Title: Decomposition/separation unit for organic matter or the like in water
Inventor: IMAI MASAO
IPC: C02F1/48
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To perform the decomposition/separation of organic matter in raw water without using any chemical agent and to produce purified water by electrifying raw water in an electric field space between a small-diameter pipe and a large-diameter pipe and jetting the water in the electrified state as it is, from a small hole of any one of these pipes to the outside in a nozzle-like shape, in the unit. SOLUTION: The decomposition/separation process using this unit comprises introducing raw water into a small-diameter stainless pipe A, then forcedly allowing the raw water to flow out from the pipe A into an electric field space between the pipe A and a large- diameter stainless pipe B through a small hole formed in the pipe A, and further, jetting the raw water from a small hole formed in the pipe B, wherein these pipes A and B are also used as electrodes, respectively. This process is effective in removing Microcystis algae and other pollutants, which are generated in a water system polluted by eutrophication. By only feeding water passed through this nozzle/electric-field unit to a section having a recovery function, the algae and other pollutants can be separated in an easily recoverable state.  The purified water being free from the algae and other pollutants, has properties such that a plant can easily absorb necessary components for it from the purified water. By using the purified water thus produced, an aquatic plant which is a fundamental element for regenerating a healthy ecological system, can be grown.
