METHOD TO CLEAN HEADWATERS Russian patent published in 2012 - IPC E02B15/04 

FIELD: ecology.

SUBSTANCE: method includes accumulation of contaminants in an area of water, their separation from streams and accumulation in a settling tank, water cleaning and discharge of cleaned water into the river. Water is cleaned in the settling tank arranged in the river's loop. The river's loop is separated from its artificial cutoff by a waterproof dam and in the upper river and by a filtering dam in the lower river. The filtering dam is equipped with a flooding sluice. In the settling tank along the length there are transverse, floating, waterproof, movable links installed for water overflow at the river bottom that divide the setting tank into zones. In these zones there are aquatic plants and microbial strains promoting biological treatment of water from different types of contamination.

EFFECT: higher efficiency of headwaters cleaning.
