“…Algal biomass composition analysis C. vulgaris biomass from the culture at 5% CO 2 had 52.9% of protein, 6.4% of carbohydrate and 35% of lipid (Table 3). Compared to literatures [36,37], the algal biomass obtained from the present study had significantly higher lipid content and lower carbohydrate content, which was not expected considering the fact that the EC water has high nitrogen concentration. Chen et al reported that the algal biomass culturing on nitrogen rich wastewater (AD effluent) had lipid content of approximately 10% dry matter, and protein content of more than 20% dry matter [38].…”

a b s t r a c t An integrated system of electrocoagulation and algal cultivation was developed to treat a high strength wastewater-anaerobic digestion liquid effluent for reclaimed water and value-added algal biomass production. The integrated system synergistically takes advantages of both electrocoagulation and algal cultivation to enhance the efficiencies of wastewater treatment. The electrocoagulation treated wastewater had low turbidity with better light penetration (108 NTU) to enable algal growth. The algal cultivation had high removal efficiencies of phosphorus (99.4%) and nitrogen (88.2%). The dissolved iron in the electrocoagulation treated wastewater enhanced lipid accumulation of the algae. The results present that total phosphorus and nitrogen in the reclaimed water were 0.78 g L −1 and 35.5 mg L −1 respectively, and the harvested algal biomass had 35% of lipid, 53% of protein, and 6.4% of carbohydrate. This study concluded a new route for agricultural wastewater treatment that turns wastewater from an environmental liability into a valuable asset.

“…However, nitrogen or phosphorus still can limit the recycling of the whole N and P pools. Indeed, most N:P ratios of anaerobic digestate from livestock waste vary from 3 to 30 g N-NH 4 gP À1 in literature (Cañizares-Villanueva et al, 1994;Park et al, 2009;Levine et al, 2011;Chen et al, 2012). The heterogeneity of N:P ratios in digestate is due to AD inputs for nitrogen and phosphorus, the anaerobic digestion process and its management but also, concerning phosphate, functions of separation processes and chemical properties of digestate during anaerobic digestion.…”

“…In addition, microalgae are rich in lipids, starch and protein and this can be used as non food based feedstock for biofuels. (Chen et al, 2012). It also leads to no additional pollution and is safer ecologically and is also a very cheap method (Clarens et al, 2010, Wijffels et al, 2010.…”

Nutrient pollution of wastewater and its treatment is currently one of the biggest challenges being faced in waste management in India. As nutrient pollution leads to eutrophication and algal bloom, the present research aims to reduce the nutrient load in wastewater using microalgae, before its release in water bodies. Microalgae was successfully isolated from municipal wastewater fed urban lake in Bengaluru and inoculated in domestic wastewater to carry out the treatment. Growth curve analysis and biomass studies were carried out on the microalgae isolated from lakes. The dry algal biomass was found to be 1.078gm/L and biomass productivity was 24.5mg/L/d. The nutrient removal efficiencies were found to be 33.33%, 66.66%, 80%, 88.88% and 88.235% for Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Nitrate Nitrogen and Total Phosphates respectively. Crude lipid extracted was 22.54% of the weight of dry algae.
