Brine Recovery

Recovery Technology

The Brine Recovery System is an advanced industrial solution designed to recover and reuse caustic brine from sugar refinery processes. By integrating membrane filtration and ion exchange technologies, the system significantly reduces effluent discharge while improving operational efficiency and sustainability.

This system ensures optimal resource utilization by recovering valuable chemicals and minimizing environmental impact, making it an essential component for modern sugar, ethanol, and chemical processing industries.

System Overview

In sugar refineries, ion exchange resins are widely used for decolorization of sugar syrup. During regeneration, large volumes of colored spent caustic brine are generated, which traditionally require disposal and treatment.

The Brine Recovery System eliminates this challenge by recovering reusable brine through advanced membrane separation. This reduces chemical consumption, lowers operational costs, and ensures compliance with environmental norms.

Process Flow & Operation

• Collection of spent brine in storage tanks
• Pre-filtration using bag filters and sand filters
• Fine filtration through cartridge filters
• High-pressure pumping into membrane modules
• Separation into permeate (clean brine) and retentate
• Recycling of permeate back into the system
• Disposal or treatment of concentrated reject
• Automatic cleaning using CIP system

Technical Specifications

Key Advantages

• Eliminates need for acid neutralization
• Significant reduction in chemical consumption
• Lower effluent treatment cost
• High recovery efficiency up to 95%
• Improved plant sustainability
• Fully automated and easy to operate
• Compact and modular system design

Working Principle

The system operates on membrane separation technology, where high-pressure pumps force the brine solution through specialized membranes. These membranes allow clean brine to pass while rejecting impurities, color compounds, and dissolved solids.

The recovered permeate is reused in the process, while the retentate is either treated further or safely discharged, ensuring minimal environmental impact.
