PAPER
Purification of wastewater generated during the production of paper and cardboard.
In the paper industry, the PRO-PUR Series is used to treat wastewater generated during the paper and cardboard production processes. This water contains a variety of organic and inorganic substances that must be removed before the water is discharged or reused. Here is a detailed analysis:
Substances Treated with PRO-PUR in the Paper Industry
Paper Fibres:
Cellulose: Derived from the processing of wood pulp.
Secondary Fibres: Derived from paper recycling.
Chemical Substances:
Glues and Adhesives: Used in the production of paper and cardboard.
Dyes and Pigments: Present in the waste water from printing and paper colouring.
Chemical Additives: Used to improve the properties of paper (for example, water resistance, gloss).
Suspended Solids:
Particulates: Small particles of paper and cardboard suspended in the water.
Sludge: Derived from the manufacturing processes and wastewater treatment.
Organic Substances:
Lignin: Present in the waste water from the processing of wood pulp.
Sugars and Starches: Deriving from the processing of cellulose.
Other Contaminants:
Heavy Metals: Present in traces in the waste water from paper processing.
Bacteria and Microorganisms: Present in the waste water from paper processing.
