How to dispose of waste alkaline solution?
Thread Content
How to dispose of spent alkaline solution (about 10%)? It contains some salts such as sodium formate; please give some advice.
After neutralization, the solid phase is recovered while the liquid phase is sent to the wastewater treatment system
Personally, discharging alkaline slag waste liquid directly into wastewater can easily kill the bacteria in that wastewater. .
Add some calcium carbonate to produce calcium formate, a feed additive.
It can be used for alkali liquid desulfurization in boiler desulfurization systems.
The WAO (Wet Oxidation Separation) unit can function regardless of the oil content; as a last resort, a waste alkali incinerator can be used
Headaches are such a problem! We are also facing this problem!

We are faced with the problem of how to deal with waste acid water; currently, lime is used for neutralization, but this approach is not conducive to cost control and does not align with the principles of a \"circular economy\". “\"Treating waste with waste\" or \"waste utilization\" is probably the best approach. It is hoped that discerning policymakers will locate enterprises that generate alkaline wastewater and those that generate acidic wastewater in the same industrial park!
