UV254 water monitoring: tracking organic matter UV254 is one of the parameters used in water quality analysis. The measurement tracks the absorption of ultraviolet light at 254 nanometres (nm) by dissolved organic compounds that absorb at this wavelength. It provides a continuous reading of their variations, without the addition of reagents or consumables. This measurement…
Ammonium analysis in water: which method should you choose? Ammonium (NH₄⁺) is a form of nitrogen found in many aquatic environments. Its analysis consists of measuring its concentration in water in order to monitor changes in an environment, control certain treatments or detect changes in water quality depending on the context. In wastewater, drinking water,…
Redox potential measurement in water: understanding and monitoring ORP Redox potential measurement in water, also known as oxidation-reduction potential or ORP, assesses the balance between oxidized and reduced forms of the compounds present in an aqueous medium. Expressed in millivolts (mV), it provides information on the oxidizing or reducing state of the water. For operators,…
Total suspended solids (TSS): an indicator for your industrial discharges In discharge management, the concentration of total suspended solids (TSS) provides direct information about the amount of solid particles present in an effluent. It affects discharge quality, the operation of treatment facilities and regulatory compliance. In the field, an increase in TSS often results in…
Sulfite Analysis: Corrosion Control and Process Monitoring Sulfite analysis is a key element in monitoring installations that use treated water, particularly in thermal circuits and certain industrial processes. Sulfites, present as SO₃²⁻ ions (sulfite ions), are commonly used to scavenge residual dissolved oxygen and mitigate oxygen-induced pitting. Their concentration must be precisely controlled to ensure…
Measuring Chemical Oxygen Demand (COD) in water Water quality depends on the ability to identify and quantify pollutants likely to affect natural environments, industrial processes, or resources intended for human consumption. Among the indicators used, measuring Chemical Oxygen Demand (COD) plays a central role in assessing the overall load of oxidizable substances present in water.…
Wastewater Conductivity Measurement: Role and Interpretation Measuring conductivity is a widely used field parameter for monitoring changes in wastewater and detecting anomalies quickly. This article explains how conductivity works, its role in urban and industrial sanitation, and the different methods that ensure reliable and continuous monitoring. Understanding wastewater conductivity is essential for anticipating unusual discharges,…
Measuring dissolved oxygen (DO) in water is a fundamental parameter for assessing balance in natural environments and ensuring the proper operation of treatment systems. Whether in aeration basins, industrial waters, or aquatic ecosystems, monitoring this parameter provides key insight into biological activity, process performance, and environmental compliance.
Water quality is one of the essential levers for the success of aquaculture. Even minor variations in certain parameters can have significant impacts, while precise monitoring ensures a favorable environment for fish development.
Turbidity is a critical parameter in water quality assessment. It refers to the cloudy appearance of water caused by suspended particles such as sediments, organic matter, or certain pollutants that can compromise quality. Monitoring turbidity is therefore essential to ensure compliance with regulatory standards and to optimize treatment processes, whether for drinking water, wastewater, or industrial effluents.
In this article, we’ll explore the challenges linked to turbidity, regulatory requirements, and the methods used to measure it effectively.
