conclusions the ppi-g2 dendrimer with end amine groups exhibited a positive impact on the removal of dominant bacterial isolated strains. therefore, it is possible to use these nanodendrimers as a safe and effective material for water disinfection in the future. results the most important isolated bacteria were escherichia coli 37 (48.7%), klebsiella oxytoca 12 (15.8%), proteus mirabilis 3 (4%)...

Development of one or more large-scale seawater desalination plants in the State of Texas will provide a sustainable source of drinking water and represents a key component of alternative water resources planning for the future. Planning and implementation of a seawater desalination plant represents a significant infrastructure project and requires positive action in the areas of funding, envir...

The collection of fog water is a simple and sustainable technology to obtain fresh water for afforestation, gardening, and as a drinking water source for human and animal consumption. In regions where fresh water is sparse and fog frequently occurs, it is feasible to set up a passive mesh system for fog water collection. The mesh is directly exposed to the atmosphere, and the foggy air is pushe...

In recent decades, problems with the provision of drinking water and sanitation services around the world have increasingly been addressed by attempts at privatisation, recasting clean water as an essentially economic, rather than public, good. This approach gained particular acceptance in Latin America, but with limited success. In order to address the full range of social, economic and enviro...

In some areas limited water resources combined with the fast growing population are leading to a crucial situation because of the increase in water demand. Besides, an estimated one billion people are living both without access to clean drinking water or electricity. Therefore, a stand alone photovoltaic-power based hybrid membrane desalination prototype has been designed to meet this challenge...

Due to industrialization and environmental effects the drinking water quality has been greatly affected in Pakistan. A number of industries are draining their waste containing heavy metals without any treatment in effluents. As a result of this practice almost all of the fresh water resources are getting contaminated, although the deep aquifer in most of the countries is still safe from contami...

The Danube is an international river passing partly through Serbia. The protection of the environment and sustainable use of water resources is a primary task that implies constant monitoring of the quality status and evaluation of ecochemical status of the water in the Danube basin. The investigation includes calculation of all-inclusive water quality by the Serbian water quality index (SWQI) ...
