Ferent influent N/P ratios (5, ten, 15, 20, 25, and 30) were discussed. two.3. Water Sample Collection and Determination Strategy 2.three.1. Collection and BMS-8 Biological Activity biomass Determination of Microalgae Owing for the smaller size of microalgae cells, poor sedimentation performance, and restricted density in aqueous solutions, the centrifugal process was used for the collection of microalgae. The microalgae liquid was placed in the centrifuge tube, and the centrifuge speed was set at 5000 rpm having a centrifuge time of 15 min. Far more microalgae inside the algal liquid could be collected, and the biomass of microalgae might be measured by the dry weight system. two.3.2. Water High-quality Analysis Approach Within this study, the concentrations of organic matter, total phosphorus, and ammonia nitrogen in the influent and effluent water of your reactor have been analyzed. The water sample was taken from influent and effluent water tank, respectively. The water sample was centrifuged at 5000 rpm for 15 min. Just after centrifugation, the supernatant was filtered by a 0.45 membrane, plus the filtrate was measured. The process of spectrophotometer was utilised to ascertain the nitrogen and phosphorus concentration of water samples. The total organic carbon was measured by a TOC meter (TOC-5000A, Shimadzu, Kyoto, Japan). Each of the above analyses were performed in triplicate, and their typical values have been listed. 3. Benefits three.1. Impact of Various Culture Modes on Microalgae Membrane Bioreactor Perforamence three.1.1. P. helgolandica tsingtaoensis Growth During the operation of microalgae membrane bioreactor, the functionality of microalgae membrane bioreactor is often better understood by way of the continuous monitoring ofMembranes 2021, 11,toautotrophic, heterotrophic, and mixotrophy culture reached 0.51 g/L, 0.60 g/L, and 0.77 g/L, respectively, along with the average biological growth prices have been 27.71 mg/(L ), 34.29 mg/(L ), and 46.43 mg/(L ), respectively. When there had been each organic and inorganic carbon sources in wastewater, the existence of organic carbon would change the mechanism of microbial photosynthesis and 6 of 16 respiration below light. It has been reported that the combination of photoautotrophic and heterotrophic culture can properly improve the biomass of microalgae [38,51,52]. The mixotrophic development may very well be the fastest solution to develop algal biomass compared together with the autotrophic and heterotrophic growth [53,54]. Therefore, in practical engineering applicaP. helgolandica tsingtaoensis biomass concentration. The changes in P. helgolandica tsingtaoensis biomass concentration below diverse culture modes are shown in Figure 2. It may be tions, it may very well be thought of to appropriately boost tiny molecular organics for example seen thatto promptly enhance the concentration was closely associated to the culture mode.

This was since the growth rate of P. helgolandica tsingtaoensis under autotrophic conditions was restricted by light intensity, especially when the concentration.
