A large, aerated lagoon is to be used to treat wastewater from a small community. The wastewater flow is 0.05 m³/s. The influent (input) wastewater contaminant concentration is 250 mg/L. The required effluent (output) concentration is 30 mg/L. It was found that the waste degrades according to first order kinetics. The degradation coefficient (k) for the reaction is 0.52 d'. You may assume that the lagoon is completely mixed and that conditions in the system are at steady state. Determine: a) The required volume of the lagoon b) The hydraulic detention time of the lagoon

Researchers working on a Lake measured the following in the anoxic bottom waters:[Fe2+] = 100 μM and [S2-] = 50 fM (femtomolar). The formation of FeS(s)Fe2+ + S2- is an important controlling reaction for the solubilityof Fe(+II) under anoxic conditions. In this lake, the temperature at the bottom is about 10°C inthe summer.a. Calculate Kideal for this reaction, ignoring non-idealities.b. Correct K for the temperature at the lake bottom.c. Is the lake water at equilibrium with FeS(s) in the aquifer? If not, given more time,would more solid dissolve or precipitate?

An ocean outfall diffuser that discharges treated wastewater into the Pacific ocean is 5,000 m from a public beach. The wastewater contains 105 coliform bacteria per milliliter (coliform /mL). The wastewater discharge flow rate is 0.3 m3/s. The coliform first-order death rate in seawater is approximately 0.3 h-1. The current carries the wastewater plume toward the beach at a rate of 0.5 m/s. The ocean current may be approximated as a pipe carrying 600 m3/s of seawater. Determine the coliform concentration at the beach. Assume that the current behaves as a plug-flow reactor and that the wastewater is completely mixed in the current at the discharge point.

A + B = A-B The formation of non-covalent complexes in water is a fundamental reaction in bioorganic chemistry. For reactions where A or B (or both) are proteins, kon is often in the neighborhood of 1.00 x 10° M-'s-1 (an approximate value for the diffusion limit). Using this value of kon, determine the half-life in seconds of the following common biochemical complexes (A-B) obtained from an antibody which binds a viral protein with Ka = 5.00 × 10-7 M. t12 =
