pah removal from Black Sludge from aluminium industry by flotation using non ionic surfactants
Environmental Technology, 2006Co-Authors: Aurelie Dhenain, Jeanfrancois Blais, Guy Mercier, Mario BergeronAbstract:The valorization of Black Sludge is an environmental problem of the aluminium industry because of Polycyclic Aromatic Hydrocarbon (PAH), fluoride and alumina contents. A soil washing operated in a cell flotation with non-ionic surfactants (Brij 35, Igepal CA-720, Triton X-100, Tween 80) at different concentrations has been tested in order to remove the PAH (benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(j)fluoranthene, benzo(k)fluoranthene, fluoranthene) detected in Black Sludge. The Tween 80 at 0.5% gave the best results with PAH removal rates between 35 and 50%. These percentages remain low due to the presence in large quantity of fine solid particles (45%) in the PAH concentrate produced by the flotation process. The substitution of the cell flotation by a column flotation allowed the reduction of this problem. Thus, the PAH removal rates reached 60%. This removal yield has been obtained with the lowest wash water flow-rate (150 ml min−1) and pulp total solids (10% p p−1) tested.

Cement type composite panels manufactured using paper mill Sludge as filler
'Elsevier BV', 2017Co-Authors: Çavdar, Ayfer Dönmez, Yel Hüsnü, Boran Sevda, Peşman EmrahAbstract:The aim of this study was to evaluate some physical and mechanical properties of the paper mill (PMS) and spruce planer shaving added cement boards. Also the effect of Sludge type in consequence of waste water treatment technique on properties of wood-cement boards (WCB) was investigated. The wood/cement ratios were used as 1/3, based on the oven dry weight for the WCB manufacture. PMS was used up to 20% wt of total composite based on organic (wood) and inorganic (cement) amounts. Black Sludge has shown more improvement than grey Sludge on properties of WCBs, which indicates the anaerobic waste treatment technique is more effective for additive in WCB. The modulus of rupture and elasticity values of the WCBs with 5% of grey Sludge, 5% and 10% of mixture of grey and Black Sludge were acceptable limits according to EN 634-2 standard. The mechanical strengths of all WCBs with Black Sludge were found above the specified EN standard. This suggests that PMS depending on Sludge type may be used up to 20% wt of total composite weight for the commercial production of WCBs, which. could expand the raw material base for this panel product.
