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. Optimization of the extraction of phenolic compounds from olive pomace using response surface methodology
ABSTRACT Extraction of olive oil gives rise to large quantities of pomace and liquid effluents, since on average only 21% of the weight of the olive corresponds to oil, the remaining 79% consists of water, bark, pulp and stone. With the intention to make available new forms of use of this residue, this research was proposed, with aimed to optimize the extrac

3. ESTIMATION OF PARAMETERS AND STATES USING A BAYESIAN PARTICLE FILTER FOR THE SULFATE ION ADSORPTION PROCESS IN A FIXED BED COLUMN
Abstract Ensuring that industrial effluents meet quality standards to be released into water bodies is still one of the major environmental concerns. Liquid phase adsoption in fixed bed collumns is one of the most known treatments. Measurements are needed to monitor the process. However, as they are often corrupted by noise from the measuring equipment, perf

4. 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

5. 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

6. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO PARA DETERMINAÇÃO DE BISFENOL A E ETINILESTRADIOL EM AGUAPÉ E MINI-PAPIRO PROVENIENTES DE WETLANDS CONSTRUÍDAS
Bisphenol A and ethinylestradiol, both considered as endocrine disruptors, have been found in surface water and effluents from municipal wastewater supply and can cause adverse health effects on wildlife species and in human beings at extremely low level. In order to remove these compounds from wastewater, constructed wetlands has been used since it proved t

9. 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

10. 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)

11. 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
