“…On the other hand, Christopher et al (2016) reported an average concentration of chromium in wastewater of only 500 mgCr/dm 3 . The significant concentrations of chromium in wastewater and the high use of these compounds by up to 90% of all tanning facilities boil down to the fact that the tanning industry is considered one of the most polluting in the world and responsible for about 40% of global chromium pollution (Bień et al, 2017;Celary & Sobik-Szołtysek, 2014;Chmielowski, 2019).…”

This paper presents a tannery industry's water and wastewater management problem. Information has been collected on the volume of water demand and, consequently, wastewater generation in these plants. This made it possible to relate them to the values generated by one of the smaller tanning plants located in Poland. The concentration of the pollutants contained in this wastewater, mainly chromium, was also determined from the study. Management of wastewater is a financial nuisance for small plants. The need to conclude contracts with specialized treatment plants, storage and long-distance transport of sewage, also by the respective companies, generates considerable costs, which may be a limiting factor of the willingness to invest in production. Wort reuse reduces the cost of purchasing chromium as a bath ingredient, reduces the frequency of waste disposal and significantly reduces company costs.

“…With undisturbed course of the process, the ratio of alkalinity to VFA should not exceed 0.3 [20] whereas inhibition of the development of methanogens in the reaction chamber occurs when its value exceeds 0.8 [21]. In the first days of the experiment, the VFA/alkalinity ratio was very high: 0.7 (2 nd day) and 0.36 (6 th day).…”

Abstract. The examinations concerned determination of the treatment efficiency of wastewater form dairy industry using the system which combines methane fermentation with ultrafiltration process. The study attempted to determine the effect of HRT and OLR on the degree of biodegradation of contaminants contained in the sludge examined and on the quality and amount of biogas. The anaerobic process obtained a considerable degree of the removal of organic pollutants from raw wastewater designated as COD (73.8%), BOD (81.2%) and TOC (76%). The concentrations of COD and BOD were 1053 mg/dm 3 and 329 mg/dm 3 , respectively. The value of TOC reached a level of 288 mg/dm 3 . Generated biogas in the methane fermentation process of wastewater from dairy wastewater was characterized by high methane content (82 % vol.). In the final part of the experiment, the UF process was used in order to posttreating effluent from UASB reactor. During the UF process, COD, BOD and TOC parameters were removed at 72%, 63% and 67%, respectively.

“…Kavouras et al, (2015), comentam que as características dos agentes poluidores, em quantidade e qualidade, do curtume dependerão de diversos fatores, como tecnologias empregadas no processo fabril, perfil de produto produzido, opções de tratamento de efluentes empregadas e outras mais. Bień et al, (2017), cita ainda que diversas opções de tratamento destes agentes poluidores estão sendo combinadas para prover maior eficiência na redução da carga poluidora, e consequentemente os impactos no ambiente.…”

A Produção Mais Limpa (P+L) comporta-se como uma ferramenta útil para o desenvolvimento sustentável através da aplicação contínua de uma estratégia de cunho ambiental e preventiva integrada aos processos, produtos e/ou serviços, de modo a reduzir os riscos para os seres humanos e principalmente, para o meio ambiente. Assim, no ambiente industrial, diversos segmentos apresentam os mais variados níveis de impacto ambiental de acordo com aspectos particulares de cada processo. A indústria do couro é um exemplo de ramo industrial que emprega grande quantidade de insumos poluentes e geram alto risco ao meio. Portanto, este artigo visou apresentar as vantagens da utilização da P+L no processo produtivo de um curtume, por meio da identificação de oportunidades de melhoria em pontos críticos, evidenciando os possíveis ganhos econômicos e ambientais provenientes desta metodologia. Constatou-se que a aplicação da P+L é de fundamental importância para as indústrias, pois tem por objetivo a otimização da aquisição de matérias primas, água e energia elétrica, reduzindo as despesas operacionais, além de buscar soluções rentáveis para a redução da geração dos rejeitos. No caso específico dos curtumes, esta metodologia P+L é altamente indicada pelo fato de que são indústrias altamente consumidoras de água, energia elétrica, produtos químicos e enfrentam sérios problemas com a geração de efluentes.
