Studien zur Entfernung von Nitraten aus Industrieabwssern by Meena Vangalapati, Sruthi Saladula Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Das Industrieabwasser wurde mit beiden Anlagen vergleichsweise behandelt und diejenige, die die stärkste Denitrifikation ergab, wurde für die Säulenbehandlung verwendet. Zusammen mit der Vorbehandlungstechnik namens Koagulation und Flockung wurde sie durchgeführt, um die gesamten suspendierten Feststoffe zu entfernen, Gerüche und in gewissem Umfang auch Farbe zu beseitigen. Koagulation und Flockung wurden als Vorbehandlungstechnik mit Koagulationshilfsmitteln wie Alaun, CaCo3 und PVA durchgeführt. Die Vorbehandlung wurde mit unterschiedlichen Mengen an Alaun (v/v) und Kontaktzeiten (min) durchgeführt. Nach der Vorbehandlung des Stahlwerkabwassers wurden beide Behandlungstechniken durchgeführt. Die vergleichende Studie zwischen den beiden Hülsenfruchtpflanzen Tamarindus indica und Vigna radiata ergab, dass die Nitrate in gewissem Umfang reduziert wurden und der Immobilisierungsschritt zu einem maximalen Denitrifikationsgrad führte.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
