Industry Application

Metal & Allied Manufacturing

Steel and aluminium manufacturing, along with surface-finishing operations such as pickling and electroplating, produce highly mineralized wastewater. Typical effluents contain acids, alkalis, oils, cyanides, fluorides, and heavy metals like chromium, nickel, zinc, and iron.

Stream

Metals, oils, phenols, and cyanide

Pickling, electroplating, steel, and aluminium streams can be mineralized, toxic, and hard on conventional plants.

Design priority

Reduce difficult contaminants early

ElectroX helps remove phenols, cyanide, and heavy metals before they constrain reuse or ZLD stages.

Reuse move

Protect downstream membranes

Lower hardness, silica, and reject load can extend membrane life and improve recovery economics.

25,000 litres of wastewater generated per ton of steel produced.

Industry Challenges

High concentrations of phenols, cyanide, and heavy metals

Limited reuse opportunity

High chemical consumption in conventional treatment

High OPEX in ZLD solutions due to low RO/UF recovery

How ElectroX Helps

ElectroX improves removal, uptime, and membrane-stage economics in metal-heavy streams.

Delivers around 90% removal of phenol, cyanide, and heavy metals.

Scalable, modular systems help plants maintain throughput with minimal interruption.

Effective reduction in total hardness and silica extends the life of downstream membranes.

Lower RO reject helps reduce the total operating cost of ZLD systems.
