The existing permit does not have a liming flow for the facility. The current <br />permit is for maximum concentrations based on a flow of 7.0 mg/L which is <br />translated into mass loading (kg/d) discharge to the Cuyahoga River. A further <br />output of this analysis will be rated capacity of the secondary treatment system <br />based on control of filamentous growths which increase the SVI and reduce <br />aeration and clarification capacity. <br />Study Plan <br />The work plan to develop the information for the report will be divided~"nto <br />several tasks. These tasks are set forth with proposed objectives and the <br />approach. The August 1995 through February 1996 data would be employed in <br />the analysis. It is desirable to have two cold weather periods in the study. <br />Task 1. Definition of the influent flow and loadings to the primary clarifiers <br />and the primary clarifier effluent quality. <br />The secondary system capacity operating characteristics and its performance <br />are a function of the primary clarifier effluent loadings and its characteristics. <br />Reduction of the influent and effluent data quantifies the operating requirements <br />and may assist in the determination of the causative factors involved in periodic <br />prol~c growths of filamentous organisms. This information is also required in the <br />development of the mass balance and ultimate capacity of the wet treatment unit <br />operations. <br />The data would be presented graphically and in tabular form and discussions <br />provided as necessary to define critical factors. <br />Task 2. Reduction of the plant effluent data and analysis of results <br />The effluent data will be reduced to define the average and standard deviations <br />as well as environmental factors such as temperature and organic loading on the <br />2 <br />
