Applications-Bleaching Paper & Pulp

Alpha Ozone Pulp production has two main objectives-to separate cellulose fibers from lignin with the minimum of physical damage to the fibers and to remove as much lignin from the fibers as possible. The best paper is produced from long fibres of the highest brightness. Fibers in pulp may be further treated to remove residual lignin and further brighten the resultant papers.


This process results in the release of large amounts of material. Although significant technological advances have reduced emissions to the environment since the 1970s [l], estimated discharges of air pollutants in 1986 were 100 000 tones of particulates, 80 000 tomes of sulphur dioxide 60 000 tomes of carbon monoxide, 15 000 tones of nitrogen oxide, and 12 000 tomes of hydrocarbons [l].


These discharges appear to be widely dispersed into the atmosphere and have not been judged to be of major toxicological significance. About 80% of the pulp and paper mills in Canada discharge their water-borne effluents directly into surface or marine waters. These discharges have been categorized into total suspended solids (TSS), biological oxygen demand (BOD) and toxic discharge. This latter category is based on the proportion of failed acute lethality tests and the flow of discharge from the mill.


Pulp is a dry fibrous material prepared by chemically or mechanically separating fibers from wood, fiber crops or waste paper.


Pulp can be either fluffy or formed into thick sheets. The latter form is used if the pulp must be transported from the pulp mill to a paper mill. Pulp which is shipped and sold as pulp (not processed into paper in the same facility) is referred to as market pulp. When suspended in water the fibers disperse and become more pliable.


This pulp suspension can be laid down on a screen to form a sheet of paper, and this is the primary use for wood pulp. Wood pulp is the most common material used to make paper. The timber resources used to make wood pulp are referred to as pulpwood. Wood pulp comes from softwood trees such as spruce, pine, fir, larch and hemlock, and hardwoods such as eucalyptus, aspen and birch.
