Metals and Metallurgy
Metals and Metallurgy
The Metals and Metallurgy Industry generates large volumes of complex wastewater containing heavy metals, oils, acids, alkalis, suspended solids, and toxic contaminants. Strict environmental regulations and water scarcity demand advanced, reliable, and sustainable treatment solutions.
Purlieusinc delivers end-to-end water and wastewater treatment systems designed specifically for metal processing units, foundries, rolling mills, forging plants, smelters, galvanizing units, and alloy manufacturing industries.
We help metal industries achieve regulatory compliance, water reuse, and zero liquid discharge (ZLD) with high-performance treatment technologies.
Effluent Treatment Plant (ETP) for Metals & Metallurgy Industry
Metal and metallurgy effluents often contain chromium, nickel, zinc, copper, iron, cyanides, oils, and high TDS.
Purlieusinc’s ETP Plants are engineered to effectively treat these pollutants through physical, chemical, and biological processes.
Key Benefits:
Efficient removal of heavy metals and toxic contaminants
Compliance with CPCB, SPCB, and global discharge norms
