title: Effect of hydrophilic coating for membrane assisted air diffuser for Chlorella vulgaris cultivation
ispublished: pub
note: cited By 3
abstract: Microalgae cultivation has high potential in capturing atmospheric carbon dioxide (CO2) but are limited by poor CO2 mass transfer to the algae. Therefore, improving mass transfer by increasing total contact area of gas-liquid through minimizing bubble size formed is investigated. In this project, the effect of polyether block amide (PEBAX® 1657) coating (i.e. different concentration and coating cycle) on polyvinylidenefluoride (PVDF) membrane surface properties are investigated and their impact on algae cultivation are evaluated using Chlorella vulgaris for duration of 14 days. The presence of functional groups from PEBAX coating showed the success of coating process and membrane hydrophilicity is improved from 111.19 ± 0.10° to 40.57 ± 1.29° when PEBAX 2.0 wt is used. Membrane porosity is reduced when PEBAX concentration and number of coating cycle increased. Concentration of biomass is the highest (1.107 g/L) when PVDF/PEBAX 2.0 wt is used, likely because of small size of CO2 bubbles delivered into culture medium. © 2020 University Mohammed Premier Oujda.
