DESALT Electrodialysis Reversal (EDR) Equipment is the equipment of choice for the treatment of any kind of water, wastewater, chemicals, salts, and many more.
The Reverse Electrodialysis process utilizes electricity and special membranes to remove and concentrate impurities from water, making it suitable for the treatment needs of companies and in residential applications.
DESALT Electrodialysis Reversal (EDR) Equipment
DESALT Electrodialysis Reversal (EDR) Equipment is an advanced technology used for water, wastewater treatment, particularly in desalination processes and systems for chemical production.
DESALT EDR equipment utilizes electricity and membranes to remove salt and other impurities from water, making it suitable for consumption, irrigation, and many other industrial processes.
The Electrodialysis Reversal (EDR) technology is chemical free and features high recovery rates compared to traditional water treatment methods.
What Is Electrodialysis Reversal (EDR)?
Electrodialysis Reversal (EDR) is a membrane-based water treatment technology that works by applying an electric field to a stream of water.
The generated electric field separates ions from water, allowing for the removal of impurities such as salt and other minerals.
The process uses a series of alternating cationic and anionic, or bipolar membranes, creating a flow of ions that results in the removal of impurities.
Benefits of Electrodialysis Reversal (EDR)
One of the primary benefits of Electrodialysis Reversal (EDR) technology is its ability to remove impurities from water without the use of chemicals. This makes it a more environmentally-friendly option compared to traditional water treatment methods that use chemicals such as PAM, PAC, and chlorine;
EDR technology requires less energy compared to other desalination methods such as reverse osmosis because it works on very low pressure;
Electrodialysis membranes stacks are specifically designed for maximal efficiency and can be easily cleaned. The membranes should be replaced only every 7 to 10 years, mostly depending on the feed water and maintenance schedule;
Scaling and fouling potential are reduced thanks to the reversal function of the equipment, thus it avoids costly pre-treatment and hard chemical cleaning for the most difficult waters to treat.
Applications of Electrodialysis Reversal (EDR)
Electrodialysis Reversal (EDR) equipment technology is commonly used in desalination plants, particularly in coastal regions where access to fresh water is limited.
It is also used in industries such as pharmaceuticals, food and beverage, and electronics, where water quality is critical for production processes.
Finally, Electrodialysis Reversal (EDR) is often used in the chemical industry to concentrate components and increase the final product purity.
Electrodialysis Reversal (EDR) equipment is an effective process for desalination, providing high-quality water at a lower cost than other desalination methods.
DESALT Electrodialysis Reversal Equipment can remove up to 99% of dissolved salts from seawater, brackish water, and other sources. DESALT technology has been widely adopted in regions where freshwater is scarce, including the Middle East, North Africa, and parts of Asia.
Electrodialysis Reversal (EDR) systems can operate at a lower pressure than traditional reverse osmosis (RO) systems, reducing energy consumption and costs. EDR systems also require less maintenance than RO systems and have a longer lifespan.
Finally, Reverse Electrodialysis systems produce less brine waste than RO systems, making them a more convenient option.
DESALT Electrodialysis Reversal (EDR) equipment is also used for brine concentration, a process that involves removing water from a saline solution to increase the concentration of dissolved salts. Brine concentration is used in various industrial applications, including chemical production and wastewater treatment.
EDR systems are capable of achieving higher salt concentration levels than other concentration methods, including evaporation and crystallization.
The Electrodialysis Reversal (EDR) process can also concentrate brines with high levels of scaling and fouling potential, reducing the need for costly pre-treatment and chemical cleaning.
Acid and Base Production For Chemical Industry
DESALT EDR technology can be used to produce high-purity acids and bases, which are used in various industrial processes, including chemical synthesis, pharmaceuticals, and electronics.
Electrodialysis Reversal (EDR) process can produce high-purity hydrochloric acid, sulfuric acid, sodium hydroxide, potassium hydroxide, and many more.
EDR-based acid and base production can achieve higher purity levels than other production methods, including ion exchange and chemical precipitation. EDR can also produce acids and bases without the need for additional chemicals or reagents, cutting costs and wastage in comparison to traditional methods.
Finally, EDR can increase concentrations of any chemical with the correct membrane selection and recirculating design of the liquid treatment system.
