Title: Jyri Välimäki: Innovator in Water Treatment Technologies
Introduction
Jyri Välimäki is a notable inventor based in Nokia, Finland. He has made significant contributions to the field of water treatment technologies, holding 2 patents that focus on innovative methods for treating aqueous feeds and dewatering sludge.
Latest Patents
One of Jyri Välimäki's latest patents is a method for treating aqueous feed by dissolved gas flotation. This method is designed for industrial processing of fibrous materials, where the aqueous feed contains both an aqueous phase and solid particulate material. The process involves bringing a flocculant into contact with the aqueous feed, which flocculates the suspended solid particulate material into flocs. These formed flocs are then contacted with gas bubbles, inducing their flotation in a flotation basin. The flocculant used includes a polymer composition with a charge density of at most 1.7 meq/g dry, featuring a cationic synthetic first polymer and a second polymer obtained through polymerization of (meth)acrylamide.
Another significant patent by Jyri Välimäki is focused on the dewatering of sludge from pulp, paper, or board-making processes. This method includes obtaining an aqueous sludge that contains an aqueous phase and fiber material. The sludge undergoes a pre-thickening step to remove a portion of the aqueous phase, followed by a pressing step to further reduce the aqueous content, resulting in dry pressed sludge. A polymer composition with a charge density of at most 1.7 meq/g is added to the sludge before or during the pre-thickening step to enhance the dewatering process.
