Effective biofilm control techniques for clean water systems

25th September 2023

Bacteria in water systems are ubiquitous and diverse. Should a closed system show signs of corrosion and loss of efficiency, biofilm might be the culprit, causing Microbiologically Influenced Corrosion (MIC). Biofilm is traditionally controlled by maintaining relatively low general bacteria (Total Viable Count) levels. These planktonic bacteria levels have no relationship with the presence biofilm, […]

Hidden Costs of Poor Water Quality: Ensuring Reliable, Low-Carbon Heat Delivery

23rd May 2023

Heat networks, or district heating systems, are a relatively new approach to delivering heat to domestic and commercial premises across the UK. Heat is generated from a central source and delivered to multiple locations through networks of pipework carrying hot water. This approach avoids the need for individual heating appliances and offers a quick route […]
