Concentration equation

The concentrations of the solutions may be calculated by using the dilution equation. Concentrations may then be converted to moles by multiplying the concentration by the liters of solution. This procedure applies to buffer components or any reactant species. 

As noted in Eqnation (15.100), the design is based on the heterotrophs with the mean cell retention of the nitriflers being the one used. Thus, the process is considered as simply the normal activated sludge process, with nitrihcation considered incidental to the scheme. Also, note that in the equation, concentrations are found both in the numerator and the denominator. This means that any unit of measurement for concentrations can be used. 

Rearrange the standard equation concentration = mass in grammes divided by (RFM X volume), so that volume is on its own on the LHS. 

We consider dilute solutions and equate concentration and activity ... 

These simplified equations concentrate on the main features of the reaction and explain most of the observations made. However, the actual mechanism also includes the equilibrium constants of each reaction step, for most of them are reversible [15].

Remember Products over reactants each concentration is raised to a power equal to the corresponding coefficient in the chemical equation concentrations are multiplied, never added. 

Finally in this section, the errors introduced by equating concentrations and activities throughout this book will be examined. For each ion in solution, the activity is defined by ... 

The discussion, however, would suggest an importance to the errors introduced by equating concentration and activity, which is not always confirmed in practice. This is because one is often concerned with a ratio of activities where the activity coefficients tend to cancel. Also, in some applications of electrochemistry the concentration of electroactive species is low compared with that of the total electrolyte. 

The increase in metal ion concentration in the strip from the treated water is reported as the concentration factor. The concentration factor is determined from the following equation Concentration factor = [M" ] in strip / [M" ] in original solution. The emphasis of these tests was metal ion separation therefore, the concentration factors reported here are far from optimal. The concentration factors for the WP-1 strip were Cu = 20, Al = 17, and Zn = 5. The concentration factors for the WP-2 strip were Cu=19, Al = 3, and Zn = 3.
