Removal of pharmaceuticals from municipal wastewater by adsorption onto pyrolyzed pulp mill sludge R.N. Coimbra a , V. Calisto b , C.I.A. Ferreira b , V.I. Esteves b , M. Otero a . A charcoal was produced from primary pulp mill sludge and then used for the adsorptive removal of diclofenac, salicylic acid, ibuprofen and acetaminophen. A main aim was to assess the utilization of this material for the tertiary treatment of sewage. For this purpose, the adsorption of the selected pharmaceuticals from the secondary effluent of a sewage treatment plant (STP) was compared with their adsorption from ultrapure water. Differences in the adsorption kinetics and equilibrium were evident between the four pharmaceuticals considered. However, differences between the adsorption from the two aqueous matrixes considered were negligible. It was hypothesized that synergetic microorganism removal compensated the competitive effects in wastewater.

The Paper Industry Technical Association (PITA) is an independent organisation which operates for the general benefit of its members – both individual and corporate – dedicated to promoting and improving the technical and scientific knowledge of those working in the UK pulp and paper industry. Formed in 1960, it serves the Industry, both manufacturers and suppliers, by providing a forum for members to meet and network; it organises visits, conferences and training seminars that cover all aspects of papermaking science. It also publishes the prestigious journal Paper Technology International and the PITA Annual Review , both sent free to members, and a range of other technical publications which include conference proceedings and the acclaimed Essential Guide to Aqueous Coating .
