Problem 5- Estimate the thickness of the diffuse double layer of an illite clay particle suspended in seawater assuming that the assumptions of the Gouy-Chapman theory of the double layer apply. The cation exchange capacity of the clay is 25 meq/100 g. There are 500 ppm of salt dissolved in the seawater, which may all be assumed to be NaCl for this analysis. The specific surface area of the clay is 80 m²/g. The exchangeable cation on the clay is sodium. Assume that the dielectric constant of the solution is 80 and that T= 15°C.

A wastewater treatment plant (WWTP) releases effluent into a stream with mean depth 2 m and mean velocity 0.5 m/s. The BOD concentration at the WWTP is 15 mg/L, and the oxygen deficit is negligible. The de-oxygenation rate in the stream is 0.8 d-1 and the re-aeration rate is 1.2 d-1. a) Calculate the BOD concentration 20 km downstream from the WWTP. b) Calculate the D.O. deficit 20 km downstream from the WWTP. c) Define "critical distance" in the context of river pollution modeling and compute it for this example.
