Understanding and Managing Increased TDS from Deionisation Resin

Nicky S

Deionisation (DI) is a widely used water purification method that employs ion-exchange resin to remove impurities. However, one common challenge faced by users of deionisation systems is an unexpected increase in Total Dissolved Solids (TDS) levels. In this blog post, we will explore the reasons behind the increase in TDS from deionization resin and discuss effective strategies to manage and mitigate this issue.

Why Does TDS from Deionization Resin Increase?

  1. Exhausted Resin:

Over time, the ion-exchange resin used in deionisation systems becomes exhausted due to the accumulation of impurities. As the resin reaches its capacity to exchange ions, it becomes less effective in removing contaminants, leading to an increase in TDS levels. This issue typically occurs when the resin bed is not replaced at the appropriate intervals.

  1. Contaminated Source Water:

Another factor that can contribute to the...
