Distilled water

A solar still is a simple desalination unit, but typical configuration is a sealed box with an angled glass top. Sunlight shining into the box heats water or liquid, causing it to evaporate. The moisture condenses on the relatively cool glass cover and runs down the sloped surface for collection. In

Solar distillation is one of the important methods of utilizing the solar energy for the supply of potable water to small communities where the natural supply of fresh water is inadequate or of poor quality, and where sunshine is abundant. Solar energy utilization in two different types of solar sti

The humidification–dehumidification process (HD) is an interesting technique adapted for water desalination when the demand is decentralized. This technique presents several advantages such as flexibility in capacity, moderate installation and operating costs, simplicity, possibility of using low te

The paper describes a fundamental investigation of the corrosion behaviour of Cu-Ni-Fe-Mn alloys, containing nominally 10% Ni and 30% Ni, in distilled water. The study involved exposure of specimens to distilled water (1.5–7 µS/cm) at 20–80°C with and without injected carbon dioxide. At 20°C upon in
