The waste alkali liquor generated during hot-dip galvanizing typically contains oil contamination, dirt, and scum. The general treatment method involves pumping out the waste alkali liquor and filtering it to separate the oil, water, and scum. The alkali liquor obtained at this stage is generally used to neutralize waste acid liquor.
The flux waste liquor (ammonium chloride solution) generated during hot-dip galvanizing is usually used to neutralize waste acid liquor.
