Wastewater treatment by high density algal flocs for nutrient removal and biomass production.

Unlabelled: The present work investigated the efficiency of algal flocs biomass for the treatment of primary and secondary effluent in static and mixing conditions under different hydraulic retention time (HRT). Primary effluent fed cultures created a high-density biomass of 2.8 and 3.

Sustainable treatment of primary and secondary effluent by algal-bacterial flocculent biomass in raceway ponds.

Two 5.5-L raceway open ponds were used to evaluate the removal of organic material and nutrients from wastewater. Algal-bacterial flocs were placed in the ponds to treat primary and secondary effluent.
