Abstract

Process for enhancing the efficiency and decreasing the time and reagent demand of biochemical and/or physico-chemical decontamination technologies used to remove the dissolved and insoluble, organic or inorganic contaminating materials or combinations thereof from waters. The main feature of the process is that one or more artificial or natural materials containing at least 1 weight % crystalline alumino-hydrosilicate having a three-dimensional crystal lattice comprising a pore structure of molecular size, preferably one or more types of rock granules containing clinoptilolite, mordenite and/or other zeolites are added to the water to be treated or to the activated sludge, and macromolecules comprising a large number of positively charged groups, preferably cation-active polymers are bonded previously to the said materials by physical-chemical bonds so that free positively charged groups still remain on the bonded macromolecules. The bond between the solid material and the organic macromolecules is formed in a one- or two-step process.
