desalination technology Applications

  • Desalination Thermal Multi Stage Flash Technology (MSF)

    Aquatech MSF ( Multi Stage Flash) Desalination technology was developed more than fifty years ago, and were some of the first to install large size MSF equipment plants in Saudi Arabia, a key market in desalination. With our depth of technological expertise and experience in operating plants, we are positioned to offer the best support in design optimization and rehabilitation of existing facilities. Uses low pressure steam as heat source Highly reliable, and simple to operate & maintain Simpler supply water pretreatment Minimum down time so, higher availability factor High purity product water Provides thermal energy efficiency similar to the MED process Operates at a top brine temperature <110 °C to minimize scaling and to prevent corrosion

  • Desalination Thermal Multiple Effect Distillation (MED)

    Aquatech’s Multiple Effect Distillation (MED) Desalination technology, using a spray film™ design, has been developed and improved over decades of in- house research and onsite experience of such systems worldwide to provide an environmentally friendly system to meet the global challenges of a reduced carbon footprint. Production capacity up to 10 MIGD (45,500 m3/day) in a single unit: Significantly lowers electrical consumption Design flexibility to use low to medium pressure supply steam Minimum down time and therefore a higher plant availability factor High purity product water Operates at a low top brine temperature (<70 °C) to minimize scaling and to prevent corrosion Allows use of lower cost but reliable and proven metallurgy Use of Thermo Vapor Compressor to increase efficiency

    Sea Water Intakes & Outfalls

    Desalinated sea water is a major water source for many countries. These facilities are often built with power generation plant and a major factor for all installations is reliability. This reliability starts with the sea water intake and regardless of the desalination technology (MSF, MED, RO) unplanned plant shut downs due to the ingress of hydrocarbons or a sudden jelly fish attack are absolutely unacceptable. The DESMI Oil Spill Response segment have many years experience in the design, manufacture, installation and commissioning of permanent oil boom and jelly fish net systems for a vast range of sea water intake systems. We have an impressive history of proven oil spill technology at various locations around the world including the harsh Middle East environment.

  • Water treatment research for pulp and paper industry

    Historically the pulp and paper industry has had little need for desalination and reuse – not least because the majority of production is located near water sources. Four things are changing this state of affairs: The move towards recycling means that production in mills located in “urban forest” areas is rising. These facilities face higher water costs than green forest located mills, and have a greater interest in water efficiency. The fastest growing market for pulp and paper is in China, where raw water sources are both limited and impaired, and water technologies which can address these challenges are at a premium.

  • Using evaporation to dewater Reverse Osmosis reject waste streams

    Reverse Osmosis (RO) technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected membrane) pass through the micropores in the membrane, yielding a purified water stream called the permeate. Larger molecules are retained by the membrane as well as a portion of the water that does not pass through the membrane. This concentrated stream is called the concentrate or RO reject.

  • Water treatment research for mining industry

    Securing a reliable supply of water for extraction, handling and transportation is vitally important to mining companies looking to expand their operations. These companies will go to great lengths to meet this need, running pipelines hundreds of miles long from desalination plants on the coast and treating wastewater that is conventional held in tailings ponds. Wastewater treatment technologies can recover saleable metal that might otherwise be lost and prevent environmental contamination from highly acidic effluent streams. Developing the infrastructure and technologies to meet these challenges in the mining industry is driving a market worth $11.9 billon.

  • Water treatment research for refining and petrochemicals industry

    Refining processes like distillation use high quality steam that must be generated from ultrapure water. Advanced wastewater treatment technologies will help the industry meet tough regulations concerning hazardous waste products from process operations. As the industry expands into water-scarce areas in India, China and the Middle East, marginal sources can help meet the demand for water. Desalination and reuse technologies will secure a reliable source of water and help the industry manage its water impact. Water technology suppliers have the opportunity to tap into a market worth $768 billion.

  • Water treatment research for food and beverage industry

    Direct reuse of wastewater in the product is not on the menu in the food and beverage industry, but the reuse of water for other purposes (e.g. washing) is now a priority. Most major F&B companies have made commitments to reduce their water consumption per unit of product, and reuse is an important part of the strategy for achieving this. Furthermore much of the growth of the industry is in emerging markets which typically have more limited, lower quality water resources than developed countries, creating water treatment challenges. In developed markets, emerging concerns about pharmaceutical by-products and other trace contaminants making their way into the product have lead to greater use of desalination technologies on the process water side. Value from waste propositions such as energy recovery, water reuse (not within the product) and materials recovery ensure that investment in water technology benefits the bottom line.
