“…The concentration of TDS, TS, and TSS of untreated DWW was 975.48, 1685.36, and 709.88 mg/ l respectively and they were reduced to 832, 1446.37, and 614.37 mg/l (Table 2). Moondra et al (2021b) reported that TDS, TS, and TSS were effectively removed by C. vulgaris. The maximum removal of 14.71% (TDS) was achieved while a minimum removal efficiency of TSS (13.45%) and 14.18% (TS) was recorded with C. vulgaris treatment.…”

Remediation of xenobiotics from wastewater is highly essential due to its harmful impacts. Several chemical and physical processes are used to recover xenobiotics from wastewater, including ion exchange, reverse osmosis, electrodialysis, and ultrafiltration. However, the biological method of employing microalgae, has aroused the scientific community’s interest due to its cheap operating costs and effectiveness in absorbing and/or removing organic and elemental contaminants from wastewater. Chlorella vulgaris was used as a biological absorbent, in the remediation of domestic wastewater (DWW). The results of this work indicated that C. vulgaris, effectively eliminated pollutants and improved the physicochemical characteristics of wastewater such as pH, DO, alkalinity. Simultaneously, it also decreased BOD, COD, suspended solids, heavy metals (HMs) such as iron (Fe), zinc (Zn), cadmium (Cd), mercury (Hg), copper (Cu), lead (Pb) and nutrient load (phosphate and nitrate) of DWW. Effective remediation of the pollutants was attained within 4h of C. vulgaris cultivation. The removal of toxic compounds such as 4-methoxy carbonyl benzo hydrazide, benzamine 4,4’ methylene bis, acetamide, and N-(2-methyl phenyl), was confirmed with GC-MS analysis. The removal of polysulfides and aliphatic bromo compounds was evident from the FTIR studies. Pearson’s correlation analysis showed a positive correlation between physicochemical variables and algal biomass. Hence, the current study recommends biological wastewater treatment,by utilizing C. vulgaris as an effective and eco-friendly option, for removing pollutants and restoring the physicochemical properties of water.

“…One effect on the physiology of the algae cells was the change in pH, which had an effect on one form of nutrient through an increase in alkalinity [66] after photosynthesis due to an increase in the pH of the effluent [67]. Increasing the pH causes self-flocculation, which eliminates algae suspended in the effluent and reduces the phosphorus concentration thanks to the interaction between cations and phosphates, which precipitate in a complex algae-mineral structure [68].…”

Phycoremediation of wastewater with microalgae is a viable option and is considered a process for cleaning up toxic waste using microalgae or macroalgae. Most water is modified by its use and must be treated before discharge. Given this situation, and following the example of other researchers around the world, our study focuses on the filtration method and combines it with the microalgae method to treat domestic wastewater. The aim of our work is to study the effects of using the microalgae system in combination with the decontamination and filtration system to reduce the nutrient content of domestic wastewater. The coupling of the two methods produced very significant results. However, the removal efficiencies for the filtered effluent increased to 86.34%, 100%, and 91.12% for COD, ammonia, and phosphate, respectively. The algae treatment offers an ecologically safe and less expensive system for nutrient removal and eliminates the need for tertiary treatment, which refers to the filtered treatment effluent, allowing us to conclude that the Chlorella vulgaris species has a very interesting influence on dissolved oxygen and that it had a very remarkable effect on COD, with a maximum reduction that reached 80%. The results obtained show that the phosphate content of the treated wastewater was significantly reduced during the cultivation period. In time, a decrease in solids was observed within the microalgae treatment system, influenced by the use of two different types of microalgae and the incorporation of the filtration system, which is based on the use of biosorption of methylene blue by biomass. The parameters analyzed in this study are hydrogen potential (pH), ammonia (NH3), phosphate ion (PO43−), chemical oxygen demand (COD), electrical conductivity (EC), total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), nitrates, and dissolved oxygen (DO).
