Feasibility of nano-filtration for desalinization of saline/seawater used for irrigating vegetable crops under Qatar conditions

Water and arable land scarcity in the Gulf Cooperation Council countries necessitates growing vegetable crops in the greenhouses using desalinated water. There are a number of water desalination technologies to augment fresh water supply. These technologies have different energy consumption rates and variable costs to produce fresh water and brine. It is therefore necessary to compare these technologies for energy use efficiency and cost effectiveness to desalinate saline water.
