Abstract | The complexity of waste treatment presents a never ending challenge to those in the field of design and operation. The tremendous growth of this country has created serious waste treatment problems, which pose a serious threat to our water resources and our health. A reflection of this growth is the addition of thousands of new industries each year, many of which present waste disposal problems. In many cases the solution to disposal is combined industrial and municipal waste treatment. In some instances, the effect of an industrial waste on standard sewage treatment facilities is not known. Such a waste is produced in the manufacture and use of "ammonium perchlorate." Ammonium perchlorate is an important oxidizer used in the manufacture of rocket propellants in the missile industry. This study presents the ability of the trickling filter process to remove BOD(Biochemical Oxygen Demand) from wastes containing varying concentrations of ammonium perchlorate. "Equivalent" rotating tube units simulating the stone trickling filter were utilized for laboratory studies, and an experimental plan was formulated to determine the effect of the perchlorate waste on BOD removals. It was found that the rotating tubes were capable of BOD reductions of approximately 88.5 per cent when treating synthetic sewage. The BOD removals were not significantly changed by shock loading the tubes with concentrations of 40, 100, 400, and 900 mg/1 perchlorate ion added in the form of ammonium perchlorate. It was also determined that there was no biological degradation of the perchlorate ion experienced in treatment. The aforementioned results were based on a determined residence time of one minute and thirty seconds. |
