Mine tailings ponds are challenging measurement environments. They are remote, exposed, chemically variable, and often difficult to access safely. Yet the data they produce can be critical to environmental compliance, water treatment decisions, and long-term tailings facility management. pH is one of the most important measurements in this setting. It is simple in concept, [...]
Key Take-Aways Nanocoatings can influence the properties of sensor reference junctions To achieve the desired effects, applying the nanocoating must consider electrolyte retention Use of nanocoatings to mitigate fouling of sensors shows promise but precise placement is required during the manufacturing process Details of Paper Title: Efficacy of Nanocoatings in Reducing pH Sensor Maintenance [...]
Maximizing Efficiency with Digital Water Analysis: The Role of the SensorFlex™ Platform in Mineral Processing and Metal Refining As an instrumentation technician in a mineral processing facility or hydrometallurgical plant, you’re no stranger to challenging environments. From abrasive materials to corrosive chemicals, ensuring accurate water quality measurements is essential for optimizing processes, maintaining compliance, and [...]
Anti-Coating Treatment for pH Sensors In many industries pH measurement is crucial to ensure the desired output of a process or to reduce its environmental impact. However, maintaining pH sensors can be costly especially where they are prone to scaling, coating and fouling thereby leading to inaccurate readings, decreased lifespan, and increased maintenance costs. [...]
Wood - A High Performance Material for Process pH Analysis Why would anyone consider a wood reference junction in a pH probe? Apart from use in furniture, building and some niche applications, wood may be considered an engineering material of years gone by. Wheels for cars are made from aluminum alloy, power boat hulls [...]
Key Properties of PVDF for Analytical Probes in Metal Refining and Processing In the demanding environment of metal refining and processing, selecting the right materials for analytical probes is paramount. These probes, operating under harsh conditions, require materials that can endure extreme stress without failure. Polyvinylidene Fluoride (PVDF) excels in this regard, particularly when [...]
Online Total Ammonia Nitrogen Measurement in Wastewater Using the Salicylic Acid method with Novel Fluidics Design Originally published December 2023: Influents Magazine Effluent water quality monitoring is crucial for safeguarding aquatic ecosystems Effective effluent water quality monitoring is crucial for safeguarding aquatic ecosystems and human health. One of the key parameters in assessing water [...]
As Canada takes significant steps to protect its marine ecosystems from the threats of aquatic invasive species, sea shipping companies operating in Canadian waters must adhere to the newly enacted Ballast Water Regulations within the Canada Shipping Act. These regulations aim to minimize the unintentional introduction and spread of harmful organisms through discharged ballast water. [...]
Process Challenges in Extracting Lithium Lithium found in minerals such as spodumene or in brines such as those in salt deserts (aka “salars”) can be difficult to extract. In spodumene, after separation and flotation, further processing of the concentrate may target changing the crystal structure through heat treatment to make it amenable to roasting [...]
Because of its tendency to scale, it is critical to monitor silica concentrations in applications such as semiconductor rinse water and steam power generation. Much of the burden in maintaining silica analyzers relates in some way to the required use of reagents and having to calibrate. As such, recent enhancements have targeted the automation [...]
Lithium is an Important Resource in Reducing Carbon Emissions Lithium's role in Lithium-Ion batteries makes it a key enabler of vehicle electrification and large-scale energy storage making it an important resource in reducing carbon emissions. It is the lightest metal and when used in a battery, the lithium ion moves with relative ease from anode [...]
July 14, 2022 concluded a four-week open house IC Controls held at its facility in Orangeville Ontario. Bringing together people from engineering firms, municipalities, water and wastewater treatment plants, it demonstrated new analyzers from Thermo Scientific Orion and provided a sneak peek at its new digital sensor platform currently in development. Measure in wastewater [...]
In practice, discharge thresholds for Total Residual Chlorine (TRC) in effluent in Canada are becoming more stringent. Although the federal limit of 0.02 mg/ L has been the same for many years, some provinces are introducing measures that require more precision and lower limits of detection. For example, some Environmental Compliance Authorizations (ECA) in [...]
TDS Overview Total Dissolved Solids (TDS) measures the sum of all inorganic and organic substances dissolved in the process. The solids must be small enough to survive filtration through a sieve but not so small that they are ionized or colloidal. They need to stay suspended! TDS sensors measure both soluble compounds such as [...]
Monitoring trace levels of dissolved oxygen (D.O.) accurately using a dissolved oxygen probe can be essential for many industries such as: power generation, semiconductor manufacturing, food and beverage as well as breweries. Dissolved Oxygen removal from any steam and water system is of major importance. Monitoring the D.O. levels to determine the amount of [...]
If your process water has either too low a pH or too high a pH value, it can result in poor quality products or can cause environmental harm. pH and Water Quality Overview If the pH of wastewater is too high or low, it will not be environmentally friendly to release and can harm [...]
Dissolved Oxygen Overview Trace levels of dissolved oxygen can be measured at parts per billion (ppb) or micrograms per litre (µg/L) using a dissolved oxygen meter. Online measurement technology in this concentration range is usually different from that for parts per million (ppm) measurements, One of the problems of dissolved oxygen is that it [...]
The pH sensor is a ubiquitous device in many industries. It measures the concentration of hydrogen ions in water which can help determine the acidity or alkalinity of an environment. The harshness and corrosiveness of environments in which they are placed will alter the lifespan of these sensors. Designed from the outset to survive [...]
The world is becoming more serious about guarding and treating its finite water resources. As part of the larger environmental agenda set by governments, wastewater treatment is an ongoing challenge and where the online ammonia analyzer plays a critical role. The average Canadian may not think about the vast infrastructure, treatment, and analysis needs [...]
