Microalgae has emerged as a promising approach for removing substrate and nutrient from wastewater with the concomitant biofuel production. The substrate and nutrient removal are influenced by several factors such as C/N ratio, F/M ratio, pH, and DO. This study aims to determine the efficiency of substrate and nutrient removal with the growth rates of microalgae and biomass by varying the addition of aeration and substrate. Intermittently aerated reactors were used with the flow rate of 14 L/minute. The batch reactors were prepared by adding glucose substrate of 50 mg/L (Ra0A), 100 mg/L (Ra0B), and 150 mg/L (Ra0C) without aeration; 50 mg/L (Ra12A), 100 mg/L (Ra12B), and 150 mg/L (Ra12C) with 12-hour aeration, and 50 mg/L (Ra24A), 100 mg/L (Ra24B), and 150 mg/L (Ra24C) with 24-hour aeration. The substrate removal, expressed as chemical oxygen demand (COD) in the reactor with aeration, showed the efficiency of 73.88% ± 2.05 (12-hour aeration), 75.2% ± 3.97 (24hours aeration), and 69.86% ± 5.69(without aeration). Nutrient removal as ammonia-N (NH3-N) gave high removal value of 98.3% ± 0.11 and the removal of nutrient as phosphate (PO3-4) showed the efficiency of 54.3% ± 0.1. The growth rate of microalgae and biomass exhibited the highest value in Ra24C reactor with the values ??of 0.0229/day and 0.1295/day, respectively. The pH values ??indicated a shift from normal to alkaline while DO values ??increased by the addition of 12 and 24-hour aeration.

“…A very similar trend in the growth curves was exhibited by the immobilized and free cells because the physiological activities of the microalgae cells within the matrix were not affected, despite their being in the immobilized state. The cell density of the immobilized C. vulgaris increased from 2.22 10 7 to 2.17 10 8 cells mL -1 during the period of the exponential phase (cultivation days [3][4][5][6][7][8][9][10][11][12][13][14], in which the microalgae bead becomes greener from day 3 to day 14. Some previous studies had recorded a higher rate of chlorophyll synthesis of the alginate-and carrageenan-immobilized C. vulgaris cells as compared to the free cells.…”

An immobilization method for simplified separation of cultured cells and their products from the growth media was developed. The growth rates of both immobilized and free cells of the microalga Chlorella vulgaris were compared. The free and immobilized cells reached nearly identical cell densities. The reported immobilization strategy uses a combination of matrices (sodium alginate (S A ), calcium alginate (C A ), and sodium carboxymethyl cellulose (C MC )) at different matrix/ microalgae volumetric ratios of 0.3:1 and 1:1. The microalgae in the S A C A C MC /Mc (0.3:1) beads achieved the highest cell density. The cells immobilized in S A C A C MC /Mc (0.3:1) gave the highest lipid yield, as compared to the cells immobilized in S A . Pore size and membrane thickness analysis as well as surface images of S A C A C MC /Mc (0.3:1) showed that the mixed matrix had a unique structure favoring lipid production.
