Accumulation of arsenic in plants from arsenic contaminated irrigation water
Ozturk, Mustafa; Aslan, Sukru; Demirbas, Ahmet (PAMUKKALE UNIV, 2017)Arsenic occurs naturally in the earth's surface and is widely distributed in the environment. Arsenic is commonly encountered in groundwater in different parts of the world due to natural processes as well as from anthropogenic ... -
Ammonium oxidation via nitrite accumulation under limited oxygen concentration in sequencing batch reactors
Aslan, Sukru; Miller, Lindsey; Dahab, Mohamed (ELSEVIER SCI LTD, 2009)In this study, the effects of sludge retention time (SRT) on NH(4)-N oxidation and NO(x)-N accumulation in the nitritation reactors were studied. The gradually decrease of SRT also caused long reaction time to achieve 99% ... -
ASSESSMENT OF THE ADSORPTION KINETICS, EQUILIBRIUM AND THERMODYNAMICS FOR THE POTENTIAL REMOVAL OF NI2+ FROM AQUEOUS SOLUTION USING WASTE EGGSHELL
Aslan, Sukru; Polat, Ayben; Topcu, Ugur Savas (VILNIUS GEDIMINAS TECH UNIV, 2015)In this study, Ni2+ sorption onto the waste eggshell was investigated under different operational conditions. Results indicated that the eggshell could be successfully used to remove Ni2+ ions from the water. Quick sorption ... -
Biological denitrification of drinking water in a slow sand filter
Aslan, Sukru; Cakici, Hatice (ELSEVIER SCIENCE BV, 2007)Biological removal of nitrate from drinking water was studied in a slow sand filter. Optimum carbon to nitrogen ratio (C/N) was found to be 1.8 when using acetic acid in batch tests. The filtration rates impact on NO3-N ... -
Biological nitrate removal in a laboratory-scale slow sand filter
Aslan, Sukru (WATER RESEARCH COMMISSION, 2008)This research evaluated removal of nitrates from drinking waters in a slow sand filter (SSF). Batch experiments were performed to determine optimum carbon to NO3-N (C/N) ratio for the filtration experiments. The filter ... -
Biosorption of Cu2+ and Ni2+ ions from aqueous solutions using waste dried activated sludge biomass
Aslan, Sukru; Yildiz, Sayiter; Ozturk, Mustafa (DE GRUYTER POLAND SP ZOO, 2018)Adsorption of Cu(II) and Ni(II) ions onto the waste powdered activated sludge biomass (PWB), which was obtained from the biological wastewater treatment plant, was investigated in this experimental study. The effects of ... -
Cancer risk assessment in drinking water of Izmir, Turkey
Aslan, Sukru; Turkman, Aysen (SPRINGER, 2007)In this study, the occurrence of trihalomethanes (THMs) of the tap water in Izmir City was investigated and the lifetime cancer risk of THMs through oral ingestion, dermal absorption, and inhalation exposure were estimated. ... -
The effect of petrochemical industry wastewater composition on the activated sludge microflora
Turkman, Aysen; Aslan, Sukru; Ozdurakoglu, Nilufer (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2006)In this study, the effect of wastewater composition on the activated sludge microflora has been evaluated. Wastewater samples from the aeration tank of a petrochemical industry wastewater treatment plant were taken and ... -
Individual and combined effects of nickel and copper on nitrification organisms
Aslan, Sukru; Sozudogru, Onur (ELSEVIER SCIENCE BV, 2017)Individual and combined effects of Ni2+ and Cu2+ concentrations on the nitrification process were investigated in a submerged biofilter. The activity of nitrification organisms was inhibited by high concentrations of Cu2+. ... -
Influence of Operational Parameters and Low Nickel Concentrations on Partial Nitrification in a Submerged Biofilter
Aslan, Sukru; Gurbuz, Burhanettin (HUMANA PRESS INC, 2011)The effect of Ni(2+) concentrations on ammonium oxidation was studied in a batch and partial bionitrification reactor (PBNR). The nitrification rates up to the concentration of 0.1 mg Ni(2+)/l were close to those without ... -
Influence of salinity on partial nitrification in a submerged biofilter
Aslan, Sukru; Simsek, Erdal (ELSEVIER SCI LTD, 2012)Partial nitrification under various concentrations of NaCl (0-40 g/l) at a constant operational condition was investigated in a submerged biofilter reactor. The highest NO2-N/NOx-N ratio (0.76) was achieved at the NLR of ... -
Nitritation and denitritation of ammonium-rich wastewater using fluidized-bed biofilm reactors
Aslan, Sukru; Dahab, Mohamed (ELSEVIER SCIENCE BV, 2008)Fluidized-bed biofilm nitritation and denitritation reactors (FBBNR and FBBDR) were operated to eliminate the high concentrations of nitrogen by nitritation and denitritation process. The dissolved oxygen (DO) concentration ... -
