The wastewater treatment process is aimed to reduce pollution the appropriate level. An oxidation pond system can treat contaminants in wastewater. Oxidation ponds are use sunlight, bacteria, and algae This study developed an improved mathematical model a graphical user interface (GUI), called oxi-P GUI predict pond. correlation between dissolved oxygen (DO), chemical demand (COD), coliform as ...

The characterization of landfill leachate has been well established. However, its biodegradation properties have not been well reported. Therefore, this research was undertaken to investigate the biodegradability of semi-aerobic sanitary landfill and the ratio of the biological oxygen demand (BOD) to chemical oxygen demand (COD) BOD5/COD, COD fraction on leachate from Pulau Burung landfill Site...

Endotoxins are derived from gram-negative bacteria and are a potential respiratory health risk for animals and humans. To determine the potential for endotoxin transport from a large open-lot dairy, total airborne endotoxin concentrations were determined at an upwind location (background) and five downwind locations on three separate days. The downwind locations were situated at of the edge of ...

Abstract The majority of cities in the Saharan territory south Morocco utilize waste stabilization ponds (WSPs) for municipal wastewater treatment because their relatively low capital, operational costs, and minimal complexity. New national effluent quality regulations have been implemented Morocco, they will be applied to all systems. In this study, we chose three that are located area charact...

High-throughput microbial electrolysis cells (MECs) were used to perform treatability studies on many different refinery wastewater samples all having appreciably different characteristics, which resulted in large differences in current generation. A de-oiled refinery wastewater sample from one site (DOW1) produced the best results, with 2.1±0.2 A/m(2) (maximum current density), 79% chemical ox...

The improvement of rural living standards in developing countries and the continuous upgrading industrial economy have prompted diversification areas residential forms. Thus, an integrated sewage treatment process has gradually become mainstream technology for treatment. Numerous studies reported effects ecological wastewater Meanwhile, relevant technologies, evaluations, operating models yet t...

Wastewater treatment systems collect and treat sewage that includes microplastics (MPs). However, we are not aware of any studies on the occurrence distribution MPs in wastewater stabilization ponds (WSPs), which serve small communities worldwide. Here, characterized (~45 µm–5 mm) an aerated WSP serving ~500 houses adjacent lake. Putative were most abundant duckweed (Lemna minor) sludge (75 ± 2...

Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. As treatment proceeds in WSPs, algal growth increases and pH rises, this has lead to believe that P removal is mainly through sedimentation as organic P algal biomass and precipitation as inorganic P. In activated sludge t...
