Bacteria play an important role in oxidation and stabilization of organic and inorganic matterin wastewater treatment plant. This paper presents the development of mathematical model to study theeffect of chromium on heterotrophic bacteria in waste stabil... see more

This study assesses seasonal particle size distribution (PSD) dynamics inside a waste stabilization ponds (WSP) (Buguruni, Tanzania) to understand settling dynamics of wastewater particles with an interest in helminth eggs. Results indicate that particles... see more

Dissolved oxygen is an essential controlling factor in the performance of facultative and maturation ponds since both take many advantages of algal photosynthetic oxygenation. The rate of this photosynthesis strongly depends on the time during the day and... see more

Abstrak Kota Jakarta merupakan kota metropolitan yang tidak lepas dari permasalahan lingkungan seperti adanya timbulan air limbah domestik. Air limbah domestik di kota Jakarta salah satunya diolah dengan waste stabilization pond (WSP) dan dengan sist... see more

Plant macrophytes in wastewater treatment systems are important for providing various ecological and environmental benefits, e.g. detoxification and removal of toxic heavy metals. In this study, phytoremediation of four heavy metals (Cd, Cu, Pb and Zn) by... see more

Wastewater infrastructure is expensive to build and maintain, and there is a need to focus on improving and modernising existing infrastructure before large capital investments are made to service future population needs. Waste stabilisation ponds (WSPs) ... see more

Emerging global threats, such as climate change, urbanization and water depletion, are driving forces for finding a feasible substitute for low cost-effective conventional activated sludge (AS) technology. On the other hand, given their low cost and easy ... see more

Treatment in a wastewater stabilization pond (WSP) relies on natural purification processes, which can be sensitive to both location and climate. This study investigated the effects of three environmental factors, pH, dissolved oxygen (DO) and temperature... see more

Aim: This study aims to assess the entire process of septage management comprising regulation, operational procedures, finance, community involvement, and water quality analysis to maximize the initial and hugest human fecal sludge treatment called F... see more
