Abstract(s)
O presente trabalho resulta de um desafio proposto pela unidade de enchimento da Colep Portugal, em meio industrial, um setor que necessita de água para diversas utilizações, originando consideráveis quantidades de águas residuais, necessitando parte delas, de um tratamento prévio à descarga em coletor municipal, tratamento esse realizado na Estação de Tratamento de Águas Residuais Industriais (ETARI) da Colep. O foco do trabalho incidiu no mapeamento todos os fluxos gerados na empresa, incluindo dos que afluem à ETARI, através de amostragens que permitiram a sua caraterização, com base na qual foi decidida a sua gestão. Paralelamente, estudou-se a eficiência do processo de tratamento implementado na ETARI, baseado essencialmente num processo físico-químico. O acompanhamento do processo permitiu inferir várias oportunidades de melhoria, algumas delas já implementadas, outras serão implementadas a curto prazo. A segregação de fluxos proposta resultaria numa diminuição de cerca de 60% do volume afluente à ETARI, permitindo um melhor controlo do processo de tratamento e aumentando a sua eficiência.
The present work came from a challenge proposed by the Colep Portugal filling unit in an industrial environment, a sector that requires water for various uses, causing considerable amounts of wastewater, requiring some of them, a treatment prior to discharging into a municipal collector, treatment carried out at the Industrial Wastewater Treatment Plant (IWWTP) of Colep. The work focused on the mapping of all the flows generated in the company, including those that flow to the IWWTP, through samplings that allowed its characterization, based on which it was decided the flow management. At the same time, the efficiency of the treatment process implemented in the IWWTP, based essentially on a physical-chemical process, was studied. The monitoring of the process allowed to infer several opportunities for improvement, some of them already implemented, others will be implemented in the short term. The proposed segregation of fluxes would result in a decrease of about 60% in the volume affluent to the IWWTP, allowing a better control of the treatment process and increasing its efficiency
