Investigation on the hydrodynamics of a circular crossflow membrane filtration for purification of drinking water

With increasing frequency and intensity of disasters reported around the world, no doubt the developing countries would suffer considerable damages such as environmental, infrastructure, economy, population displacement, etc., compared to the developed countries. It is well known that in the events of emergency situations, e.g. natural disasters, one of the most basic requirements for human survival is the supply of clean and safe drinking water. However, it is impossible to supply when the facilities and infrastructures required are not functioning effectively. Hence, there is an urgency to develop a decentralized water treatment system to answer such problems in the aftermath of disasters, which undoubtedly require immediate response while waiting for aid to arrive. In order to address these issues, experiments involving contaminants which are commonly found in natural waters (e.g. clay, humic acid, and bacteria) were carried out using commercially available microfiltration (MF) and ultrafiltration (UF) membranes.
