Is study.Water 2021, 13,g dw/L ) and carbon fixation price (0.101 g c/L ) having a range up to ten CO2. The optimum CO2 concentration was calculated as five.35 . Razzak et al. [37] also reported that the 4 CO2 can recover the maximum biomass production in the cultivation of Chlorella sp. amongst 2 2 CO2. This indicated that adding CO2 of low concentration can tremendously pro11 of 13 mote the growth of microalgae. The distinctive optimum CO2 concentrations may be due to the different microalgae species in the literature compared with this study.Figure 7.

ConclusionsFrom From this study, the following conclusions might be created: produced: (1) When urea was employed a a nitrogen supply, the growth of S. dimorphus was in(1) When urea was employed asasnitrogen supply, the growth of S. dimorphus was elevated. The high concentration of inorganic nitrogen (ammonia nitrogen and nitrate nitrogen) creased. The higher concentration of inorganic nitrogen (ammonia nitrogen and nitrate nicould inhibit inhibit the of S. dimorphus. trogen) could the growth development of S. dimorphus. (two) (2) The growth of S. dimorphus reached its highest when phosphate was four mg/L and highest when phosphate was 4 mg/L the pH was 7. pH was the (three) The bacteria in actual sewage can promote the development microalgae (three) The bacteria in actual sewage can promote the development of microalgae and facilitate biomass harvest. biomass harvest. (4) Under the condition of an illumination intensity of 15,000 Lux, when the optimal (4) Below the condition of an illumination intensity of 15,000 Lux, when the optimal everyday illumination time was about 1515 h, the development S. dimorphus in actual sewage was everyday illumination time was about h, the development of of S. dimorphus in actual sewage was optimum. optimum. (5) When adding 2 (0.004 v/v in) CO , the growth of S. dimorphus was the most effective in (five) When adding 2 (0.004 v/v in)CO22 ,the development of S. dimorphus was the top in each synthetic and actual wastewater. both synthetic and actual wastewater.Author Contributions: Conceptualization, L.L. and K.C.; methodology, K.C.; software program, K.C.; validation, L.L. and K.C.; formal evaluation, K.C.; investigation, L.L.; sources, K.C.; information curation, K.C.; writing–original draft preparation, K.C.; writing–review and editing, L.L.; visualization, K.C.; supervision, L.L.; project administration, L.L.; funding acquisition, L.L.
