Comparison of wastewater treatment performance: traditional vs. baffled horizontal flow constructed wetlands

International Journal of Phytoremediation, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 13

Published: April 7, 2025

This study investigated two lab-scale CW systems, traditional horizontal flow (HFCW) and baffled (BHFCW), as a treatment process in CWs filled with porous gravel planted Typha latifolia. BHFCW achieved average removal efficiencies of 88.65, 86.00, 84.17% for TSS, BOD5, and, COD, respectively. Meanwhile, HFCW, the these pollutants were 88.48, 81.07, 77.89%, The results demonstrated that is reliable alternative to enhance performance nitrogen compared HFCW. removals best among all units: 76.59, 86.39, 92.22% NH4+, NO3-, NO2-, Statistical differences observed when comparing effects between HFCW (p < 0.05). Nevertheless, 84.15% orthophosphate was successfully removed introduction baffles augmented path wastewater. 14% one-day reduction area HRT noted relative types used are suitable wastewater treatment. investigation type showed role absorption retention pollutants. In addition, could generate interest option.

Constructed Wetlands as a Decentralized Treatment Option for Domestic Wastewater: A Systematic Review (2015–2024)

Water, Journal Year: 2025, Volume and Issue: 17(10), P. 1451 - 1451

Published: May 12, 2025

Constructed wetlands (CWs) attempt to simulate the physicochemical and biological processes that occur within a natural wetland have been employed in recent decades for wastewater treatment. This work aims review use of CWs domestic treatment undeveloped or developing areas, including amount literature produced, type constructed wetland, vegetation, substrate, social benefits achieved, through qualitative methodology where different articles are collected from Scopus Web Science databases after strict revision by means PRISMA method (Preferred Reporting Items Systematic Reviews Meta-Analyses) CASP (Critical Appraisal Skills Program). A total 49 were selected, co-occurrence density maps obtained; following this, three main themes five keywords with highest correlation identified. The analyzed this exposes types not only hybrid, vertical, horizontal flow systems stand out, but also floating aerated wetlands, which present high removal efficiencies. Additionally, new substrate materials, such as olote, palm shells, coconut peat, ornamental plants usually used, Phragmites australis Thypha latifolia, discussed; however, studies vegetation has little studied potential be implemented areas silvicultural characteristics out: Duranta repens, Pennisetum pedicellatum, Pistia stratiotes. In conclusion, there is an advancement research these systems, configurations, substrates, treat wastewater; addition, opportunity continue studying installation at household level; compared other application mentioned above, its implementation requires greater challenge, since it compact design easy handling.

Sizing a System for Treating Effluents from the Mozambique Sugar Cane Company

Sustainability, Journal Year: 2024, Volume and Issue: 16(19), P. 8334 - 8334

Published: Sept. 25, 2024

The sugar industry must be managed in a manner that encourages innovation with regard to the waste generated throughout process. organic load of mill is high, as its potential pollute water bodies at various stages production process, including cooling bearings, mills, cane washing, bagasse and cleaning products. It therefore necessary identify treatment mechanisms not only reduce this but also return purer environment, combining reuse applications. objective study was analyze results physical chemical properties effluents principal technologies employed for remediation industrial wastewater from factories. Mozambique’s mills has high levels dissolved or suspended solids, matter, pressed mud, atmospheric pollutants. BOD/COD ratio low (<2.5), indicating need secondary or, more specifically, biological treatment. This can achieved through humid systems built stabilization ponds, resulting suitable agricultural irrigation. In work, an educational proposal been developed engineering students where they learn calculate optimize, among other parameters, natural compare it conventional
