The impact of liquid alkali concentration on water treatment
Thread Content
Let’s discuss what concentration of liquid caustic soda is used for water treatment by each of us. And if it’s solid caustic soda, what is the concentration of the solution that is prepared? How is dosing controlled?
Liquid caustic is generally 32% in concentration; it is usually diluted by one to two times before being added, so as to ensure a more thorough acid-base reaction and prevent pH distortion.
Caustic soda is generally dissolved to 50%, and then diluted to around 15% before use
It is usually 32%, and when using it, it is diluted with wastewater
