Condizione: Hervorragend. Zustand: Hervorragend | Seiten: 52 | Sprache: Englisch | Produktart: Bücher | This study aims to use jar tests to determine the best conditions for the physical-chemical treatment of refrigerant industry effluent, defining the dosages of alkalising agent (NaOH), coagulant (tannin) and oxidising agent (NaClO) for treatment at an activated sludge effluent treatment plant (ETE). To this end, coagulation/flocculation/oxidation tests were performed in Jar tests and physical characterisation of the sludge (series of solids, specific mass, density of solids and sludge) was carried out. In all stages, the variables analysed were: apparent colour, turbidity, COD, total phosphorus and BRIX. Among the dosages investigated, the best condition was obtained with values of 820 ppm of NaOH, 90 ppm of tannin and 1440 ppm of NaClO, which resulted in removals of 99%, 98.8% and 95.4% in apparent colour, turbidity and total phosphorus, respectively.…

Condizione: Hervorragend. Zustand: Hervorragend | Seiten: 56 | Sprache: Deutsch | Produktart: Bücher | Ziel dieser Arbeit ist es, anhand von Jar-Test-Versuchen die besten Bedingungen für die physikalisch-chemische Behandlung von Abwässern aus der Kühlmittelindustrie zu ermitteln und die Dosierungen von Alkalisierungsmittel (NaOH), Koagulierungsmittel (Tannin) und Oxidationsmittel (NaClO) für die Behandlung in einer Kläranlage (ETE) mit Belebtschlamm festzulegen. Zu diesem Zweck wurden Koagulations-/Flockungs-/Oxidationstests in Jar-Tests und eine physikalische Charakterisierung des Schlamms (Reihe von Feststoffen, spezifisches Gewicht, Dichte der Feststoffe und des Schlamms) durchgeführt. In allen Phasen wurden folgende Variablen analysiert: Farbe, Trübung, CSB, Gesamtphosphor und BRIX. Unter den untersuchten Dosierungen wurde die beste Bedingung mit Werten von 820 ppm NaOH, 90 ppm Tannin und 1440 ppm NaClO erzielt, die zu einer Entfernung von 99 %, 98,8 % bzw. 95,4 % der scheinbaren Farbe, Trübung und des Gesamtphosphors führten.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Celem niniejszej pracy jest zbadanie, poprzez testy w s¿oiku Jar, najlepszych warunków fizykochemicznej obróbki ¿cieków przemys¿owych z ch¿odziarek, poprzez okre¿lenie dawek ¿rodków alkalizuj¿cych (NaOH), koaguluj¿cych (tanina) i utleniaj¿cych (NaClO) do oczyszczania ¿cieków w oczyszczalni ¿cieków (ETE) za pomoc¿ osadu czynnego. W tym celu przeprowadzono testy koagulacji/flokulacji/utleniania w testach Jar oraz charakterystyk¿ fizyczn¿ osadu (seria substancji stäych, masa w¿äciwa, g¿sto¿¿ substancji stäych i osadu). Na wszystkich etapach analizowano nast¿puj¿ce zmienne: barwa, zm¿tnienie, ChZT, fosfor cäkowity i BRIX. Spo¿ród badanych dawek najlepsze warunki uzyskano przy warto¿ciach 820 ppm NaOH, 90 ppm taniny i 1440 ppm NaClO, które spowodowäy usuni¿cie odpowiednio 99%, 98,8% i 95,4% barwy widocznej, m¿tno¿ci i fosforu cäkowitego. …
