Abstract
Improved wastewater management with beneficial utilization will result in enhanced sustainability and enormous cost savings in industries. Algae cultivation systems viz. raceway ponds, vertical tank reactors (VTR) and polybags were evaluated for mass production of algal consortium using carpet industry (CI) untreated wastewater. Overall areal biomass productivity of polybags (21.1 g mâ2 dâ1) was the best followed by VTR (8.1 g mâ2 dâ1) and raceways (5.9 g mâ2 dâ1). An estimated biomass productivity of 51 and 77 tons haâ1 yearâ1 can be achieved using 20 and 30 L capacity polybags, respectively with triple row arrangement. Biomass obtained from algal consortium was rich in proteins (â¼53.8%) and low in carbohydrates (â¼15.7%) and lipids (â¼5.3%). Consortium cultivated in polybags has the potential to produce 12,128 m3 of biomethane haâ1 yearâ1. To be economically viable, the capital expenditure for polybag reactors needs to be reduced to $10 mâ2 for bioenergy/biofuel production.
