A bio-tower composed of a modular plastic medium of 6 m is used as secondary treatment component in a municipal wastewater treatment plant. Flow from the primary clarifier is 25000 m³/day with 200 mg/1 BOD. The treatability constant is 0.06 per min. To produce an effluent with a soluble BOD of 20 mg/1, the surface area as per Eckenfelder (coefficient related to medium is 0.5) is approximately:
6. A tertiary treatment plant treats a municipal secondary effluent and is to employ fixed-bed carbon adsorption columns. Parallel treatment using two rows of two columns in series (in other words, a total of four columns) will be used. From batch-type slurry tests it has been found that 0.42 g COD/g carbon is adsorbed when Ce = Co. Pertinent data are as follows: flow = 5700 m³/d, COD in feed to carbon columns = 20 mg/L, contact time function based on an empty carbon bed = 30 min, and unit liquid flow rate= = 4.4 L/s-m².

Example (Activated Sludge Process) - Completely Mixed with Recycle A completely mixed activated sludge process, treating a municipal wastewater, has a primary clarifier effluent BOD, of 135 mg/L. The design MLSS is 3590 mg/L, and the MLVSS is 80% of the MLSS. The plant permit is for an effluent BOD, of 20 mg/L and 20 mg/L suspended solids. The effluent suspended solids have a BOD, of 0.65 mg BOD, / mg suspended solids. The underflow solid concentration (MLVSS) is 10,000 mg/L. If umax = 3.0 day, Ks 60 mg/L, Y= 0.50 mg MLVSS / mg BOD, removed, ka= 0.1 day, and the influent flow is 0.25 m/sec, determine the following: 1. The required reactor detention time, 0. 2.
