1. Structural and biological properties of protein hydrolysates from seafood by-products: a review focused on fishery effluents
Abstract Enormous amounts of by-products and waste are generated during the processing of seafood, sometimes representing about 65% of the raw material employed. Seafood by-products (SB) include solid waste such as skin, head, viscera, trimmings, and bones; however, liquid wastes (effluents) derived from operations such as washing, thawing, cooking and the p

2. Leachate and vinasse used in a biological process combined with Fenton’s reaction: a green method for treatment of textile effluents
Abstract: The production of textiles generates a large amount of liquid residues considered to be environmentally problematic and which, if discarded without due treatment, may cause eutrophication of water sources, the intoxication of living beings, and the blocking of light penetration. Some methods have been applied for the treatment of this type of waste

3. Enrichment of Copper, Lead, and Tin by Mechanical Dry Processing of Obsolete Printed Circuit Board Residues
Waste printed circuit boards (WPCB) residues were mechanically processed to concentrate their metal content aiming to reduce costs of the subsequent recovery of copper, tin, and lead. A fully dry route was proposed to avoid the generation of liquid effluents that would require additional treatment. Firstly, 10.7% of the residue was segregated by magnetic sep

4. Procedimentos para análise e validação de atributos da qualidade da água
RESUMO O tratamento incorreto de efluentes líquidos, assim como o seu lançamento inadequado, caracterizam algumas das maiores problemáticas ambientais e pode contribuir para a deterioração dos ecossistemas aquáticos. Nesse contexto, a utilização de modelos de predição possibilita, especialmente no caso de volumes, a observação do comportamento do

5. Membranas de fibra oca de polietersulfona: efeito do líquido interno e da adição de argila
RESUMO As membranas poliméricas vêm sendo bastante utilizadas no processo de tratamento de efluentes em todo mundo, solucionando problemas médicos, sociais e ambientais. Sendo assim, membranas de fibra oca foram produzidas a partir da polietersulfona (PES), adicionando a argila Cloisite Na – CLNa e também inserindo o solvente N,N dimetilformamida (DMF)

6. REMOVAL OF BPA FROM LANDFILL LEACHATES USING FENTON-ADSORPTION PROCESS
The objective of this investigation was to identify and quantify the presence of Bisphenol-A (BPA) in raw and treated leachates with the Fenton-adsorption process. BPA is used as a monomer to produce epoxy resins and it is a compound classified as endocrine disruptor. For this reason, it is important to quantify its presence in effluents that will be dispose

9. Degradation of textile dyes by cyanobacteria
Abstract Dyes are recalcitrant compounds that resist conventional biological treatments. The degradation of three textile dyes (Indigo, RBBR and Sulphur Black), and the dye-containing liquid effluent and solid waste from the Municipal Treatment Station, Americana, São Paulo, Brazil, by the cyanobacteria Anabaena flos-aquae UTCC64, Phormidium autumnale UTEX1

10. Screening of freshwater fungi for decolorizing multiple synthetic dyes
Abstract The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability were assessed in a liquid system; they belonged to 9 di

12. Aproveitamento da glicerina proveniente da produção de biodiesel na obtenção de híbrido de caulinita para adsorção de Cr3+
The aim of this work was to contribute to the creation of new ways of treating wastewater contaminated with Cr3+, based on solid-liquid adsorption. An adsorbent material was prepared by functionalization of kaolinite with glycerin biodiesel by-product. This material was tested for adsorption performed using a batch method, and results showed that inclusion o
