リクリエーション施設用及び装飾的な使用のための水槽の中の水の効率の良い濾過プロセスであって、濾過が少量の水に対して実施され、水槽の水の全量に対しては行われないプロセス

摘要

An efficient filtration process of water from a tank is performed over a small volume of water and not on the totality of the water from the tank. The process includes emitting ultrasonic waves in the tank; and adding a flocculant agent to the water. The tank bottom is covered with a suctioning device which suctions a water flow with flocculated particles, discharging to a collecting effluent line and the effluent flow of the suctioning device is filtered from the collecting effluent line. Filtered flow is returned to the tank. A suctioning device is used in the efficient filtration process.
