🔍 Key Concepts

• Osmosis and reverse osmosis – how water naturally moves across a semi‑permeable membrane from low to high salt concentration • Osmotic pressure – what it is, and why it must be overcome to reverse the natural process • Role of pre-filters and chemical pretreatment versus the high‑pressure pump in an RO system

💭 Think About

• Ask yourself: What natural process are we trying to "reverse" in a reverse osmosis unit, and what kind of pressure is needed to do that? • Which system components (pre-filters, chemical treatment, membrane) are mainly for protecting/conditioning the water, and which component actually drives water across the membrane? • Is the 750–1200 psig range more likely chosen to push water through a simple filter element, or to counter a fundamental physical pressure related to salt concentration?

✅ Before You Answer

• Clarify in your mind what osmotic pressure means and how it relates to salt concentration on each side of a membrane. • Distinguish between mechanical filtration (strainers, cartridge filters, etc.) and membrane separation in an RO plant. • Verify which part of the system truly needs hundreds of psi to function, and which parts typically operate at much lower pressures.
