Development of a new disk filter concept for improved paper stock dewatering and better process water management

Kadant is a leading supplier of the pulp and paper industry. As such, Kadant is developing a new disk filter**design and will build a prototype. This prototype will have 2 or 3 disks compared to up to 30 for a commercial**unit. The disks of the prototype will have the same diameter as the future commercial units. It is essential for**Kadant to fully prove the possibilities of this new concept before commercialization. Operation data must be**gathered in order to establish the performance of the prototype in different conditions. Kadant does not have a**disk filter in its product line to offer to its customer. In order to present a new product to the industry, Kadant**must demonstrate that its new concept is worthwhile. This will be a new product line for Kadant and that will**boost its strong reputation in stock preparation systems. New, improved machinery is also of primer**importance for the Canadian pulp and paper industry which must improve its processes and paper products to**remain competitive. The Canadian paper companies that will invest in new equipment, such as an efficient**disk filter, will take a step in the direction of competiveness and efficiency. The project submitted is to**develop the product technology, and if successful, commercial design and manufacturing could be done in**Kadant facilities and Canadian based sub-contractors as appropriate. This will employ highly qualified**Canadians. Additionally, the installation of new disk filters in Canadian mills will be done by Canadians. The**proposed project is the first major collaboration between Kadant and Innofibre. It is the intent of Innofibre and**Kadant to pursue this development with subsequent projects. Innofibre will expand its expertise about**dewatering equipment which will be transferred to the Canadian industry.
