  Reverse Osmosis technology provides an efficient and reliable method for purifying water for various purposes). It can remove impurities such as salts, minerals, and other contaminants as well as microbial contaminants from the Membrane. Water molecules pass through RO membranes despite dissolved solids and other contaminants being rejected by the membrane. RO membranes are basically thin, dense, and semi-permeable membranes. However, the major significant challenge in Reverse Osmosis System is Scaling. Why does it happen? The formation of scales on the RO (Reverse Osmosis) membrane is primarily caused by the presence of certain dissolved minerals and salts in feed water. Scale refers to the accumulation of mineral deposits, such as calcium carbonate, calcium sulphate, and silica which can severely impact the efficiency and the lifespan of the RO membrane. RO Membrane scaling may lead to cause ·          Excessive Energy Consumption ·          Membrane gets clogged ·     

  Industrial wastewater contains higher levels of suspended solids and organic materials. These suspended solids are stabilized by negative electric charges, causing them to repel each other. Rather than settling, these particles are kept in suspension by repulsion. In such cases, chemical treatment is required to neutralize the charges on colloidal particles, as the solids cannot be separated easily with conventional filtration or settling methods . On chemical dosing, mainly polyelectrolytes, there undergo two very basic working mechanisms i.e., coagulation and flocculation . Coagulation is the neutralization of charges on suspended particles, leading to their destabilization and subsequent aggregation. Flocculation helps to fill the gaps between the destabilized particles, allowing them to make larger, denser flocs, which can be easily separated from the treated water through sedimentation. The efficiency of this process depends upon the coagulant type, dosage, pH value, temperat
