Membrane autopsy is defined as ‘an 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 the Autopsy technique has its meaning, way beyond the above-mentioned definition. It is actually … Read more
A Large Automotive manufacturer in India was operating a traditional ETP (Effluent Treatment Plant) with UF (Ultra Filtration) and RO (Reverse Osmosis) for treated water recycling for 5 years. Last year, they modified their effluent treatment plant and adopted MBR (Membrane Bioreactors) based treatment. Naturally, being the latest trend, they were expecting better performance and … Read more
In water treatment systems, antiscalants play a critical role in preventing the formation of scale, which can lead to significant operational issues and increased maintenance costs. However, ensuring that these chemicals perform effectively over the long term requires thorough and ongoing testing. Scale buildup, which consists of minerals such as calcium and magnesium, can lead … Read more
Antiscalants play a crucial role in water treatment systems, particularly in preventing scale formation on equipment like reverse osmosis (RO) membranes and heat exchangers. By inhibiting mineral crystallization and deposition, antiscalants help maintain operational efficiency and extend the lifespan of critical components. Regular efficacy testing of antiscalants is essential for ensuring their optimal performance across … Read more
Reverse Osmosis (RO) membranes play a critical role in engineering industries, particularly in water treatment processes. They are essential for ensuring the purity of water used in various industrial applications, from cooling systems to chemical production. However, improper maintenance of these membranes can lead to significant, unexpected costs that go beyond mere replacement expenses. These … Read more
Antiscalants play a crucial role in water treatment systems by preventing the formation of scale, which can impair system performance and reduce efficiency. However, the effectiveness of antiscalants can vary depending on the water chemistry. To ensure optimal performance, it’s essential to conduct efficacy testing tailored to the specific water chemistry in which the antiscalant … 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 damage to the membrane is a common phenomenon. The physical damage could be such as increasing salt passage, a 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, mainly silica, where colloidal … Read more
