Title: Noboru Hayakawa: Innovator in Environmental Technology
Introduction
Noboru Hayakawa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to environmental technology, particularly in wastewater treatment. With a total of 3 patents to his name, Hayakawa's work focuses on innovative methods to enhance the efficiency of wastewater management.
Latest Patents
One of Hayakawa's latest patents is the "Activated Sludge Method." This method effectively removes nitrogen and phosphorus from wastewater by utilizing activated sludge that contains aerobic bacteria. The process involves continuously and gradually feeding wastewater into a treatment basin containing the sludge, forming a mixed liquor. A cycle of agitating and aerating steps is repeated at least twice, with each cycle completed within two hours. The agitating step creates an anoxic condition, allowing denitrification to occur, while the aerobic bacteria release phosphorus in the subsequent anaerobic condition. During the aerating step, nitrification takes place as the bacteria excessively ingest phosphorus from the mixed liquor.
Another notable patent is the "Centrifugal Thickener." This invention features a truncated-cone shaped rotary barrel with a filter along its inner surface. The rotary barrel has a vertical angle of 40 to 80 degrees, and the filter contains openings sized between 10 to 40 microns. This design enhances the efficiency of thickening processes in wastewater treatment.
