Keep it fresh! W
e live in a water-hungry world. Globally, around four trillion cubic meters of freshwater are used
per year for a wide variety of purposes, from potable water through to energy production and use in industrial and agricultural applications. As the need to manage the world’s precious water supplies more sustainably becomes more pressing, it is becoming ever more important for water utilities to be able to keep a track on this water as it makes it way from the treatment plant to the point of
use and then back into the environment, both in terms of quantity and quality. When it comes to water quality in particular,
water utilities engaged in potable and wastewater treatment are expected to meet increasingly high standards for the supply and treatment of water, both to meet public expectations and to satisfy the requirements of ever more stringent environmental legislation. The same applies to major industrial users of
water, who must keep a close eye on both the quality and quantity of the water they are discharging in order to minimise the impact of their operations on surrounding watercourses.

Why analytical thinking has never been more important when it comes to water quality
As concerns grow about the ability of the world’s existing freshwater supplies to meet the demands of a steadily rising global population, there is a pressing need to ensure that water is treated to the highest standards to ensure that it can continue to meet the needs of as many people as possible. Jonathan Penn, product line manager – Water Analysis for ABB’s Measurement & Analytical business explains how the latest water quality analysis technology can help achieve this
or encyclopaedia, which may have been out of date, whereas it is now possible to access a wealth of up-to-the-minute information through a smartphone. Like an out-of-date encyclopaedia, the
drawbacks of traditional manual-based extractive sampling in water quality analysis make it inherently unsuitable for a world demanding quick answers. The delays and uncertainties associated with manual sample collection, plus the fact that a sample could only ever be indicative of a particular moment in time, has steered users towards online analysers looking to satisfy expanding operational and legislative requirements. Upgrading analytical infrastructure can be a
significant undertaking, but digitalising operations does not have to be complicated. Smart instruments can be implemented alongside their analogue counterparts to allow upgrades to be made as required. Once we scratch the surface of the convenience of accurate continuous analysis over manual sampling, there are many cost saving and
