The salinity have been diluted3.45 . The main pollutants in wastewater were as follows: TOC 4020 mg/L, ammonia The mg/L, and phosphate 3 mg/L. The pH was adjusted and mg/L, ammowas 3.45 .50 primary pollutants in wastewater were as follows: TOC 4020 maintained within the set mg/L, and phosphate three and 1 mol/L was adjusted and maintained inside the of nia 50range with 1 mol/L HClmg/L.

The Experimental Method two.2.3. The Experimental Process This study aimed to explore the therapy efficiency of mariculture wastewater within the This study aimed to discover the therapy efficiency of mariculture wastewater in the microalgae membrane bioreactor beneath distinctive operating conditions. The experimental microalgae membrane bioreactor beneath various operating circumstances. The experimental arrangement is listed in Table 1. The cultures have been bubbled with air to provide CO2 . The arrangement is listed in Table 1. The cultures have been bubbled with air to supply CO2. The continuous influent mode was adopted to study the effects of diverse influent TOC concontinuous influent mode was adopted to study the effects of distinct influent TOC concentrations, Cholesteryl sulfate Epigenetic Reader Domain different influent pHs, and different culture modes on microalgae membrane centrations, unique influent pHs, and distinctive culture modes on microalgae membrane bioreactor. The batch culture was initial employed to increase the initial microalgae concentration, bioreactor. The batch culture was 1st applied to enhance the initial microalgae concentration,Membranes 2021, 11,five ofand then the membrane filtration was use to study the influence of N/P around the microalgae membrane bioreactor.Table 1.

In every single reactor, the initial biomass was 0.12 g/L. At present, the reactor was nonetheless in operation, plus the experiment outcome for 20 days’ operation was supplied. The nutrient removal efficiency and biomass production of microalgae membrane bioreactor beneath different culture modes (photoautotrophic, heterotrophic, and mixotrophy), unique influent TOC concentrations (40 mg/L, 80 mg/L, and 120 mg/L), unique influent pH values (6, 7, eight, and 9), and dif.
