Опубликована: Янв. 1, 2025

Wastewater management has become crucial as the global population grows. Construction wetlands (CWs) have emerged a promising way to treat wastewater, providing natural and cost-effective alternative. This review aims present state-of-the-art of CWs for sustainable wastewater management. The major parameters affecting constructed are characterized unit parameters, operational meteorological parameters. media vegetation, hydraulic loading rate flow rate. Among this, can be controlled by operators or design engineers whereas in case uncontrollable ones. study examines initially interaction between performance CWs. Then effect are, namely, temperature, wind speed, relative humidity on Furthermore, overall challenges faced critically reviewed, suitable recommendations suggested improve discussed. concludes that maximize CW efficiency, considerations include selecting appropriate (surface flow, subsurface hybrid), determining configuration system (horizontal vertical flow), substrate material, incorporating innovative technologies such solar-powered aeration systems biochar-amended substrates. In future, integrating with other advanced treatment technologies, enhancing plant species microbial consortia, adapting climate variations, developing better monitoring modeling methods.

Abstract Wetland restoration is a popular nutrient management strategy for improving water quality in agricultural catchments. However, wetland’s ability to retain phosphorus highly variable and wetlands can sometimes be source of downstream ecosystems. Here, we used meta-analysis approach explore the sink capacity 139 both total (TP) more bioavailable form, phosphate (PO 4 3− ), at seasonal annual timescales. Median retention efficiency across all studies 32% TP 28% PO , however range extremely broad. We found that are often sinks (84% site-years) (75% site years). The median within (2.0 g·m −2 ·yr −1 ) greater than release by sources (−0.5 ). In contrast, (0.8 similar magnitude released (−0.7 from coincides with higher hydraulic loading rates, lower influent concentration, legacy soil/sediment phosphorus. Phosphate releases were especially common treating municipal wastewater, as well restored constructed flashy, precipitation-driven flow. experimental design may inherently bias our understanding wetland performance conducted mesocosms outperform other types. Analysis monthly data demonstrated significant temporal variability dynamics, switching many times year, but no generalizable trends. Our results highlight value restoring point ways furthering their utility towards simultaneously targeting enhancing measures avoidance.

From Scarcity to Abundance: Nature-Based Strategies for Small Communities Experiencing Water Scarcity in West Texas/USA

Sustainability, Год журнала: 2024, Номер 16(5), С. 1959 - 1959

Опубликована: Фев. 27, 2024

Water scarcity is one of the global challenges that threatens economic development and imposes constraints on societal growth. In semi-arid expanse West Texas, small communities are struggling with both growing populations decreasing water resources in regional aquifer. This study compares two nature-based methods could solve this problem. The first approach uses ponds wetlands to make natural processes work together treat wastewater community receives. We applied a novel Pond-in-Pond system, which offers advantages compared conventional pond system configurations. unlocks strategic hydrodynamic by introducing deeper anaerobic pit surrounded berms, then outflows into larger pond. second consists an alternative strategy integrates waste stabilization ponds, storage basin, reuse for crop irrigation—a feat not only treats but also enriches soil fertility. Both approaches were analyzed terms potential pollution control. land application had better return investment emphasized importance innovative solutions sustainable management arid regions, offering benefits. conveys clear message: where scarce, innovation can grow; problems big, available; nature’s understood, they be used.

Enhanced degradation of ibuprofen in an integrated constructed wetland-microbial fuel cell: treatment efficiency, electrochemical characterization, and microbial community dynamics

RSC Advances, Год журнала: 2023, Номер 13(43), С. 29809 - 29818

Over the past few decades, there has been a growing concern regarding fate and transport of pharmaceuticals, particularly antibiotics, as emerging contaminants in environment. It proposed that presence antibiotics at concentrations typically found wastewater can impact dynamics bacterial populations facilitate spread antibiotic resistance. The efficiency currently-used treatment technologies eliminating pharmaceuticals is often insufficient, resulting release low these compounds into In this study, we addressed challenges by evaluating how different influent ibuprofen (IBU) influenced laboratory-scale, integrated constructed wetland-microbial fuel cell (CW-MFC) system seeded with Eichhornia crassipes, terms organic matter removal, electricity generation, change community structure compared to unplanted, sediment MFC (S-MFC) abiotic S-MFC (AS-MFC). We observed addition IBU (5 mg L-1) resulted notable decrease chemical oxygen demand (COD) suggesting high caused partial inhibition for electroactive microbial due its complexity aromaticity. However, CW-MFC could recover from after an acclimation period unplanted S-MFC, even though level was increased up 20 L-1, plants CW-MFCs have beneficial role relieving anode respiration levels IBU; thus, promoting metabolic activity community. Similarly, removal (i.e., 49-62%) much higher SMFC 29-42%), AS-MFC 20-22%) during all experimental phases. addition, our throughput sequencing revealed performance associated increasing relative abundances several groups are closely affiliated fermentation. summary, results show demonstrates suitability effective generation.

The impact of climate change on water availability and quality has affected agricultural irrigation. use treated wastewater can alleviate in agriculture. Nevertheless, it is imperative to ensure proper treatment before reuse, compliance with current regulations this practice. In decentralized scenarios, the lack adequate facilities poses a challenge providing for Hence, there critical need develop implement innovative, feasible, sustainable solutions secure alternative source. This study proposes integration intensive natural systems, specifically, combination up-flow anaerobic sludge blanket reactor (UASB), membrane bioreactor (AnMBR), constructed wetlands (CWs), ultraviolet (UV) disinfection. For purpose, novel demo-scale plant was designed, implemented test evaluate capability proposed system provide an effluent European reuse regulatory framework. addition, carbon-sequestration energy analyses were conducted assess sustainability approach. research confirmed that UASB rector be employed biogas production (2.5 L h−1) recovery from organic matter degradation, but its requires further steps reused AnMBR complied class A standards E. coli, boasting concentration 0 CFU 100 mL−1, nearly negligible TSS levels. However, reduction BOD5 (35 mg L−1) required reach A. CWs efficiently produced below 10 L−1 close L−1, making suitable meeting standards. Furthermore, demonstrated significantly higher efficiency compared systems. Nonetheless, inclusion UV disinfection unit after attain B
