Wastewater from Taman Cenderawasih is treated through a bio tower. These are the data related to the bio tower:

Flow rate	=	20 000 m³/day
Minimum temperature of the area	=	34^◦C
Medium height	=	2 m
Influent BOD	=	300 mg/L
Effluent BOD	=	20 mg/L
Recirculation flow rate to the tower	=	35 000 m³/day
Wastewater treatability constant	=	0.09 min^-1 at temperature 20^◦C
Medium coefficient	=	0.5

Compute:

Ratio of recycled flow to the influent flow
Hydraulic loading (m³/m².min)
Volume of the medium needed

A municipal wastewater treatment plant discharges 20,000 m3/d of treated wastewater to a stream. The wastewater has a BOD5 of 30 mg/L with a k1 of 0.23 d-1. The temperature of the wastewater is 20 oC, and the dissolved oxygen is 2.0 mg/L. The stream just above the point of wastewater discharge flows at 0.65 m3/s, has a BOD5 of 5.0 mg/L, and is 90% saturated with oxygen. The temperature of the stream is also 20 oC. After mixing, the...

A tray tower provides 10 equilibrium stages for stripping ammonia from a wastewater stream by using a countercurrent air stream at 1 atm and 300 K. Assume that the inlet water concentration is 0.2 mole% ammonia, the inlet air does not have ammonia, and 1 SCM (standard cubic meter) of air is fed to the tower per kilogram of wastewater. Here the equilibrium curve is linear with m= 1.414. (a) Estimate the outlet molar concentration in the exit water. (b)...

A factory disposes 1.1 m3/s of treated industrial wastewater into a river. The wastewater has an ultimate biochemical oxygen demand of 25 mg/L and dissolved oxygen of 2 mg/L. Just upstream of the wastewater outfall, the river has a flow rate of 10 m3/s, ultimate biochemical oxygen demand of 6 mg/L, and oxygen deficit of 2 mg/L. At the river temperature, the saturation concentration of dissolved oxygen is 9 mg/L. The deoxygenation coefficient is 0.19 d-1 and reaeration coefficient is...

A wastewater plant needs to reduce the methane content in water in a stripping tower to 0.3 mol %. The liquid stream is entering the tower with a flow rate of 200 mole/h and contains 0.8 mol % methane. The tower uses pure air for stripping and its temperature and pressure are held constant at 300 K and 1 atm, respectively. The equilibrium relation for methane in the air-water system is ? = 1.2?. a) Find the minimum vapor flow...

A domestic wastewater with a flow of 1700 m3 / day will be treated in a biological treatment plant. Wastewater pre-settling tank effluent BOD value is 350 mg / L. If the volume of the biological reactor (ventilation reactor) is 500 m3, do you prefer a fully mixed or plug-flow reactor? Please explain the reasons.
