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.
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.
