Treatment of chlorinated organics in bleached Kraft mill effluents by activated sludge process
Ataberk, S; Gökçay, Celal Ferdi (1997-01-01)
Combined effluents from a bleached Kraft pulp mill using annual plants were treated in a lab-scale activated sludge (AS) system. The effects of operating solids retention time (SRT) and concentration of additional carbon source on AOX removal were investigated. Higher AOX removals (30%) were observed with long SRTs, 99% of which was pure metabolization. As SRT was decreased AOX removal efficiency also decreased (4%) and principal AOX removal mechanism changed to adsorption onto wasted biomass. The AOX remov...
Treatment of organic chlorine in pulping effluents by activated sludge
Demirbas, G.; Gokcay, C.F.; Dilek, Filiz Bengü (1998-09-25)
A model activated sludge (AS) plant was fed by pulping effluents from a straw and reed processing paper works. The model was initially operated to simulate a dedicated treatment plant by continuously receiving chlorinated effluents from the pulp bleachery. In this simulation cycle the model activated:sludge was seeded only once during start-up and did not receive any domestic sewage after that. A carbon source was added in some of the experiments to bring up the organic content. In the second simulation cyc...
Treatment of pulping effluents by using alum and clay - Colour removal and sludge characteristics
Dilek, Filiz Bengü (2001-01-01)
The effect of clay addition during alum coagulation, on the removal of colour from pulp-and-paper industry wastewaters, was investigated. Four types of clay, namely beige-and brown-sepiolites, calcium- and sodium-bentonites of different mesh sizes were used, Different quantities of alum and clay were applied, either singly or in combination, to the effluents of the wood-based pulp-and-paper mill. Colour of the treated wastewater, the sludge volume index (SVI) and sludge cake resistance (SCR) of the sludge p...
Treatment of softwood bleacbery effluents by Penicillium camemberti in anaerobic jars
Taseli, BK; Gökçay, Celal Ferdi (2005-01-01)
Penicillium camemberti was found to be very effective in treating softwood pulp bleaching effluents and chlorinated model compounds like PCP, 2-chlorophenol and trichloroacetic acid. This paper examines the ability of Penicillium camemberti to degrade softwood pulping and bleaching effluents in anaerobic jars. Softwood chlorinated pulping and bleaching effluents inoculated with Penicillium camemberti (20 ml in 25-ml universal tubes) were incubated under anaerobic conditions (oxoid anaerobic jars) at 25 degr...
Treatment of reactive dyeing wastewater and recovery of brackish water by applying ultrafiltration
Erkanlı, Mert; Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep; Department of Environmental Engineering (2016)
Reactive dyeing wastewaters (RDW) originating from textile industry are highly colored and have high total organic carbon (TOC), turbidity and salinity content. Ultrafiltration (UF) scenario suggested here aims to keep salt in permeate and reuse resulting permeate in dyeing process. For this purpose, RDW samples were treated with 5 kDa PES and 2 kDa Thin Film GE Osmonics UF membranes. After single stage filtrations, two stage “5 kDa+5 kDa”, “5 kDa+2 kDa” and “2 kDa+2 kDa” applications were carried out at 2 ...
