The purpose for the preceeding development program was to design a mobile denitrification pilot plant that could be used in a number of DOE and commercial nuclear fuel cycle operations to test the applicability of this biological denitrification process to their individual nitrate wastewaters. The results indicate that the scale-up of the bioreactor from 5 cm i.d. to 10 cm i.d. is directly proportional. The tests with the single and dual 10-cm-i.d. by 6-m tall bioreactors corresponded satisfactorily with the 5-cm-i.d. bioreactor empirical curve of nitrate concentration vs. bioreactor length. Therefore, we have a basis for predicting the performance of our mobile pilot plant. The mobile pilot plant will contain two 20-cm-i.d. by 7-m long bioreactors operated in series. For near-zero NO/sub 3//sup -/ effluent (5 to 10 g/m/sub 3/), the feed will have a maximum concentration of 4000 g/m/sup 3/ and will be introduced at a flow rate of 16 liter/min. The temperature will be regulated between 22 and 30/sup 0/C. 13 figures, 3 tables.
