English summary

Machine translated from German by FreeTender. The original notice below is the binding text.

The subject of the invitation to tender is the supply and service of flocculants for the Koblenz sewage treatment plant. The Koblenz sewage treatment plant mainly treats municipal wastewater. However, with a population value of around EW 154,000 (in 2022), it handles less freight than originally planned. 126,000 inhabitants are connected to the real (population EZ). The remaining 28,000 population equivalents (EEC) are of industrial origin (EC+EEC=EW). This results in an industrial share of the wastewater to be treated of around 18%.

Details

Gegenstand der Ausschreibung ist die Lieferung und Dienstleistung von Flockungsmittel für das Klärwerk Koblenz. Die Kläranlage Koblenz behandelt hauptsächlich kommunales Abwasser. Laut Bescheid hat sie eine Ausbaugröße von 320.000 EW. Mit einem Einwohnerwert von rund 154.000 EW (in 2022) behandelt sie jedoch weniger Fracht als ursprünglich vorgesehen. 126.000 Einwohner sind reell angeschlossen (Einwohnerzahl EZ). Die restlichen 28.000 Einwohnergleichwerte (EWG) sind industriellen Ursprungs (EZ+EWG=EW). Damit ergibt sich ein Industrieanteil des zu behandelnden Abwassers von rund 18%. Haupteinleiter sind die Papierindustrie, das Metallgewerbe und eine Mälzerei. Die maschinelle Faulschlammentwässerung erfolgt mit zwei Dekantern (X4E-4/454, BJ 2023). Die Entwässerung soll mit bestmöglichem Austrags TR bei optimalem Polymerbrauch durchgeführt werden. Der Abscheidegrad liegt bei > 98% (gem. DWA M-383); das Zentrat wird zurück zur Kläranlage geleitet. Für die Eindickung und Entwässerung wird ein Emulsionspolymer eingesetzt. Der anfallende Überschussschlamm wird mit drei Zentrifugen (GEA UCD 346 BJ 2012) unter Einsatz von Emulsionspolymeren maschinell eingedickt.

Documents

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this manufacturing & supply opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
