摘要

A method for processing fines materials generated as a by-product from the screening and washing of sand and gravel includes the steps of drying, pelletising and firing the fines materials to produce a ceramic material in the form of porous pellets which have enhanced properties for the removal of phosphorus and pathogens from wastewater.
