Relationships with occupations
Essential knowledge
Deinking processes is an essential knowledge of the following occupations:
Froth flotation deinking operator: Froth flotation deinking operators tend a tank that takes in recycled paper and mixes it with water. The solution is brought to a temperature around 50°C Celsius, after which air bubbles are blown into the tank. The air bubbles lift ink particles to the surface of the suspension and form a froth that is then removed.
Wash deinking operator: Wash deinking operators operate a tank where recycled paper is mixed with water and dispersants to wash out printing inks. The solution, called a pulp slurry, is then dewatered to flush out the dissolved inks.
Optional knowledge
Deinking processes is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.
Tissue paper perforating and rewinding operator: Tissue paper perforating and rewinding operators tend a machine that takes in tissue paper, perforates it, and rolls it up to create various types of sanitary paper.
Paper pulp moulding operator: Paper pulp moulding operators tend a machine that moulds paper pulp in various shapes, usually for use in lightweight but sturdy packaging material, such as egg boxes.
Paper mill supervisor: Paper mill supervisors coordinate and monitor the operations at a paper mill during production of products such as corrugated board, cardboard boxes or padded envelopes. They ensure that production targets, such as quantity and quality of products, timeliness and cost-effectiveness can be achieved. They have a clear overview of ongoing processes, and take quick decisions to resolve problems.
Digester operator: Digester operators, or cooks, cook wood chips with soda ash or acid to separate the wood pulp from unwanted constituents. They test the resulting solution.
Pulp control operator: Pulp control operators operate and monitor multi-function process control machinery and equipment to control the processing of wood, scrap pulp, recycable paper and other cellulose materials in the production of pulp. They set up, operate and maintain the machinery, analyse the production results and adjust the process when necessary.
