Several forms are employed for the treatment of these effluents, among which dissolved air flotation preceded by coagulation and flocculation, in order to remove suspended solids and colloidal material. The aim of this work was to study the coagulation associated with flotation in turbidity removal, as a form of treatment of effluent from a central laboratory of physical-chemical, serological and microbiological analyzes. The use of three different types of coagulants, each associated to a flocculant, was analyzed and three different treatments were used. The objective was to find the optimization conditions and obtain a model of turbidity removal. For the tests, bench-scale laboratory equipment was used in order to find the dosages of coagulants and flocculants, as well as the pH of the coagulation, which would best favor the efficiency of the coagulation / flocculation / flotation treatment.

This planning was done in order to support the Central Rotational Composite Design (DCCR), performed with the same three factors. As results of the three treatments, it was verified that the treatment with Aluminum Polychloride and Cationic Polymer, as well as the treatment with Novfloc and Polfloc presented satisfactory averages in turbidity removal (69.94% and 65.54%, respectively) while the treatment with Aluminum Sulfate and Anionic Polymer obtained an average efficiency of 40.76%. From the tests, performed by the DCCR methodology, surface graphs were obtained showing the optimization regions, as well as three statistically valid mathematical models for the turbidity removal.

Os efluentes líquidos gerados nas atividades industriais apresentam em sua constituição elementos que, se não removidos, podem causar contaminação e danos no ambiente onde estes forem lançados. Diversas formas são empregadas para o tratamento destes efluentes, dentre as quais a flotação a ar dissolvido precedida pela coagulação e floculação, com a finalidade de remover sólidos em suspensão e material coloidal. Assim, este trabalho teve por finalidade estudar a coagulação associada a flotação na remoção de turbidez, como forma de tratamento do efluente de um laboratório central de analises físico-químicas, sorológicas e microbiológicas. Analisou-se o emprego de três diferentes tipos de coagulantes, cada um deles associado à um floculante, compondo-se assim três tratamentos distintos. Objetivou-se encontrar as condições de otimização e obter um modelo de remoção de turbidez. Para os ensaios, utilizou-se um equipamento de laboratório em escala de bancada afim de encontrar as dosagens de coagulantes e floculantes, bem como do pH de coagulação, que melhor favorecesse a eficiência do tratamento por coagulação/floculação/flotação. Realizou-se ensaios preliminares e um planejamento inicial fatorial 2³, com três fatores: concentração de coagulante, a concentração de floculante e pH do efluente. Este planejamento foi efetuado de modo a oferecer suporte para o Delineamento Composto Central Rotacional (DCCR), realizado com os mesmos três fatores. Como resultados dos três tratamentos, verificou-se que o tratamento com Policloreto de Alumínio e Polímero Catiônico, assim como o tratamento com Novfloc e Polfloc, apresentaram médias satisfatórias na remoção de turbidez (69,94% e 65,54%, respectivamente), enquanto o tratamento com Sulfato de Alumínio e Polímero Aniônico obteve eficiência média de 40,76%. A partir dos ensaios, realizados pela metodologia do DCCR, obteve-se gráficos de superfície demonstrando as regiões de otimização, bem como gerou-se três modelos matemáticos válidos estatisticamente para a remoção de turbidez. Demonstrou-se com este trabalho a possibilidade de empregar a flotação para o tratamento de efluente de laboratório, bem como da viabilidade técnica e ambiental de utilizar o coagulante orgânico Novfloc e o polímero orgânico Polfloc. 2020-11-16T13:18:37Z 2020-11-16T13:18:37Z 2017-11-30 bachelorThesis PETRY, Jean Carlos.

The liquid effluents generated in the industrial activities present in its constitution elements that, if not removed, can cause contamination and damages in the environment where they are launched. Several forms are employed for the treatment of these effluents, among which dissolved air flotation preceded by coagulation and flocculation, in order to remove suspended solids and colloidal material. The aim of this work was to study the coagulation associated with flotation in turbidity removal, as a form of treatment of effluent from a central laboratory of physical-chemical, serological and microbiological analyzes. The use of three different types of coagulants, each associated to a flocculant, was analyzed and three different treatments were used. The objective was to find the optimization conditions and obtain a model of turbidity removal. For the tests, bench-scale laboratory equipment was used in order to find the dosages of coagulants and flocculants, as well as the pH of the coagulation, which would best favor the efficiency of the coagulation / flocculation / flotation treatment.
