Employing non-conventional water resources using treatment and recycling is considered as the main resource in addressing future water scarcity. Although non-conventional water recycling has been investigated in details in the literature, its impacts on irrigation-fertilizing systems have not been discussed using thermoeconomic analysis. In this case study, using a hydroponic greenhouse system...
Based on the fact that recycling of combined filter backwash water (CFBW) directly to drinking water treatment plants (WTP) is considered to be a feasible method to enhance pollutant removal efficiency, we were motivated to evaluate the genotoxicity of water samples from two pilot-scale drinking water treatment systems, one with recycling of combined backwash water, the other one with a convent...
This research examines the life-cycle water and nutrients usage of microalgae-based biodiesel production. The influence of water types, operation with and without recycling, algal species, geographic distributions are analyzed. The results confirm the competitiveness of microalgae-based biofuels and highlight the necessity of recycling harvested water and using sea/wastewater as water source. T...
The Medical Journal of Australia ISSN: 0025729X 16 March 2009 190 6 293-294 ©The Medical Journal of Australia 2009 www.mja.com.au Editorials the safety of water recycling, especially as, at face valu represent a backward step from John Snow’s mid discovery of the importance of keeping drinking wat separate. The obvious question is: is water recycling s There are different types of recycling, an...
On their journey over large land masses, water molecules experience a number of precipitation–evaporation cycles (recycling events). We derive analytically the frequency distributions of recycling events for the water molecules contained in a given air parcel. Given the validity of certain simplifying assumptions, the frequency distribution of recycling events is shown to develop either into a ...
RATIONALE The Amazon River is a huge network of long tributaries, and little is known about the headwaters. Here we present a study of one wet tropical Amazon forest side, and one dry and cold Atiplano plateau, originating from the same cordillera. The aim is to see how this difference affects the water characteristics. METHODS Different kind of water (spring, lake, river, rainfall) were samp...
We investigate the dehydration processes in subduction zones and their implications for the water cycle throughout Earth's history. We use a numerical tool that combines thermo-mechanical models with a thermodynamic database to examine slab dehydration for present-day and early Earth settings and its consequences for the deep water recycling. We investigate the reactions responsible for releasi...
