Wastewater treatment
First Claim
1. A method for treatment of wastewater containing solid pollutants comprising:
- removal of the solid pollutants from the wastewater;
killing microorganisms in the wastewater after removal of the solid pollutants by adding a biocidal component to a body of wastewater; and
enhancing the effectiveness of the biocidal component in the wastewater by adding a compound containing a hydantoin ring to the wastewater, which may or may not have any antimicrobial properties, to thereby enhance the effectiveness of the biocidal component by increasing the solubility of the biocidal component in the body of wastewater.

Abstract
An antimicrobial method of treating wastewater and a wastewater antimicrobial dispenser containing an antimicrobial agent for treating a body of wastewater to kill microorganisms by increasing the concentration metal ions therein. The antimicrobial method includes the step of increasing the effectiveness of the biocidal component in the body of wastewater to thereby lessen the need for a supplemental biocide by adding a compound containing a hydantoin ring where the compound containing a hydantoin ring may or may not have any antimicrobial properties. The antimicrobial agent including a source of biocidal metal ions and a compound containing a hydantoin ring where the antimicrobial agent may be a powder, a liquid a solid or combinations thereof.

10. A method of treating a body of wastewater to kill microorganisms therein by increasing the effectiveness of an antimicrobial agent comprising the steps of:
-
adding a source of biocidal metal to the body of wastewater to generate biocidal metal ions in the body of wastewater; and adding a compound containing a hydantoin ring to the body of wastewater, where the compound containing a hydantoin ring may or may not have any antimicrobial properties, to interact with the source of biocidal metal to increase an availably of biocidal metal ions in the body of wastewater. - View Dependent Claims (11, 12, 13, 14, 15)

16. A wastewater antimicrobial dispenser for killing microorganisms in a body of wastewater comprising;
a dispenser containing a source of biocidal metal ions releasable into the body of wastewater to generate a santizing level of biocidal metals insufficient to kill the microorganisms in the body of wastewater and a compound containing a hydantoin ring releasable into the body of wastewater wherein the compound containing the hydantoin ring increases the antimicrobial level of biocidal metal ions in the body of wastewater to a biocidal level sufficient to kill microorganism in the wastewater. - View Dependent Claims (17, 18, 19, 20)
