Design a rapid mono-media sand filter for a plant that has a design flow rate of 120 MGD Filter Box Surface Dimensions. Design a roughly square filter box that will contain two filtering units and a 12-feet wide drain gullet. Determine: a) Length of each filter box (ft) b) Width of each filter box (ft)

An oil company has drilled a hydraulic fracturing well near your microbrewery in Anytown, U.S.A. It stores the wastewater in a holding pond on site until proper disposal techniques can be implemented. On October 10 at 1200 hours, the company notified the town that they have detected a leak in the holding pond and the brine water may have entered the water table aquifer. Meanwhile, the Anytown Beer Brewery is happily making "Anytime Bitter IPA", known by its slogan "Anytime you feel bitter, have an Anytime Bitter IPA". The source of water for their product is a production well that taps the water table aquifer at a rate of 65 gpm. The monthly water quality testing is due to occur on October 16 at 1600 hours. Using the information provided, determine if the brine will show up during the inspection, what additional contaminants may exist, and possible soil remediation techniques to solve the problem. 1) Figure 1 shows a contour map of the water table around the well at the brewery.…

Your client has request that you design a cloth media disc filter for the tertiary filter in a new plant. The flow is 3.2 million gallons per day (MGD). The Division of Drinking Water has approved the nordic CMF(5 gpm/sf). The manufacture indicates that the filter disc diameters are 2.4 m (8 ft). How many discs will you need assuming 1 disc will be out of service?

Dechlorination contact tank (Wastewater Treatment) An activated sludge plant has a design flow (average daily flow) of 11 MGD.  Determine dimensions of dechlorination tank.    The design parameters: use 1 tank.   detention time = 30 sec, depth = 10 ft, rectangular tank:  L = 4 W. use maximum hourly flow (3 * Average design flow)
