VLSI chooses liqui-cel contactors over conventional vacuum tower for deaeration

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 ...

Combined ultrafiltration-electrodeionization technique for production of high purity water

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 ...

High purify water systems for utility use

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 ...

Conductivity Measurement in high purity water samples below 10 microsiems/cm

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 ...

VSEP improves industrial boiler performance and reduces blowdown frequency by a factor of ten

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 ...
