Hot Water Reverse Osmosis (RO) systems
Gujarat Ion Exchange and Chemicals Ltd (GIECL) offers specialized hot water reverse osmosis (RO) systems engineered for high-temperature industrial applications, combining thermal-resistant materials with advanced membrane technology to maintain performance under elevated temperature conditions. The hot water RO system effectively removes dissolved salts, bacteria, and other impurities, delivering high-purity water with consistent quality under high-temperature operating conditions.
A Hot Water Reverse Osmosis (RO) System is a specialized water purification system designed to process feed water at higher temperatures than conventional RO systems. It effectively removes dissolved salts, suspended solids, bacteria, organic contaminants, and other impurities while maintaining high recovery rates and consistent performance under elevated temperature conditions.
Working Principle of Hot water RO system
Thermal Buffering
- Incoming hot water (up to 45°C) passes through heat exchangers to stabilize at 35–40°C
- Temperature sensors trigger cooling loops if feed exceeds membrane limits
Multi-Stage Filtration
- Stage 1: 5 µm sediment filters remove particulates
- Stage 2: Activated carbon absorbs chlorine/organics
- Stage 3: High-pressure pumps (3–4 bar) push water through TFC membranes
Selective Separation
- Membranes reject 97–99% of dissolved salts, heavy metals, and microbes
- Concentrate stream (20–30%) gets diverted for thermal recovery
Post-Treatment
- UV sterilization ensures microbial safety
- Remineralization cartridges adjust pH for corrosion control.
