Benefits of technology

[0008]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 toget

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.

example

[0025]Silver bromide was initially prepared from a saturated sodium bromide solution, combined with silver nitrate in solution. The yellow precipitate, silver bromide, was than purified by filtration and washing. Additionally, the solid was allowed to dry before use.

[0026]A buffer system having a pH of 7.41 was prepared by adding Fisherbrand® potassium phosphate monobasic-sodium phosphate dibasic buffer to 2 Erlenmeyer flasks filled with 1000 mL of purified water. The first flask was treated with 1.12 grams of 5,5-dimethylhydantoin (DMH) and marked solution “C” (with DMH) and the second flask was left untreated and marked solution “D” (without DMH) for control. In regards to the 5,5-dimethylhydantoin (DMH), the 5,5-dimethylhydantoin (DMH) comprised 97% reagent grade was obtained from Aldrich® (CAS No. 77-71-4, Cat. No. D161403-1KG).

[0027]After the initial set-up, approximately 0.10 grams of dried silver bromide was introduced into a dialysis tubing (Fisherbrand®, 45 mm, MWCO 12,000-...

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 claims priority from U.S. provisional application 61 / 200,958 filed Dec. 12, 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 DEVELOPMENTNoneREFERENCE TO A MICROFICHE APPENDIXNoneBACKGROUND OF THE INVENTION[0003]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 generally comes from household appliances, bathtubs, showers and toilets. Wastewater that is heavily polluted is often referred to as black water and hous...
