a) Reverse Osmosis Cell with Recycle Sea water is to be desalinized by reverse osmosis with brine recycling at following plant scheme shown figure 1. For the given plant scheme and data, answer the following [12 Mar Feed (F) (M) 1000 kg/h sea water 3.3% salt 3.9% Salt Recycle Brine (R) 6% Salt Reverse Osmosis Cell (W) Brine waste (B) 6% Salt Desalinised water (D) 475 ppm Salt [Figure 1: Recycled plant schematic for task 1a)] (i) Calculate the rate of brine waste (B) (4 Marks) (ii) Calculate the rate of desalinized water (D) (4 Marks) (!!!) Calculate the ratio of Recycled stream (R) to the Reverse osmosis cell outlet (W) flow (4 Marks)
