Effect of carbon to nitrogen ratio (C/N) on the sludge extracellular polymer composition is studied in synthetically fed semi-continuous reactors with 8 days of sludge age. Results show that C/N ratio influences the relative distribution of polymer carbohydrate and protein. At low C/N ratio of 5, polymer extracts have high protein and low carbohydrate content. As the C/N ratio is increased to 17.5 and then to 40, carbohydrate concentration increases sharply and protein concentration decreases.

Effect of carbon to nitrogen ratio on the physical and chemical properties of activated sludge Durmaz, B; Sanin, Faika Dilek (2003-11-01) The effect of carbon to nitrogen ratio (C/N) of the feed on the physical and surface chemical properties of activated sludge is investigated. Semi-continuous reactors with 2 liters volume were operated at a mean cell residence time of 8 days. These mixed culture reactors were operated at 3 different carbon to nitrogen ratio. The operation of conventional activated sludge plants treating municipal wastewater is represented with reactors having a C/N ratio of 21 (in terms of the ratio of COD to TKN). Carbon a...
Effect of EDTA on activated sludge properties Sanin, Faika Dilek (2001-02-01) Bacterial extracellular polymers have been found to be important in bioflocculation of activated sludge. In this study ethylene diamine tetra acetic acid (EDTA) method of extracting bacterial extracellular polymers is examined. Following extractions, it is observed that EDTA extracted significant amounts of biopolymers. However, the chemical treatment causes serious changes in sludge properties. Sludge particle size is reduced from 21 mum to 14.6 mum, filtration properties of sludge deteriorates, indicated ...
Effect of chromium(VI) on the biomass yield of activated sludge Yetiş, Ülkü; Gokcay, CF (1999-07-15) Effect of 1-25 mg/l of influent Cr(VI) concentrations on true biomass yield (Y-t) and decay coefficient (k(d)) of activated sludge units was investigated in this study. To this purpose, completely mixed, once-through laboratory scale activated sludge units with acclimated cultures were operated. After obtaining dilute-out curves for each Cr(VI) concentration, the values of Y-t and k(d) were determined. The results revealed that presence of Cr(VI) caused stimulatory effects on biomass yield and maintenance u...
Effect of rigid rod molecular structures on the properties of regenerated and virgin poly(ethylene terephtalate) Duru, C. Zeynep; Bayramlı, Erdal; Department of Polymer Science and Technology (2004) In recent years,the recycling of plastic waste incerased worldwide.The basic impetus for this increase is the public awereness regarding polltuion of the environment.Many different types of recycling processes are being used to reduce the use of raw materials and to reduce energy consumption.PET recycling is one of the most important recycling processes.addition of thermotropic liquid crystalline polymers has also become wide-spread in recent years to increase their mechanical properties and other selected ...
Effect of calcium carbonate addition on carbothermic formation of hexagonal boron nitride ÇAMURLU, HASAN ERDEM; SEVİNÇ, NACİ; Topkaya, Yavuz Ali (Elsevier BV, 2008-01-01) Effect of CaCO3 on formation of hexagonal boron nitride (h-BN) was investigated by holding CaCO3 free and CaCO3 added activated carbon-boric oxide mixtures under nitrogen atmosphere at 1500 degrees C for 30-120 min. Amount of CaCO3 addition was varied in the range of 0-50 wt.% of the initial mixture. Products were characterized by powder X-ray diffractometry, FT-IR analysis, quantitative chemical analysis, scanning electron microscopy and BET specific surface area analysis. It was observed that calcium carb...
