Question

(23) For each of the treatment technologies listed below, identify the key parameter(s) that is (are) central to the design of that particular technology. Please write the corresponding letters in the space provided next to the treatment technologies. Hint: 1) the number in parentheses next to the technology are the number of parameters you should find for each technology and 2) some parameters may not be used and some will correspond to several treatment options. 9.
