10. Consider a lake with 10 m' of surface area for which the only source of phosphorus is the effluent from a wastewater treatment plant. The effluent flow rate is 0.4 m/s, and its phosphorus concentration is 10 mg/L. The lake is also fed by a stream have 20 m/s flow with no phosphorus. If the phosphorus settling rate is estimated to be 10 m/yr, estimate the average phosphorus concentration is the lake. What level of phosphorus removal at the...

1. In 1970, the total phosphorus (TP) load to Lake Erie was 18.150 tonnes/year (where tonnes or metric ton = 1,000 kg). The surface area, volume, and outflow from Lake Erie are given as 25.2 x 10 m² 468 x 10 m, and 182 x 10 m yr, respectively. Based on previous evaluations, the total phosphorus is removed from the lake with an apparent settling rate of 16 m/yr. a. Draw a diagram and write the mass balance equation for...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
