After microscreening, there should be a significant reduction in _________.

After microscreening, there should be a significant reduction in _________.

• A. Turbidity
• B. Algae
• C. Iron and Manganese
• D. Undesirable Dissolved Gases

Answer: (B)

The main idea is that microscreening physically removes suspended particles, including algae, from the water as it passes through fine screens. Algae are cells large enough to be captured by the screen openings, so their numbers drop sharply after microscreening. This direct removal of algae is the most noticeable effect, which is why reducing algae is the best answer. Dissolved gases aren’t affected by screening, and iron and manganese are typically addressed by oxidation/filtration rather than by microfiltration screens. Turbidity comes from a variety of suspended solids, including algae, so it will lessen too, but the standout, direct reduction from microscreening is the algae itself.
