Use of clinoptilolite for odour removal from restaurant emissions
Atımtay, Aysel (2004-11-19)
Clinoptilolite is well suited for adsorption applications due to its large amount of pore space, high resistance to extreme temperatures, chemically neutral basic structure and also its availability and low cost. In this project the relationship between odorant concentrations in the inner atmosphere of two restaurants were studied with respect to time by using a filter which has the clinoptilolite as packing material. "Olfactometer TO7" was used for determination of odorant concentrations. Results of the ex...
Use of calcium alginate as a coagulant in water treatment
Çoruh, Hale Aylin; Sanin, Faika Dilek; Department of Environmental Engineering (2005)
Coagulation and flocculation processes are important parts of water and wastewater treatment. Coagulation or destabilization of colloidal suspensions results in aggregation of colloidal particles by physical and chemical processes. Flocculation results in the formation of larger and settleable structures by bridging. Alginate, a polysaccharide obtained from marine brown algae, produces a gel structure when mixed with calcium ions, which is expected to be a potential coagulant in water treatment. This study ...

In this study, boric acid as a binder for briquetting some boron mine wastes, such as colemanite and ulexite fines and calcined products, which do not meet the market specifications with respect to particle size, were investigated. Effects of water and binder contents, applied pressure, and curing and drying conditions on the briquette quality were evaluated in terms of mechanical strength, water-proofing characteristics and wearing resistance. The best briquettes were obtained at 62.4 MPa pressure (cured a...
Use of waste pyrite as an alternative to gypsum for alkaline soil amelioration
TOZSİN, Gülşen; Arol, Ali İhsan; ÇAYCI, GÖKHAN (Informa UK Limited, 2015-05-04)
The reclamation of alkaline soils is of great interest especially in arid and semi-arid climatic regions of the world. The aim of this study was to investigate the application of pyrite from the waste materials of a copper concentration plant as an alternative to gypsum application for alkaline soil amelioration. The second aim was to assess heavy metal contamination. Waste pyrite (FeS2) obtained from a copper concentration plant and pure gypsum (CaSO4 center dot 2H(2)O) were added to soil within the column...
Use of calcium-alginate as a coagulant for low turbidity waters
Yüksel, Avni Mete; Sanin, Faika Dilek; Department of Environmental Engineering (2007)
This study aims to investigate the possibility of using calcium-alginate as a coagulant in low turbidity waters. Jar tests were initially performed with synthetically prepared turbid waters to investigate the effect of alginate and calcium concentrations, alginate’s molecular weight, rapid mixing time and speed (schedule), initial pH and alkalinity of synthetic water on turbidity removal efficiency of calcium-alginate system step by step. Alum as a coagulant was then used in jar tests conducted with synthet...
