Title:

METHOD OF PURIFYING WATER AREA

Document Type and Number:

WIPO Patent Application WO/2006/121074

Kind Code:

A1

Abstract:

It is intended to provide a method of purifying a water area whereby organic sludge at the bottom of the water area can be efficiently cleaned up and water qualities can be purified while neither requiring a complicated apparatus nor exerting undesirably effects on the natural environment. An aquafarming area (80) is constructed by a preserve (50), which consists of a raft (51) putting on a certain sea area and a net (52) provided under the sea below it, and a controlling system (70) formed on a raft (71) located adjacent to the preserve (50). A large number of red sea breams (53) are fed within the net (52) in the preserve (50). A microbubble generator (1) is provided in the seawater in the preserve (50) and a large amount of capitellidae (55) are distributed at the bottom (54a) of the sea area in which the preserve (50) is formed. By supplying electricity and air from a power generating machine (72) and an air pump (73) on the raft (71) into the microbubble generator (1), seawater containing microbubbles (NB) is supplied into the seawater (W) in the preserve (50).
