A water treatment plant is designed for a constant flow rate of 3 MGD. The flocculation system consists of three tanks, each having a water depth of 10 ft and an average hydraulic residence time (HRT) of 30 min.
(a) Determine the dimension of each tank (i.e., width and length).

(b) Determine whether the flow through velocity is acceptable.

(c) The plant is planning to take one tank out of service for maintenance. Determine the increase in power requirement in the remaining two units to maintain the average velocity gradient (G) of 40 sec-1.

A municipal water treatment plant is designed to produce 20 million gallons per day (MGD) of potable water. The plant treats surface water using coagulation followed by sedimentation, filtration, and chlorination. Although the water is hard, it is not presently softened. The water is coagulated using a 30 mg/L dosage of alum (aluminum sulfate, Al2(SO4)3•14.3H2O, MW = 600). This chemical reacts in water to form Al(OH)3 as follows: Al2(SO4)3 + 6HCO3- → 2Al(OH)3(s) + 3SO4-2 + 6CO2 How many mg/L...

Discuss in detail how coagulation and flocculation are performed at a drinking water treatment plant. Describe how the optimum coagulant dose can be determined to treat fresh surface waters for drinking water supply. For removal of flocs from drinking water, when should settling basins be used and when should dissolved air flotation be applied? Why are GAC and PAC used in treating drinking water

A water treatment plant has three identical horizontal shaft flocculation tanks. Each tank is composed of three stages with size of 4 m depth, 14.1 m length and 15 m width. G value of each stage is 40 s-1, 30 s-1 and 20 s-1. Mean water temperature is 15°C (μ = 1.139×10-3). What are the power requirements for flocculation stages in a single flocculation tank. And Is the flocculation tank in an efficient way? ( Plant's average flow rate of...

Design rapid sand filters for a water treatment plant to treat a flow rate of 25 mgd. Use 1.5 for a peak factor. Consider the location of overflow troughs, freeboard, and pressure head of water. Assume that the length of the filters is 2 times the width and that the filtration rate is 3 gpm/ft2. Assume anthracite over sand with 1 ft gravel under media, top of water level during filtration is below troughs, and a 3 ft head drop...

8. A water treatment plant with a surface water intake source is being designed for a municipality that has a water demand of 18 million gallons per day (MGD). It has been determined that the maximum daily summertime water temperature is 20oC, and the minimum daily wintertime water temperature is 5oC. It has been determined that the design of the disinfection system must achieve 2.5-log credit for Cryptosporidium removal or inactivation. Ozone will be used as the disinfectant with a...

We designed the water flow rate to supply water to the increased population in New Jersey in 2020 and the trapezoidal canal that conveys the increased amount of water resources like Figure 2. The concrete-lined canal (n=0.015) is to have a B (bottom width) /yn (B/yn) of 2.0, 2H:1V side slopes and a velocity of 5.0 feet/s. The normal water depth is 3.75 ft and the longitudinal slope is 0.000825. 2.1. When the depth of flow at the gaging...

The Iowa City Water Treatment Plant and the University of Iowa Water Treatment Plant remove calcium hardness (Ca2+) by precipitating (making) CaCO3(s). If, after establishing equilibrium with CaCO3(s), the dissolved Ca2+ concentration is 10 mg/L and the pH is 10.5. a. What is the CO32- concentration in mol/L? b. What is the HCO3- concentration in mol/L? c. What is the alkalinity in mg/L as CaCO3?
