Hylte produces newspaper mainly from mechanical pulp and recycled newspaper, although a small amount of chemical pulp must sometimes be added to the process. The modelled activated sludge basin has surface aerators, operates at neutral pH conditions
The process takes advantage of aerobic micro-organisms that can digest organic matter in sewage, and clump together by flocculation entrapping fine particulate matter as they do so. It thereby produces a liquid that is relatively free from suspended solids and organic material, and flocculated particles that will readily settle out and can be removed.
