Egypt’s Water Crisis – Recipe for Disaster

By | | , , ,
41 Comments

Egypt has been suffering from severe water scarcity in recent years. Uneven water distribution, misuse of water resources and inefficient irrigation techniques are some of the major factors playing havoc with water security in the country. Egypt has only 20 cubic meters per person of internal renewable freshwater resources, and as a result the country relies heavily on the Nile River for its main source of water. The River Nile is the backbone of Egypt’s industrial and agricultural sector and is the primary source of drinking water for the population. Rising populations and rapid economic development in the countries of … Continue reading →

English poet W.H. Auden once said, “Thousands have lived without love, not one without water,” and how true that is. Water is what keeps us alive and sustains us. Why, then, do we have such a problem keeping water clean, and what does water pollution do, not only to us but to the environment? Let’s delve into the subject of water pollution so we can better understand it and its effects on the whole world. Water Pollution Facts Water pollution is caused when a toxic substance gets into the water supply, whether that be a river, ocean, or the underground … Continue reading →

تعاني مصر في السنوات الاخيرة من شح شديد في المياه و يعد توزيع المياه غير المتكافئ و اساءه استخدام موارد المياه وتقنيات الري غير الفعاله بعض العوامل الرئيسيه التي تلعب دورا مدمرا للأمن المائي فيالبلاد. يعد نهر النيل شريان الحياة في مصر حيث  يغطي متطلبا ت الزراعة و الصناعه و هو المصدر الرئيسيلمياه الشرب للسكان. ان ارتفاع معدلات النمو السكاني و التنمية الاقتصادية السريعة  في دول حوض النيل  بالإضافة الى التلوث و التدهور  البيئي آخذُ باستنزاف الموارد المائية في مصر.  و تواجه مصر   عجزا مائيا يقدر  بسبع بليون متر مكعب سنويا .وفي حقيقة الامر فإن الامم المتحدة قد حذرت من نفاذ … Continue reading →

Sustainable Wastewater Management: Why Solid–Liquid Separation is the Quiet Hero of Water Conservation

By | | ,
Leave a comment

Water is the resource that touches every part of the modern economy — yet it is also one of the most mismanaged. According to UN estimates, over 80% of the world’s wastewater is released back into the environment without adequate treatment. In water-stressed regions across the Middle East, North Africa, and beyond, that statistic is not just an environmental concern; it is an existential one. As industries expand and populations grow, the question is no longer whether we treat wastewater, but how efficiently and sustainably we do it. At the heart of nearly every effective wastewater treatment process lies a deceptively simple principle: separating … Continue reading →

Best Practices for the Operation and Maintenance of Seawater Desalination Plants

By | | ,
Leave a comment

Seawater reverse osmosis (SWRO) desalination has become one of the most widely deployed technologies for securing potable water in water-scarce regions. Its rapid expansion is driven by technological maturity, modularity, and continuous improvements in energy efficiency. Despite these advances, the long-term performance of desalination plants is still strongly dependent on operation and maintenance (O&M) practices rather than on design alone. Extensive research has demonstrated that fouling, scaling, and operational instability remain the dominant causes of performance decline in full-scale SWRO plants, leading to increased energy consumption, reduced permeate quality, and higher life-cycle costs [1–3]. The global desalination sector has evolved … Continue reading →

The Reuse of Greywater: Insights

13 Comments

Greywater includes water from showers, bathtubs, sinks, kitchen, dishwashers, laundry tubs, and washing machines. The major components of greywater are soap, shampoo, grease, toothpaste, food residuals, cooking oils, detergents, hair etc. In terms of volume, greywater is the largest constituent of total wastewater flow from households. In a typical household, 50-80% of wastewater is greywater, out of which laundry washing accounts for as much as 30% of the average household water use. The key difference between greywater and sewage (or black water) is the organic loading. Sewage has a much larger organic loading compared to greywater. The Importance of Reuse … Continue reading →

Litani River: A Sorry State of the Affairs

The Litani River, the largest river in Lebanon, faces a multitude of environmental problems. Due to decades of neglect and mismanagement, the river has become heavily polluted. The main contributors to the degradation of Litani River are industrial pollution from factories and slaughterhouse, untreated sewage, chemicals from agriculture runoffs and disposal of municipal waste. The pollution has reached such a level where it is obvious to the human eye and causing serious health issues for people drinking its contaminated water. The Litani River is a source of income for many families who use it in summer for many recreational activities; … Continue reading →

Water Crisis in Refugee Camps

The refugee crisis has hit record heights in recent years. According to the UNHCR, as of the end of 2019 there were approximately 79.5 million refugees worldwide. This is a significant increase from a decade ago, when there were 37.5 million refugees worldwide. Syria’s ongoing civil war, with 7.6 million people displaced internally, and 3.88 million people displaced into the surrounding region and beyond as refugees, has alone made the Middle East the world’s largest producer and host of forced displacement. Adding to the high totals from Syria are displacements of at least 2.6 million people in Iraq and 309,000 … Continue reading →

Trifluoroacetic Acid (TFA): An Emerging Threat to Water Resources and Drinking Water Safety

By | | , ,
Leave a comment

Trifluoroacetic acid (TFA) has emerged as one of the most widespread and persistent fluorinated contaminants detected in the environment. As an ultra-short-chain member of the per- and polyfluoroalkyl substances (PFAS) family, TFA exhibits exceptional water solubility, high mobility, and extreme environmental persistence. Unlike legacy PFAS such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), TFA is primarily generated through the degradation of fluorinated refrigerants, pesticides, pharmaceuticals, and industrial chemicals. Recent monitoring studies have revealed its increasing occurrence in rainwater, groundwater, surface waters, drinking water, food products, and even human serum. This review aims to summarize current knowledge regarding TFA sources, … Continue reading →

The Role of Dissolved Gases and Ionic Composition in Reverse Osmosis Desalination

By | | ,
Leave a comment

As global water stress intensifies, seawater desalination has become one of the cornerstones of water security in arid and semi-arid regions. From the Gulf countries to the Mediterranean basin, Australia, and parts of North America, desalination plants now produce tens of millions of cubic meters of drinking water every day. Reverse osmosis (RO) has emerged as the dominant desalination technology due to its increasingly competitive energy efficiency and the continuous improvement of membrane performance [1]. However, beyond traditional operational parameters such as salinity, pressure, and recovery rate, one critical factor often remains underestimated: seawater temperature. Its influence extends far beyond … Continue reading →

Aquifers are of tremendous importance for the MENA as world’s most water-stressed countries are located in the region, including Kuwait, Qatar, UAE, Palestine, Saudi Arabia, Oman, Iran, Lebanon and Yemen. However, aquifers in MENA are coming under increasing strain and are in real danger of extinction. Eight aquifers systems, including those in MENA, are categorized as ‘over stressed’ aquifers with hardly any natural recharge to offset the water consumed.   Aquifers in MENA Aquifers stretched beneath Saudi Arabia and Yemen ranks first among ‘overstressed’ aquifers followed by Indus Basin of northwestern India-Pakistan and then by Murzuk-Djado Basin in North Africa. The Nubian Sandstone Aquifer … Continue reading →
