Biological treatability of pulping effluents by using a Penicillium species

Gökçay, Celal Ferdi
Taseli, BK
Pulp and paper plants are among the most polluter industries. Their effluents are normally treated biologically for standard parameters such as BOD and GOD; but biological treatment is usually not complete. Unconventional parameters unique to these wastes, such as color and organic halides(AOX), are virtually persistent throughout the treatment cycle. A fungus, which is able to affect over 50% AOX and color removal from soft wood pulping bleachery effluents in less than two days of contact, have been isolated and tentatively identified as Penicillum sp.


Biological treatment of paper pulping effluents by using a fungal reactor
Taseli, BK; Gökçay, Celal Ferdi (1999-01-01)
Pulp and paper plants are amongst the most polluter industries in this country and elsewhere. Most of the organic halides (AOX) and colour from pulp bleaching units are discharged to the receiving basins without being fully treated. A fungus, which is able to affect over 50% AOX and colour removals from soft-wood bleachery effluents within two days contact time, have been isolated in this laboratory. Optimum condition for dechlorination by this fungus in batch tests was determined as pH 5.5 and 25 degrees C...
Selective sulfate sorption from boric acid factory process liquor: Chitosan-bentonite biocomposite film synthesis as sorbent
Kaya, Fatih; Ozer, Ahmet (2022-09-01)
Chitosan is a natural polymer that is renewable, biocompatible, and biodegradable. Bentonite is a natural mineral with low environmental effects. For this reason, chitosan- bentonite biocomposite film was synthesized as a sorbent and its characterized by FT-IR, SEM, EDX, CHNS elemental analysis and thermal analysis techniques. The sorbent was utilized for selective sulfate (SO42  ) sorption from boric acid factory process liquor, because one of the most important problems in the boric acid productio...
Biological hydrogen production from olive mill wastewater with two-stage processes
Eroglu, Ela; Eroglu, Inci; Gündüz, Ufuk; Turker, Lemi; Yucel, Meral (2006-09-01)
In the present work two novel two-stage hydrogen production processes from olive mill wastewater (OMW) have been introduced. The first two-stage process involved dark-fermentation followed by a photofermentation process. Dark-fermentation by activated sludge cultures and photofermentation by Rhodobacter sphaeroides O.U.001 were both performed in 55 ml glass vessels, under anaerobic conditions. In some cases of dark-fermentation, activated sludge was initially acclimatized to the OMW to provide the adaptatio...
Catalytic ozonation of synthetic wastewaters containing three different dyes in a fluidized bed reactor
Balcı, Ayşe İrem; Özbelge, Ayşe Tülay; Department of Chemical Engineering (2011)
Environmental regulations have imposed limitations on a wide variety of organic and inorganic pollutants in industrial textile wastewaters. There are several degradation methods used in literature studies. Among these methods ozonation is one of the most considered way to degrade refractory chemicals in textile wastewaters. In recent years, catalytic ozonation as being one of the advanced oxidation processes (AOPs), is applied to reduce the ozone consumption and to increase the Chemical Oxygen Demand (COD) ...
Reducing chlorinated organics, AOX, in the bleachery effluents of a Turkish pulp and paper plant
Yetiş, Ülkü; Gokcay, CF (1996-01-01)
The possibility for reducing the chlorinated organic compounds in the bleacheary effluents of the Turkish pulp and paper industry has been studied. Within the experimental work of this study, three different chlorine dioxide substitutions and three different total chlorine application rates were examined and nine experiments were performed. The AOX formation has been shown to be proportional to the amount of molecular chlorine consumed during delignification, regardless of whether it is from chlorine or chl...
