A radioactive waste from a clinical laboratory contains 0.2 μCi (microcuries) of calcium-45 (45Ca) per litre. The reaction rate constant is 0.005/day. The radioactive calcium waste is treated in a pipe that is 200 m until it reaches below the maximum acceptable radioactivity of 0.01 μCi/L. Assume the pipe approximates a plug flow reactor. (c) Calculate the lineal velocity (in m/h) of the radioactive calcium waste in the pipe so that the radioactivity is less than 0.01 μCi/L at the...

I could not solve part C. A radioactive waste from a clinical laboratory contains 0.2 μCi (microcuries) of calcium-45 (45Ca) per litre. The reaction rate constant is 0.005/day. The radioactive calcium waste is treated in a pipe that is 200 m until it reaches below the maximum acceptable radioactivity of 0.01 μCi/L. Assume the pipe approximates a plug flow reactor. (b) How long (in days) does the radioactive calcium waste need to be in the pipe before the outflowing waste...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
