Abstract: Completely- and partially-suspended lagoon cells are defined and their use in dual-power level, multicellular systems is discussed. A procedure is presented for the design of such systems on a rational basis using biokinetic coefficient data. Factors relating to the performance of these systems with respect to soluble BOD5 and suspended solids in the effluent are also discussed. Special attention is paid to cell size and number, power requirements both for solids suspension and oxygen demand, benthal solids decay, and sludge accumulation. A design example is given. It is concluded that further research and performance data derived from systems designed by the procedure are needed for a better evaluation of the parameters used and to test the assumptions made in applying the procedure.
