Abstract: This paper reports the efficiency of the solvent-driven fractional crystallization (SDFC) process using ethanol, also known as antisolvent crystallization, in the treatment of a concentrated wastewater by reverse osmosis (RO). This experiment evaluated the effects of varying the volumetric mixing ratio of ethanol-to-RO concentrate, in conjunction with the incorporation of Ca(OH)2, on the efficiency of... More

Abstract: The capabilities of GIS for constructing a digital elevation model of a mountainous area and visualizing a spatial image of the terrain are given in this paper. Graphic, digital data and topographic maps, which are the main sources for GIS, are described. The methods of vectorization of isolines and the requirements for technical means of... More
