Alternative polymer-based filter media and ornamental plants in constructed wetlands (CWs) are a relatively unexplored field. These approaches have the potential to reduce construction costs enhance aesthetic appearance of CWs. This study evaluated for first time use as monoculture polyculture, well incorporation polyethylene terephthalate (PET) medium large-scale community HC (divided into 12 cells) treatment municipal wastewater. Duplicate cells were planted with monocultures Canna...

Partially Saturated Vertical Constructed Wetlands (PSV-CWs) are novel wastewater treatment systems that work through aerobic and anaerobic conditions favor the removal of pollutants found in high concentrations, such as rivers contaminated with domestic landfill leachate. The objective study was to evaluate efficiency PSV-CWs using monocultures polycultures

The aim of this 2-year study was to evaluate the influence bed depth (40 and 60 cm) on development tropical ornamental species (

The amount of total phenols and flavonoids the antioxidant activity leaf, stem, rhizome methanolic extracts from a commonly consumed Anemopsis californica under different storage conditions were investigated. Storage at 50, 25, 4, −20°C, protected or not light, during 180 days. inhibition elastase enzyme was also evaluated. results demonstrated that maintain approximately up to 97 95% stability in phenolic content activity, respectively, when stored 60 days −20°C dark. Additionally, these...

Three pilot-scale two-stage hybrid constructed wetlands were evaluated in order to compare their efficiency for total coliforms (TCol) and Escherichia coli removal analyze performances two 1-year periods of experimentation. System I consisted a horizontal flow (HF) wetland (CW) followed by stabilization pond. II was also configured with HF CW as first stage which then vertical (VF) second stage. III VF CW. In the year evaluation, HF–VF system most effective TCol (p < 0.05) achieved...

Tequila vinasse (TV) is a high-strength effluent generated during the production of tequila, with chemical oxygen demand (COD) concentration up to 74 g/L. In this study, treatment TV was evaluated in 27-week study two types constructed wetlands (CWs), namely horizontal subsurface flow (HSSFWs) and vertical upflow (VUFWs). The pre-settled neutralized diluted at 10, 20, 30, 40% domestic wastewater (DWW). Volcanic rock (tezontle) used as substrate Arundo donax Iris sibirica emergent vegetation....

Abstract This work proposes an innovative wastewater treatment system that consists of a constructed subsurface flow wetland planted with ornamental flowers high market value. In addition to the benefit water treatment, this cash crop provides profitable business by producing commercial can meet all biological and safety requirements in order be commercialized. characteristic makes it very valuable for application developing countries. Five different species plants were studied from...

The aim of this study was to evaluate the domestic wastewater treatment efficiency as well survivability commercially valuable ornamental plants in subsurface flow wetlands (SSFW) for (DWW) laboratory and pilot wetland studies. scale included five different species (Zantedeschia aethiopica, Strelitzia reginae, Anthurium andreanum, Canna hybrids Hemmerocallis dumortieri) that were evaluated horizontal cells. All survived during 6-month experimental period demonstrating high nutrient...

Tequila vinasse is a liquid waste generated during the production of tequila, an emblematic alcoholic beverage in Mexico. The objective this study was to carry out investigation on tequila factories located state Jalisco order know location state, characterization vinasses including different sizes, current treatment methods, and disposal practices as well impacts common disposal. Part information collected by applying questionnaire previously contacted (and physically located). For...

Vertical partially saturated (VPS) constructed wetlands (CWs) are a novel wastewater treatment system for which little information is known about its design parameters and performance under tropical climates. The objective of this study to evaluate the nitrogen removal process from domestic production ornamental plants (Canna hybrids Zantedeschia aethiopica) in VPS CWs at mesocosms scale. Nine CWs, with free-flow zone 16 cm cm, were used as experimental units. Three units planted Canna...

Remote sensing has emerged as a promising tool for monitoring water quality (WQ) in aquatic ecosystems. This study evaluates the effectiveness of remote assessing WQ parameters Cajititlán and Zapotlán lakes state Jalisco, Mexico. Over time, these have witnessed significant decline WQ, necessitating adoption advanced techniques. In this research, satellite-based data were combined with ground-based measurements from National Water Quality Monitoring Network Mexico (RNMCA). These sources...

In this research, we are reporting the treatment of tequila vinasse by a coagulation-flocculation process coupled with heterogeneous photocatalysis using two types titanium dioxide nanoparticles, i.e. (1) commercial and (2) nanoparticles synthesized sol-gel. The efficiency in elimination phenol, which is one most harmful contaminants vinasse, was also included evaluation process. were annealed air at 400°C for 1 h characterized X-ray diffraction, transmission electron microscopy,...

The aim of this study was to evaluate the development and effect Heliconia latispatha in pilot-scale constructed wetlands (CWs) for treatment pig wastewater mixed with domestic wastewater, using PET waste as filter medium, a tropical climate.
