The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).
Multiple requests from the same IP address are counted as one view. In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method.
There are three types of treatment methods used for removal of lead from wastewater: (i) Physical, (ii) Chemical, and (iii) Biological treatments (Fig. 10.2). Lead-contaminated wastewater treatment process partitioned into various physical, chemical, and biological treatment methods for Pb removal
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.
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.
The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.
These regulations specify the procedures and provisions applicable during the production, storage, distribution and recycling of lead-acid batteries. The purpose of this article is to …
