Abstract:
Analyzing the scaling/corrosivity chemistries of industrial process water systems (i.e.:cooling towers) is a key factor in confirming that preventive protocols are adequate and being sustained. As well as ensuring the health of employees maintaining and exposed to those systems. Water, having a scaling factor, can lead to mineral layer formation and corrosion pitting. Those layers and pits can become a breeding point for the bacterium Legionella pneumophila through the process of biofilm formation. EPA and Centers for Disease Control regulatory agencies are focused on reducing the risk of Legionella outbreaks from all sectors of industrial and manufacturing water use activities. The role of an advanced transportable spectrometer can provide onsite water chemistry results for the monitoring of various industrial and production water matrices. Having the capability of attaining accurate results on location can allow for improved decisions on potential water quality concerns and impart scale-biofilm awareness. This advanced spectrometer analyzes the chemistry constituents of scaling/corrosion and employs a pioneering software that calculates the Puckorius, Langelier and Ryznar Scale Indices, as well as water aggressive index (AI). This presentation will introduce the advanced spectrometer and describe how the final reports can be utilized for predicting and balancing water chemistry scaling tendencies in ultra-pure water treatment, wastewater processes, boilers, heat exchangers and cooling towers. Thus, aid in preventing biofilm formation that can possibly harbor Legionella pneumophilia. Additionally, the spectrometer results can inhibit and predict scale/corrosion related problems that can become physically and monetarily detrimental to the water processes’ infrastructure.
