The Imhoff tank was designed by Dr. Karl Imhoff in Germany in which year?

Explanation:
The main idea is when the Imhoff tank was first designed. Karl Imhoff, a German engineer, introduced this two‑chamber primary clarifier in the early 20th century to improve solids removal from wastewater. The design places a sludge chamber beneath the settling compartment so solids can settle and be withdrawn separately while the clarified liquid overflows to the next stage. This origin date is around 1906, which is why that year is the correct choice.
