Abstract

Aquatic treatment indicated that the efficiency ofL. gibba in algal removal was higher in mixtures of Nile and wastewater systems and the percent algal reduction ranged from 86 to 90%. The maximum percentage of algal removal was achieved with a water system with an equal mixture of Nile and wastewater, this was followed by the water system with Nile to wastewater in a ratio of 1∶3 (89%). The data further revealed that the most highly predominant species were contributed byBacillariophyta. L. gibba treatment of the wastewater induced a reduction in the total species number of phytoplankton populations to only 5 species of diatoms with the order of dominance as follows:Synedra ulna, Navicula cryptocephala, Nitzschia acicularis, Melosira granulatus andCyclotella glomerata.
