The present invention relates to a complete process for preparation of high flux and salt rejection thin film composite (TFC) reverse osmosis (RO) membrane including process for preparation of support membrane for thin film, process for thin film coating of support membrane by in-situ interfacial polymerization between diamines and trimesoyl chloride, machine design, chemistry and details of process (engineering+chemistry+ambient) parameter at 1&#xd7;100 sqm scale upgradeable to a scale even 10-20 times higher. The produced membrane is characterized by 96% salt rejection and 48 LM-2H 1 flux with 2000 ppm sodium chloride solution at 250 psi pressure and 95% salt rejection and 46 LM2H 1 flux with 35000 ppm sodium chloride solution at 900 psi pressure. The present invention also relates to complete machine design for PSF ultrafiltration membrane casting and coating for TFC membrane production at commercial level.

Modified thin film composite reverse osmosis membrane and a process for preparation thereof

The present invention discloses a nutritious, tasty and affordable drink made from the sap ofseaweed which is readily cultivable. The drink resembles coconut water in appearance and taste and is rich in potassium. It also contains an adequate proportion of the daily requirement of iodine besides many other useful minerals such as magnesium, calcium, sodium, zinc, phosphorous and iron while having low concentrations of toxic elements such as lead and chromium. The process of refining sap, which enables the seaweed drink to be palatable and widely acceptable, besides bestowing adequate shelf life, is also described. The process of preparation is integrated with preparation of carrageenan and plant nutrient thereby making optimum use of the seaweed and minimizing waste.

Method for the preparation of refreshing drink and use thereof

The invention describes the cost effective process for the preparation of a mixture of salts having low sodium salt (health salt) contain and exclusively derived from vegetable sources which have desired sodium chloride: potassium chloride ratio and traces of micronutrients including iodine, said salt is white in color and free flowing in nature.

Low sodium salt of botanic origin
