The present invention introduces a novel design for a water treatment unit. This design has two features, i.e. it can be used in its portable scale for domestic and rural areas such as the villages with minimum power consumption. The unit can be operated using one solar cell and that will eliminate the need for general electrical power source. This portable unit is essential in times of flooding, chemical spillage disasters, remote areas with polluted wells and many applications. The other approach is using the design in industrial scale (air-stripping, oxidation and adsorption) in industrial water treatment units. Such technology is effective because it brings three completely water treatment techniques in one unit that works effectively (time effective and efficiency effective) to remove chemical contaminants from water.
