A process of treating industrial waste water contaminated with environmentally unacceptable amounts of sulfuric acid and heavy metals such as lead, copper or zinc is disclosed which permits lowering of the concentration of the contaminants to a level permitting discharge to the sewer. Waste water resulting from floor wash and spray washing of lead acid batteries prior to …
EPA promulgated the Battery Manufacturing Effluent Guidelines and Standards ( 40 CFR Part 461) in 1984 and amended the regulation in 1986. The regulation covers dischargers.
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.
For additional information regarding Battery Manufacturing Effluent Guidelines, please contact Erica Mason ([email protected]) or 202-566-2502.
Regulated pollutants (varying by subcategory) include cadmium, chromium, cobalt, copper, cyanide, iron, lead, manganese, mercury, nickel, oil & grease, silver and zinc. Note: the NAICS listing is provided as a guide and does not define the coverage of the Battery Manufacturing category.
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.
Water is used in battery manufacturing plants in preparing reactive materials and electrolytes, in depositing reactive materials on supporting electrode structures, in charging electrodes and removing impurities, and in washing finished cells, production equipment and manufacturing areas.

In general, process wastewater discharges result from the preparation and application of electrode active materials (steps 1-6 above), formation and charging (step 7), washing finished batteries (step 10 above), and from the various ancillary op- erations (floor and truck washing, laboratory testing, and per- sonal hygiene activities).

At present, China''s battery industry implements the "Comprehensive Wastewater Discharge Standards" (GB8978-1996) and "Comprehensive Air Pollutant Discharge Standards" (GB16297-1996), with low entry barriers and weak targeting. It is necessary to develop and implement stricter emission standards to increase the industry''s environmental entry barriers. Therefore, …
Heavy metals removal from water up to acceptable levels for discharge or reuse is one of STC''s specialties. The STC plants are applicable in the field of battery manufacturing, battery recycling, secondary lead production as well as in mining operations and meet the most severe regulations for heavy metals content in the discharged water.
Indian policy makers often fail to appreciate the difference between discharge and reuse standards. Discharge standards primarily work on the premise of dilution of treated water with fresh water to achieve the desired water quality. On the other hand, when wastewater is treated for reuse, it does not have the benefit of dilution and hence ...
Coolant drainage: The process of cooling the electric vehicle battery cells during charge and discharge cycles generates wastewater. Solvent evaporation: Organic solvents are used during the manufacturing process of EV batteries. These solvents can evaporate and be released into the water as wastewater.

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 H 2 SO 4 concentration.
The Battery Manufacturing Effluent Guidelines and Standards are incorporated into NPDES permits for direct dischargers, and permits or other control mechanisms for indirect dischargers (see Pretreatment Program).
