Explanation:
The speed of the flowing water, waves caused by the winds and also by the propulsion of the water itself, the atmospheric oxygen gets dissolved in the water. Algae and aqautic plants including the microalgae produce oxygen through photosynthesis which gets dissolved in the river water thereby cleaning it.
Answer:
Running water is able to purify itself through a process called self- purification. The ability of the river to purify itself is called this. As rivers move downstream, certain processes work to make it.
Explanation:
Filtration is usually very good because each collection pipe is protected by a layer or sand and gravel which filters out sediment. As the water moves from the stream to the trenches, bacteria are filtered from it and the result is clean river water.
River water usually contains fine sediment particles in suspension. The water can be passed through filtration materials, like sand, to remove the fine sediment. Filtering the water also tends to remove bacteria.
