| Typical Flow Diagram for Pure Water System | ||||||||||||
| Process Description: Raw water is feed into pretreatment system which comprise of sand filter and activated carbon filter. Multimedia sand filter is used to produce higher water quality compare to dual-media sand filter. Mud and suspended solids will be removed from the raw water. Carbon adsorption is used for removal of chlorine, refractory organic compounds and inorganic compounds. The pretreated water is polished with micron cartridge filter prior to demineralization system. There are several options for demineralization system which are Mixed Bed Water Deionizer (MB), Double Pass Reverse Osmosis (DPRO), Single Pass Reverse Osmosis (SPRO) and Combination of Reverse Osmosis & Mixed Bed Deionizer (ROMB). |

| Mixed Bed Water Deionizer (MB) MB consists of single resin column where both the cation resin and anion resin are placed in the vessel. Raw water contains dissolved solids comprise of cationic and anionic salts; where the anionic and cationic will exchange with its H+ and OH- on its cation and anion resin respectively. The ion H+ and OH- released from the resins combine to form H2O (water). Reverse Osmosis System  |
