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.
Claims20
A method for treatment of greywater containing solid pollutants using a single biocidal component comprising:
- removal of the solid pollutants from the greywater;
- adding a concentration of a biocidal component to the body of greywater after removal of the solid pollutants to kill microorganisms in the greywater to render the water suitable for human consumption;
- and
- maintaining the effectiveness of the biocidal component in the greywater by adding a biocidal ineffective compound having a hydantoin ring therein to the greywater to increase the concentration of soluble biocidal component in the greywater to sustain a standard plate count at 35 Degrees Fahrenheit of less than 200 colonies per milliliter.
A method of treating a body of wastewater using a single antimicrobial agent to kill microorganisms therein by increasing the effectiveness of an antimicrobial agent comprising the steps of:
- adding a level of a biocidal metal to the body of wastewater to kill microorganisms in the wastewater to render the water suitable for human consumption maintaining a biocidal metal level of between 1.0 ppb to 3.0 ppb in the body of water by adding a source of biocidal metal to the body of wastewater to generate biocidal metal ions in the body of wastewater;
- and
- adding a biocidal ineffective compound containing a hydantoin ring to the body of wastewater;
- forming soluble complex of at least the biocidal metal and the biocidal ineffective compound in the wastewater wherein the soluble complex of biocidal metal inhibits the formation of insoluble metal compounds to maintain the effectiveness of the biocidal component in the wastewater to sustain a standard plate count at 35 Degrees Fahrenheit of less than 200 colonies per milliliter.
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.
