title: Effect of hard detergents on algae in a high-rate-oxidation pond.
abstract: Regular concentrations of hard detergents in domestic wastewater do not affect algal growth in a high-rate-oxidation pond. The addition of nonionic hard detergent at concentrations above 60 mg/liter decreased the algal concentration in the batch culture, and complete lysis of algal cells was observed within a few days at a detergent concentration of 100 mg/liter.
