🔍 Key Concepts

• Reverse osmosis (RO) pre-treatment filter function – what it removes before water reaches the RO membranes • Pressure drop across a filter – what a rising vs. normal pressure drop tells you about filter condition • Difference between problems caused before the RO membranes (pre-treatment) and at/after the membranes themselves

💭 Think About

• Ask yourself: Which symptom points directly to the condition of the pre-treatment filter itself, not to the RO membranes or overall system performance? • Consider: If the pre-treatment filter starts to clog, what happens to the pressure on the inlet and outlet sides of that filter? How would that show up on gauges? • Think about which option describes a problem that could have several different causes (not just pre-treatment filter) versus one that points specifically to the pre-treatment filter needing service.

✅ Before You Answer

• Identify which answer choice refers specifically to the pre-treatment filter, not the membrane modules • Check which symptom would be read directly from pressure gauges across the filter rather than from water quality or production rate tests • Eliminate any choices that could easily be caused by membrane fouling, pump problems, or salinity control issues rather than the pre-treatment filter alone
