“…However, aerobic treatment has some major disadvantages, such as high power consumption, large amount of sludge production, high cost of sludge handling and so on. Considering the wastewater composition with high COD values (approximately 4000 mg/L), anaerobic treatment is a suitable method for the treatment of wastewaters from the potato-processing industry [5]. Anaerobic treatment, especially the thermophilic process, offers an attractive alternative for the treatment of high strength wastewater streams [6].…”

____________________________________________________________________________Resumo: Este trabalho trata da degradação do efluente de uma indústria de processamento de batatas da região de Itajubá (MG), que é um polo de batata processada. A escolha desse efluente baseia-se no fato de empresas da região estarem em busca de um destino final mais adequado para esse tipo de rejeito. Apesar de não tóxico, se este tipo de efluente não for tratado corretamente, pode contribuir para o desaparecimento de nascentes, aparecimento de odor desagradável nos rios e danos à fauna e à flora local. O presente estudo possui como finalidade avaliar se a ferrita de pilha é eficaz no tratamento de efluente de indústria de processamento de batatas. ) com presença e ausência de radiação solar em diferentes tempos de tratamentos do efluente de batata com valor de pH ajustado em 2,5. Obteve-se uma eficiência de aproximadamente 32% de mineralização dos compostos orgânicos do efluente durante os primeiros dez minutos, evidenciando a eficácia da ferrita como catalisador do processo, além de mudanças significativas na cor do efluente (deixando-o transparente) e eliminação do cheiro fétido. Além disso, as ferritas puderam ser recuperadas ao final do processo pela aplicação de um campo magnético, evitando dessa forma, a liberação de catalisador no efluente e permitindo o seu reuso.Palavras-chave: Processos Oxidativos Avançados.

The choice of this effluent is based on the fact that companies in the region are in search of a final destination more suitable for this type of waste which causes damage to fauna and flora. Although not toxic, if this type of effluent is not treated correctly it can contribute to the disappearance of springs, the appearance of unpleasant odors in the rivers and damage to the local fauna and flora. The present study has the purpose to evaluate if the battery ferrite is effective in the treatment of effluent of the potato processing industry. Therefore, different catalysts were used: Fe(NO 3 ) 3 .9H 2 O and Ferrite, different H 2 O 2 (15 and 30 mmol L -1 ) concentrations with and without solar radiation in different treatment times of the potato effluent with pH value adjusted in 2.5. Approximately 32% of mineralization of the effluent organic compounds were reached during the first ten minutes, demonstrating the effectiveness of ferrite as a catalyst in the process, as well as significant changes in the effluent color and elimination of the odor. In addition, the ferrites could be recovered at the end of the process by applying a magnetic field, thus avoiding the release of catalyst in the effluent and allowing its reuse.

“…Among three different peeling methods (abrasion peeling, steam peeling and lye peeling), lye peeling is the most popular peeling method used today. Therefore, lye peeling wastewater is the most troublesome potato waste due to very high pH (11-12), high organic content mostly in colloidal form (Hung et al, 2006). The wastewater flows from different potato processing industries were reported as 17 m 3 /ton potato processed (Hung et al, 2006), 5-8 m 3 /ton potato processed (Guttormsen & Carlson, 1969), 3,9 m 3 /ton potato processed (AustermanHoun & Seyfried, 1992) and 5,8 m 3 /ton potato processed (Cooley et al, 1964).…”

Several publications on the characteristics of wastewaters resulting from various types of potato processing plants are summarized in Table 4.…”
