“…As a consequence, 70 % of COD degradation can be achieved. Around 2.67 times higher OLR was achieved in two laboratory aerobic SBRs treated with a mixed landfi ll and dairy effl uent than in traditional SBR processes (71). The best BOD 5 removal mode was reached at OLR, expressed as BOD 5 , of 0.8 kg/(m 3 ·day) per a 10--day HRT.…”

“…However, mechanical treatment had to be applied fi rst. Another study shows the aerobic SBR as an excellent example of the combination of activated sludge granulation with dairy effl uent treatment (71). Granulation stability is limited by nutrient concentration in the wastewater, while effl uent quality depends on the need for preliminary sludge sett ling, usually 0.25-0.5 HRT.…”

SummaryThe milk processing industry is one of the world's staple industries, thus the treatment possibilities of dairy effl uents have been att racting more and more att ention. The purpose of the paper is to review contemporary research on dairy wastewater. The origin, categories, as well as liquid by-products and general indicators of real dairy wastewater are described. Diff erent procedures applied for dairy wastewater management are summarised. Att ention is focused on in-factory treatment technologies with the emphasis on biological processes. Aerobic and anaerobic methods with both their advantages and disadvantages are discussed in detail. Consecutive anaerobic and aerobic systems are analysed, too. Finally, future research niches are identifi ed.

“…No obstante, se han adelantado investigaciones importantes sobre tratamiento de aguas residuales para un gran espectro de efluentes, que van desde la aguas residuales domésticas hasta diferentes efluentes industriales, para la eliminación de materia orgánica, N y P. Los SBR también han demostrado buenos resultados en el tratamiento de diferentes tipos de lixiviados provenientes de rellenos sanitarios en diversas partes del mundo [51][52][53][54][55][56]40].…”

<p>El interés en eliminar contaminantes de las aguas residuales se ha incrementado en los últimos años. Existe una constante búsqueda de nuevos y mejores diseños que permitan la implementación de sistemas de tratamiento confiables, de bajo costo y que ofrezcan mejores resultados. Esta tarea ha sido realmente un reto, debido a la generación de múltiples tipos de vertimientos líquidos, con diferentes características y composición y, en particular, al cumplimiento de estrictas y diferentes regulaciones que en los distintos países se establecen en materia de control ambiental. La investigación en el área de la ingeniería y las ciencias ambientales ha permitido el desarrollo de la tecnología de reactores discontinuos secuenciales (SBR, por sus siglas en inglés), como una variación del proceso de lodos activados convencional para la eliminación de materia orgánica y de nutrientes de las aguas residuales. El presente artículo de revisión describe la importancia de este tipo de sistemas, teniendo en cuenta las generalidades del tratamiento, la descripción técnica del sistema, los parámetros de operación más importantes, el mecanismo biológico del proceso de eliminación y las diferentes modificaciones al diseño original. Finalmente, se encontró que este tipo de sistema es de gran utilidad y ofrece muchas ventajas en la eliminación de nutrientes y materia orgánica, en comparación con los sistemas convencionales de tratamiento, además de que se puede aplicar para el tratamiento de gran cantidad y diversidad de aguas residuales tanto domésticas como industriales.</p>

“…Data on qualitative and quantitative characteristics of raw dairy sewage are relatively well-documented [4][5][6][7][8][9][10][11][12][13][14][15][16], but at the same time there are serious gaps in relation to the municipal sewage with a specific share of industrial (dairy) wastewater. For this reason, it is impossible to compare the results with literature data.…”

“…Quantity of dairy sewage is characterized by high seasonal variations (20% increase in spring and summer). Additional oscillations relate to the daily and hourly shift work dependent on the size, production profile, and shifts at milk processing plant [4][5][6][7][8][9][10][11][12]. Biological treatment of dairy wastewater is high-efficient due to the significant share of easily biodegradable substances [13][14][15][16].…”

Abstract. Municipal WWTP often receive the industrial wastewater, including dairy sewage. The problem of sewage treatment from this sector of economy is not completely solved, especially in plants of medium and small milk processing capacity. The aim of the study was to determine the rate of change in organic compounds and nutrients in municipal wastewater with the participation of dairy products during the processing phases of SBR-type reactor in a technical scale. The study was conducted in WWTP in Sokolka. Rate of changes in the concentrations of organic compounds, nitrogen and phosphorus in wastewater during the processing phases of SBR reactor was determined. Presence of dairy sewage (13% volume participation) affected the decrease in the rate of changes in organic compounds concentrations defined as BOD 5 during all processing phases of SBR reactor. Significant influence of dairy sewage on rates of change in nitrogen and phosphorus compounds concentrations during filling, aeration, stirring, sedimentation and decantation phases, was found.
