Providing drinkable potable water from saline or heavily polluted water using renewable energy is further explored. Solar desalination is an eco-friendly, accessible and affordable technology. We show that there is a direct relationship between and huge dependency on solar still daily distillate yield in the solar radiation intensity and the temperature difference between the condensing inner glass cover and the water. Hence, we hope to have drinkable water for all using solar power technology.

We investigated the effect of long exposure to sunlight (as practised by retailers and peddlers in Bauchi State, Nigeria) of commercial plastic-bottled drinking water. The levels of physical/chemical parameters were measured for five brands, and it was found that levels of pH, antimony, nitrates, and bisphenol A changed significantly as exposure time increased, thus highlighting the importance of proper monitoring of storage and retailing of plastic bottle products to safeguard consumer health.

Our work investigates the settling behaviour of natural granules applied in drinking water treatment plants. We show that these natural granules have a tendency to show a considerably large deviation in terms of their settling velocity; this is contrary to what many velocity prediction models assume. In the current work, we present and discuss the factors which contribute to the observed deviation in drag and settling velocity. It connects full-scale operations and research.
