Relationships with occupations
Essential skill
Concentrate pulp slurry is an essential skill of the following occupations:
Paper machine operator: Paper machine operators tend a machine that takes in pulp slurry, spread it out over a screen, and drains out the water. The drained slurry is then pressed and dried to produce paper.
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.
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.
Optional skill
Concentrate pulp slurry is optional for these occupations. This means knowing this skill may be an asset for career advancement if you are in one of these occupations.
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.
Artisan papermaker: Artisan papermakers create paper slurry, strain it on screens, and dry it manually or using small scale equipment.
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.
