  • Seawater desalination for methanex

    Methanex has a large methanol production facility in Punta Arenas, Chile. In this region of the world, fresh water is not available, and the facility requires seawater desalination to provide drinking water and process water. When the facility underwent renovation and expansion of their facilities, Aqua-Chem ICD provided a total of five (5) new Once through Multi-stage Flash plants. The ...

  • Low-pressure desalting membranes for seawater

    The Long Beach Water Department (LBWD), similar to many Southern California utilities, have been facing the issue of decreased potable water supplies.  Because of its location, the City of Long Beach is ideally situated to take advantage of desalinated seawater as a source of drinking water.  However, the primary barrier to seawater desalination has been its relatively high cost as ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Environmentally sound desalination at the Perth Seawater Desalination Plant

    AbstractWater scarcity is recognized as a significant problem in Australia and throughout the world. Yet the demand for fresh water continues to grow, driven by the need for drinking water to satisfy the world’s growing population, changing weather patterns, an increasing need for water for agriculture and industry and the concentration of populations in urban areas that lack sufficient fresh ...

  • Seawater desalination using forward osmosis process

    This study aims to evaluate the feasibility of the forward osmosis (FO) process for seawater desalination. The leakage of boron from the seawater into the draw solution was also studied. According to the WHO guideline, the maximum permissible limit of boron in drinking water is 2.4 ppm. Preliminary results of boron rejection by forward osmosis membrane were found to be 60–70%. ...

  • High performance boron removal from seawater by two-pass SWRO system with different membranes

    Boron in the desalinated water produced by the seawater reverse osmosis (SWRO) system is one of the most challenging issues for drinking or irrigation water uses. In recent years, many post-treatment methods and designs for boron elimination have emerged and attracted lots of attention, but only a few cases have demonstrated high performance and economic efficiency. The main aim of this work was ...

  • Sustainable power and innovation provide clean drinking water and energy

    In many areas in Kenya, access to clean drinking water is lacking. About 88% of the population must travel long distances to get to the nearest source of clean water or is forced to drink contaminated water. Children in particular suffer from waterborne diseases. Systems Provide Energy-Independent Water Treatment To try to provide a long-lasting solution for the drinking water needs ...

  • Impact of over-pumping and sea level rise on seawater intrusion in Gaza aquifer (Palestine)

    Seawater intrusion is considered as one of the main processes that degrade water quality by raising salinity to levels exceeding acceptable drinking water standards. Over-abstraction is the main cause of seawater intrusion. Moreover, climate change and sea level rise speed up seawater intrusion. This paper presents the development of a coupled transient finite element model for simulation of ...

  • A novel super-cooled humidification?dehumidification system driven by thermal vapour compression unit for seawater desalination

    The current study presents the concept of a novel seawater desalination system that is configured by a humidification?dehumidification unit based on the vapour-compression process (HDDTVC). The coupled refrigeration unit employs the thermal compression of vapour by a jet-ejector. The new technical idea of proposed desalination system depends mainly upon the creation of a super-cooled temperature ...

  • Drinking Water Sources, Sanitation and Safeguarding Desalination: a critical element of water solutions for the 21st century

    In the face of climate change and the water needs from a growing world population, the use of seawater or brackish water through desalination has increased in importance. The energy efficiency and production costs for desalination plants have been markedly improved. Recent techniques have made it possible to acquire reasonably cheap desalinated water from plants that are fully powered from wind ...

  • Strategy of deriving 'wealth from waste' from concentrated brine of desalination plant

    Research and technological developments are being pursued vigorously all over the world to reduce the cost of desalinated water. Thermal and membrane-based desalination processes are very well known and plants are being operated to augment the demand of fresh water essential for drinking in water-scarce countries and to sustain the industrial processes. Any further improvement in energy reduction ...

  • Energy consumption and greenhouse gases emissions from the use of alternative water sources in South East Queensland

    Between 1999 and 2007, several successive years of severe drought put South East Queensland's water supply under immense pressure. The decision was taken in 2005 to build a seawater desalination plant and three water recycling advanced treatment plants as part of a large investment plan to secure the region's potable water supply. The infrastructure built and commissioned in the past 3 years has ...

  • Aruba promises the best water

    Aruba is a Caribbean Island located eighteen miles off the coast of Venezuela. The Island is extremely arid, with no natural fresh water source available. The Island is dependent on seawater desalination to meet its entire potable water requirements. An Island population of approximately 80,000 and a thriving tourist industry of over 100,000 visitors annually, demand a reliable supply of potable ...

  • Ensuring Water Quality in Africa

    Water is essential for life, and “access to safe water is a fundamental human and, therefore, a basic human right.” With this statement and his address on World Water Day in 2001, United Nations Secretary-General Kofi Annan put a spotlight on what continues to be a global problem: clean water. This year completes the UN “Water for Life” international decade for ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
