Abstract
Water scarcity is the lack of sufficient available water resources to meet water needs within a region. The world is facing nowadays this problem as a fatal problem, which needs to be solved to avoid as possible the next wars about water resources. Desalination of seawater is the appropriate solution for solving this problem. Fossil fuels are the main source used to get fresh water from water desalination. Although, fossil fuels are the main source, but it makes pollution, so renewable energies like solar energy and biogas are the upcoming new sources to achieve this goal.
The present work is devoted to study experimentally the effect of using solar energy and biogas on saline water desalination by using humidification dehumidification method. The present work is divided into two parts, the first part concerned with using humidification dehumidification method to produce fresh water from saline water by using two different types of humidifiers (packing humidifier and air bubble column humidifier), while the second part concerned with producing biogas from floating type fermenter and used as a heating source beside solar energy.
