The conventional treatment of these effluents consists of the following main stages:. Adjusting the pH to approximately 9, usually either with NaOH or Ca(OH) 2.Although NaOH is more expensive, it is also cleaner and more effective as it is a strong base, while Ca(OH) 2 is dirtier although cheaper. Its advantage is that the hydroxides formed are denser and easier to decant.
Real-time aging diagnostic tools were developed for lead-acid batteries using cell voltage and pressure sensing. Different aging mechanisms dominated the capacity loss in different cells within a dead 12 V VRLA battery. Sulfation was the predominant aging mechanism in the weakest cell but water loss reduced the capacity of several other cells. A controlled …
