ChemicalNeutralization

To protect neighboring water systems, industrial wastewater must be neutralized so that it is neither acidic nor alkaline prior to its discharge. The neutralization process takes place in a tank where aqueous solutions of an acid and a base are added to wastewater. Sulfuric acid, sodium hydroxide and calcium carbonate are most commonly used.
Challenge
Level is measured in the neutralization and chemical regeneration tanks which typically involve agitation and aggressive chemicals. Ideally, the tank level monitoring system should be easily removable for frequent cleaning. Contact level sensors should be single rod types to avoid media buildup.
