used inenvironmental engineering for numerous applications, especially for removing contaminantsfrom water and air. Environmental engineers typically quantify the mass of adsorbate per massof adsorbent (adsorption density, q) as follows. x �Co − Caq �V q= = M Mwhere,Co = initial aqueous concentration (mg sorbate/L)Caq = equilibrium aqueous concentration (mg sorbate/L)V = volume of solvent (L)M = mass of sorbent (g)When modeling and designing adsorption treatment processes, the adsorption density is typicallygraphed as a function of the adsorbate’s equilibrium aqueous concentration at a constanttemperature; this

Studies of these open systems found that energy is conserved across thecontrol surface for open systems as well as closed systems.

visualize pipe flow also in terms of mass balance andintroduces how the continuity equation (Q=V×A) plays a pivotal role in understanding what isoccurring throughout the system. Since mass is conserved, as water moves through a pipesystem (assuming no leaks), mass balance parameters will dictate that the flowrate must remainconsistent even as changes of A and V occur. As Q is increased, we must increase the velocity offlow and/or the size of pipe. For a specified Q, flow can be increased by reducing pipe size.Conversely, velocity can be decreased by increasing pipe size. Essentially, the continuityequation is just the conservation of mass in terms of volumetric flow. Mass does not appear inthe equation though because water is an incompressible

of bacteria, i.e., methanotrophs. The laboratory study is conducted as follows:in sterilized serum bottles, methanotrophic bacteria in the exponential growth phase areinoculated in a Milli-Q water-based medium containing nitrate, other key nutrients (P, K, Na,Mg, Ca, etc.), and selected trace metals. The primary substrates, methane and oxygen, are thenintroduced and each bottle is placed on a shaker-table for incubation. Gas samples areperiodically withdrawn from the headspace of each bottle and manually injected into a gaschromatograph to measure the concentrations of methane, oxygen, and carbon dioxide. Thisallows students to monitor the amount of substrates consumed and the amount of end productproduced at different time points. Students

One, StudentQ, explained, “I would prefer exams over presentations, but I like the researchpapers”.Student Q expressed displeasure with the knowledge gained from the researchassignment: These papers/presentations, as far as individual research is concerned, do not give us a full scope of the reg(ulation)s.

These random fluctuations willdisperse the pollutant away from the plume centerline, resulting in a normal or Gaussiandistribution of concentrations in both the vertical (z) and crosswind (y) directions.

Malcolm Field and others have applied RTD theory to describing tracerstudies in karst. This is the basis for the Q-Tracer Program developed by USEPA formathematical modeling the hydraulic characteristics of karst systems based on tracer study data.TSU has extended this theory to mathematically describe biodegradation of contaminants in
