What Is Ultrafiltration? Ultrafiltration, or UF, is a membrane process that filters water by physical size. It sits between microfiltration and nanofiltration on the filtration scale, and it has become the standard way to produce clean, low-turbidity water, both on its own and as the step that protects RO membranes downstream. Here is what it is and where it fits. UF fundamentals UF pushes wate...

Best Antiscalants for RO Systems Scaling is one of the fastest ways to lose recovery and flux in an RO plant, and an antiscalant is the cheapest insurance against it. The catch is that "best" depends on what your feed water is trying to precipitate. A product that handles carbonate beautifully may do little for silica. Here is how to match the antiscalant to the scale. What antiscalants do An a...

RO Membrane Cleaning Guide An RO system that has lost output is almost always fouled, and cleaning-in-place (CIP) is the fix. Get it right and flux and rejection come back and the membranes run longer. Get it wrong and you either burn through chemicals or damage the elements. Here is how to do it properly. When to clean Judge it on normalised figures rather than the raw gauges, because a change...

Water scarcity is becoming one of the defining industrial and environmental challenges of the 21st century. Population growth, industrial expansion, climate change, groundwater contamination, and prolonged droughts are putting enormous pressure on freshwater supplies worldwide. As demand for clean water rises, desalination has become one of the most important technologies for securing sustainable...

How Membranes Produce Clean Water    Reverse osmosis has emerged as the backbone of water purification processes around the world. From the water you use from the tap to drink in coastal towns, to the highly purified water used in various factories, the water that people consume today has been filtered through a membrane process. It is highly efficient, easily scalable and works ...
