Correct pH balance is a key factor in many processes. pH plays a significant role in everyday life from blood composition in the human body, to plant growth, to the application of paint. Many water treatment processes like chlorination, chloramine formation, and floc formation during coagulation are heavily dependent on water pH.
Moreover, pH influences corrosion and the efficiency of iron and manganese removal.
pH correction must be the first step in any water treatment sequence because it will influence further chemical reactions. We can help verify pH levels in raw and treated water.
The Avalon Institute's water quality assessment services can determine the type and quantity of pH correction agents required.
pH correction agents are available through the Osorno Store in 1 litre bottles, 20 litre delcans or 208 litre drums.
Sodium hydroxide and sodium carbonate (soda ash) are effective pH correctors. However, we only recommend using soda ash to increase water alkalinity.
Some uses of sodium hydroxide include:
We suggest using sodium hydroxide instead of soda ash when you want to increase pH. Sodium hydroxide is twice as effective at increasing pH than soda ash. For a given pH correction, the sodium content will increase only by half, which is more important for people concerned with sodium in food and water.
We recommend using hydrochloric acid to decrease pH for swimming pools and water treatment plants.
For swimming pools:
For water treatment plants:
