Determinants of wastewater treatment expenditure of Austrian communities
Wastewater treatment services are bound to rather strict environmental regulations. However, as the broad range of wastewater expenditure of communities shows, there is room for discretionary policies of communities. The current paper explores wastewater treatment expenditure of Austrian communities by employing a cross-section econometric model. To a significant extent, demographic, geographic ...

What Is Wastewater Treatment?
Each and every day, most people worldwide create wastewater. Whether cooking or bathing, washing clothes or using the lavatory, people are constantly creating wastewater with little consideration of where it goes - and how exactly it is returned to rivers and seas, often cleaner than it was coming in. Modern wastewater treatment is a much needed spot of good news in the environment. What most ...

Immobilization of horseradish peroxidase on silane-modified ceramics and their properties: potential for oily wastewater treatment
Horseradish peroxidase (HRP) is proved being effective in eliminating oil from aqueous solutions, but the elimination is expensive because free HRP can not be reused. In present work, HRP was successfully immobilized on cordierite porous ceramics support with a novel method of N-β-aminoethyl-γ-aminopropyl-trimethoxysilane modification and glutaraldehyde activation. Under the optimized immobilized ...

EPA Provided Quality and Timely Information Regarding Wastewater after Hurricane Katrina
EPA provided quality and timely information regarding wastewater to States, wastewater treatment facilities, and the general public. The damage to the wastewater treatment facilities and their collection systems created a potentially critical health concern due to the possibility that people living in these communities would be exposed to raw sewage. Due to the risk of serious illness associated ...

Estimating the costs of collective treatment of wastewater: the case of Walloon Region (Belgium)
This paper contributes to a better understanding of costs for collective wastewater treatment in the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents are modelled. Considering investment as well as exploitation costs, the model includes not only wastewater treatment plants but also collector and sewage networks in an integrated approach at the technical ...

Corrosion resistant FRP reduces maintenance issues for water and wastewater treatment and control
At this Wastewater Treatment Plant in Glendale Heights, IL, an aluminum slide gate had to be forced open using a front-end loader and a chain after seizing in place due to inevitable corrosion. The corrosive bond was so severe that the chain snapped upon the first attempt. The water and wastewater treatment and control industry is a prime example of how constant exposure to toxic elements can ...
