Reverse Osmosis (RO) membranes are crucial in water purification systems, ensuring the production of high-purity water essential across various industries. However, these membranes are prone to erosion, a form of degradation that can significantly impair their performance and shorten their lifespan. Causes of Membrane Erosion Erosion in RO membranes can stem from several factors: 1. … Read more
Effluent treatment plants (ETPs) are essential for treating wastewater before it is discharged into the environment, ensuring compliance with regulatory standards and protecting ecosystems. However, these plants can encounter operational issues that compromise efficiency and effectiveness. Membrane autopsy, a comprehensive diagnostic tool, is crucial in troubleshooting and resolving failures in ETPs. This article explores the … Read more
Membrane systems, such as those used in Reverse Osmosis (RO), Ultrafiltration (UF), and Membrane Bioreactors (MBR), are integral to water purification and treatment processes. However, these systems are susceptible to fouling and scaling, which can significantly impact performance. Panic cleaning—emergency cleaning due to sudden performance drops—can lead to harsh practices that degrade membrane life. Understanding … Read more
Reverse Osmosis (RO) systems are essential for producing high-purity water, crucial in various industries from pharmaceuticals to drinking water treatment. However, the performance of these systems can be compromised over time due to membrane fouling, scaling, and other issues. Enter the art of RO membrane autopsy—a powerful tool for diagnosing and resolving these problems, ultimately … Read more
Physical damages in membrane is a common phenomenon. The physical damage could be such as increasing salt passage, change in flux and so on. With the good experience and our study in membrane autopsy, we found physical damage and irreversible damage to the membrane caused by the crystallized minerals majorly silica where colloidal silica plays … Read more
Antiscalant’s dynamic efficacy testing is an emerging testing which help customers to understand the exact performance of their anti-scalent product and thereby take necessary actions to improve formulations if necessary.Fortunately, at VIPANAN, due to our vast industrial experience, has developed a specialization in performing Antiscalant’s efficacy testing.With new perspective, introduced by VIPANAN, Testing of antiscalant helps … Read more
Extensive studies of membrane autopsies shows the physical damage of membrane such as increasing salt passage, change in flux and so on . After studying innumerable membranes we found silica plays vital role in most of the physical and irreversible damage of the membrane among the crystallized minerals. In such cases, the foulant composition contain … Read more
Using Raw water in industry is an advantage, however it has its own challenges and difficulties too. Treating raw water is a complex process, though it seems to be a simple process prima-facie. If, due consideration to seasonal deviation in water quality, understanding and foreseen the errors in pre-treatment system, if not given, then membrane … Read more
Membrane autopsy is defined as, ‘Excellent tool or technique to understand and diagnose the problem related to fouling, scaling, salt passage flow, flux and pressure difference across the sides.’ However, with our vast experience in such autopsies we understood that Autopsy technique has it’s meaning, way beyond the above-mentioned definition. It is actually a silent … Read more
CETP (common Effluent Treatment Plant) located in one of the well known textile industry zone, has RO Membrane system for treated water recycling. In, comparatively, shorter span of two years, management has to replace all the membranes forcefully due to deterioration of product quality, quantity and rise in unscheduled cleaning frequency. Deterioration of product quantity … Read more
