Title: Takashi Fujiwara: Innovator in Waste Water Treatment Technologies

Introduction

Takashi Fujiwara is a notable inventor based in Ashina-gun, Japan. He has made significant contributions to the field of waste water treatment, holding a total of 3 patents. His innovative approaches focus on environmentally friendly methods that utilize biological processes to treat waste water.

Latest Patents

One of his latest patents is a "Method and apparatus for biologically treating waste water containing fluorine." This invention employs microorganism-containing sludge to treat waste water without relying on chemical reactions. The treatment tank consists of an anaerobic part with sludge containing microorganisms and an aerobic part that communicates with it. Waste water and biological excess sludge are introduced into the anaerobic section, where microorganisms treat the water. The treated water is then filtered through a membranous separation device in the aerobic part. This method enhances the microorganisms' ability to concentrate fluorine and other substances present in the waste water.

Another significant patent is the "Method for waste water treatment using charcoal biologically activated." This apparatus features a tank with a contact circulation part containing Bincho charcoal and a sprinkling circulation part above it. The design includes air lift piping to move treatment-object water and a water-sprinkling tube to distribute it. The system also incorporates an aquatic plant cultivation bed and air-diffusing tubes for malodorous gas introduction. The Bincho charcoal and black coal adsorb surfactants and colorants, which are then decomposed by microorganisms, effectively addressing malodorous gas.
