The irrigation suitability potential of an effluent treated by a pseudo‐natural wetland

Abstract

The performance of a pseudo-natural wetland to purify wastewater for irrigation potential was explored in this study. To study the system's performance and the hazard level of the raw wastewater and treated effluent, several water quality parameters were chosen, including electrical conductivity (EC), total dissolved solids (TDS), sodium (Na + ), calcium (Ca 2+ ) and magnesium (Mg 2+ ). Four different sampling points (inlet, two intermediate points, and the outlet) were investigated in the study.According to the electrical conductivity, wastewater flowing to the wetland was classified as category four (C4), 'extremely high salinity' and thus unfit for irrigation. Both intermediate sampling points were in C3, whereas the outlet sampling point was in C1. According to SAR, 20% of the samples collected at the inlet were classified as 'very high sodium hazard' (S4), 45% as 'high sodium hazard' (S3) and 35% as 'medium sodium hazard' (S2). The findings of this study also demonstrated that the pseudo-natural wetland can be significantly effective in reducing pollution and providing suitable water for irrigation. Furthermore, the findings raise greater awareness of the importance of protecting and conserving these valuable resources, particularly in urban areas.

Isolation and Characterization of Bacteria with High Electroactive Potential from Poultry Wastewater

“…Fundamentally, wastewater is the most widely used substrate for MFC operations because of its large proportion of organic load and lack of cost. In particular, agro-food wastewater is ideal due to its high biodegradability [ 19 , 20 , 21 ]. The numerous electroactive and complementary non-electroactive microorganisms convert the chemical energy stored in the chemical components of wastewater or biomass into electrical energy [ 22 ].…”

Editorial

“…This system and others like it show great promise for enabling safe reuse of domestic wastewater in agricultural applications, and this is especially important in rural areas of developing countries that may lack both safely managed sanitation services and reliably clean and abundant water. Another approach to sourcing water for irrigation can be found in Mklimia's (2022) work, which assesses the potential of ‘pseudo‐natural’ wetlands to serve as treatment systems, enabling waters polluted by poorly managed onsite sanitation in urban and peri‐urban areas to also be reused in irrigation.…”
