🔍 Key Concepts

• Reverse osmosis (RO) basics – how pressure affects water flow through the membrane and brine flow across the membrane surface • Brine back pressure regulator – its role in maintaining correct operating pressure and flow across the membrane to prevent damage or fouling • Relationship between pressure, flow, and permeate (fresh water) production in an RO system

💭 Think About

• Think about what happens to the membrane surface if the brine flow becomes too slow versus when it is kept at a healthy sweeping velocity • Consider how very high pressure on the concentrate (brine) side might affect the mechanical integrity of the membrane elements • Ask yourself: in an RO unit, do you usually increase or decrease pressure to get more fresh water, and what side effect does that have on the membrane?

✅ Before You Answer

• Verify what too low brine back pressure does to the brine flow rate over the membrane surface (and how that relates to fouling vs. damage) • Verify what too high brine back pressure does to overall system pressure and risk to the membrane modules (and how that affects fresh water output) • Confirm the usual relationship: as operating pressure goes up, how does permeate (fresh water) production change in a properly functioning RO unit?
