Introduction The concepts of â€Å"osmosis” and â€Å" throwback osmosis” have been know for many years. Studies on osmosis were carried out as archean as 1748 by the French scientist Nollet. Many researches account on reverse osmosis trunk and desalination of seawater, close to of them using hollow fiber or loop wound membrane in their research [1].Effects of unalike operating parameters (feed water concentration, temperature, pressure and flow rate) on membrane performance were examined using RO clay [2]. esthesia of diverse design parameters (internal diameter, total number of tubes) on the recovery ratio was also studied [3]. as well predicting the performance of RO membrane, several models for mass transport in membrane have been developed such as solution-diffusion model, models from irreversible thermodynamics, etc. [4 and 5].Simulation and optim ization of various RO membrane, take on on concentration polarization in RO system and many case study on alert plant was reported. Although many studies were conducted on reverse osmosis membrane, hollow membrane was rarely investigated. This study is aimed at investigation the tubular RO module. The performance of this membrane on different operating parameters has been examined and the best operating condition of RO system with the best permeate quality were utilised to seduce drinking water from seawater. 2. Chemicals and Methods The feed stock for reverse osmosis system is the seawater.\r\n'
