The Evolution of High Recovery Reverse Osmosis to Achieve 95%+ Recovery
Increasing regulatory requirements and disposal costs around the world, as well as ESG mandates and incentives for recycling, are prompting industries to reduce their water and energy footprint, and highlight a growing need for innovation in reverse osmosis (RO) technology. Historically, it was challenging for conventional RO technologies to achieve recovery rates greater than 75% […]
Designing with Turbochargers: Case Studies for Ultra High Pressure RO Operation
The current ~1,200 psi environment for membrane desalination and concentration was established at the turn of the millennium. At that time, system recovery was limited by the operating range of RO membranes, which could handle a maximum brine TDS of ~90,000 ppm. However, demand for higher RO pressures to address feed salinity and concentration requirements […]

Key Parameters to Consider When Designing a Membrane Plant
The Art and Science of Cleaning RO and NF Systems
Clean in Place (CIP, cleaning) is an integral part of maintaining reverse osmosis (RO) and nanofiltration (NF) systems. Over time, organic and inorganic foulants present in the feed water will build up on the membranes surface. These foulants reduce the systems efficiency and can lead to mechanical damage of the membrane surface. Normalizing operating data […]
Artificial Intelligence for Optimizing Reverse Osmosis Operations, Saving energy and Chemicals
Tap Into Your Data To Improve Membrane Cleaning, What is AI and How Can It Support Operators
Nowadays, numerous sensors are installed at membrane facilities that collect a considerable amount of data each hour. Analyzing these data brings tremendous opportunity for the operators to better operate the system for tasks such as membrane cleaning or optimize chemical dosing. Currently, many facilities still perform manual data collection and review maintenance logs infrequently. These […]
Potential Cleaning Issues and Membrane Residuals Handling
As climate change further stresses water supplies, there’s increased focus on minimizing waste from municipal WTP’s. As a result, facilities often investigate ways to either reduce waste or recycle waste streams, and optimize cleaning regimes (frequency, chemicals…). The first portion of the presentation will cover items to check if cleaning recovery isn’t as expected. It’s […]
