Achieving consistent low energy consumption in sea water RO based desalination plants using Lowatt® technology

Low Energy Consumption

Abstract Biofouling remains the single most important factor that increases energy consumption as time progresses in the operation of the Reverse Osmosis (RO) membrane system. One of the challenges with plant operation is that once a plant has been designed for certain energy consumption, it does not remain steady over a period. This is mainly due to biofouling and the inability to clean the membrane efficiently. In an effort to maintain healthy operational efficiency in terms of water production and energy consumption, differential pressure across the membranes should remain constant…

Digital Water Utility

Background: Many water utilities around the world have been suffering for years from underinvestment, alongside significant deterioration of the water system due to aging infrastructure and inadequate maintenance. Today, water utilities face additional challenges, such as increased water consumption coupled with a decrease in water sources due to extreme climatic events, pollution, and inefficient management of existing systems. Additionally, there is a need to enhance control and monitoring of all water systems to ensure a continuous supply of safe drinking water to the entire population. This challenge is even greater…

Sustainable Desalination

Water is often taken for granted, yet for many around the globe, it is a precious and increasingly scarce resource. As populations grow and climate change disrupts traditional water cycles, the availability of fresh water is becoming a critical concern. The World Health Organization reports that over 2 billion people live in countries experiencing high water stress. In response, the world is turning to the ocean, which covers over 70% of our planet, as a vast and largely untapped source of fresh water through the process of desalination. Desalination, the…

Tech's Role in Solving Water Crisis

As you leaf through today’s newspaper, the resounding message is crystal clear: we’re facing a dire water crisis, and the urgency to address it is palpable as time ticks away. India grew from merely 51 million tons (Mt) of food grain production in 1950/51 to over 314 Mt in 2022- a sixfold increase in production. What led to this remarkable outcome was the shift to science-led agricultural development, planner’s vigour and the dedicated effort of millions of farmers. This transformed India from an acutely food-scarce and food shortage nation to…

Grey Water Management and Natural Purification Processes

IntroductionGrey water refers to the wastewater generated from domestic activities, including water from bathrooms, kitchens and laundry. While it is typically contaminated, it is not as hazardous as black water (from toilets). In areas with high population density, such as the Lower Ganges Basin and other river basins, managing grey water presents a significant challenge. This article discusses the natural purification and settlement processes of grey water that exist within local ecosystems. The primary contaminants found in grey water include: Detergents and Surfactants: From laundry and dishwashing soaps, these can…
