Essay Example on Wastewater is any water that adversely affects the quality of human Health

The concentration in effluent is X_a e rate Qe The concentration of microorganisms of sludge wasting from recycle line is X_a w at flow rate Qw b Structure c Advantage Increased concentration of microorganism in the reactor Increased the volumetric reaction rate Much smaller reactor volume is required biomass is captured and built up to a much higher concentration than normal CSTR decrease reactor volumn Smaller cost of the settler and recycling system II MATERIALS AND METHODS 1 Material Wastewater From municipal wastewater The main characteristic of this wastewater is the high amount of total ammonia nitrogen contained All collected samples were stored at 4 C after collection until required for analysis CSTR system with settling and cell recycling 2 Methods Select an appropriate volume for a CSTR reactor with settling and recycle to achieve an average 90 percent nitrification of ammonium in a municipal wastewater following biological treatment for BOD removal IV CONCLUSION The average removal efficiency of NH4 N 99 5 is therefore much larger than required providing another level of safety in the design for system In this case as with most actual designs the volume reactor tends to be more governed by the reliability considerations rather than considering the removal efficiency
