🔍 Key Concepts

• Reverse osmosis (RO) basics – how pressure forces seawater through a semi‑permeable membrane to produce freshwater • Membrane fouling – what happens to flow paths inside the membrane when they become clogged with scale, bio‑growth, or dirt • Relationship between flow resistance, pressure, and production rate in a pressurized filtration system

💭 Think About

• Imagine slowly clogging the tiny passages in the membrane: what happens to the ease of flow, and what happens to the pressure needed to push water through? • In a normal RO unit, if you partially close a valve on the discharge side of a pump, what happens to system pressure and to the actual volume of water getting through? • Think of a clean filter versus a dirty filter in any system: how do flow rate and pressure typically change as the filter gets dirtier?

✅ Before You Answer

• Be clear on whether clogging (fouling) makes water pass more easily or more difficultly through the membrane. • Decide whether more difficulty in flow tends to raise or lower the required feed pressure from the high‑pressure pump. • Match the combination of changed pressure and changed freshwater output that fits a membrane with increased resistance to flow.
