Below 10G, it mainly depends on your chlorine production. Only if you use a chlorine tower during emergency shutdown or gate failure, it also depends on the size of your alkali tank. Can you neutralize it once or twice before taking a sample to analyze the concentration?
1Alkali concentration is controlled at 11.5%.

The concentration of 12%-13% hyposodium alkali is 19%~22%. The original poster cannot discharge it directly. How good is recycling. Generally, it is best to control the alkali concentration at 0.1~1%. I don’t know if this answer is satisfactory.
