Biopolymer Recovery from Aerobic Granular Sludge and Conventional Flocculent Sludge in Treating Industrial Wastewater: Preliminary Analysis of Differ…

2022

The recovery of biopolymers from sewage sludge could be a crucial step in implementing circular economy principles in wastewater treatment plants (WWTP). In this frame, the present study was aimed at evaluating the simultaneous production of polyhydroxyalkanoates (PHA) and extracellular polymeric substances (EPS) obtainable from the treatment of agro-industrial wastewater. Two biological enrichment systems, aerobic granular sludge (AGS) and a conventional activated sludge operating as a sequencing batch reactor (SBR), were monitored for 204 and 186 days, respectively. The maximum biopolymers accumulation capacity was close to 0.60 mgPHA-EPS gVSS−1 in the AGS when operating at 3 kgCODm…

Physical dispersion and disappearance of bacteria in the Golfo di Palermo: the results of two surveys.

2012

This paper reports on some results of two surveys at sea carried out in the surroundings of a urban wastewater discharge on the coast of the Golfo di Palermo, western Sicily (Italy). At the time of the surveys (year 2005) the stretch of water lying before the central part of the capital town received the untreated wastewater originating from about 200 000 inhabitants, which was discharged on-shore without any prior treatment by the free-surface outfall of “Porta Felice main sewer”. This outfall has crucial importance in the water quality; indeed, the Municipality is steadily implementing a plan featuring an intercepting main sewer along the coast and some pumping stations to connect all the…

Proceedings of Frontiers International Conference on Wastewater Treatment May 21-14, 2017, Palermo, ITALY

2017

Today multidisciplinary is a key and a must for solving issues in the water field. The works in several International Water Association Specialist Groups have demonstrated the importance of both innovative technologies and mathematical modelling, and that the exchange of scientific and technical information among researchers and practitioners involved in these fields is crucial for effectively advancing knowledge.

Phosphorus recovery from mixed microbial culture: production and extraction through green methods

2018

Large scale polyhydroxyalkanoates (PHA) production is limited by high production costs compared to that of petroleum-based plastics. Two key factors can be pin down to reduce costs: i) the use of mixed microbial cultures (MMC) instead of pure cultures and ii) the application of cheap and environmental friendly recovery technologies. In this work, the MMC biomass with PHA-accumulating capacity was selected in a sequencing batch reactor fed with a synthetic effluent emulating a fermented oil mill wastewater. The biomass was harvested and transferred to an accumulation reactor, where PHA contents up to 54% of the dry cell weight were obtained, using a mixture of acetic and propionic acids. A c…

Apģērbu uzņēmumu grafiskās identitātes vizuāli stilistiskie aspekti

2018

Jebkuras sfēras produkta vai pakalpojuma vizuālajam izskatam ir liela nozīme mūsdienu tirgū. Patērētāji galvenokārt veic izvēli, balstoties uz produkta vai pakalpojuma vizuālo noformējumu un atpazīstamību. Arī apģērbu uzņēmumam vizuālā identitāte ir neatņemama zīmola izveides sastāvdaļa, kura norāda uz produktu kvalitāti, oriģinalitāti un spēju pastāvēt konkurentu vidū. Uzņēmumam izveidota vizuālā identitāte, kas atbilst un atspoguļo tā būtību un raksturu, ir veiksmes atslēga uzņēmējdarbībā. Lai izprastu vizuālo identitāti un tās nozīmi, bakalaura darba teorētiskajā daļā tiek apkopotas dažādu autoru atziņas un viedokļi par vizuālās identitātes jēdzienu, tās elementiem, to uzbūvi un nozīmi. …

Las reglas de Rotterdam sobre transporte marítimo internacional: la delimitación del ámbito de aplicación

2016

El presente trabajo analiza la propuesta de la UNCITRAL conocida de forma generalizada como las Reglas de Rotterdam a favor de la unificación de la regulación del transporte marítimo internacional. Concretamente, estas Reglas no pueden considerarse en una tradición puramente continuista a sus antecesoras y vigentes Reglas de la Haya y de Hamburgo. Precisamente por la importancia de los cambios que introducen las Reglas de Rotterdam, resultan de especial importancia los criterios de delimitación del ámbito de aplicación tratados en el presente trabajo. La aceptación por parte de los Estados miembro para su futura entrada en vigor, y sobre todo, los cambios materiales relativos la ampliación …

Nogāžu procesu monitorings ar lāzerskenēšanas metodi

2019

Pētījuma ietvaros, nogāžu procesu attīstības novērošanai, tika izmantots sauszemes lāzerskeneris Faro FocusS 70. Lauka pētījumi veikti trīs etalonteritorijās, apsekojot – Vizuļu iezi, noslīdeni, netālu no Zanderu kapiem, pie Līgatnes un noslīdeni, netālu no Gūtmaņalas, pie Siguldas. Lāzerskenēšana veikta 2018. gada rudenī un 2019. gada pavasarī. Lauka pētījumu laikā etalonteritorijās izveidoti paliekoši atbalsta punkti, kas vēlāk izmantoti atkārtotā apsekojuma laikā. Lai piesaistītu skenēto materiālu koordināšu tīklam, atbalsta punktiem noteiktas koordinātas, izmantojot GNSS. Virs tiem 2 m augstumā tika uzstādīti statīvi ar sfērām un apkārtnē pie noslīdeņa/atseguma virsmas, to tuvumā vai pi…
