ENVIRONMENTAL SCIENCE: Water Treatment Plants

The Environmental Science of Drinking Water

by Triatoma infestans after insecticide spraying has caused elimination efforts in the dry Chaco region to fail repeatedly. The sources and spatial extent that need to be considered to understand the reinfestation pattern and to plan a comprehensive control program were studied in 2 adjacent rural communities in northwestern Argentina from 1993 to 1997. The effects of external, residual , and p...

Optimal Design of the Water Treatment Plants

Upgrading Wastewater Treatment Plants Based on Reuse Demand, Technical and Environmental Policies (A Case Study)

Reclamation and reuse programs are an indispensable part of integrated water resource management, particularly in arid and semi arid regions. Yet, the feasibility of sustainable application not only is relied on design, operation and maintenance of wastewater treatment plants, but also could be influenced by the economical and environmental aspects of reuse demands. This study is aimed to illus...

Article Polyhydroxyalkanoate production on waste water treatment plants: Process scheme

This work describes the production of polyhydroxyalkanoates (PHA) as a side stream process on a municipal waste water treatment plant (WWTP) and a subsequent analysis of the production potential in Germany and the European Union (EU). Therefore, tests with different types of sludge from a WWTP were investigated regarding their volatile fatty acids (VFA) production-potential. Afterwards, primary...

Improving Water Quality by Coordinating Industries Schedules and Treatment Plants

Having a proper waste water treatment system is crucial for making a good use of water resources. Current regulations enforce some restrictions to the industries producing waste, according to the capacities of waste water treatment plants. However, these are usually not sufficient to ensure that these capacities are not exceeded. In this paper we present a coordination system that provides a mo...
