ROPRO

ROPRO, a software program developed by KOCH Membrane Systems, Inc., is a notable tool in the Education category, specifically under Science Tools. The latest version, 8.06, serves as an invaluable resource for estimating the performance of spiral wound RO membrane elements. Available for free under a Freeware license, ROPRO can be downloaded and operates seamlessly on a range of Windows XP, Vista, 7, 8, 10, and 11 systems.

ROPRO is designed to predict the impact of different system process design choices, including single pass, single pass with recycle, two-pass with or without interstage pumping, and two-stage concentrator configurations. Users can explore a variety of performance scenarios thanks to an up-to-date performance database which includes high surface area, high rejection seawater elements, and the MegaMagnum large diameter spiral elements.

The software also allows for the modification of several key variables within an array: element type and age, manifold pressure loss, and permeate back pressure. It also supports interbank boost pumps, calculating pumping power requirements for both feed and interbank pumps, providing permeate degassification, chemical addition for pre- and post-treatment, and enabling multiple feed, bypass, and product stream blending.

Pros:

• Comprehensive tool for estimating the performance of RO membrane systems.
• Incorporates a fully up-to-date database of membrane elements.
• Flexible in allowing modifications to pivotal variables.
• Free download available, making it accessible at no cost.
