Profession 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.

Personality Type

  • Realistic / Conventional

Knowledge

  • Deinking processes

    Various deinking processes such as flotation, bleaching, and washing. These are used to remove ink from the paper in preparation for producing new paper.

  • Types of pulp

    Kinds of pulp are distinguished based on their fibre type and the specific chemical processes through which they were created.

  • Types of paper

    The different criteria used to determine differences in paper types such as coarseness and thickness, and the different fabrication methods and wood types from which the types of paper stem.

  • Quality standards

    The national and international requirements, specifications and guidelines to ensure that products, services and processes are of good quality and fit for purpose.

Skills

  • Wear appropriate protective gear

    Wear relevant and necessary protective gear, such as protective goggles or other eye protection, hard hats, safety gloves.

  • Conform to health and safety regulations

    Carry out all work in accordance with relevant environmental and health and safety legislation, risk assessment requirements and company policies. Take the necessary health and safety precautions during work including posture the body well, safely operate tools and machinery, and wear the right clothes and protection for the climate.

  • Use deinking chemicals

    Handle surfactants or deinking chemicals, which remove ink from fibres. Chemicals such as hydroxides, peroxides, and dispersants are used in processes such as bleaching, flotation, washing, and cleaning. Amongst these non-ionic and electrolyte surfactants are the most important.

  • Separate ink

    Absorb the ink from the substrate, which separates solid particles from liquid material by detergency. This facilitates the separation of ink from fibre.

  • Monitor chemical process condition

    Monitor the conformity of the chemical process, checking all indicators or warning signals provided by the instruments such as recording instruments, flowmeters and panel lights.

  • Work safely with chemicals

    Take the necessary precautions for storing, using and disposing chemical products.

  • Supply machine

    Ensure the machine is fed the necessary and adequate materials and control the placement or automatic feed and retrieval of work pieces in the machines or machine tools on the production line.

  • Concentrate pulp slurry

    Measure the weight and concentration of the pulp slurry for further processing and storage by using disk filters and calculating slurry density with specific formulas.

  • Set up the controller of a machine

    Set up and give commands to a machine by dispatching the appropriate data and input into the (computer) controller corresponding with the desired processed product.

  • Tend deinking tank

    Monitor the flow of waste paper and set up the controller of the tank in which the paper is mixed with water and heated to a high temperature. Skim the ink froth forming on the surface.

  • Work safely with machines

    Check and safely operate machines and equipment required for your work according to manuals and instructions.

  • Monitor automated machines

    Continuously check up on the automated machine's set-up and execution or make regular control rounds. If necessary, record and interpret data on the operating conditions of installations and equipment in order to identify abnormalities.
