Activated Sludge Microbiology Problems and Their Control
A large problem in some plants is a low pH (to as low as pH = 6) caused by extensive nitrification and low wastewater alkalinity. This often causes pin floc and high effluent turbidity. Some plants reduce aeration to reduce nitrification or add soda ash, lime or magnesium hydroxide as a source of alkalinity if this becomes a problem.

Why does Soda Ash cloud up pool water?
Conclusion. Soda ash clouds water because it creates a sudden LSI violation (over +0.30), which forces calcium carbonate to fall out of solution. It happens in two ways simultaneously: the high pH of soda ash converts bicarbonates into carbonates, and soda ash itself is sodium carbonate, which introduces new carbonates.
