The objective of this study was to evaluate the treatment efficiency of a gravel contact oxidation treatment system which was newly constructed under the riverbed of Nan-men Stream located at the Shin Chu City of Taiwan. The influent and effluent water samples were taken periodically for the analyses of pH, temperature, dissolved oxygen, total suspended solids, five-day biological oxygen demand...
Background and Objective: Wastewater treatment and stabilization always imposes costs and consequently a lot of energy on wastewater treatment plants. To achieve the purification and stabilization of as much sludge as possible, breaking complex components into simpler components is considered a critical step. Therefore, this study aimed to evaluate the feasibility of treating the produced sludg...
Introduction: Aerobic treatment processes with fixed growth has attracted attention of the engineers and designers of wastewater treatment due to the separation of organic materials in sewage and also to nitrification (conversion of ammonium to nitrate).The purpose of this study was to evaluate the performance of Submerged Biofilm Reactor to removal of organic matter (BOD and COD), turbidity an...
The Colorado River is a principal source of water for 40 million people and farmlands in seven states the western US Republic Mexico. river has been under intense pressure from effects climate change anthropogenic activities associated with population growth leading to elevated total dissolved solid (TDS) suspended (TSS) concentrations. Elevated TDS- TSS-related issues basin have direct negativ...
Textile wastewater contains substantial pollution loads in terms of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and heavy metals. Phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (AMATS) is well established environmental protective technique. A lab scale stud...
the aim of this study was the increasing of leachate quality using integrated membrane bioreactor (mbr). the reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the analysis of cod, biochemical oxygen demand (bod5), total suspended solids (tss), and total dissolved solids (tds) were performed in feed and filtrate, whenever the system reached steady stat...
This study investigated the chemical and thermal properties of faecal sludge from 10 dry VIP latrines in Bester’s Camp in the eThekwini Municipality, Durban, South Africa. Faecal sludge samples were selected at different depths and from the front and back sections of 10 VIP latrines during a manual emptying process. The samples were analysed for: moisture content; volatile solids; chemical oxyg...
As an alternative to the usage of axenic bacteria achieve microbially induced calcium carbonate precipitation (MICP), this study evaluates two non-axenic biomasses as self-healing agents. A fungi-based consortium (Yeast) and heterotrophic nitrifiers (HTN) were harvested from incubation agricultural side streams. The characteristics identified through flow cytometry, total suspended solids volat...
