Are conventional effluent purification processes used for the recovery of lead acid batteries?

The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the advanced processes already being implemented by some environmental managers.

How much lead is in wastewater?

The presence of lead in the wastewater from the lead-acid battery industries can range from 3 to 9 mg/L. Every day, they release 120,000 L of this wastewater. The permissible limit by WHO in drinking water is only 0.01 mg/L.

Can We valorize battery manufacturing wastewater characterized by high salt concentrations?

In this study, we demonstrate a practical approach for valorizing battery manufacturing wastewater, characterized by high salt concentrations. This approach overcomes the osmotic pressure limitation while ensuring high overall yield and purity.

How do lead-acid batteries reduce environmental impact?

It is evident that the segregation and independent treatment of the most polluting effluents from dismantling and washing lead-acid batteries means that much of the rest of the effluents can be discharged; this therefore simplifies their treatment and minimises the environmental impact.

Are lead batteries toxic?

Every year thousands of lead batteries are used and discarded when reaching the end of their useful life, especially in the automobile industry. Some of the materials they are compose of have high polluting potential; especially Pb, Cd and other highly toxic heavy metals, as well as the risk posed by their high H2SO4 concentration.
