The quantity and density of brine discharged from the last effect of a flash type evaporator should be kept at a constant value so as to __________.

🔍 Key Concepts

• Flash type evaporator operation – how multiple effects work and where brine is removed • Relationship between brine density/concentration, distillate quality, and scaling • How constant discharge conditions affect overall efficiency of an evaporator system

💭 Think About

• Think about what happens inside all the effects if the brine from the last effect suddenly becomes much more or much less concentrated. Which parts of the plant would be most affected? • Which option deals with the overall performance of the distilling plant (not just temperature or just the first effect)? • Consider which choice describes a result that is realistically achievable in practice and routinely controlled by operators, versus an ideal that is hard to reach all the time.

✅ Before You Answer

• Ask: Does this option connect brine concentration directly to both the purity of the fresh water and how effectively the plant runs? • Check which choices refer only to a single component (like the first effect or outlet temperature) instead of the whole system. • Eliminate any option that promises something that is practically impossible to guarantee just by holding brine density constant.

Question 1 of 27070

The quantity and density of brine discharged from the last effect of a flash type evaporator should be kept at a constant value so as to __________.

prevent scale accumulation in the first effect heat exchanger surfaces

maintain a constant distillate outlet temperature

ensure distillate quality and distilling plant efficiency

prevent any salinity in the distillate produced
