PRO Equipment and Systems: A Complete Buyer's Guide to Pressure Retarded Osmosis Testing Platforms

PRO Equipment and Systems: A Complete Buyer's Guide

Pressure Retarded Osmosis research demands equipment that can recreate and precisely control the conditions under which osmotic energy is generated. Unlike conventional membrane testing, PRO experiments require simultaneous management of hydraulic pressure on the draw side, crossflow velocities on both feed and draw channels, temperature stability, and continuous measurement of water flux, reverse salt flux, and the resulting power density.

Tech Inc., headquartered in Chennai, India, with operations in Vaughan, Ontario, Canada, designs and manufactures Pressure Retarded Osmosis testing equipment specifically for researchers, engineers, and institutions working at the frontier of osmotic energy and salinity gradient power. This guide walks through Tech Inc.'s PRO product line, detailing the engineering behind each system and the considerations that should inform your equipment selection.

Pressure Retarded Osmosis (PRO) Advanced Research System

The flagship Pressure Retarded Osmosis testing system is designed for comprehensive PRO membrane characterization and process optimization. It features a precision-engineered membrane test cell capable of operating at hydraulic pressures up to 80 bar, covering the full spectrum of PRO operating conditions from low-pressure experiments using river water and seawater pairs to high-pressure studies involving concentrated desalination brines.

Key features include variable-speed peristaltic pumps and high-pressure pumps for independent flow control on both channels, real-time monitoring of water flux, reverse salt flux and power density, integrated data acquisition with LabVIEW and SCADA compatibility, and corrosion-resistant construction using SS316L stainless steel, PVDF, and PTFE wetted components.

Pressure Retarded Osmosis (PRO) System

The PRO System is a versatile membrane testing platform optimized for osmotic energy harvesting research. It features precision pressure and flow control, integrated temperature and pressure monitoring, a data acquisition system for real-time performance tracking, and compatibility with both flat-sheet and hollow-fiber PRO membranes.

Complementary Equipment and Membranes

Tech Inc. also manufactures the Lab Scale RO Test Skid with DAQ for groups whose work spans PRO and reverse osmosis. Tech Inc. supplies both flat-sheet and hollow-fiber membrane formats in PVDF, PTFE, and combination configurations for PRO research.

Engineering Specifications That Matter for PRO Research

Tech Inc.'s PRO systems support pressures up to 80 bar, providing substantial headroom for even the most demanding experimental protocols. The flow channels feature carefully controlled channel heights, spacer geometries, and inlet manifolds to promote uniform flow distribution and minimize external concentration polarization. High-accuracy pressure transducers, electromagnetic or Coriolis flow meters, PT100 temperature sensors, and four-electrode conductivity probes ensure measurement uncertainty is sufficiently low to resolve small changes in flux and salt transport.
