Microbial fuel cells (MFCs) are emerging as promising technology for the treatment of wastewaters. The potential energy conversion efficiencies are examined. The rates of energy recovery (W/m3 reactor) are reviewed and evaluated. Some recent data relating to potato-processing wastewaters and a hospital wastewater effluent are reported. Finally, a set of process configurations in which MFCs coul...

In this study, the treatability of rose processing wastewater was investigated by using electrocoagulation (EC) methods compared to classical chemical (CC) and Fenton application (FA) processes. High chemical oxygen demand (COD) and dissolved solids contents were detected in the wastewater. Among these treatment applications, it was found that the EC unit is the most effective treatment techniq...

The objective of this research was to modify an extended detention basin to provide batch treatment of stormwater runoff. An automated valve/controller was developed and placed on the outlet of a detention basin in Austin, Texas, which allowed the water quality volume to be retained in the basin for a preset length of time. The influent and effluent of the modified basin were monitored for tota...

Landfill leachate contains heavy organic pollutants, which pollute ground and surface waters. This dataset applied a newly-introduced catalyst, Cu/Mg/Al-chitosan, for a landfill leachate treatment during a catalytic oxidation. The data of chemical oxygen demand (COD) and colour removal from the leachate was reported as a function of reaction time (20-460 min). Economic evaluation data of the Cu...

This study examines the effects of erythromycin on activated sludge from two French urban wastewater treatment plants (WWTPs). Wastewater spiked with 10 mg/L erythromycin inhibited the specific evolution rate of chemical oxygen demand (COD) by 79% (standard deviation 34%) and the specific N-NH4+ evolution rate by 41% (standard deviation 25%). A temporary increase in COD and tryptophan-like fluo...

Abstract Mrázová and Neary (2017) introduce the notion of Demand Manifold which expresses relationship between elasticity curvature a demand function. They argue that this determines many important comparative static properties firm behavior. This paper gives necessary sufficient conditions for two functions to have same manifold so similar properties.

YORDANOV, D., 2010. Preliminary study of the efficiency of ultrafiltration treatment of poultry slaughterhouse wastewater. Bulg. J. Agric. Sci., 16: 700-704 Poultry slaughterhouses use relatively high amount of water with an average consumption of 26.5 L/bird during primary and secondary processing of live birds to meat. The used water contains proteins, fats, carbohydrates from meat, blood, sk...

The most important necessity for life is water. Shortage of clean & fresh drinking water leads to suffering. This is mainly contributed by generation of sewage waste mixed with the water bodies, due to unplanned urbanization and has largely contributed to the causing severe water pollution. Pollutants discharged in waste waters can be toxic to aquatic life and cause natural waters to be unfit t...

Coastal aquaculture can contribute to eutrophication of receiving waters. New technologies and improved management practices allow the aquaculture industry to be more sustainable and economically viable. Current practices, however, do not provide an additional use for effluent water. Nitrogen, phosphorus and other effluent compounds could be valuable plant nutrients. Inflow and effluent water f...
