Avoid Critical pH Drops in Your Aeration Process

14 May 2019


Have you ever experienced significant drops in pH at your WWTP?

While most plants will run with stable pH for long periods of time, problems in the nitrification process or seasonal changes in the water matrix can lead to lower alkalinity levels in the water.
Low alkalinity levels can lead to bigger problems. When alkalinity is low, your water matrix loses its capacity to buffer for pH change during the nitrification process. When pH levels drop, your process may show loss of performance in nitrification (sometimes permanently damaging the bacteria population), and risk of permit violations for ammonia and pH.

Sites that do not continuously monitor their alkalinity levels trust that continuous fixed dosing of lime, or other alkalinity supplementation is the solution to remaining in compliance. This often leads to under or over-dosing, compromising either costs or plant performance.

There are better alternatives.

The new Hach® EZ Series Hardness/Alkalinity Analyser allows you to continuously monitor your alkalinity levels and adapt your dosing timely and accurately. This can ensure good alkalinity levels, a stable nitrification process, and guarantee your permit adherence.
