| Dissolved Solids | >96% |
| Microorganisms | High Efficiency |
| Organic Substances | High Efficiency |
Pre-Filtration
Pre-filtration is the first step in the purification process of a reverse osmosis system. It involves removing larger particles such as sediment, rust, and other visible impurities that could clog or damage the RO membrane. This stage often includes sediment filters and carbon filters. The carbon filters are particularly important as they remove chlorine, which can otherwise degrade the RO membrane over time. According to WECO Filters, the carbon filter for chlorine removal protects the membrane and ensures that the system functions effectively by preventing increased total dissolved solids (TDS) passage after exposure to chlorine.
Post-Filtration
After the water has passed through the RO membrane, it may still contain some residual contaminants. The post-filtration stage is designed to trap these escaped particles. This stage often includes additional carbon filters or polishing filters to refine the water quality further. These filters are responsible for removing any odors or flavors that the water may have acquired, ensuring that it is pleasant to drink (Peninsula Water).
The combination of these components results in a multi-stage process that delivers clean, safe, and great-tasting water right to your tap.
