TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Process: The runoff disposal process further includes analyzing the chlorine residual in the runoff, and de-chlorinating the runoff with a de-chlorinating agent; circulating the runoff through a filtration bag; collecting samples of the filtered runoff and the collected solids; testing the liquid runoff and the solids for contaminant concentrations as required by federal, state and local regulations; lowering the contaminant concentrations to levels acceptable for disposal under local regulations; disposing the treated runoff into the storm sewer; diverting the treated runoff into a backwash water recycling stream of the drinking water facility; diverting the collected solids to a landfill or hazardous waste collection site in accordance with federal, state and local regulations; and additional step(s) from removing dissolved heavy metal contaminants, de-chlorinating the runoff, collecting particulates removed during the cleaning process and accumulated as sediment in the cleaned facility, removal of suspended particulates from the treatment solution through settling or filtering processes, removal of organic/biological contaminants, disinfecting the runoff prior to neutralization, or recycling the runoff prior to neutralization for continued use in the cleaning process until a predetermined turbidity of the treatment fluid is reached at which the runoff is treated for disposal. The runoff is collected at the bottom of the treated drinking water facility.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The pH neutralizing agent is sodium hydroxide (liquid or dry), sodium hydroxide solution, calcium hydroxide, sodium carbonate, magnesium hydroxide, and/or potassium hydroxide (liquid or dry). It is preferably 25% caustic soda.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Component: The holding facility is the treated drinking water facility.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The de-chlorinating agent is sodium thiosulfate, sodium bisulfite, sodium sulfite, sodium bisulfate, ammonium thiosulfate, ammonium bisulfite, ammonium chloride, and/or ascorbic acid.
