Maturation ponds are used in rural and regional areas in Australia to remove the microbial loads of sewage wastewater, however, they have not been studied intensively until present. Using a combination of culture-based methods and quantitative real-time PCR, we assessed microbial removal rates in maturation ponds at four waste stabilization ponds (WSP) with (n = 1) and without (n = 3) baffles i...

The current paper assesses the reliability coefficients of fifty six low-cost, full-scale wastewater treatment plants, including nine different treatment technologies for wastewater reuse in aquaculture and agriculture in northeast Brazil. This was carried out with the aim to evaluate alternatives for sustainable wastewater reuse in communities experiencing water scarcity. The technologies eval...

The present work sought to detect the presence of Pseudomonas spp. at different stages of an effluent treatment plant using the Australian system of stabilization ponds, and to determine the susceptibility of those isolates to different antimicrobials. Thirty-four isolates of Pseudomonas spp. derived from effluent treatment station water samples were collected near the transfer ducts between th...

At Vidaråsen in Norway sewage from a community consisting of 160 people, including a dairy, a food processing workshop, a bakery and a laundry is treated using a pond/reed bed system. The system consists of sludge settlement, pre-treatment surface/vertical-flow constructed wetlands, a 5 m deep enhanced facultative pond, three stabilization ponds, a planted sand filter and finally two horizontal...

Waste stabilization ponds (WSPs) rely upon natural biochemical reactions for treatment and are used widely across the world. However, WSPs often fail to meet performance expectations due insufficient hydraulic performance. Installation of baffles can improve by increasing mean residence time, reducing dead zones, short circuiting, thus improving pond Theoretically, with ability sustain attached...

This research work proposes a mathematical optimization model for constructing two ponds (1. Facultative pond and 2. Maturation pond) provided in series. The uses concrete volume as its objective minimization function. There were decision variables; the first was detention time (DT) second list number of baffle walls (NBW) both ponds. constraint parameters include fecal coliforms biochemical ox...

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...

Abstract Waste stabilization pond (WSP) systems exist in many countries affected by climate change causing increasing demand for irrigation water. There is little long-term experience with WSP Africa, and thus, this study provides a comprehensive investigation of Namibia. One its treatment trains was upgraded mechanical anaerobic pre-treatment, post-treatment compared to second train without up...
