Many industrial wastes contain acidic or alkaline materia ls that require neutralization prior to discharge to receiving waters or prior to chemical or biological treatment. (Eckenfelder, 2000) Neutralization is the process of adjusting the pH of water through the addition of an acid or a base, depending on the target pH and process requirements.

Neutralizers contain media that interacts with the condensate to lower its acidity, or raise its alkalinity. The steps that happen during neutralization are: Acidic condensate leaves the high-efficiency appliance and slowly enters the neutralizer. Condensate makes contact with the media and “soak time” begins.

Thus, alkaline water will neutralize this acid that our body will release. It is recommended to consume foods which are 70% alkaline and 30% acidic and once you consume it, the pH level of the body will now be neutral. Consuming alkaline water is best if you do consume food that does not balance your pH level of the body.

wastewater is acceptable for discharge. Corrosive wastewater can be neutralized. Catch the wastewater, measure the pH, and add sufficient neutralizing agent to bring the pH to an acceptable level. To neutralize acidic waste water, add an alkaline neutralizing agent. To neutralize alkaline or caustic wastewater, add an acidic neutralizing agent. 3. Wastewater that CANNOT be neutralized on site.

The simplest option for acidic, alkaline and biodegradable cleaners is allowing rinse water to soak into soil. This may require soil amendments to adjust pH and is not appropriate for solvents with toxicity or biodegradability
