Utilization of Microalgae for Urban Wastewater Treatment and Valorization of Treated Wastewater and Biomass for Biofertilizer Applications

Sustainability, Journal Year: 2023, Volume and Issue: 15(22), P. 16019 - 16019

Published: Nov. 16, 2023

Rapid urbanization has substantially increased freshwater consumption and consequent wastewater generation. The produced is an abundant resource of phosphorus, nitrogen, organics. Currently, well-established activated sludge processes are utilized in conventional treatment plants to remove However, removing nitrogenous phosphorus compounds continues be challenging energy-intensive for urban plants. Therefore, the current study aims understand how photosynthetic microalgae can recover nitrogen from wastewater-grown biomass may used as a biofertilizer biostimulant. Utilizing treated with promotes plant growth manner similar other organic manures fertilizers while minimizing nutrient loss soil. Furthermore, microalgal recovery nutrients could have potential energy reductions 47% 240% respectively. In addition producing suitable variety irrigation systems, sustainable alternative that reduce inorganic fertilizer usage.

This study exposed a microalgal consortium formed by Auxenochlorella protothecoides, Tetradesmus obliquus, and Chlamydomonas reinhardtii to six mixed wastewater media containing different proportions of primary (P) or secondary (S) effluents diluted in centrate (C). Algae could grow at concentrations up 50 %, showing no significant differences between effluents. After acclimation, microalgae cultivated 50%P-50%C 50%S-50%C grew rate similar that control cultures (0.59–0.66 d−1). These results suggest the acclimated both sewage streams modulating proportion species their metabolism. Acclimation also altered photosynthetic activity wastewater-grown samples compared control, probably due partial photoinhibition, changes composition, metabolic activity. No major were observed two with respect biochemical biomass yield, bioremediation capacity algae but grown effluent showed qualitatively higher exopolysaccharides (EPS) production than primary. Regarding remediation, WW proficient nutrient removal efficiencies (close 100 %); however, final pH value 11) would be controversial if system upscaled as it is over legal limit cause phosphorus precipitation, so CO2 addition required. The theoretical scale-up achieve water treatment costs 0.109 €·m−3, which was significantly lower typical activated sludge systems.

Efficiency of Microalgae Employment in Nutrient Removal (Nitrogen and Phosphorous) from Municipal Wastewater

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 260 - 260

Published: Jan. 17, 2025

Growing population, industrialisation, and demand for resources put pressure on the delicate balance of planet’s ecosystems. From alternative sources energy, healthier foods, cleaner water, an overall more sustainable economy, integration microalgae in various industries, that otherwise are based practices hurt environment, could be a successful solution. To reach goal, further research is required complex relationship between growth parameters (temperature, light intensity spectrum, nutrient distribution, inhibiting factors, so on). The scientific community successfully used to produce pigments, biofuel, animal fodder, methods sequestering heavy metals, toxic compounds from much more. In this review article, we approach use municipal wastewater treatment, mainly using nitrogen phosphorous present water as nutrients. Data were collected articles published last 7 years (2018–2024). results show very efficient at N P wastewater, well carbon, converting them high-value substances (proteins, lipids, carbohydrates, etc.) with applications multiple industries.
