Removal of bromide and bromate from drinking water using granular activated carbon

by IWA Publishing  (Feb. 27, 2015)

Granular activated carbon (GAC) was used to remove bromide (Br−) and bromate (BrO3−) from drinking water in both bench- and pilot-scale experiments. The present study aims to minimize BrO3− formation and eliminate BrO3− generated during the ozonation of drinking water, particularly in packaged drinking ...

Application of laser-induced breakdown-detection as a sensitive detector for UF membrane surrogate challenge tests

by IWA Publishing  (Apr. 8, 2015)

Characteristics of ultrafiltration membranes with respect to the removal of nanoscale particles can be determined by surrogate challenge tests (SCTs). Key elements of a successful SCT are the selection of a suitable surrogate and a reliable quantification method. A major challenge when using nanoparticles as surrogates is their quantification in ...

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 ...

UltraPure water: systems for microelectronics

by Membrana  (Jun. 1, 2006)

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. ...

Ultrapure water – The standard for resistivity measurements of Ultrapure water case study

by SnowPure Water Technologies  (Mar. 2, 1998)

Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no ...

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 ...
