heal.abstract	T his diploma thesis dealt with the characterization and treatment of the liquid waste generated during the biotransformation of pre - treated and pre - dried household bioliquids in ethanol in the standard ethanol production unit operating in the Unit of Enviro nmental Science and Technology. The modern way of life and consumption of goods inevitably creates a large surplus in the form of waste, especially in urban areas, which can no longer be deposited exclusively in landfills. Together with the lack of resour ces and recycling facilities in many regions of the world, the need to create a viable plan for the exploitation all this waste produced led initially to the countries with the most developed economies in adopting environmental policies and legislation on waste exploitation through an organized collection, processing and disposal program . Biofuel production from bio - waste has given rise to a keen interest in modern industries as it is a cheaper choice than compatible oil used in most of the energy needs of a society such as heating and transport. The main liquid biofuel is ethanol, which is produced organically by fermentation of sugars derived from various sources. In the process of bioconversion of ethanol from household pre - treated waste, other liquid w astes are produced. A sample mixture was collected after the fermentation process. It was divided into 3 new 240 ml samples. Vacuum distillation of the sample was followed to collect ethanol. Subsequently, the remaining waste was led to the centrifuge to s eparate the solid and liquid phases. A series of treatments and analyzes were performed in the liquid waste to determine significant sizes. The first set of analyzes was carried out to identify all types of solids present in the liquid waste, such as tota l and volatile solids, and the corresponding suspended solids. The second series of measurements concerned analyzes made using the NOVA 60 photometric instrument, such as the determination of nitrate, nitrite, sulfate and phosphate, chemical oxygen demand (COD) and ammoniacal nitrogen. The third set of measurements concerned the calculation of total organic carbon (TOC) through the measurements of total carbon (TC) and inorganic carbon (IC), and total nitrogen (TN) using Total Organic Carbon Analyzer (TOC - V). The last measurement concerned the determination of Biochemical Oxygen Demand (BOD) for the first 5 days, as well as the calculation of the fats and oils present in the liquid waste. The total assay procedure was repeated for all 3 samples. From the results of the experimental measurements it was revealed that there is an agent leading to the concentration of the sample. For this reason, it was proposed to determine the amount of pectin, volatile fatty acids (VFA) and lignin to further evaluate the wa ste. Still, the way of using waste through the anaerobic digestion process could be achieved. Finally, although ethanol is not the subject of a study of the present diploma, the time and amount of distilled ethanol collected could provide more information to be used to optimize the production process	en
