Consider the single stage trickling flter plant from the solutionin Example 9.1. The use of a single stage fIlter produced a planteffciency of about 75%.

Primary clarifcation removes 30% of the BOD5.The filters are each 12 m in diameter and 1.5 m in depth. The directrecirculation ratio for each stage is 2.0. Wastewater temperature is20°C. Calculate the second stage hydraulic loading rate, organicloading rates, effuent BOD5 concentration, and overall plant effIciency.

The wastewater from a manufacturing treatment plant is discharged to a municipal 'treatment plant for processing with domestic wastewater. The characteristics of the wastewater from the manufacturing treatment plant are 3500 mg/l BOD, 4500 mg/l SS, 70 mg/l nitrogen and 2 mg/l phosphorous. The characteristics of the domestic wastewater are 350 mg/I BOD, 285 mg/I SS, 50 mg/lN and 11 mg/I P. If the required BOD/N/P weight ratio is 100/5/1, what is the minimum quantity of domestic wastewater required per 1000 gallons of manufacturing wastewater to provide adequate nutrients for biological treatment and the concentration of SS in the combined wastewater?
