Brine Management

Brine — the concentrated reject stream from desalination — is a growing environmental challenge in the GCC. The Arabian Gulf receives the largest concentration of desalination brine globally, and new projects face tightening discharge standards. Brine management technologies ranging from enhanced dilution diffusers through to zero liquid discharge (ZLD) crystallisation are required for regulatory compliance. We supply brine treatment and disposal equipment.

What we supply

• Multi-stage flash concentrators for brine pre-concentration
• Membrane brine concentrators (high-pressure RO) for ZLD pre-treatment
• Evaporation ponds with liner systems for inland brine disposal
• Brine crystallisers — forced circulation and draft tube for salt recovery
• Spray evaporators and mechanical vapour recompression (MVR) systems
• Brine dilution and diffuser systems for coastal outfall compliance
• Salt recovery and handling equipment for crystalliser output

How the project proceeds

1. Assess the brine volume, TDS, and disposal or discharge option
2. Select brine management technology based on regulatory requirement and economics
3. Source equipment from qualified manufacturers; manage delivery and quality documentation
4. Support commissioning and regulatory compliance demonstration

Why Infinity

Brine management is increasingly a regulatory constraint, not just a technical one. We source equipment with performance guarantees referenced to the regulatory limit — not just nominal capacity — so the client has documentation to support their environmental permit.
