The semiconductor industry has found that traditional analytical methods for complexed copper in wastewater are not fit for purpose. Complexed copper cannot be measured using ion-selective electrodes and colorimetry technology faces a number of severe challenges. Faced with the challenges of colorimetry, Samsung Austin Semiconductors (SAS) evaluated the MetalGuard™ analyzer for its potential to significantly improve safety and quality of measurements for copper wastewater streams.

Intelligent water treatment systems incorporate real-time sensing to ensure that their performance is optimized to avoid under- or over-treatment and that any deterioration in system performance is signaled to permit timely remedial intervention.

SafeGuard™ is an automated trace metals analyzer for monitoring municipal and industrial water and wastewater. The system provides real-time, multi-stream analysis for a range of trace metal contaminants. SafeGuard delivers accurate and reliable results (up to 1 ppb or ± 15%, whichever is higher) with a typical measurement time of fewer than 30 minutes.

MetalGuard™ is the first fully automated, online multi-stream analyzer for monitoring trace metal contaminants such as arsenic, chromium-6, selenium and more. The online analyzer provides high frequency real-time data on trace metals contaminant levels in less than one hour with sensitivity down to 1 ppb.

MetalGuard™ Arsenic is the first fully automated, online arsenic analyzer for monitoring drinking water arsenic levels. The online analyzer provides high frequency real-time data on arsenic contaminant levels in thirty minutes with sensitivity down to 1 ppb.

Aqua Metrology Systems has introduced an innovative and proprietary analytical method on their SafeGuard™ system that provides measurements of trace metals in 5 minutes without compromising accuracy levels.

Real-time data and analytical information from online instruments help utilities comply with water quality regulations. The complete article detailing how online water quality instruments are poised for growth was published in the March/April 2015 issue of World Water.
