A bar screen is used to treat 10 MGD of menicipal wastewater. The vertical bars are 1.27 cm wide and 3.8 cm deep. The minimum allowable spacing for the bars is 2.4cm. The appoach channel carries the water at velocity of 0.381 m/s and is 1.07 m wide and 1.37 m deep.  1- detrmine the number of bar and spacing that should be used. 2- calculate the head loss through screen when it is clean (m).  3- it's estimated that the screen will remove 227 kg (wet basis) of screenings ber milion gallons of water treated. What will be the daily accumulation (kg and m^3) of the screening if the density of screening 100 kg/m^3.

A bar screen is used to treat 10 MGD of menicipal wastewater. The vertical bars are 1.27 cm wide and 3.8 cm deep. The minimum allowable spacing for the bars is 2.4cm. The appoach channel carries the water at velocity of 0.381 m/s and is 1.07 m wide and 1.37 m deep. 
1- detrmine the number of bar and spacing that should be used.

2- calculate the head loss through screen when it is clean (m). 

3- it's estimated that the screen will remove 227 kg (wet basis) of screenings ber milion gallons of water treated. What will be the daily accumulation (kg and m^3) of the screening if the density of screening 100 kg/m^3.
