“…Many previous studies have reported the treatment of industrial, municipal and agricultural wastewater by micro algal culture systems (Franchino et al, 2013;Ji et al, 2013;Lau et al, 1995;Lau et al, 1998;McGinn et al, 2012;Singh et al, 2012;Srinivasan & Subramaniam, 2009;Talbot & delaNoue, 1993;Tam & Wong, 1989;Williams, 2003). Such type of schemes has significant applications in the reduction of nutrient release in associated streams by assimilatory uptake of nitrogen that in turn decreases the rate of eutrophication of receiving streams and also provides oxygen for nitrification and biological organic matter oxidation (Kothari et al, 2013;Mata et al, 2010;Park et al, 2010;Wolanski et al, 2009). A novel thought, mixotrophic wastewater treatment has been considered at the laboratory scale and can be easily upgraded to large scale industries by recycling of nutrients and recovery of energy in a cost efficient manner (Subhash et al, 2014;Venkata Mohan et al, 2014).…”

The present study investigates the possibility of integrating an existing industrial large scale biomass production with the treatment of waste water in which a mixture of organic and inorganic rich pollutants was used as a medium. This study suggests that the replacement of a defined medium with a complete mixotrophic medium gives a significant statistical difference in terms of growth parameters i.e. biomass production and specific growth rate.The green microalga C. pyrenoidosa was cultivated under different mixotrophic conditions for evaluation of biomass production. Inorganic defined fog's medium supplemented, with raw dairy wastewater led to 1.37g/L biomass production in comparison to 1.2g/L obtained with pure glucose revealing 14.16% increase. The study also involves the supplementation of raw dairy wastewater as an organic carbon source in an inorganic medium comprising municipal treated water and reverse osmosis (RO) treated wastewater and attained 2.4g/L and 1.6g/L of biomass respectively, as compared to 0.3g/L and 0.16g/L obtained in the wastewaters alone revealing 700% and 900% increase respectively. Mixotrophic regimen cells as analyzed by a 2D Fourier transform infrared (FTIR) spectroscopy for its biochemical content revealed that fog's blended raw dairy waste (RDW) regimen cells had maximum

“…This fact can be explained by the consumption of the microalga and not by the volatilization of the ammonium in the form of ammonia, since the pH is maintained at 7.6 ± 0.1. According to Park et al (2010), the elevation of pH favors the loss of nitrogen due to the displacement of the balance between ammonium and ammonia. Abeliovich & Azov (1976) tested various ammonium and pH levels on Scenedesmus obliquus cultures and found that photosynthesis and growth inhibition at concentrations and pH values above 36 mg L -1 and 8.0, respectively.…”

OUTDOOR CULTIVATION OF Scenedesmus obliquus BR003 IN STIRRED TANKS BY AIRLIFT

ABSTRACT:The use of microalgae as a source of raw material for biofuel production has been highly targeted. Compared to other biological options for the capture and use of CO2, microalgae crops have the following advantages: high productivity, lack of competition with feed and foodbased products, use of unproductive and non-arable land, and allowance of the use of wastewater for its cultivation. The use of wastewater from industrial, agricultural, and domestic sewage has been indicated as an alternative means to reduce the cost of crops, since such waste is generally released into the environment without previous treatment. This work addresses the use of petrochemical wastewater (ARP) from effluent produced at the Gabriel Passos Refinery (Petrobrás refinery unit) for the cultivation of a strain of Scenedesmus obliquus BR003. Twelve experimental units of 20 L each were constructed in the experimental area of the Biofuel Laboratory of the Federal University of Viçosa, Minas Gerais, Brazil in an uncontrolled environment, and the cultures were evaluated by quantification of total carbohydrates, total lipids, dry biomass, and growth evaluated by absorbance. The results showed that the wastewater from petrochemical effluent is an efficient growth medium for the growth of Scenedesmus obliquus BR003 microalgae for large-scale cultivation on land that is not suitable for other agricultural crops.

“…The anode was inoculated with the anaerobic sludge from the Peppers Ferry Regional Wastewater Treatment Plant (Radford, VA, USA). To mimic the digestion effluent of livestock waste (Park et al 2010), the anode influent solution was prepared containing (per liter of deionized water): sodium acetate, 1.5 g; NH4Cl, 3.0 g; NaHCO3, 2.0 g; NaCl, 0.15 g; MgSO4, 0.005 g; CaCl2, 0.006 g; and trace elements solution (Angenent and Sung 2001), 1 mL. The cathode chamber was initially filled with 180 mL of deionized water.…”

(academic)Recovering valuable resources from wastewater will transform wastewater management from a treatment focused to sustainability focused strategy, and creates the need for new technology development. An innovative treatment concept -osmotic bioelectrochemical system (OsBES), which is based on cooperation between bioelectrochemical systems (BES) and forward osmosis (FO), has been introduced and studied in the past few years. An OsBES can accomplish simultaneous treatment of wastewater and recovery of resources such as nutrient, energy, and water (NEW). The cooperation can be accomplished in either an integrated (osmotic microbial fuel cells, OsMFC) or coupled (microbial electrolysis cell-forward osmosis system, MEC-FO) configuration.In OsMFC, higher current generation than regular microbial fuel cell (MFC) was observed, resulting from the lower resistance of FO membrane. The electricity generation in OsMFC could greatly inhibit the reverse salt flux. Besides, ammonium removal was successfully demonstrated in OsMFC, making OsMFCs a promising technology for "NEW recovery" (NEW: nutrient, energy and water). For the coupled OsBES, an MEC-FO system was developed. The MEC produced an ammonium bicarbonate draw solute via recovering ammonia from synthetic organic solution, which was then applied in the FO for extracting water from the MEC anode effluent. The system has been advanced with treating landfill leachate. A mathematical model developed for ammonia removal/recovery in BES quantitatively confirmed that the NH4 + ions serve as effective proton shuttles across cation exchange membrane (CEM). Resource Recovery by Osmotic Bioelectrochemical Systems towards Sustainable Wastewater TreatmentMohan Qin Abstract (general audience)Nowadays, wastewater is no longer considered as waste. Instead, it is a pool for different kinds of resources, such as nutrient, energy, and water (NEW). Various technologies were developed to achieve NEW recovery from wastewater. A novel concept, osmotic bioelectrochemical system (OsBES) has been introduced and studied in the past few years. OsBES is based on two technologies: bioelectrochemical systems (BES) and forward osmosis (FO); and the corporation between these two technologies could accomplish simultaneous wastewater treatment and resource recovery. We investigated two kinds of OsBES: one is osmotic microbial fuel cells (OsMFC), and the other is microbial electrolysis cell-forward osmosis system (MEC-FO). For OsMFC, a mathematical model was built to understand the internal resistance, which will affect the current generation according to Om's law (I=U/R). The salt transport across the cation exchange membrane (CEM) is related to the current generation. The ion transport, especially ammonium/ammonia transport, across CEM membrane in BES was modelled, which will help the BES design and operation for ammonia recovery systems. The system performance for wastewater treatment and resource recovery in MEC-FO was fully investigated with both synthetic wastewater and landfill leach...
