Commercial Ro Water Systems 250LPH-2000LPH Reverse Osmosis For PLant
When pure water and saltwater are separated by a semi-permeable membrane, water naturally flows toward the saltwater side (osmosis). Reverse osmosis (RO) reverses this flow by applying pressure greater than osmotic pressure to the saltwater side, forcing pure water molecules through the membrane while blocking contaminants. The heart of RO systems—the RO membrane—has 0.0001-micron pores (1/1,000,000 of a human hair), filtering ions and particles larger than 0.3–0.6 nanometers.
For dialysis and lab use, RO alone is insufficient. Two-stage RO + EDI (Electrodeionization) achieves 18.2 MΩ·cm resistivity. EDI combines ion exchange and electric fields to remove ions without chemicals, enabling continuous ultra-pure water production.
Typical 5-stage filtration:
PP Sediment Filter: Traps rust/sand.
Carbon Filter: Adsorbs chlorine/organics (*critical: >0.1mg/L chlorine damages RO membranes*).
RO Membrane: Removes heavy metals, viruses.
Post-Carbon Filter: Improves taste.
Optional: Scale inhibitor to prevent mineral buildup.
