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

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

One of the India’s leading power generation company used to rely more on traditional water treatment tools for boiler feed water treatment. So, system and setup was developed in accordance to that. The company’s power generation setup in South India had tried reverse osmosis + EDI treatment on boiler feed water for the first time. … Read more

Large Automotive manufacturer in India was operating traditional ETP (Effluent Treatment Plant) with UF (Ultra Filtration) and RO (Reverse Osomosis), for treated water recycling since 5 years. Last year, they modified their effluent treatment plant and adopted MBR (Membrane Bioreactors) based treatement. Naturally, being latest trend they were expecting better performance and lesser footprint. But, … Read more
