Features
Designed to demonstrate Reverse Osmosis process used in distillation of water.
Corrosion resistant components used in the trainer.
Comprehensive Instrumentation Panel with all necessary measuring instruments & Safety Devices.

Tesca Reverse Osmosis Unit is designed to demonstrate water distillation using Reverse Osmosis Technique. The setup consists of a raw water tank fitted with stirring machine. A pump draws salty water from the raw water tank to the spiral wound membrane module. The distilled water & concentrated salt solution are separated & can be collected separately or discharged in to the raw water tank. A distilled water tank is provided for flushing the system. Conductivity sensors are provided to measure the salt concentration at different points. Measuring instruments are provided to measure flow rate & pressure at different locations.
Detailed Operation & Maintenance Manual is provided along with the trainer.
