| Abstract | Four small outdoor reactors, a predator infested outdoor pond, and numerous indoor systems were designed, constructed and operated to provide data describing the kinetics aspects of algal systems used as wastewater treatment schemes. The studies included determinations of: The kinetics of ammonia-nitrogen as a growth limiting factor; The effect of nutrients in wastewater effluents on algal growth; Suggested designs for both indoor and outdoor growth reactors; and Predator-prey relationships in outdoor algal systems. Specific growth rate data for nitrogen were quite consistent, allowing the use of the maximum specific net growth rate as an extremely reliable parameter of system operation. Other studies demonstrated that permissible dilution ratios for waste water discharges into receiving waters can be formulated empirically. Design and operational information of various systems is presented, as well as preliminary bioassay results on the microbial populations of algal ponds. (Author) |
