Signs of Corrosion in Water Treatment Systems
Corrosion is a persistent challenge in water treatment, especially in closed-loop systems where water circulates continuously. If left undetected, corrosion can lead to costly damage, reduced system efficiency, and even failures in critical infrastructure. Identifying the signs of corrosion early is essential for preventive maintenance and system longevity.
Common Signs of Corrosion
- Discoloured Water
One of the earliest indicators of corrosion is water discoloration. If you notice a reddish-brown tint, it often signifies iron corrosion, while a blue-green hue suggests copper corrosion. Discoloured water could indicate the deterioration of pipes, tanks, or heat exchangers within the system. - Unusual Metallic Taste or Odour
Corroding pipes can introduce dissolved metals into the water supply, resulting in a metallic taste or an unusual odour. This change can be subtle at first but becomes more pronounced as corrosion progresses. - Visible Rust or Deposits
Rust formation on external components, pipe joints, or valves can indicate that internal corrosion is also occurring. In closed-loop systems, corrosion byproducts can accumulate as deposits, leading to clogged filters and reduced heat exchange efficiency. - Leaks or Pinhole Formation
Over time, corrosion weakens metal surfaces, causing pinhole leaks or even larger breaches. If you observe unexplained water loss or damp areas near piping, corrosion may be the underlying cause. - Reduced System Efficiency
Corrosion can lead to the formation of scale and deposits inside pipes, restricting water flow and reducing system efficiency. This often results in higher energy consumption, decreased heat transfer, and increased operational costs.
How to Detect Corrosion Early
Traditionally, corrosion coupons were used to assess metal loss over time, but they only provide retrospective data. New real-time corrosion monitoring technology allows for early detection within 24 hours. This advanced system not only detects corrosion but also continuously monitors changes in corrosion rates, helping to prevent damage before it becomes a major issue.
By recognising these early warning signs of corrosion and leveraging modern detection methods, you can protect your water treatment system, reduce maintenance costs, and improve overall efficiency.
