Q

With regards to a reverse osmosis unit, what is the BEST indication that the membrane module is damaged and is no longer semi-permeable and allowing the solute to pass through?

🔍 Key Concepts

• Reverse osmosis (RO) principle – fresh water passes through a semi‑permeable membrane, salts/solute are rejected • What happens when a membrane is damaged – think about how salt and pressure behave if the barrier is compromised • Difference between flow/pressure problems and water quality (salinity) problems

💭 Think About

• If the membrane is no longer properly semi‑permeable, what changes most directly: the amount of water produced, the salt content of the product, or the pressure on the brine side? • Which option describes a condition you would see if salts that should be rejected are now passing through into the fresh water outlet? • Which choices could also be caused by normal fouling or operating issues (like clogged membranes or low feed pressure), not necessarily a torn or damaged membrane?

✅ Before You Answer

• Focus on product water salinity, not just quantity of water made • Decide which answer clearly shows that salt is getting through the membrane into the fresh water stream • Eliminate any options that could occur with a healthy but dirty or under‑fed membrane (e.g., just lower production or pressure changes).
