Specifications include, but are not limited to: The District is a wholesale provider of treated water to Salt Lake City Public Utilities Department, Sandy City Public Utilities Department, and others. The District owns and operates two (2) water treatment plants, the Little Cottonwood Water Treatment Plant (“LCWTP”) and the Point of the Mountain Water Treatment Plant (“POMWTP”), (collectively called the “Treatment Plants”). The Treatment Plants have full conventional treatment. Ferric chloride is the primary coagulant at the LCWTP. It may be used at the POMWTP in the future. I. FERRIC CHLORIDE PURPOSE Ferric chloride is used during the treatment process to create a floc which then helps remove organic carbon, turbidity and other unwanted components from the water. Ferric chloride is a key chemical component of the water treatment process. II. FERRIC CHLORIDE STANDARDS Product shall meet the NSF/ANSI Standard No. 60 for Drinking Water Treatment Chemicals - Health Effects and AWWA Standard B407 Specifications include, but are not limited to, the following: 1. Impurities: the liquid ferric chloride shall contain no substances in quantities capable of producing deleterious or injurious effects on the health of those consuming the water or that would otherwise render the water unfit for public use after having been properly treated with liquid ferric chloride. 2. Drinking Water Standards: the liquid ferric chloride, when fed at rates required for water treatment, shall not impart to the water any contaminants that would cause established drinking water standards to be exceeded when combined with the concentration of such contaminants which may already be present in the water to be treated. 3. Metals: All products purchased under this contract shall be free of metals to the extent described in NSF/ANSI Standard No. 60. III. FERRIC CHLORIDE TECHNICAL SPECIFICATIONS 1. Concentration: 28% to 47%, higher concentrations are preferred. 2. Specific Gravity: 1.3 to 1.5. 3. Total Iron as Fe: 9.6% to 16.2%. 4. Percent of total iron in a ferrous (Fe2+) state: not to exceed 2.5%. 5. Free acid, expressed as HCl: not to exceed 1.0%. 6. Total insoluble matter in solution: not to exceed 0.2% by weight.
