🔍 Key Concepts

• operation of a flash evaporator and how brine level is controlled • the role of the brine pump versus the distillate pump • how pump speed or failure affects liquid level in a tank or chamber

💭 Think About

• Think about which component is supposed to REMOVE concentrated brine from the evaporator. What happens to level if that removal is reduced or stopped? • For each choice, ask yourself: does this condition increase or decrease the rate at which brine leaves the unit? • Separate in your mind what handles the salt-concentrated brine side and what handles the fresh distillate side. Which one directly affects brine level?

✅ Before You Answer

• Identify which pump actually carries brine overboard or to discharge — brine pump or distillate pump? • Decide whether higher flow rate out of the brine side makes level go up or down. • Check which option would most likely REDUCE or STOP brine discharge from the evaporator, allowing level to rise.
