Biodesalination of saline aquaculture wastewater with simultaneous nutrient removal and biomass production using the microalgae Arthrospira and Dunaliella in a circular economy approach

Desalination, Journal Year: 2024, Volume and Issue: 581, P. 117564 - 117564

Published: March 24, 2024

Freshwater scarcity is escalating due to factors such as climate change, droughts, increased demand, population growth, and poor water management practices. A promising sustainable solution this challenge biodesalination using microalgae. We demonstrate that Arthrospira platensis Dunaliella salina can thrive in saline aquaculture wastewater, reducing both its salinity the concentration of nutrients. The removal ability was quantified through measurements electrical conductivity (EC) ICP-OES, revealing reductions EC by up 45 % (from 31.5 17.2 ms/cm) for A. 35 20.5 D. salina. FESEM indicated formation a salt layer on surface microalgae, suggesting biosorption bioaccumulation likely mechanisms. FTIR spectroscopy analysis demonstrated binding functional groups within cell wall membrane with ions present medium. Scaling cultivation photobioreactor under non-sterile conditions validated processes' potential industrial-scale biodesalination. Although treated did not reach standards irrigation or potable use, approach provides preliminary desalination step, burden subsequent treatments simultaneously providing nutrient biomass production.

Unveiling the promise of biosorption for heavy metal removal from water sources

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 319, P. 100523 - 100523

Published: June 12, 2024

Heavy metals represent a significant contributor to water pollution, posing serious environmental and health risks due human activities industrialization. The release of heavy metal contaminants into sources has spurred extensive research wastewater treatment methods, including precipitation, evaporation, ion exchange, membrane processes, electroplating. However, these conventional techniques often prove costly, limited in effectiveness, may inadvertently exacerbate pollution concerns. This review underscores biosorption as highly promising alternative for effectively removing harmful ions from sources. Biosorption, physical technique, capitalizes on mechanisms such surface complexation, leveraging more economical biological materials biosorbents. Microorganisms, encompassing bacteria, fungi, algae, plant products, emerge pivotal agents biosorption, offering sustainable cost-effective approach. There is growing interest harnessing local microbiota aiming mitigate contamination without adverse impacts. Notably, both living deceased fungal biomass have garnered attention adsorbents eliminating solutions. behavior presents numerous advantages, warranting further fully exploit its potential endeavors.

Abstract Extensive anthropogenic activity has led to the accumulation of organic and inorganic contaminants in diverse ecosystems, which presents significant challenges for environment its inhabitants. Utilizing microalgae as a bioremediation tool can present potential solution these challenges. Microalgae have gained attention promising biotechnological detoxifying environmental pollutants. This is due their advantages, such rapid growth rate, cost-effectiveness, high oil-rich biomass production, ease implementation. Moreover, microalgae-based remediation more environmentally sustainable not generating additional waste sludge, capturing atmospheric CO 2 , being efficient nutrient recycling algal production biofuels high-value-added products generation. Hence, achieve sustainability's three main pillars (environmental, economic, social). Microalgal mediate contaminated wastewater effectively through accumulation, adsorption, metabolism. These mechanisms enable reduce concentration heavy metals levels that are considered non-toxic. However, several factors, microalgal strain, cultivation technique, type pollutants, limit understanding removal mechanism efficiency. Furthermore, adopting novel technological advancements (e.g., nanotechnology) may serve viable approach address challenge refractory pollutants process sustainability. Therefore, this review discusses ability different species mitigate persistent industrial effluents, dyes, pesticides, pharmaceuticals.
