Challenging Engineering Design and Ultra Pure Fabrication for the Semi-Conductor Industry

by Fabricated Plastics Limited  (Aug. 30, 2012)

Challenging Engineering Design and Ultra Pure Fabrication for the Semi-Conductor Industry The semi-conductor industry is one of the most demanding in terms of its requirements from suppliers. Only a few companies worldwide have the expertise, the facilities, the knowledge and the experience to be considered when new plant equipment is put out for ...

HF Pure Water visits the Middle East

by HF Pure Water  (Aug. 5, 2013)

HF Pure Water recently participated in the Water, Energy, Technology and Environment Exhibition held in Dubai, UAE. In speaking with numerous people that visited the HF Pure Water booth, it became apparent that there were limited opportunities for waste water treatment as many manufacturers simply dumped their wastewater into the ocean. This was ...

Electrodeionization - Ultrapure water

by SIMPEC Srl Societa Implanti Ecologici  (Sep. 29, 2011)

Continuous Electrodeionization Process The continuous electrodeionization process (CEDI),  is a system that uses ion exchange resins and electricity  for the production of ultrapure deionized water without chemical processes and without production stops. SIMPEC uses modular systems for the electrodeionization processes. The CEDI ...

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

by IC Controls  (Jan. 1, 2012)

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 ...

High Purity Boiler Water Production Using Municipal Wastewater at a Combined Cycle Gas-Fired Generating Station

by Eco-Tec Inc.  (Mar. 24, 2014)

Abstract The recovery of wastewater for industrial uses presents many challenges for the design and operation of water treatment equipment. Since the term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water, the water characteristics may have great variability. As such, the ...

Pure water pH measurement in low conductivity samples

by IC Controls  (Jan. 1, 2009)

Normally, pH measurements are made in water with 1,000 to 10,000 uS/cm conductivity. The conductivity conies from dissolved solids, typically, salts plus net acid or base which explains the exhibited pH. These dissolved substances are in the solution in ion form, which makes such solutions conducting. With 1,000 uS/cm conductivity of mobile ions ...

A Case for Point-of-Use RO Ultrapure Water Systems

by GE Water & Process Technologies  (Jan. 1, 2000)

ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of ...

Analysis of impurities in ultrapure water by dynamic reaction cell ICP-MS

by PerkinElmer, Inc.  (Oct. 28, 2009)

Ultrapure Water (UPW) is used for the cleaning of instruments and containers in trace analysis and for dilution of samples. The analysis of impurities in UPW requires increasingly lower levels of detection and higher instrument productivity. SEMI Standard F63-03091 specifies a maximum contamination for metals of 0.02-0.1 ppb for each element for ...
