g The Jar test is implemented as a venue to identify the optimum coagulant dose for Alum (as decsribed in section 6-2 of the textbook. The Jar Test identifies the optimum alum dose as 25 mg/L. Determine the alkalinity of the raw water (before alum addition) if the water maintains an alkalinity as 45 mg/L as CaCO3 after sedimentation of the solids.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
