TL;DR: Natural coagulants have the potential as an alternative technique for harvesting microalgae from greywater through optimized harvesting of M. oleifera and Strychnos potatorum seed flours by response surface methodology.
Abstract: Harvesting of Botryococcus sp from greywater by Moringa oleifera and Strychnos potatorum seed flours was optimized by response surface methodology Three factors including dosage (10–60 mg L−1), settling time (30–120 min), and pH (6–9) were investigated Optimal operating parameters were obtained with dosage of 35 mg L−1, pH of 75, and settling time of 75 min, which demonstrated predicted and experimental recovery of 8680 and 8560% for M oleifera, and 4133 and 3830% for S potatorum, with R2 coefficient of 0947 and 0953, respectively The interaction between the factors was significant (p < 005) at the optimal operating parameters Scanning electron microscope (SEM) observed that the surface appearance of M oleifera seed flour was smoother compared to S potatorum, which reflects the higher potential of M oleifera seed flour to adhere to microalgae cells Natural coagulants have the potential as an alternative technique for harvesting microalgae from greywater
