What impact will the addition of ammonia to circulating water have on water quality?
The pH of the circulating water rises, NH3-N levels increase, algae proliferation intensifies, and the effectiveness of bactericides **decreases**
We have encountered such a situation here: the staff working with the circulating water could smell ammonia in the circulation tank, and upon analyzing the pH level, it was found to be very high
An increase in pH leads to an increase in algae in the system, and in severe cases it can cause scaling in the system.
1. The pH first rises and then falls； 2. No residual chlorine detected in chlorination monitoring ； 3. Microbial reproduction increases, causing the water quality to become turbid. 4. The corrosion rate of copper materials increases rapidly, with an increase in copper ions in the water. 5. The total iron level rises rapidly.
Local ammonia leakage can, over time, cause the pH of the circulating water to rise, leading to increased microbial growth and water turbidity. This facilitates corrosion of the circulating water equipment used throughout the plant, resulting in an increase in metal ions in the water. Such conditions cause scaling in heat exchangers, reduce their efficiency, increase energy consumption, and thus raise costs.
1. It causes scaling and blockage in the heat exchanger, resulting in poor heat exchange efficiency； 2. An important factor is what causes corrosion in copper-core valves.
The direct effects are an increase in pH value and NH3-N, which over time can exacerbate corrosion and scaling in heat exchangers and pipelines!
