Wastewater treatment

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of pending U.S. patent application Ser. No. 12 / 592,699, filed on Dec. 1, 2009, titled Treatment of Wastewater, which claims priority to expired U.S. provisional application 61 / 200,958, filed Dec. 5, 2008, titled Treatment of Wastewater.FIELD OF THE INVENTION[0002]This invention relates generally to wastewater treatment and, more specifically to treatment of wastewater to kill microorganisms therein.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0003]NoneREFERENCE TO A MICROFICHE APPENDIX[0004]NoneBACKGROUND OF THE INVENTION[0005]An increase in the consumption of water for all types of uses as well as the quest for a cleaner environment generates a need to recycle all types of water including wastewater. Wastewater, which may be either residential or industrial wastewater, may be in various conditions and may include human waste, food scraps, oil, soaps and chemical. Household wastewater ...

AI Technical Summary

Benefits of technology

[0010]In another example the invention includes method of killing microbes in wastewater by adding a source of biocidal metal ions to the body of wastewater together with a compound containing a hydantoin ring to enhance the biocidal metal ion concentration to a level effective to kill the microorganisms in the wastewater.

Problems solved by technology

While biocidal metals are effective in killing microorganisms one of the difficulties with killing microorganisms in wastewater with biocidal metals is that in the presence of wastewater the solubility of the biocidal metal ions may not be sufficiently high so as to effectively kill the microorganism in the wastewater.

Conditions within the water storage can not only pollute the water with solids but also can cause growth of harmful microorganisms as well as transfer of harmful microorganisms from one geographical location to another geographical location as a ship picks up ballast water in one port and discharges the ballast at another port or at sea.
