Estudo e desenvolvimento de sistema desaerador de água para equipamentos de ensaios laboratoriais de geotecnia.

Abstract

The present work addresses the obtaining of anoxic water, focusing on establishing the necessary criteria for the development of a custom deaerator for the company Owntec. The objective is to research and test efficient methods of water deaeration, establishing suitable parameters through laboratory tests. The research took place throughout 2023 at Owntec - Engineering Solutions, located within the Tecnounisc - Scientific and Technological Park and Itunisc - UNISC Technological Incubator, located on the UNISC Campus, in Santa Cruz do Sul – RS, which specializes in the development of solutions for Geotechnics, including Static Triaxial equipment. In this study, different methods were explored, involving an analysis of water deaeration models available in the market, considering both laboratory application and previously proposed methods. To achieve the objectives, the methodology employed included applied research for the study and comparison of different water deaeration methods, and the analysis of results obtained through experimental tests. The results indicated that specific methods, such as ultrasound + vacuum, showed an efficacy of 70.41% in reducing dissolved oxygen, compared to other commercially available methods such as agitator + vacuum, which presented 36.43% efficacy.
