Title: Innovations of Kouji Irie in Sludge Treatment Technology

Introduction

Kouji Irie is a notable inventor based in Ichikawa, Japan. He has made significant contributions to the field of sludge treatment technology. His innovative approach has led to the development of a unique membrane apparatus that addresses common challenges in the treatment of raw liquid.

Latest Patents

Kouji Irie holds a patent for a sludge treatment membrane apparatus. This apparatus features a bubble supplying portion that introduces micro bubbles near the entrance of a flow passage for raw liquid. This design prevents the growth of a gel layer on the membrane surface, allowing for a large filtering capacity while minimizing sludge blockage. The uniform passage of bubbles through the inter-membrane spaces ensures that sludge blocking is evenly mitigated across the entire membrane surface. Additionally, the use of a flat membrane as the filtering medium reduces the frequency of maintenance work required for disassembling and cleaning the membranes. The apparatus also includes an aeration system, a circulating tank, and a filtrate pump. Notably, the decrease in relative density of the raw liquid after bubble treatment creates a natural flow, eliminating the need for a circulation pump and thereby reducing both initial and operational costs.
