A sewage treatment plant for a town with 120000 population and water average temperature of 20'C should be designed. You are asked to design a coagulation/rapid mixer and a flocculation tank with horizontal shaft paddle. The jar tests suggest average G-value of 30 (m/s)/m, minimum water residence time of 1500 seconds and GT value from 55000 to 90000. The flocculation tank should include 3 compartments with similar compartments' geometry aspects separated using baffles partitions. The width of each flocculation tank should not exceed 7 meters due to some constraints highlighted by the project's mechanical engineers about the maximum length of each shaft. Determine: 1- The volume and dimension and power requirement of the cylindrical rapid mixer 2- The flocculation tank dimension 3- Required power for each flocculation mixer 4- The paddle wheel dimension 5- Rotational speed of each mixers (Check if the speeds are acceptable) 6- Baffle size and distribution 7- Write about any ethical concerns about your design especially if you decide to directly build the tank and mixers
