Desalination Applications

  • 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.

    Advanced water treatment equipments for desalination

    Areas that have no or limited surface water or groundwater may choose to desalinate seawater or brackish water to obtain drinking water. Reverse osmosis is the most common method of desalination, Sea Water Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. Because no heating or phase changes are needed, energy requirements are low in comparison to other processes of desalination, though still much higher than other forms of water supply (including reverse osmosis treatment of wastewater).

    Reverse Osmosis Water Testing

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important process for a wide variety of applications including: medical, laboratory, desalination, industrial wastewater, Deionized (Dl) pretreatment, and drinking water.

  • 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.

  • 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.

    Filtration solutions for pre-treatment for desalination industry

    In desalination plants it is of great importance for the operation of the entire plant that the pre-treatment of the water is good before the salt is to be removed. For reverse osmosis (RO) desalination plants a good pre-treatment is essential for avoiding membrane fouling, resulting in reduced water production and increased operational costs.

  • 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.

    Monitoring Raw Water Intake

    The Situation: Hydrocarbons in water intake used for municipal drinking water and desalination systems are commonly limited to 1 part per million. Problem: Naturally occurring organics in raw water are typically treated with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when some type of organic material is present but cannot differentiate between natural organics, such as algae or leaves and hydrocarbons. Solution: A fluorescence monitor can be configured for sensitivity to hydrocarbons, with no significant response to other organics. The TD-4100XDC has the highest sensitivity to hydrocarbons in raw water, has a low cost of ownership, and can be modified with Teflon, Monel, and other corrosion resistant materials for sea water environments.

  • Industrial water Ammonia & Arsenic removal from water

    Nitrogen is a nutrient essential to all forms of life as a basic building block of plant and animal protein. Nevertheless, too much of it can be toxic. The processes used for the removal of ammonium ions from drinking waters include ion exchange. PuriTech`s ION-IX system can be broken up into 4 distinctive zones with each zone operating continuously. The resin is initially loaded with the Ammonia ions (and partially calcium and magnesium)in the adsorption zone. As the ION-IX multi-port valve rotates, the resin that has been saturated with Ammonia ions (and some calcium and magnesium ions)moves into a one-bed displacement zone with softened water to ensure hard water does not cause precipitation within the multi port valve.
