Technical Bulletin No. 0224: Biochemical Oxidation Characteristics of Cellulosic Fibres in Aqueous Suspension and in the Soil

Successful development of efficient treatment processes for oxidation of non-settleable and soluble constituents has prompted research on other effluent components, such as fibers, since (a) their presence affects biological treatment processes, and (b) they tend to pass through certain biological treatment units relatively unchanged. Further, although there has been rapid growth in use of primary clarifiers to prevent discharge of fibers into both receiving waters and to second-stage biological treatment units, some fiber inevitably escapes removal by clarification and undergoes oxidation adding to the unit loading of treatment devices.
