Concerns about decreasing urban water supplies and environmental degradation caused by existing water infrastructure have prompted research on more resilient and long-term water delivery systems. Greywater reuse has been proposed to expand local water supply portfolios while minimizing stress on existing ecosystems and infrastructure. Researchers h...

Solar Desalination unit with three basins system used for groundwater treatment. The incoming rate of water was measured in Solar based Distillation collected water during the morning to evening (8:00 am to 6:00 pm). In the present study, Groundwater at Kaka-Nu-Tarapur, Gandhinagar was collected and characterized for physic-chemical parameters. The...

Nanotechnology plays an important role in current environmental practices for remediation of contaminants in environment. From last few years, nano-clay has found more attention because of its unique characteristics and properties. Clay and clay minerals are very important naturally occurring mineral playing key role in environmental protection. Cl...

This review paper mainly focuses on different types of solar still and highlights the passive solar still. It considers advanced modifications in the design and development of materials, single- and multi-effect solar stills with augmentation of different materials, energy-absorbing insulators, and mechanisms of heat and mass transfer to improve th...

In this present research work, theoretical modeling of single slope, single basin solar still integrated with evacuated tubes has been performed based on energy balance equations. Major variables like water temperature, inner glass cover temperature and distillate output has been computed based on theoretical modeling. The experimental setup has be...
