The life of a high-purity water treatment project may be compared to rolling a boulder down a dome-shaped hill (1). The project gets rolling with a fairly small nudge. Once ¡t ¡s rolling, however, ¡t takes a great deal of effort (time and money) to change the direction or go back up the hill. The project to design, build, install, and commission the “E” high-purity water system at VLSI ...
Electrodeionization (EDI) has recently gained widespread acceptance by water treatment companies and end users alike for almost all applications requiring high-purity water. EDI has proven to be a reliable, cost-effective solution for both end users and water treatment companies. End users purchasing capital equipment can eliminate on-site chemical regeneration. Water treatment companies selling ...
It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology plays a special role atseveral ...

With the demand or higher efficiencies, lower maintenance and operating costs for boilwers and turbines, high-purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra upercritical boiler pressures and temperatures, require high-purity water that approaches quality levels at the theoretical levels. ...
A small industrial entrepreneurial company on the East Coast was considering using high purity water in the production of their high quality product. They were concerned the ‘larger’ water companies would not give the project the attention it deserved, and that the system may cost too much. They came to Applied Water Solutions, Inc. for the solution. Solution AWS met with the client and ...
The burgeoning electronics industry Electronics are the heartbeat of the products and services of many industries – including aerospace, communications, entertainment, defence, and health – and, as a consequence, the global electronics market is valued at US$1 trillion worldwide. The electronics market is a stage for intense competition, primarily among US and Asian firms. This in turn spurs ...
Electrodeionization (EDI) is the most common method to produce high purity water used for boiler feed water, microelectronic, and pharmaceutical industries. Commonly, EDI is combined with reverse osmosis (RO) to meet the requirement of EDI feed water, with hardness less than 1 ppm. However, RO requires a relatively high operating pressure and ultrafiltration (UF) as pretreatment which results ...
Companies in the utility business have a need for high purity water for their operations such as in diesel generator cooling systems and in turbine generator makeup water. Often, utilities can not depend on the city water as the quality is not pure enough and purchasing local water may be expensive. To gain operational and economic advantages, water purification equipment can be added. These ...

When planning an installation, the end user can choose to add the features shown to the standard R/O system. Hazardous Location Requirements Systems are built to Class 1, Group B, Division 1 standards ...
A cooperative water recycling effort between a major U.S. water/wastewater utility and a large oil refinery will provide significant benefits for both parties and will serve as a blueprint for future cooperative efforts between public agencies and industries.The East Bay Municipal Utility District (EBMUD), located in the eastern portion of the San Francisco Bay Area, is implementing the Richmond ...
Dynatec is engaged to provide a comprehensive water and wastewater treatment solution for an aerospace manufacturing process. Background Goodrich Aerospace was relocating a manufacturing facility that performs surface treatment for aircraft metal parts. The facility produces about 150,000 gallons per day of wastewater that contains hexavalent chrome, titanium, and other contaminants. The ...
High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens'cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is ...
IMEC (Interuniversity MicroElectronics Center) in Belgium is Europe’s largest independent research center. It focuses on microelectronics, nanotechnology, and enabling design methods and technologies for ICT (Integrated Circuit Technology) systems. IMEC’s research runs 3 to 10 years ahead of industrial needs. IMEC’s technology choices for process manufacturing steps used for project and process ...
MEGA has supplied High Purity Water Treatment EDI units as a part of novel membrane-only water treatment solution. The facility in the company ENERGY at Ústí nad Labem, Czech Republic, needed an update after tens of years of heavy duty. Ultrafiltration, reverse osmosis and EDI units were selected to process river water into ultrapure water. MPure™ EDI by MEGA has proven to be ...
The Facility The Esso refinery is located in Sriracha, Thailand approximately 50 miles south of Bangkok. Due to increased refinery demands, Esso embarked on a facility expansion to more than double the refinery’s production capacity. The Problem The expansion plan required additional high purity water to be used for boiler make-up. With the existing desalination units in disrepair, Esso ...
Electrodeionization (EDI) is the standard method of generating high purity water bypolishing reverse osmosis permeate. The technology utilizes electrical current toremove ionic impurities while continuously regenerating cation and anion exchange resins. EDI is utilized in all industries that require higher purity water than RO alone can produce including power, pharmaceutical, electronics, ...
Utilisation of waste heat is one of the ecofriendly ways to produce low-cost desalted water. Keeping this in mind, Low-Temperature Evaporation (LTE) desalination technology utilising low-quality waste heat in the form of hot water (as low as 50?C) or low-pressure steam (0.13 bar) has been developed to produce high-purity water (conductivity Keywords: LTE desalination, low temperature evaporation, ...
In the steam boiler industry, high purity feed water is required to ensure proper operation of steam generation systems. High purity feed water reduces the use of boiler chemicals due to less frequent blowdown requirements (reducing blowdown frequency by as much as a factor of 10). Lower blowdown frequency also results in lower fuel costs. Scale buildup is reduced due to a smaller concentration ...
