RELIABILITY AND REPRODUCIBILITY OF SMALL-SCALE BIOLOGICAL TREATMENT STUDY RESULTS Tzu-Shiung Hsu, Project Manager Patrick J. Lawler, Partner-in-Charge Lawler, Matusky & Skelly Engineers Pearl River, New York 10965 Andrew W. Edwards, Group Operations Manager Aware Inc./Southwest Houston, Texas 77024 INTRODUCTION The City of Glens Falls, New York is in the process of constructing a secondary wastewater treatment facility to upgrade its existing primary treatment plant. The new plant, described in the Wastewater Facilities Plan Amendment of June 1981 prepared by Lawler, Matusky & Skelly Engineers (LMS) [1], was originally designed to serve the population and industries of Glens Falls and to treat the pretreated industrial wastewater from the Ciba-Geigy Corporation (Ciba-Geigy) pigments facility. A pilot evaluation program was initiated and conducted by Ciba-Geigy and its consultant, the AWARE Corporation (AWARE), in January 1981 [2] to determine the compatibility of the Ciba- Geigy wastewater with joint secondary biological treatment and to develop process design criteria for the design of the treatment facility. Approval for the preparation of plans, specifications, and other documents required for construction was received by the City of Glens Falls in August 1981. Shortly after work began on the plans and specifications, the Village of South Glens Falls and Crown-Zellerback Corporation (CZ) expressed interest in participating in the project. After discussion, all interested parties agreed to investigate such joint treatment. Subsequently, LMS prepared a new Facilities Plan Amendment (completed in July 1982) and additional pilot evaluations in June 1982 [3]. The objectives of the latter were to investigate the compatibility of the CZ wastewater with joint secondary treatment and to develop technical information that could be used to modify the previously planned facilities to accept additional wastewater from the Village of South Glens Falls and the Crown-Zellerback Corporation. In its pilot plant evaluation LMS decided to include a control reactor into which only the Glens Falls and Ciba-Geigy wastewaters were fed. Thus, the combined waste of Glens Falls sewage and Ciba-Geigy pretreated waste was treated in both the AWARE study and the LMS study; these two evaluations were conducted independently at different locations on different dates using different sizes of pilot equipment and flow rates. This paper describes and summarizes the results obtained from the two studies on the same combination of Glens Falls/Ciba-Geigy wastewater. Side-by-side comparisons of pertinent process parameters, including organic loading (F/M), substrate removal kinetics, nitrification, oxygen utilization, solids production, solids-liquid separation, and nutrient requirements, are presented. The paper shows that the two studies, at markedly different scales of reactor size and flow rate, produced very similar results in terms of reaction parameters. It is hoped that this comparison will shed some light on the effect of equipment size on laboratory and pilot biological treatability studies. As an historical note, CZ and South Glens Falls withdrew from the project in October 1982. Therefore, only information from the two pilot evaluations on joint treatment of Glens Falls and Ciba-Geigy wastes was used in the final process design. 771
