Water Harvesting and Recycling

Deep water recycling through time

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...

Optimal Groundwater Extraction and Water Recycling

Industrial Waste Water Treatment System for Water Recycling

Toshimasa Akamatsu Noboru Oda OVERVIEW: Many countries and regions around the world are facing threats of severe water shortages or degradation of the water environment resulting from factors such as explosive population growth, rising living standards brought about by economic progress, and increasing use of industrial water. Using the advanced technologies of water treatment systems, informat...

Bioinspired Breathable Architecture for Water Harvesting

Thuja plicata is a coniferous tree which displays remarkable water channelling properties. In this article, an easily fabricated mesh inspired by the hierarchical macro surface structure of Thuja plicata branchlets is described which emulates this efficient water collection behaviour. The key parameters are shown to be the pore size, pore angle, mesh rotation, tilt angle (branch droop) and laye...

Micro-Catchment Rain Water Harvesting Systems and fruit seedlings: Strategies and Research challenges

     The use of Rain-Water Harvesting (RWH) systems for fruit seedling planting in addition to helping to make optimal use of runoff and soil and water conservation, will also help the production of agricultural and horticultural products. Accordingly, this study has focused on the investigation of the effects of RWH systems on the growth of fruit seedlings and their establishment, especially i...
