Consider a conventional surface water treatment facility with a maximum day design capacity of 35 million gallons per day (mgd)

Determine the configuration and dimensions for a 3-stage flocculaton system which uses horizontal paddle wheels. Determine the number of flocculations basins required. Determines the dimensions of each flocculation basin (width, length of each stage, total length, water depth, and freeboard), the detention time in each stage, the velocity gradient G in each stage, the blade configuration for the horizontal paddle wheel assemblies, and required motor horsepower for each stage. Clearly document any assumptions that you make.

A drinking water treatment plant is designed with three sedimentation basins in parallel. Each basin is designed with an overflow rate of 1,200 gpd/ft2 (gallons per day per square foot). (“In parallel” means that the flow is split evenly between the basins as shown below.) A. If the plant flow is 20 mgd (million gallons per day), find the plan area of each basin in square feet. B. Calculate the dimensions of the basins (length and width in feet) if...

4. (20 pts) A rapid mixing basin is designed to process 3.0 MGD of water. The basins will be square, and the depth is assumed to be 1.times of the width. Use a detention time of 30 s and velocity gradient of 750 s'. Two basins will be constructed each having a capacity to process exactly half the entire water flow. Determine: (a) Dimensions of the basin (L, W and H) (b) Power input (hp) (c) Rotational speed (rpm) of...

ENV Water Supply Flocculation tanks need to be sized to match three sedimentation basins 3.5 m deep and 6.0 m wide. The sedimentation basins each handle a flow of 5000 m/d, as will the flocculation tanks. The floc tanks will have two mixing sections with an overall average velocity gradient (G) of 35/s. The average velocity gradient-time (Gt) value has been set at 80,000. The paddles will be the wooden paddle-wheel type and will turn on a horizontal axis perpendicular...

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...
