Reverse Osmosis Pilot Plant – HydraNexis- HNX 05
A CE-certified precision laboratory apparatus for engineering experimentation and technical education, manufactured by Scientico India to ISO 9001:2015 standards. Supplied with calibration certificate, operation manual, and complete export documentation. Designed for Water Treatment Technology laboratories in engineering colleges and technical institutions.
The Reverse Osmosis Pilot Plant (HydraNexis HNX 05) is a laboratory and pilot-scale water purification system designed to demonstrate membrane-based desalination using reverse osmosis. Manufactured by SCIENTICO under the HydraNexis series, this unit is intended for engineering colleges, environmental laboratories, and research institutions. It enables systematic study of pressure-driven membrane separation and water purification technology.
Product Overview
The HydraNexis HNX 05 operates on the principle of reverse osmosis, where a solvent is forced through a semi-permeable membrane by applying hydrostatic pressure greater than the osmotic pressure. This causes water to pass through the membrane while dissolved salts are retained.
A sodium chloride solution of controlled concentration, prepared in a stirred raw water tank (up to 4 percent maximum), is pumped into a spiral wound polyamide membrane module. The applied pressure drives water through the membrane as permeate, while the concentrated solution exits the module as retentate and is returned to the feed tank. The permeate is collected separately for analysis. Conductivity measurements of the feed, permeate, and retentate streams are used to assess separation efficiency. A separate distilled water tank is provided for membrane flushing, and optional UV treatment can be used for permeate sterilization.
