Scale Control in Water Systems

This session explains how scale forms in water systems and the problems it can cause, including reduced heat transfer, increased energy use, and damage to plant. It covers common methods of scale control - primarily conditioners (e.g. the HY-MAG) and softeners, where they are best applied, and key design and operational considerations.

Bacteria and Legionella Control in Domestic Water Distribution Networks

This session compares commonly used methods of bacteria control, with particular focus on Legionella, in domestic water systems within the built environment. It covers a brief history of bacteria and epidemiology, an overview of control methods including temperature, chlorine, chlorine dioxide, ultraviolet light and copper silver ionisation, the merits and limitations of each approach, and key system design considerations.

Understanding Water Filtration

This session compares commonly used filtration methods in water distribution networks. It explains how particulates enter water systems, the problems they can cause, and the role of filtration in protecting systems and users. The talk covers how different filtration methods work, when they should be applied, and how they should be designed into buildings.

Reverse Osmosis

This session provides an introduction to reverse osmosis technology, explaining what it is, how it works, and how it is used to produce high quality water. It covers what reverse osmosis can and cannot remove, key applications, pre-treatment and post-treatment requirements, and how systems are selected.

Water Treatment for Evaporative Coolers

This session provides a practical guide to water treatment for cooling towers, evaporative condensers, and evaporative coolers. It explains the key challenges of scale, corrosion, and bacteria, outlines relevant regulations, and reviews practical treatment approaches. This session is particularly relevant for the design of process water systems in data centres.

Understanding Water Quality

This session explains what water quality means in practice and why it matters for both people and building systems. It covers common water quality parameters, how they are measured, typical problems encountered in buildings, and how water quality influences health, corrosion, scale, bacteria, and system performance.
