Effluent Treatment Plant - Batch And Continuous Operating Units For Lead Recycling | Efficient Ph Balancing, Flocculation, And Sludge Dewatering Process

Effluents from such used batteries mainly consist of sulphates and sulphides of lead, small quantity of lead and diluted sulphuric acid. Further effluent from container washing which mainly contains small quantity of lead is also fed to the ETP. This effluent has low pH values. pH balancing agent (caustic or lime in this case) is added to adjust the pH and also for
Coagulation. The effluent is then mixed for Flocculation. The flocks so formed are settled and dewatered on a Sludge Bed (or through Filter Press). Treated effluent after this is further polished using filters. While treated water may be disposed or used as permitted by law, sludge is recharged into furnaces for recycling and reclamation of lead*.
An Effluent Treatment Plant for lead recycling units can be designed as a Batch Type unit or as a Continuous Unit. This mainly depends on the quantity of effluent to be handled. While smaller quantities can be treated in batches, quantities above 10 kl/day are to be treated in Continuous Operating Units.
