The principle is 'dilution': with the first addition of clean water to dirty water, the dirty water becomes less dirty because it is diluted by the clean water. With the continued addition of clean water to dirty water, eventually the dirty water will be completely diluted and there will be no dirty water left; it will all be replaced by clean water.
In ancient times, humans often relied on natural filtration methods to clean dirty water. They would use layers of sand, gravel, and charcoal, sometimes combined with organic materials like mud or plant matter, to filter out impurities. Additionally, they sometimes introduced aquatic insects or small organisms that could help break down contaminants. This rudimentary approach allowed them to improve water quality before consumption.
