New Installation: Alkalinity in Drinking Water

New Installation: Alkalinity in Drinking Water

The recently installed alkalinity analyser: the new 2026 Process Analyser Metrohm Australia recently installed the 2026 analyser to monitor the alkalinity concentration in water supply. High alkalinity concentrations in drinking water cause scale deposition in the water distribution system. As a consequence this scaling entails rather extensive and costly maintenance...

Steam circuit monitoring in power plants

Lowering costs and corrosion in one easy step Steam circuit monitoring in power plants The use of amines to control pH levels in water-steam circuits is a common practice. By controlling the pH, corrosion can be limited which in turn lowers down time. Minimising the cost of reagents By monitoring...

Corrosion monitoring for industrial cooling systems

Minimise downtime by monitoring corrosion inhibitors on-line. Copper is widely used for piping in industrial cooling water systems due to its heat transfer properties. Unfortunately, it is highly susceptible to corrosion. Corrosion can cause a loss of efficiency and eventually a failure of equipment leading to costly maintenance, replacement and...

Power Plants: Online analyser to monitor FAC and metal transportation: Ultra trace Fe and Cu

Flow accelerated corrosion (FAC) in power plants: Continuous online ultratrace analysis of Fe and Cu

Monitoring flow accelerated corrosion and metal transportation in power plants: Online ultratrace measurements of Fe and Cu In power plants, corrosion is the primary factor leading to costly and critical downtimes. The water-steam circuits in fossil and nuclear power plants are inherently prone to corrosion, as metal components are constantly...

Alkalinity in drinking water

Alkalinity in drinking water

Public water supplies are vital resources and rather costly infrastructures.  High alkalinity concentrations in drinking water cause scale deposition in the water distribution system. As a consequence this scaling entails rather extensive and costly maintenance issues for the municipalities. Keeping the alkalinity in the desired range and thus minimising maintenance...

Measuring multiple dissolved and total metals online simultaneously

Measuring multiple dissolved and total metals online simultaneously

More often than not measuring heavy metal concentrations online in a process can be particularly challenging. This is especially the case when the sample contains several metals that interfere with each other during the measurement. Measuring multiple dissolved and total metals online simultaneously: Metrohm Australia has developed a new revolutionary...
