Sources of adsorbable organic halogens (AOX) in sludge of Gaza.
Average concentrations of adsorbable organic halogens (AOX) in sludge from the Gaza Strip reached 600 mg kg(-1) which currently represents a major limiting factor for sludge application in agriculture. This study aims to identify the main sources of AOX in Gaza where the area is small with limited industrial activities. The results showed that the AOX in effluent sludge is formed mainly inside ...
متن کاملKinetics of AOX Formation in Chlorine Dioxide Bleaching of Bagasse Pulp
In this paper, a kinetic model of the first chlorine dioxide bleaching stage (D0) in an elemental chlorine-free (ECF) bleaching sequence is presented for bagasse pulps. The model is based on the rate of adsorbable organic halogen (AOX) formation. The effects of the chlorine dioxide dosage, the sulfuric acid dosage, and the reaction temperature on the AOX content of wastewater are examined. The ...
متن کاملAdsorbable organic halides ( AOX ) , AOX formation potential , and PCDDs / DFs in landfill leachate and their removal in water treatment processes
Adsorbable organic halides (AOX) and AOX formation potential (AOXFP) were investigated in 46 landfill lea-chates as potentially toxic parameters. AOX in landfill leachate was within the range <10–2200 mg Cl/l, and AOXFP was within 51–15 000 mg Cl/l. AOX and AOXFP correlated with chemical oxygen demand (COD).AOX discharge from closed landfills was generally lower than that from operating landfil...
متن کاملDegradation of organochlorine compounds in spent sulfite bleach plant effluents by actinomycetes.
Actinomycetes isolated from different soil samples were tested for their abilities to utilize spent sulfite bleach effluents from a paper mill. Degradation and dechlorination of the chlorinated compounds in the effluents of the first two bleaching stages, i.e., chlorination stage [(C + D)red.] and alkaline extraction stage (E1O), were monitored by determining total organic carbon (TOC) and acti...
متن کاملInfluence of Surfactants on the Removal of AOX Using Micellar- Enhanced Ultrafiltration
This paper presents the development of a model for evaluating adsorbable organic halogens’ (AOX) removal efficiency during wastewater treatment by using the micellar-enhanced ultrafiltration (MEUF) technique. Surfactants can form larger aggregates (micelles) were prepared into which AOXs dissolve and are then retained by the membrane. Synthetic wastewater samples containing certain concentratio...
