Removal of Trace Amounts of Copper from Concentrated Hydrochloric Acid Solutions

Pickling process is recognized as one of the strongest acid consuming processes in the steel industry. A pickling solution that contains hydrochloric acid (HCl) is used for the metal surface treatment of steel plants. The same acid can be used for a long period of time by means of a regeneration process, in which iron concentration of the acid is decreased to insignificant concentrations. However, regenerated pickling solutions contain copper, especially when scrap is used to produce steel. Furthermore, cop...

Removal of chlorinated organics from pulping effluents by activated sludge process
Ataberk, S; Gökçay, Celal Ferdi (1997-03-01)
Combined effluents of a Kraft pulp mill using yearly plants were treated in a lab-scale activated sludge system. Average TOC and AOX removal efficiencies were 83% and 21% respectively. The effect of the operating solids retention time (SRT) on AOX removal was investigated and it was found that highest AOX removal (30%) occurs at longer SRT's. Mass balance on the system revealed that the principal AOX removal mechanism was metabolization at long SRT. About 90% of the AOX removed was metabolized. As SRT was l...
Removal of phenolic compounds from rubber-textile wastewaters by physico-chemical methods
Ozbelge, TA; Ozbelge, OH; Baskaya, SZ (Elsevier BV, 2002-09-01)
Removal of phenolic compounds from rubber-textile wastewaters (RTWWs) by physico-chemical process was investigated by using four different types of coagulants (Al-2(SO4)(3), Fe-2(SO4)(3), FeSO4, FeCl3) with or without lime (Ca(OH)(2)) addition, in jar-test experiments. The RTWWs of the present tire-cord fabric plant may contain seven different types of dipping solutions (DSs), which provide an adhesive property to the fabric. The optimum results were obtained by using 50% FeCl3 solution and lime at various ...
Removal of imidacloprid from wastewaters by ozonation and photo-ozonation
Sönmez, Büşra; Dilek, Filiz Bengü; Department of Environmental Engineering (2019)
The widespread occurrence of micropollutants in the receiving water bodies apparently shows that conventional wastewater treatment plants (WWTP) are not capable to remove these compounds. Imidacloprid (IMI), which is a specific pollutant and an insecticide, exceeded Environmental Quality Standards (EQS) value (0.14 µg/L, annual average) in several receiving water bodies of WWTPs in Yeşilırmak basin. With the aim of examining advanced treatment methods to meet EQS value and to achieve good surface water qual...
