Environmental Impacts of Seawater Desalination

Desalination is a process that removes salt and minerals from seawater and turns it into a potable resource. It is extremely helpful in areas experiencing rising water demands due to water scarcity, droughts, growing populations and increased water consumption. With the ocean covering most of the Earth’s surface, seawater provides a sustainable, long-term solution to a problem that won’t soon dissipate. By 2015, 18,000 desalination plants had cropped up worldwide, producing 22,870 million gallons of fresh water per day. Experts believe desalination, coupled with future advancements in technology, could be the key to establishing drought-proof communities worldwide. A clean source … Continue reading

MBBR Technology in Wastewater Treatment

Moving bed biofilm reactor (MBBR) is a biological technology used for wastewater treatment process suitable for municipal and industrial application. Another common name is moving bed film reactor. It was invented in the 1980s. MBBR offer an economical solution for wastewater treatment. STP MBBR technology is the use of a moving bed biofilm reactor in sewage treatment plants. MBBR wastewater treatment system enables efficient results of the disposal using low energy. The technology is used to separate organic substances, nitrification and denitrification. MBBR design is made of an activated sludge aeration system. The sludge is collected on the plastic carriers … Continue reading

Water Crisis in Gaza

Gaza Strip has been enduring constant Israeli bombardment for many years which has resulted in severe damages to its infrastructure and to its citizens. However the real risk is Gaza’s lack of usable water.  The only natural source of fresh water in Gaza is a shallow aquifer on the southern part of its coast; 90 to 95% of which is not safe for drinking because of neighboring seawater, sewage, and runoff from agriculture. Even though most of it is not fit for consumption, residents have no other choice but to resort to using it. UN hydrologists have indicated that current extraction … Continue reading

The Promise of Bioremediation

Ecosystems are permanently challenged with the abundant release of toxic compounds into the environment due to a wide range of anthropogenic activities. Apparently, contamination with oil spills and oily waste disposal are a major global concern since it’s extensively damaging the biodiversity, threatening the public health and has severe ecological and socioeconomic consequences. For example, in 1989, thousands metric tons spell of crude oil in Alaska, led to a massive loss in the marine life as well as several long-term environmental impact. Minor oil spills and non-point oil contamination are no less threats to public health, biodiversity and environment. Awareness of … Continue reading

Desalination Outlook for MENA

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

Hurdles in Domestic Water Conservation and How to Overcome Them

There is no doubt that we are spoilt in the developed world: We use far too much water, and we really should be doing something about it. The problem is that we live in houses that are already predisposed to wasting water. Granted, these days, if you buy a new home, it should be environmentally sound with the latest domestic water conservation strategies in place. However, what if you live in an older house or in a more modern one that has been poorly maintained? This article sheds light on where you are using the most water and how you … Continue reading

Climate Change Impacts in the Levant

Many countries in the Levant — such as Palestine, Lebanon, Jordan, and Syria — are afflicted by water scarcity, weak institutional and governmental resource management, high food import dependency and fragile economies –  all coupled with increasing populations and demand. According to the recent reports of the Intergovernmental Panel on Climate Change (IPCC) the Arab World will be witnessing hotter and drier conditions with extensive droughts causing severe water shortages that will have dire impacts on agriculture and livelihood. Farmers in the Arab world for centuries have been addressing adaptation and resilience issues through farming, water management and environmental degradation. Global … Continue reading

Tips for Hot Water Conservation in Households

With the drop in temperatures and persisting cold weather in many Middle East counties, use of hot water at home, offices, commercial centers, educational buildings and institutions have increased many folds. In winter, heating water for showers, laundry and washing makes up more than a third of an average household’s water and energy use, so it is important to heat water efficiently and conserve the water and energy. This is now essential as the cost of both electricity and water are going to rise in the near future, as in Bahrain, and consumers have to pay the part cost of these … Continue reading

Sustainable Urban Drainage Systems in Middle East: Benefits and Opportunities

With changing weather patterns of frequent and intense rainfall, regions in the Middle East are struggling to cope with the influx of rain and stormwater runoff that often flood roads and residential areas. While a good network of surface drainage systems enforced with concrete, pipes and manholes may alleviate the situation, city planners can now adopt the use of more sustainable and environmentally beneficial methods to decrease urban flooding in the Middle East. This technique of utilising natural drainage systems to improve water management is also referred to as Sustainable Drainage Systems (SuDS). Different types of SuDS: Detention ponds, green … Continue reading

Irrigation Systems in the United Arab Emirates

Driving down the streets of Dubai, one cannot ignore the large puddles of water that cover the side of the streets and sidewalks. These puddles, which are the result of attempted irrigation of green patches and plants, are a big waste. As a result, a very important question comes to mind: Does the UAE have that much water to spare?  Water in the UAE is in very short supply. The United Arab Emirates is one of the top 10 most water-scarce countries in the world, and has one of the highest per capita water usages globally. With 550 liters per person per … Continue reading

Unending Benefits of Wetlands

Wetlands are wonderful for numerous reasons but these wonders weren’t always known to man and it was often common to overlook the importance of this distinct ecosystem. The mention of a wetland used to bring to mind images of murky, mosquito-riddled swamps or unused lands that needed to be developed into a space which would be more useful to humankind. Wetlands were grossly undervalued which led to loss of many and provoked the Convention on Wetlands to be signed in Ramsar, Iran in 1971. The Ramsar Convention still serves as an international wetland conservation movement and currently holds over 160 nation … Continue reading
