Effect of carbon to nitrogen ratio on the composition of microbial extracellular polymers in activated sludge
Durmaz, B; Sanin, Faika Dilek (2001-01-01)
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 carbonate alkalinity on flotation behavior of quartz
Sayilgan, A; Arol, Ali İhsan (Elsevier BV, 2004-11-19)
Alkalinity is defined as the capacity of a water to neutralize strong acids. In natural waters, this capacity is generally attributable to bases such as HCO3-, CO32 and OH- as well as to species often present in small concentrations such as silicates, borates, ammonia, phosphates and organic bases. Carbonate alkalinity of process waters in mineral processing may change as a result of the seasonal climatic changes, the fresh water source and the amount of recycled process water. Any mineral processing plants...
Effect of alkalinity on flotation behavior of quartz
Sayılgan, Aslı Halime; Arol, Ali İhsan; Department of Mining Engineering (2003)
Carbonates are always present in natural waters, thus in the process waters in flotation. When CO2 dissolves in water it forms a weak acid. This acid and its salts in solution constitutes the carbonic system. The pH of natural waters on land is controlled mainly by this system. Alkalinity is the capacity of a water to neutralize strong acids. In natural waters, this capacity is attributable to bases such as HCO3, CO3" and OH" as well as to species often present in small concentrations such as silicates, bor...
Effect of Feed Composition on the Gas Separation Performance of Binary and Ternary Mixed Matrix Membranes
Sen, Deger; Yılmaz, Levent; Kalıpçılar, Halil (Informa UK Limited, 2013-03-01)
Binary and ternary component mixed matrix membranes comprised of zeolite 4A and p-nitroaniline (pNA) in the polycarbonate (PC) matrix were prepared and appraised in gas separation. For comparison, homogenous membranes of PC and PC/pNA membranes were also investigated. The membranes were utilized to separate binary mixtures of CO2/CH4, H2/CH4, and CO2/N2. The effect of feed composition on the separation performance of membranes was investigated. Separation factors and ideal selectivities were similar for the...
