We hypothesize that the net effect of organic matter (from all sources) in domestic wastewater treatment ponds may tend to promote fecal bacteria survival at higher algal cell concentrations. The aim of this study is to understand better, the role of algae in the removal of fecal bacteria from algal based ponds and to specifically investigate the effect of varying algal concentrations on fecal bacteria removal in algal based ponds. Batch laboratory experiments were conducted using light of wavelengths, 380-780 nm. Algae were grown by natural colonization and used for inoculating the setup.
