Title: Morikata Nishida: Innovator in Wastewater Treatment Technologies
Introduction
Morikata Nishida is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of wastewater treatment, holding two patents that showcase his innovative approaches to environmental solutions.
Latest Patents
Nishida's latest patents include a method for removing selenium and a wastewater treatment device. The method for removing selenium involves a valence change step where an oxidant is added to wastewater from a facility that gasifies fuel containing selenium in a reducing atmosphere. This process oxidizes the selenium to change its valence. Following this, a solid-liquid separation step is performed by adding a flocculant to the wastewater, forming a floc that contains the altered selenium, which is then subjected to solid-liquid separation. The wastewater treatment device he developed incorporates a first biological treatment device that utilizes a membrane-separated activated sludge method and a second biological treatment device that employs a biofilm method. It also includes measurement units to assess load concentration and flow rate, along with a control unit that calculates load quantity and adjusts the flow rates accordingly.
