Brine Concentration

Brine concentration refers to the process of concentrating high Total Dissolved Solids (TDS) wastewater streams, typically generated from processes like ion exchange regeneration, textile dyeing, RO reject, and industrial chemical manufacturing. These streams contain a mix of sodium chloride, calcium, magnesium, sulfates, and other salts, making their treatment challenging. At SEDL, we offer advanced evaporator systems that concentrate brine efficiently and prepare it for further crystallization or safe disposal.

Challenges in Brine Concentration

Handling and concentrating brine comes with multiple technical challenges

High TDS & Scaling

The presence of salts like CaSO₄, MgCl₂, and silica leads to rapid scaling inside heat exchangers and evaporators.

Corrosive Environment

Chloride-rich brines are highly corrosive, requiring special metallurgy and material selection.

High BPE (Boiling Point Elevation)

Salt-rich solutions elevate the boiling point, increasing energy consumption.

Crystallization Risk

Uncontrolled concentration can lead to salt crystallization and equipment choking.

Disposal Issues

Concentrated brine needs further handling like crystallizers or solar evaporation for zero discharge.

Our Solution

SEDL offers a robust brine concentration system that is engineered for reliability and efficiency

Anti-Scaling Design

Optimized flow patterns and online cleaning (CIP) system reduce fouling and downtime.

Special Metallurgy

Use of duplex SS, titanium, or FRP-lined carbon steel to resist chloride-induced corrosion.

Vacuum Operation

Low-temperature evaporation under vacuum helps reduce scaling and improves efficiency.

MVR Technology

Mechanical Vapor Recompression integration for low energy consumption and minimal steam usage.

Crystallizer Integration

Optionally paired with Forced Circulation Crystallizers (FCC) or ATFD for complete ZLD compliance.
