Microalgae-based livestock wastewater treatment (MbWT) as a circular bioeconomy approach: Enhancement of biomass productivity, pollutant removal and high-value compound production

Journal of Environmental Management, Journal Year: 2022, Volume and Issue: 308, P. 114612 - 114612

The intensive livestock activities that are carried out worldwide to feed the growing human population have led significant environmental problems, such as soil degradation, surface and groundwater pollution. Livestock wastewater (LW) contains high loads of organic matter, nitrogen (N) phosphorus (P). These compounds can promote cultural eutrophication water bodies pose hazards. Therefore, humanity faces an enormous challenge adequately treat LW avoid overexploitation natural resources. This be accomplished through circular bioeconomy approaches, which aim achieve sustainable production using biological resources, LW, feedstock. Circular uses innovative processes produce biomaterials bioenergy, while lowering consumption virgin Microalgae-based treatment (MbWT) has recently received special attention due its low energy demand, robust capacity microalgae grow under different conditions possibility recover transform nutrients into highly valuable bioactive compounds. Some high-value products may obtained MbWT biomass pigments for food animal feed, nutraceuticals, biofuels, polyunsaturated fatty acids, carotenoids, phycobiliproteins fertilizers. article reviews recent advances in (including swine, cattle poultry wastewater). Additionally, most factors affecting nutrient removal productivity addressed, including: (1) microbiological aspects, strain used interactions between microbial populations; (2) physical parameters, temperature, light intensity photoperiods; (3) chemical C/N ratio, pH presence inhibitory Finally, strategies enhance productivity, acclimation, UV mutagenesis multiple culture stages monocultures multicultures) discussed.

Application of Natural Coagulants for Pharmaceutical Removal from Water and Wastewater: A Review

Water, Journal Year: 2022, Volume and Issue: 14(2), P. 140 - 140

Published: Jan. 6, 2022

Pharmaceutical contamination threatens both humans and the environment, several technologies have been adapted for removal of pharmaceuticals. The coagulation-flocculation process demonstrates a feasible solution pharmaceutical removal. However, chemical coagulation has its drawbacks, such as excessive toxic sludge production high cost. To overcome these shortcomings, feasibility natural-based coagulants, due to their biodegradability, safety, availability, investigated by researchers. This review presented recent advances using natural coagulants compound from aqueous solutions. main mechanisms water wastewater are charge neutralization polymer bridges. Natural extracted plants more commonly than those animals affordability. competitive in terms performance environmental sustainability. Developing reliable extraction method is required, therefore further investigation essential obtain complete insight regarding effect factors during coagulants. Finally, indirect application an step implementing green treatment technologies.

Application of Natural Coagulants in Water Treatment: A Sustainable Alternative to Chemicals

Water, Journal Year: 2022, Volume and Issue: 14(22), P. 3751 - 3751

Published: Nov. 18, 2022

Water treatment (WT) is currently among the major areas of research due to depletion water resources and fearmongering regarding environmental pollution, which has compelled upgrading conventional WT technology towards recycling reuse. This review aims provide current state natural coagulants their application in purification surface as sufficient clean required for household needs, health security, safety. A thorough systematic existing literature was performed, information related using compiled from 237 articles under various sections a computerized bibliographic search via PubMed, Scopus, Web Science, Google Scholar, CAB Abstracts, several websites. The work provides explicit merits limitations, outlines methods increase coagulation performance, highlights mechanism, efficacy, valorization potential, sustainability. From obtained, it can be concluded that although chemical are efficient WT, they usually expensive, toxic, associated with issues, thus non-sustainable. sustainable alternative use coagulants, readily available, economical, easy use, biodegradable, non-toxic, eco-friendly, effective, generate lower sludge volumes. They an adsorption process involves polymeric bridging or neutralization charge. efficiency ranges 50–500 nephelometric turbidity units (NTUs), similar chemicals. Thus, deployed regimes contribute security rural populations developing countries. It unfortunate that, despite known benefits acceptance, commercialization, widespread industrial across globe still low. Therefore, there need more exhaustive investigations mode action, adoption, commercialization chemicals circular economy.
