Battery Acid, the chemical electrolyte in all lead / acid cell batteries, is sulfuric acid (H2SO4)at a concentration of between 15 and 33% At this concentration sulfuric acid is very dangerous and will react with almost everything such as 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 heat liberated from the neutralization of sulfuric 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 process 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 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 temperature rise. Additionally quench 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. These 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 the lead (Pb) content. Lead, being highly toxic, is 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, specifically lead (Pb) reduction systems. If Pb is a concern please advise us of this and we can easily configure your system to reduce lead or any other heavy metal.

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