WATER PURIFY SYSTEM USING PLASMA UNDERWATER DISCHARGE

摘要

PURPOSE: A water treatment apparatus using the plasma underwater discharge is provided to process organic matters which are not floated or precipitated, and to reduce the water treatment time. CONSTITUTION: A water treatment apparatus includes a flocculant insertion unit(100), a discharge unit(200), and a floc collecting unit(300). The discharge unit firstly stirs object water for 1 minute in 200 rpm after inserting a flocculant to form coagulants by the coagulation of contaminants, and generates bubbles by the plasma underwater discharge. The floc collecting unit removes floc combined to the bubbles, and the floc precipitated by the growth of the coagulants, and secondly stirs the object water for 20 minutes in 30 rpm.
