“…Furthermore, it is observed that the total NH 4 -N percent removal is found to be 99.80 % from the initial level of 25.38 ml NH 4 -N in the MMBR. The reported NH 4 -N removal efficiency varies depending on the medium composition and environmental conditions, such as the initial nutrient concentration, light intensity, light/dark cycle, and algae species [23][24][25]. In the aerobic MMBR, under excess oxygen, NH 4 -N is converted by nitrifying bacteria to nitrites and nitrates.…”

In present research, a microalgae membrane bioreactor (MMBR) was constructed by combining the optical panel photobioreactor (OPPBR) and membrane bioreactor (MBR). Experiments were conducted in MMBR pilot-plant configuration for 150 days. A biomass productivity of 2.53 g/l/day with light transmittance of 94 % at a 300-mm depth in the OPPBR was achieved. The total reduction of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in the MMBR were found to be 96.99 and 97.09 %, respectively. Additionally, the removal of total nitrogen (TN), NH4-N, NO3-N, total phosphorus (TP), and PO4-P were 96.38, 99.80, 97.62, 92.75, and 90.84 % in MMBR, respectively. These results indicated that the MMBR process was highly effective for COD, BOD, and nutrient removal when compared to the OPPBR or MBR process.

“…The nutrient uptake by microalgae is a very complex process as it can depend on many parameters that may include nutrient concentration, light intensity, the nitrogen/phosphorus ratio, light/dark cycle (Aslan and Kapdan 2006;Kim et al 2012;Singh and Thomas 2012;Wang et al 2009;Hammouda et al 1995;Gonzalez et al 1997;Gantar et al 1991;Yun et al 1997;Hongyang et al 2011;Kim et al 2010). The N:P ratio in the wastewater is an equally important parameter that will affect the efficiency of microalgae wastewater treatment.…”

“…Microalgae have also been researched in its sorption ability for heavy metal containing wastewater (Chinnasamy et al 2010;Cai et al 2013). This has opened up the opportunity to utilize the available unlimited resources of wastewater in order to cultivate microalgae for the dual purpose of removing nutrients and producing biofuels (Kim et al 2010).…”

“…In this study, N and P removal efficiencies reached 60% within short HRT compared to [16], which took 4 days to achieve removal efficiency of approximately 62% N and 55% P from septage wastewater by C.vulgaris. Also, C. vulgaris removed half of nitrogen from wastewater effluent in a batch mode in 2 days [17]. …”

Abstract-To determine the performance of microalgae photobireactor for advanced wastewater treatment and microalgal biomass production, Chlorella vulgaris was cultured with final effluent from sewage treatment plant in batch condition. The average specific growth rate was 0.103 d -1 because low P concentration inhibited algal growth. 60% of N and P concentrations were removed from the system in 2 days. When the system operated under a semi-continuous condition with hydraulic retention time (HRT) 2 days, the microalgae showed growth rate of 0.452 d -1 and 0.277 d -1 in primary effluent and final effluent, respectively. 30% of N and 53% of P were removed from primary effluent and 44% of N and 84.2% of P were removed from final effluent. These results suggest that semi-continuous mode offers higher biomass production and appropriate HRT were needed for high N and P removals.Index Terms-Nitrogen and phosphorus removal, microalgae, photobioreactor, wastewater.
