Turbidity Testing Explained.

 

A turbidity test for your boiler is important because high turbidity indicates the presence of suspended particles like rust and sediment that can cause corrosion, scale buildup, overheating, and blockages in the boiler and heating system. This ultimately leads to decreased efficiency, increased fuel costs, component damage, and a shortened boiler lifespan.

Why Turbidity is a Concern

 

The test helps determine the water quality and the need for treatments like chemical inhibitors, power flushing, or filters to maintain optimal system performance and prevent costly breakdowns. 

  • The suspended particles that cause turbidity can be impurities like rust and magnetite. These particles contribute to the corrosion of boiler components and can form insulating scale on heat exchanger surfaces. 

 

  • Scale acts as an insulator, making the boiler less efficient at transferring heat. This forces the system to use more fuel to reach the desired temperature.

  • Sediment and scale buildup can restrict water flow, leading to overheating and eventual failure of boiler components. 

  • Scale acts as an insulator, making the boiler less efficient at transferring heat. This forces the system to use more fuel to reach the desired temperature. 

  • Sediment and scale buildup can restrict water flow, leading to overheating and eventual failure of boiler components. 

  • The suspended solids can accumulate in pipes and radiators, causing blockages and uneven heating, seriously reducing the life expectancy of your boiler.

How Turbidity Testing Helps

A turbidity test measures the cloudiness of the water, indicating the level of suspended solids present in the system.

The test results help determine if treatment is needed to protect the boiler.

  • Clear water with documented inhibition may mean no action is needed.

  • Slightly blurred water may suggest adding chemical inhibitors, and potentially, a filter may be beneficial.

  • Completely black water indicates significant sludge and debris, necessitating a full flush with cleaner, and the addition of inhibitors is required. 

  • By identifying water quality issues early, you can take action to prevent major problems and extend the life of your boiler significantly.
