Battery Acid, the electrolyte in all lead / acid cell batteries, is sulfuric acid (H2SO4) at a concentration of between 15% and 35%.  At this concentration sulfuric acid is very dangerous and will react with almost everything especially organic material including human flesh.

Battery acid must be neutralized before it is disposed of and battery acid, although very dangerous, can be safely neutralized yielding harmless salts. The pH neutralization of sulfuric acid or any concentrated acid is a hazardous task, however, the risks can be controlled.  The heat liberated from the neutralization of sulfuric acid (battery acid) is very high and can result in a temperature rise of over 1000C (2120F). In the lab we have measured temperatures as high as 2500F. 

If extreme care is not exercised the energy released during the neutralization cycle can be explosive and, at a minimum, be sufficient to melt all thermoplastics. Digital Analysis utilizes a unique process for the neutralization of battery acid one in which the rate of reaction is constantly controlled and is limited by temperature. As the temperature of the process rises and begins to approach a field defined setpoint the rate of reaction is slowed or even halted as is dictated by the rate of rise. Additionally, cooling water can be added in the event that the temperature rises beyond a safe level.

Our battery acid neutralizers can be used to neutralize any concentrated acid not just battery acid. Our Waste Acid Neutralization systems are also very well equipped to neutralize almost any concentration of waste acids and bases.

In addition to the neutralization of the sulfuric acid any system handling battery acid must also be concerned with heavy metals including lead (Pb), Zinc (Zn), Copper (Cu) and Nickel (Ni). Heavy metals, being toxic, are very closely regulated and cannot be freely discharged to the environment. All of our battery acid neutralization systems can be equipped with heavy metal removal systems. If metals are of a concern please advise us of this and we can easily configure your system to reduce heavy metals.

Our battery acid neutralization systems are based upon our standard pHASE product line and are rated in gallons per hour (GPH) as opposed to GPM (see chart below).
