Part per million match Dissolved Solid Membrane area Pressure in the feed, retentate and get across streams 1. Introduction The concepts of osmosis and reverse osmosis ca-ca been known for umteen years. Studies on osmosis were carried step up as early as 1748 by the French scientist Nollet. Many explorees report on reverse osmosis arrangement and desalination of seawater, Most of them using unearth fiber or spiral wound membrane in their research 1.Effects of different operating parameters (feed water concentration, temperature, pressure and flow rate) on membrane performance were examined using RO system 2. Sensitivity of different design parameters (internal diameter, organic number of tubes) on the recovery ratio was also studied 3. anyhow 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 optimization of unlik e RO membrane, study on concentration polarization in RO system and many case study on existing plant was reported. Although many studies were conducted on reverse osmosis membrane, tubular membrane was rarely investigated. This study is aimed at investigate the tubular RO module. The performance of this membrane on different operating parameters has been examined and the outstrip operating condition of RO system with the best permeate quality were utilise to produce drinking water from seawater. 2. Chemicals and Methods The feed stock for reverse osmosis system is the seawater.
