Effects of nickel, chromium and substrate concentration on the microbial growth of acclimatized and unacclimatized microbes of sewage origin were studied in batch cultures at a constant temperature of 25 °C, at pH 7.0. A synthetic medium supplemented with Ni(II) (5 and 10 mgl‐1) or Cr(VI) (1 and 50 mgl‐1) or with their combinations and at various feed concentrations (650, 975, 1300 mgl‐1) was employed to investigate the effects on the specific growth rate (μm) of the microbial culture. The experimental results were statistically analysed by using multiple regression techniques

The effect of seed sludge type on aerobic granulation via anoxic-aerobic operation Ersan, Yusuf Cagatay; Bayramoğlu, Tuba Hande (Informa UK Limited, 2014-12-01) The effects of two seed sludge types, namely conventional activated sludge (CAS) and membrane bioreactor sludge (MBS), on aerobic granulation were investigated. The treatment performances of the reactors were monitored during and after the granulation. Operational period of 37 days was described in three phases; Phase 1 corresponds to Days 1-10, Phase 2 (overloading conditions) to Days 11-27 and Phase 3 (recovery) to Days 28-37. Aerobic granules of 0.56 +/- 0.23 to 2.48 +/- 1.28mm were successfully develope...
EFFECT OF TEMPERATURE, PH AND DO CONCENTRATION ON FILTERABILITY AND COMPRESSIBILITY OF ACTIVATED-SLUDGE SURUCU, G; Sanin, Faika Dilek (Elsevier BV, 1989-11-01) This study investigates the effect of aeration basin temperature, pH and dissolved oxygen (DO) concentration on filterability and compressibility characteristics of activated sludge. Laboratory-scale semi-continuous reactors, fed with synthetic wastewater were used. Effects of temperatures of 15, 20, 25, 30, 35°C; pH values of 5.7, 7.2, 8.2, 9.0 and DO concentrations of 0.5, 1.0, 1.5, 2.0, 5.0 ml/l were studied by keeping all the other parameters constant in each case. Results indicated that as the operatin...
Removal and recovery of nutrients as struvite from anaerobic digestion residues of poultry manure Yılmazel Tokel, Yasemin Dilşad (Informa UK Limited, 2011-01-01) The removal and the recovery of nutrients, namely nitrogen (N) and phosphorus (P) from anaerobically digested and solid-liquid separated manure effluents via struvite precipitation were investigated. Both the liquid and the solid phases of the poultry manure digester effluent were subjected to struvite precipitation experiments. The Mg:N:P molar ratio of 1:1:1 in the liquid phase resulted in an average NH4-N removal efficiency of 86.4%, which increased to 97.4% by adjusting the Mg:N:P ratio to 1.5:1:1. The ...
Control of trichloroethylene emissions from sparging systems by horizontal bio- and chemo-barriers Tezel, U; Demirer, Göksel Niyazi; Uludag-Demirer, S (Informa UK Limited, 2005-02-01) The scope of this study was to develop a continuous system to clean-up a trichloroethylene (TCE) contaminated gas stream, where biotic and abiotic removal mechanisms are undertaken sequentially simulating the horizontal bio- and chemo-barriers proposed for the in-situ remediation of the contaminated sites. The bio- and chemo-barriers were simulated by using glass columns packed with granular anaerobic mixed culture and Fe(0) filings, respectively. The effect of gas residence time, which is adjusted by the g...
Effect of digester F/M ratio on gas production and sludge minimization of ultrasonically treated sludge Koksoy, Gozde T.; Sanin, Faika Dilek (IWA Publishing, 2010-01-01) Sludge pretreatment by mechanical, chemical or thermal methods before anaerobic digestion has been applied to increase the digestability of excess sludge Pretreatment processes rely on their ability to disrupt cell membranes and to release organic materials from the cells into the aqueous phase Pretreatment by mechanical disintegration has grown rapidly in recent years in parallel with the advances in technology Ultrasonic sludge disintegration one of the most commonly used mechanical pretreatment methods- ...
