A dog food processing plant generates 0.015 m3/s of wastewater, which is treated using an activated sludge plant.  The discharge permit allows 30 mg/L BOD5 in the effluent.  The average BOD5 of the raw wastewater before primary settling is 1,400 mg/L.  The primary settler removes 35% of the BOD5.  The aeration tank is 200 m3 in size.  The mixed liquor has a concentration of 2,000 mg/L.  The yield coefficient is 0.50 mg MLVSS/mg BOD5 and kd = 0.06 d-1.  Determine:

  1. The aeration period (hr)
  2. F/M ratio (mg BOD5/(mg MLVSS*d)
  3. Solids retention time (d)
