ULTRAPURE WATER PURIFICATION SYSTEM IN KARACHI

Designed for today�s laboratories

System Description
The LabPure� system is a four (4) stage reverse osmosis de-ionization system.
1. First, the incoming feed water is passed through a 5 micron sediment pre-filter. This filter is required to remove excess turbidity (particulate matter) that may cause the membrane to plug.
2. The second stage of filtration is a 5 micron carbon block pre-filter. This filter removes organics and chlorine from the feed water that can damage the membrane.
3. The third filtration stage of the system is a high rejection, thin film composite (TFC) reverse osmosis membrane. It removes at least 98% of most inorganic salts, all micro-organisms and almost all high molecular weight organics in the water.
4. The fourth stage moves water through a Mixed-Bed Multi-Layer Deionization Cartridge. Mixed-Bed Multi-Layer Deionization Cartridges are fabricated with semi-conductor grade resins for highest possible purity water. They are capable of producing 18 mega-ohm-cm resistivity water. They are the first DI cartridges designed to reduce silica, nitrates and phosphate levels in the low ppb range. These newly formulated cartridges far exceed the performance of previous cartridges, offering enhanced contaminant removal, longer life and higher purity.
