A recent study investigated the use of natural zeolite as a microbial support media in wastewater treatment.
Using scanning electron microscopy (SEM), and other techniques, a team of researchers in Romania has concluded that natural clinoptilolite zeolite acts as an absorbent for pollutants and as a support material for the colonization of microbial communities. Overall the study indicates that there is a high potential for clinoptilolite in pollutant removal and microbial support.
