Effluent characterization and waterbody monitoring from an olive pomace oil extractor industry
| Resumo: | The environmental impact is a relevant aspect of the production of Olive oil, it is a relevant Portuguese economic sector, with job creation, maintaining rural populations, however the by-product, olive mill wastewater and olive pomace, became one important focus to the circular economy, one of the many valorizations economic viable is the olive pomace oil. The olive pomace oil industry is responsible for a secondary oil extraction based in mixture organic solvent with the olive pomace from the olive oil production. This process produces a wastewater what was physicochemical characterized -COD, BOD, TS, TSS, FOG, organic nitrogen, ammonia and phosphorus content, pH and conductivity, phenolic compounds and aromaticity, and Zahn-Wellens biodegradation test - in this study as the first step to a wastewater design for the factory. The main objective is to be able to return the treated wastewater in the river next to the factory with the required quality by the Portuguese legislation. The river water was also characterized in four different points to evaluate the factory environmental impact, the results show no large variation in the analyzed parameters when compared with the current legislation.) |
