Hot Water Ultrafiltration System
Gujarat Ion Exchange and Chemicals Ltd is a leading manufacturer and supplier of Hot Water Ultrafiltration (UF) Systems in India. These systems are specifically designed for industries such as dairy, beverage, pharmaceutical, and food processing, where high-temperature water filtration is essential for hygiene and product quality. These systems are engineered to handle heated water streams while maintaining filtration efficiency.
Our skid-mounted, fully automatic UF units come with PLC-based control, CIP compatibility, and durable SS 316L construction, offering long-term reliability and low maintenance. Whether for product recovery, water recycling, or process water purification, we provide customizable solutions to meet your specific needs.
Working Principle of Hot water uf system
Dual-Stage Filtration
- Surface Screening : Large particulates (>0.1 µm) retained on membrane surface
- Depth Trapping : Smaller colloids captured within the membrane matrix
Crossflow Operation
- 20% concentrate recirculation maintains flow velocity (2–3 m/s) to prevent scaling
- Periodic air-water backpulses (every 15–60 mins) dislodge fouling layers
Preheated Feed Entry
- Hot water enters the UF module through UPVC headers, with temperature monitored via integrated sensors.
Thermal Management
- Automated cooling loop activates if inlet exceeds 45°C
- Steam-in-place (SIP) capability for periodic sanitization at 80°C
