The aim of this master thesis study was improvement of the required operational conditions for aerobic granulation in sequencing batch reactors (SBRs). In the first part of the study, membrane bioreactor sludge (MBS) and conventional activated sludge (CAS), were used to investigate the effect of suspended seed sludge type on granulation in SBRs. The MBS granules were found to be advantageous in terms of size, resistance to toxic effects, stability and recovery compared to CAS granules.

A lab-scale study of anoxic-aerobic digestion of waste activated sludge was performed, using 6 litre digesters, and operated in a semi - continuous (fed-once-a-day) manner with solids retention times (SRTs) of 20, 15 and 10 days and mixed-liquor temperatures of 20 °C and 10 °C. Raw sludge was obtained from a pilot-scale biological phosphorus removal facility operating at U.B.C. Fresh sludge was obtained daily and digested by three different digestion modes: anoxic-aerobic, aerobic with lime addition and aerobic. Two aerobic control digesters were run in parallel with the anoxic-aerobic digest

Streszczenie:

Biological nutrient removal (BNR) activated sludge systems (designed and operated with an additional function of biologically removing nitrogen and phosphorus) produce a waste activated sludge (WAS) that is rich in nitrogen (N) and phosphorus (P). When digested, this nitrogen and phosphorus are released, producing a dewatering liquor high in ammonia or nitrate and phosphate. Not only does this dewatering liquor need to be treated, but the phosphate also precipitates in the digester and surrounding pipework, resulting in loss of digester capacity and pipe blockages.

Solids handling can contribute to a significant portion of the operational costs of a wastewater treatment plant, contributing up to 50% of the total expenses in certain instances. Sludge dewatering and drying therefore become necessary not only from the operational perspective, but also from the economical viewpoint. The J-Vap process combines the above-mentioned processes, by pressure filtration of sludge followed by application of vacuum and heat. However, when cationic polymer conditioned sludge is dewatered in the J-Vap, the polymer is suspected to interact with the filter media at hig

Reaction water, a high-strength COD (chemical oxygen demand) petrochemical effluent, is generated during the Fischer-Tropsch reaction in the SASOL Synthol process at SASOL SynFuels, Secunda, South Africa. Distillation of the reaction water to remove non- and oxygenated hydrocarbons yields approximately 25 - 30 ML/d of an organic (carboxylic) acid-enriched stream (average COD of 16 000 mg/L) containing primarily C2 – C5 organic acids, light oils, aldehydes, ketones, cresols and phenols. Together with the Oily sewer water (API) and Stripped Gas Liquor (SGL) process streams, this process effluent

Il seguente elaborato nasce con l’obiettivo di applicare il concetto di biopiscina al brevetto Biodesign® presso l’azienda Actual Personal Irrigation (A.P.I.) Italia. La biopiscina ha lo scopo di fornire agli utilizzatori una zona balneabile dove l’acqua è trattata per via biologica da microorganismi, zooplancton, fitoplancton e piante. Ad oggi, il mercato della biopiscina è in forte crescita soprattutto nel nord Europa e in Italia. Visto il nuovo trend di mercato e la forte innovazione di A.P.I. Italia, è nata l'idea di testare due tipologie di filtrazione biologica a due vasche prova cost

Rice (Oryza sativa L.) crop has an important role to attend the food demand of a growing world population, and the production increment will come not just from increasing efficiency in the current cropland, but also from expansion to new areas. The tropical lowland plains of northern Brazil are already being converted to rice production, although the lack of scientific knowledge and agricultural practices suited local conditions. This region presents soils with weathered clays with distinct properties from those grown in traditional rice regions, and deploying agricultural practices developed

Dans ce travail, le traitement des nutriments et plus particulièrement celui de l’azote en procédé de granulation aérobie a été étudié. L’approche expérimentale a dans un premier temps eu pour objet de comparer la stabilité des caractéristiques physiques et microbiologiques d’agrégats développés dans deux réacteurs fonctionnant en alternances de phases anaérobie / aérobie ou anoxie / aérobie. L’opération d’un procédé de granulation aérobie en alternance de phases anoxie / aérobie a favorisé la stabilisation des performances de traitement de l’azote et notamment celle de la nitrification.

O crescimento acelerado da população idosa juntamente com o aumento da procura por atividades físicas tem motivado cada vez mais estudos que envolvam treinamento e o idoso. A corrida em piscina funda parece ser uma alternativa interessante para essa população, uma vez que não possui impacto nos membros inferiores possibilitando que o indivíduo se exercite em grandes cargas aeróbias com menor risco de lesão. Desta forma, o objetivo do presente estudo foi avaliar os efeitos de dois programas de treinamento em piscina funda nas respostas cardiorrespiratórias, neuromusculares e no equilíbrio de id

Water from Mantua reservoir has, during some years, exhibited reddish-brown staining when used by Brigham City for irrigation. I propose that seasonal fluctuations in the reservoir chemistry create an environment conducive to dissolving iron from the iron-rich sediments, which subsequently precipitate during irrigation, resulting in a staining event. These conditions are produced by chemical and biological decomposition of organic matter, coupled with isolation of the hypolimnetic waters, which results in seasonal low concentrations of dissolved oxygen in these waters. Under these specific cir

O processo de envelhecimento acarreta um declínio no equilíbrio postural, na força muscular e no condicionamento cardiorrespiratório, influenciando diretamente a capacidade funcional do idoso. No entanto, a prática sistemática de atividade física pode reduzir esses efeitos deletérios. Os exercícios realizados em meio aquático, como a hidroginástica, são adequados e seguros para essa população, devido ao reduzido impacto sobre os membros inferiores e à diminuição da sobrecarga cardiovascular. Assim, o objetivo do presente estudo foi analisar e comparar os efeitos de três métodos de treinamento

A água empregada na produção de doses inseminantes (DIs) de suínos pode ser um dos veículos de introdução de bactérias contaminantes, podendo levar à perda de qualidade das mesmas. O objetivo do presente estudo foi avaliar o número de mesófilos aeróbios totais (MAT) na água utilizada em centrais de inseminação de suínos e sua influência nas contagens bacterianas das DIs produzidas. Foram conduzidos três ciclos de amostragem em seis centrais de inseminação (A-F), intencionalmente incluídas no estudo de acordo com os critérios: estar localizada no sul do Brasil; produzir >1.000 DIs mensais; e co
