Efficiency of Ammonia and Phosphorus Removal from a Colombian Agroindustrial Wastewater by the Microalgae Chlorella Vulgaris and Scenedesmus Dimorphus

The ammonia and phosphorus removal efficiencies of the microalgae Chlorella vulgaris and Scenedesmus dimorphus, during biotreatment of secondary effluent from an agroindustrial wastewater of a dairy industry and pig farming, were evaluated. The microalgae were isolated from a wastewater stabilization pond near Santafé de Bogota, Colombia. Batch cultures were made using both species in 4-l cylin...

Removal of ammonium and phosphorus ions from synthetic wastewater by the microalgae Chlorella vulgaris coimmobilized in alginate beads with the microalgae growth-promoting bacterium Azospirillum brasilense.

Coimmobilization of the freshwater microalga Chlorella vulgaris in alginate beads with the microalgae growth-promoting bacterium Azospirillum brasilense under semi-continuous synthetic wastewater culture conditions significantly increased the removal of ammonium and soluble phosphorus ions compared to immobilization of the microalgae alone. In continuous or batch cultures removal of these ions ...

Effects of Microalgae on the Removal of Nutrients from Wastewater: Various Concentrations of Chlorella vulgaris

The aim of this paper is to evaluate the efficiency of nutrients removal by Chlorella vulgaris (C. vulgaris). The study is comprised of five different fractions, having different quantities of C. vulgaris. From the batch reactor operations it was observed that increasing the content of C. vulgaris in the wastewater caused an apparent increase of removal rates in biochemical oxygen demand (BOD),...

Toxicity of nanoZnO in Daphnia magna fed with ZnO containing Chlorella vulgaris and Scenedesmus dimorphus algae

Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...
