The most common problems in the fish processing industry relate to high water consumption and the generation of effluents with concentrated organic loads. Given that reuse can represent an alternative for sustainable development, this study sought to assess the potential for recycling effluents produced in a fish-processing plant. In order to do so, the final industrial effluent was analyzed using the American Public Health Association (APHA) standard effluent-analysis method (2005). In addition, the study assessed treatments which produce effluents meeting the requirements prescribed by different countries' regulations for reuse and recycling. The results found that effluents with smaller organic loads, such as those from health barriers and monoblock washing, can be treated in order to remove nutrients and solids so that they can be subsequently reused. For effluents produced by the washing and gutting cylinders, it is recommended that large fragments of solid waste be removed beforehand. Effluents can in this way attain a quality compatible with industrial reuse. This study further highlights the possibility of treating effluents so as comply with drinking water standards. This would potentially allow them to be used within the actual fish-processing procedure; in such a case, a revision of standards and measures for controlling use should be considered to prevent microbiological damage to products and risks to handlers and final consumers.Keywords: effluent treatment, fish processing, reuse, sustainability. Potencial de reuso de efluente de indústrias de processamento de pescado RESUMOOs problemas mais comuns em indústrias processadoras de pescado estão relacionados ao alto consumo de água e à geração de efluente contendo cargas orgânicas concentradas. Sendo o reuso uma alternativa para o desenvolvimento sustentável na indústria, este estudo teve como objetivo avaliar o potencial de reciclo de efluentes gerados em uma indústria processadora de pescado. Para isto, realizou-se a caracterização do efluente industrial final empregando métodos padrões para a análise de esgoto da American Public Health Association, APHA (2005).

Os resultados obtidos demonstraram que os efluentes com menores cargas orgânicas, como os da barreira sanitária e lavagem de monoblocos, podem ser submetidos a tratamentos que priorizem a remoção de nutrientes e sólidos para posterior reciclo. Para o efluente proveniente de etapas do cilindro de lavagem e da evisceração, recomenda-se previamente a remoção dos resíduos sólidos grosseiros, de maneira que o efluente quando submetido a tratamento possa alcançar qualidade para o reuso industrial. Destaca-se ainda a possibilidade de tratar esses efluentes de modo que atendam as caracterís...

“…During freeze drying, substances are not exposed to high temperatures; therefore the freeze-dried products preserve their initial nutritious characteristics, and return to their original shape and texture instantaneously achieving long shelf life (BARUFFALDI; OLIVEIRA, 1998;PEREDA et al, 2005). This technique was used by ; Ponsano, Paulino and Pinto (2008) ;Pinto (2011) andSanto (2011) to dry R. gelatinosus biomass produced in industrial wastewater. On the other hand, spray drying technique consists of maximizing heat transfer, and it can be used for any product with a liquid-like behavior (BARUFFALDI; OLIVEIRA, 1998).…”

The use of colorants in products of animal origin is justified by the improvement in the color of foods since this attribute is considered a quality criterion. These additives can be produced using industrial effluents as substrates and appropriate organisms, such as Rubrivivax gelatinosus. Oxycarotenoids represent a class of carotenes responsible for the pigmentation of animals and vegetables. R. gelatinosus grows in fish industry effluent with the resulting production of a bacterial biomass containing oxycarotenoids. The purpose of this study was to compare the use of two drying processes - spray and freeze drying - to obtain powder biomass in terms of the process parameters (yield, productivity, and product recovery) and the product characteristics (color, proximate composition, and oxycarotenoids). No difference was detected in the yield between these techniques, while productivity was higher using spray drying. Higher product recovery and moisture were achieved with freeze drying, while ash was higher with spray drying. The freeze dried biomass was redder, darker and less saturated than the spray dried biomass. No difference in oxycarotenoids was detected between the biomasses. Although it results in lower recovery rate, spray drying was faster and more productive, and it provided the same yield as freeze drying, which makes it the method of choice for obtaining R. gelatinosus biomass.

Significance and Impact of the Study: This study first reported that the purple nonsulfur bacteria could grow well and possess high quality using Stevia residue extractions as carbon source. Those results suggest that wastewater of Stevia residue can be a favourable substrate for microbial growth, which can further provide desired bioresources for the application of downstream industry. AbstractAs a consequence of the large-scale cultivation of Stevia plants, releases of plant residues, the byproduct after sweetener extraction, to the environment are inevitable. Stevia residue and its effluent after batching up contain large amounts of organic matters with small molecular weight, which therefore are a potential pollution source. Meanwhile, they are favourite substrates for microorganism growths. This investigation was aimed to utilize the simulated effluent of Stevia residue to enrich the representative purple nonsulfur bacterium (PNSB), Rhodopseudomonas palustris (Rps. palustris), which has important economic values. The growth profile and quality of Rps. palustris were characterized by spectrophotometry, compared to those grown in common PNSB mineral synthetic medium. Our results revealed that the simulated effluent of Stevia residue not only stimulated Rps. palustris growth to a greater extent, but also increased its physiologically active cytochrome concentrations and excreted indole-3-acetic acid (IAA) content. This variation in phenotype of Rps. palustris could result from the shift in its genotype, further revealed by the repetitive sequence-based PCR (rep-PCR) fingerprinting analysis. Our results showed that the effluent of Stevia residue was a promising substrate for microbial growth.
