“…At day 3, 0.45 g/L, 0.6 g/L, 0.5 g/L, 0.4 g/L, and 0.33 g/L dry biomass were produced for the wastewater samples L0:P100, L25:P75, L50:P50, L75:P25, and L100:P0. Compared to day 3, day 9 reported massive growth in the microalgae 21%, 15.3%, 18.1%, 22%, and 30.7% [8,9]. From the findings, it is clear that industry leather wastewater produced higher dry biomass compared to the piggery wastewater.…”

“…At the final moment of day 15, the respective lipid content of the samples is 1.5%, 1.75%, 1.3%, 1.01%, and 0.98%, respectively. Lipid content was dramatically improved when they are cultivated in the leather wastewater than piggery [9,22]. The main reason for the better lipid productivity for the leather WW was absorbed nutrients.…”

“…Microalgae can also be cultivated in both indoor and outdoor areas. For instance, microalgae grow in both photo autotrophically and heterotrophically in wastewater [9][10][11]. The presence of heavy metals in the water poses a great threat to the human health due to its toxicity.…”

Removal of high toxic metals from the wastewater was one of the mandate options to avoid the environmental pollution caused by the wastewater plant. Microalgae cultivation on the wastewater was one of the hopeful methods to convert the waste into useful by-product. In this study, the Chlorella sp. was used to remove the presence of the total nitrogen (TN) and total phosphorous (TP) in the wastewater. Added to the above, the biomass and lipids of the Chlorella sp. were examined with respect to the incubation time. Chlorella sp. was cultivated using BG11 medium. Here, two different types of wastewater had been used, one from leather industry and other priggery waste. The respective ratio of leather and piggery wastewater used in the current study was 0 : 100, 25 : 75, 50 : 50, 75 : 25, and 100 : 0. The total percentage of the nitrogen and phosphorous removal by the microalgae within 14 days was determined. Based on the findings, it is clear that Chlorella sp. L33 was highly efficient to absorb the nitrate and phosphorous content in the wastewater. With regard to the biomass production, the priggery wastewater treated reported the maximum biomass for 100 μmol/L with 0.55 g/L. However, the 100 μmol/L has higher pH content than other test samples. By varying the ratio of the wastewater, the removals rates can be improved.

“…Biomass accumulation, through the removal of nutrients present in W through the use of microalgae, was the objective of researchers such as Fan et al (2023), Paulenco et al (2023), Liu et al (2023), Zhuang et al (2023), Zuo et al (2023), , Qv et al (2023) and Muthuraman et al (2023). The microalgae species used were Chlorella sp., Nannochloris sp., Hybrid, Chlorella FACHB-30, Chlorella FACHB-5, Chlorella vulgaris, Chlorella sorokiniana and Coelastrella sp.…”

E Objective. To indicate the condition of the wastewater treatment with microalgae (WTwM) research. Methodology. The words treatment, wastewater, and microalgae, were entered as keywords in a search under "article title" in SCOPUS. The documents found were saved and exported as a file with a .bb extension. From R Studio, the BIBLIOMETRIX interface was linked to R Statistics. The interface was opened from MOZILLA to import the .bb file. Results. There is a significant increase in the number of papers published since 2013, up to 68 articles in 2022. The authors with the highest number of contributions on the subject are Ivet Ferrer and Joan García. The countries most involved in this issue are China, Spain, India and Brazil; China is the one with the highest number of publications. The WTwM studies in 2023 are concerned with investigating biomass accumulation and nutrient removal as a way to make sustainable use of the process. Conclusions. WTwM is a research topic that is studying and disseminating knowledge since the 80's. The author who stands out the most is Ivet Ferrer. China has little collaboration with scientists from other countries. The most recent WTwM studies address issues related to biodiesel production and biogas production. The topics to be addressed in future research will be related to the study of temperature, osmotic capacity, pH and O2 levels.
