Desalination is a water treatment process that separates salts from saline water to produce potable water. The desalination process uses large amount of energy to produce pure water from salt water source. Salt water is fed into the process, and the result is an output stream of pure water and another stream of waster with high salt concentration. Desalination techniques are mainly classified into two types: Processes based on physical change in the state of the water, and Processes using a membrane that employ the concept of filtration. There are more than 15,000 industrial-scale desalination units worldwide, with combined capacity exceeding … Continue reading →

Insights into the Survey The questionnaire covered household consumption habits, food waste and other household waste, and awareness of … Continue reading →
Water pollution has become a major concern worldwide, especially in developing countries where around 3.2 million children die each year as a result of unsafe drinking water and poor sanitation. Access to adequate wastewater treatment facilities in the developing countries is very limited. For example, only 209 of India’s 3,119 towns and cities—less than one in ten—have even partial sewage systems and treatment facilities. As a result water bodies in developing nations are often used as open sewers for human waste products and garbage, which is evident at the Ganges River in India which receives over 1.3 billion liters of domestic waste, … Continue reading →
The United Arab Emirates is among the top water-scarce countries in the world. However the country has one of the world’s highest per capita water consumption of 550 liters per day. The country is experiencing a rapid increase in population which has in turn resulted in huge demand for water. In 2009, the total water demand in UAE was estimated at 4.5 billion m3 (BCM) which was met by groundwater (72%), desalinated water (21%) and retreated water (7%). Water consumption in UAE is primarily divided among three sectors: Private households Agriculture Industries Private Household Sector This sector accounts for about … Continue reading →
