.
