ABSTRACT:
A method for inhibiting the growth of microorganisms on sorbents selected from the group consisting of absorbents and adsorbents that are susceptible to undesirable microorganism growth when exposed to water containing such organisms, said method comprising passing water to be treated by said sorbent over brass particles prior to or concurrently with contacting said sorbent with said water, the contact with the brass particles being sufficient to inhibit the growth of microorganisms on said sorbent while not releasing more than 1 ppmw copper ions and 5 ppmw zinc ions into the effluent water. Also disclosed are related sorbent elements and pretreatment packets used in said method.
