effect of sparger orifice diameter on fouling in a novel aerated-membrane photo bioreactor (ampbr) containing microalgae

Membrane photo bioreactors can be regarded as well-established and fruitful approach they are widely used in industry with different good features in this article, a novel aerated-membrane photo bioreactor (ampbr) was built in order to consider the role of orifice diameter (do) on fouling since the most striking drawback is fouling and it could make membrane efficacy less in addition, some factors could pander to this problem, such as protein in microalgea and the design of bioreactorsthere exist some ways to reduce fouling including aeration, backwash and mechanical cleaning this study is approved that using air sparger with various dos for releasing air bubbles would be significant to diminish the rate of membrane fouling so two dos 05 mm and 15 mm were separately used to consider the impact of them on membrane fouling furthermore, different resistances were calculated alongside the amount of protein it is concluded that when the do of air sparger is 05mm, the cake layer is max on the other side, when the do of air sparger is 15mm, the cake layer is lower
