Our company has to discharge 5-6 tons of acidic wastewater per day; it is neutralized using calcium hydroxide, and as a result the originally colorless water turns black. Is there any way to prevent it from changing color?

The originally colorless water turned black; what substance caused it to change color?

What kind of wastewater is it mainly? Determine the components of the wastewater; the black substance formed as a result of chemical reactions – as mentioned on the first floor, it is necessary to identify the coloring agents before any other treatment methods can be applied
