1. PHYTOREMEDIATION OF FLUORIDE-CONTAMINATED WATER BY Landoltia punctata
ABSTRACT Fluorine is released into the water environment naturally or by anthropogenic activities. Fluorine promotes health benefits at low concentrations, but it promotes adverse effects ranging from fluorosis to carcinogenic problems at high concentrations. Although fluorine removal from environment can occur through processes such as adsorption, reverse o

2. CURRENT-VOLTAGE CURVES FOR TREATING EFFLUENT CONTAINING HEDP: DETERMINATION OF THE LIMITING CURRENT
Abstract Membrane separation techniques have been explored for treating industrial effluents to allow water reuse and component recovery. In an electrodialysis system, concentration polarization causes undesirable alterations in the ionic transportation mechanism. The graphic construction of the current voltage curve is proposed for establishing the value of

3. Avaliação do processo de eletrodiálise reversa no tratamento de efluentes de refinaria de petróleo
Este trabalho teve como objetivo avaliar a aplicação da eletrodiálise reversa no tratamento de efluente final de refinaria para reuso em sistema de resfriamento. O estudo foi conduzido nas instalações da Refinaria Gabriel Passos (REGAP)- MG, com efluente real, proveniente da saída da Estação de Tratamento de Despejos Industriais (E.T.D.I.), e utiliza

4. Modeling electrodialysis and a photochemical process for their integration in saline wastewater treatment
Oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this study, wastewater desalination by electrodialysis (ED) associated with an advanced oxidation process (photo-Fenton) was applied to an aqueous NaCl solution

5. Recovery and reuse of hexavalent chromium from aqueous solutions by a hybrid technique of electrodialysis and ion exchange
The chrome plating industry is one of the highly polluting industries whose effluent mainly consists of chromium(VI). This compound is highly toxic to aquatic life and human health. The rinse water constituents reflect the chrome plating bath characteristics; generally dead tank wash water contains about 1% of the plating bath concentration. Other metals and

6. Montagem e caracterização de unidade de eletrodiálise em escala de laboratório para tratamento de soluções salinas. / Assembly and characterization of unit electrodialysis in laboratory scale for treatment of saline solutions.
A escassez de água nos grandes centros urbanos deve se agravar nos próximos anos. Novas fontes de água são necessárias para suprir a demanda. Nas cidades não há disponibilidade de terrenos para construção de estações de tratamento de águas e esgotos convencionais. Por isso, são necessários novos processos de tratamento. Processos de separação

7. Integração dos processos de eletrodiálise e de degradação fotoquímica para o tratamento de efluentes salinos contendo fenol. / Integration of electrodialysis and photochemical degradation process for the treatment of a saline wastewater containing phenol.
Chemical oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this work, a coupled process is studied including a desalination step by electrodialysis (ED) associated with an advanced oxidation process (photo-Fent
