In this study, the ability of algae to treat a wood-based pulp and paper industry wastewater was investigated. Tests were performed in batch reactors seeded with a mixed culture of algae. Under different lighting and initial wastewater strength conditions, changes in COD, AOX and color contents of reactors were followed with time. Algae were found to remove up to 58% of COD, 84% of color and 80% of AOX from pulp and paper industry wastewaters. No remarkable differences were observed in COD and color when light intensity and wastewater strength were changed, while AOX removals were strongly affected. Algal species identification studies revealed that some green algae (Chlorella) and diatom species were dominant in the treatment. The study also showed that algae grew mixotrophically, while the main mechanism of color and organics removal from pulping effluents was partly metabolism and partly metabolic conversion of colored and chlorinated molecules to non-colored and non-chlorinated molecules. Adsorption onto algal biomass was not so effective.

Investigating the effect of solids retention time on pesticides removal in an activated sludge process Kocaman, Kumru; Yetiş, Ülkü; Dilek, Filiz Bengü (2022-10-01) © 2022 Elsevier B.V.The levels of pesticides reaching the biological wastewater treatment plants have been increasing. Operational conditions leading to the most efficient removal of pesticides in these plants should be evaluated first before attempting tertiary-level treatment options. This study investigated the influence of solids retention times (SRTs) on the removal of three pesticides (carbendazim, imidacloprid, and aclonifen) in the activated sludge process. Laboratory-scale reactors receiving these ...
TREATMENT OF EFFLUENTS FROM HEMP-BASED PULP AND PAPER-INDUSTRY .1. WASTE CHARACTERIZATION AND PHYSICOCHEMICAL TREATABILITY Dilek, Filiz Bengü (1994-01-01) This study was conducted to determine the wastewater characteristics as well as the treatment alternatives for the Tafkopru Pulp and Paper Mill in Turkey. The physico-chemical treatability study was conducted by standard Jar-test equipment. The highest COD removal efficiency obtained was 96% for the paper machine, 50% for the alkali extraction and 20% for the bleaching effluents by using alum as coagulant. The colour removal efficiency was around 80% for the alkali extraction effluents.
TREATMENT OF EFFLUENTS FROM HEMP-BASED PULP AND PAPER-INDUSTRY .2. BIOLOGICAL TREATABILITY OF PULPING EFFLUENTS celal ferdi, gökçay; Dilek, Filiz Bengü (1994-01-01) This paper is focussed on the biological treatability studies of pulping effluents from a hemp-based pulp and paper industry. Experiments were conducted by using white fungus, Phanerochaete chrysosporium, in a laboratory batch reactor. It was found that the colour removal efficiency is 75% for pulping effluents in the presence of high concentrations of glucose.
Treatment of olive mill wastewater by different physicochemical methods and utilization of their liquid effluents for biological hydrogen production Eroglu, Ela; Erolu, Inci; Gündüz, Ufuk; Yucel, Meral (2009-04-01) in this study various two-stage processes were investigated for biological hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001. Two-stage processes consist of physicochemical pretreatment of OMW followed by photofermentation for hydrogen production. Explored pretreatment methods were chemical oxidation with ozone and Fenton's reagent, photodegradation by UV radiation, and adsorption with clay or zeolite. Among these different two-stage processes, strong chemical oxidants ...
Treatment of effluents from hemp based pulp and paper industry II biological treatability of pulping effluents Gökçay, Celal; Dilek, Filiz Bengü (IWA Publishing; 1993-10-13) This paper is focussed on the biological treatability studies of pulping effluents from a hemp-based pulp and paper industry. Experiments were conducted by using white fungus, Phanerochaete chrysosporium, in a laboratory batch reactor. It was found that the colour removal efficiency is 75% for pulping effluents in the presence of high concentrations of glucose.
