- A model town with a population of 100000 people has a drinking water treatment plant. As an engineer, you are asked to design a sand filter system for the town. Determining: a) the total area of the filter, b) how many filter cells are needed if each filter cell has an area of 30 m2, c) depth of the sand, d) filtration rate, e) backwash rate if a rotary-jet-type surface wash is used, and f) the quantity of treated water used in backwash. Note: a) you need to fine a reasonable QDesign first; and 2) for backwash water quantity, you need to assume the min for the backwash first.

You are assigned to operate a drinking water treatment plant which has a capacity of 280 ML per day. If 5% of total raw water influent was used for filter backwashing without recycling and another 5% was lost due to sludge discharge and chlorine needs to be dosed is at 1 mg L-1 for the water after treatment, calculate the mass of chlorine that needs to be dosed each day at the treatment plant.

You are assigned to operate a drinking water treatment plant which has a capacity of 280 ML per day. The source water is from a river that contains a high concentration of dissolved organic carbon (DOC), (13 mg L-1) and has a high colour (60 HU) but where the alkalinity changes seasonally. In summer to winter the alkalinity is high (> 100 mg L-1 as CaCO3) and in spring after snow has melted in the mountains and the water flows...
