Title: Mieko Nishi: Innovator in Membrane Technology
Introduction
Mieko Nishi is a prominent inventor based in Ibaraki, Japan, known for her significant contributions to membrane technology. With a total of four patents to her name, she has made remarkable advancements in the field, particularly in the development of spiral membrane elements.
Latest Patents
Mieko Nishi's latest patents include innovative designs for spiral membrane elements. One of her patents describes a spiral membrane element that features a restricted outer diameter while being capable of reducing operational energy. This element consists of multiple membrane leaves, each containing a permeation-side flow-channel member situated between opposing separation membranes. Additionally, a supply-side flow-channel member is interposed between any two membrane leaves, along with a perforated central pipe that supports the winding of the membrane leaves and the supply-side flow-channel member. The sealing part of this design prevents the mixing of the supply-side flow-channel member with the permeation-side flow-channel member, achieving an efficiency index E ranging from 0.005 to 0.10, with the thickness of the supply-side flow-channel member varying from 10 to 110 mil.
Another patent by Nishi presents a spiral membrane element that maintains a restricted outer diameter while enhancing the effective membrane area, thereby reducing operational energy. This design also includes multiple membrane leaves, a permeation-side flow-channel member, and a supply-side flow-channel member, all wound around a perforated central pipe. The sealing parts in this patent utilize adhesive to seal the two-side end parts of each membrane leaf, with the thickness of the sealing parts ranging from 390 to 540 micrometers.
