Delivery of a carbon source
About This Opportunity
TranslatedThis tender is for the supply of approximately 1,200 tons of a carbon-containing substance to be used as an additional carbon source in the aeration process of the Halle-Nord wastewater treatment plant. The supply will be based on an attached framework agreement for the entire contract duration. The contracting authority estimates the uptake quantity at approximately 1,200 tons. However, the actual uptake quantity is not predictable, as it depends on the required dosage for the desired biological degradation process, the wastewater composition, and ambient temperatures. The supplier must therefore anticipate quantity reductions of up to 20% and increases of at least 20% within the 24-month period, based on the wastewater conditions and required dosage. It is also expected that deliveries will not be continuous but subject to significant fluctuations throughout the year. The supplier guarantees that the carbon source supplied will not contain any substances that negatively impact the biological degradation process in the aeration stage of a wastewater treatment plant. Furthermore, the product must not contain any water-polluting or settlable substances. The supplier also guarantees that the product will maintain its specified properties throughout the contract duration, as detailed in the product data sheet provided during the bidding process.
This is a supplies contract in the trade and industry sector, with a focus on Quality Standards. Located in Germany, Europe, this opportunity is open to firms and consortiums.

Description
Auto-translated from GermanThe subject of the contract is the delivery of approx. 1,200 t of a carbon-containing substance, which will be used as an additional carbon source in the biological treatment of the Halle-Nord wastewater treatment plant throughout the entire contract period based on the attached framework agreement. The client estimates the acceptance quantity at approx. 1,200 t. Since the actual acceptance quantity depends on the required dosage for the desired biological degradation process, as well as on the composition of the wastewater in the biological treatment and the prevailing temperatures, the actual acceptance quantity cannot be predicted. The contractor must therefore expect quantity reductions of 20% and quantity increases of at least 20% within the 24-month period with regard to the required dosage based on the condition of the wastewater. It must also be assumed that deliveries will not be continuous in equal quantities throughout the year, but that delivery quantities may fluctuate significantly. Furthermore, the contractor guarantees that the carbon source supplied by him does not contain any substances that negatively affect the biological degradation process in the biological treatment of a wastewater treatment plant. The product must not contain any substances hazardous to water or any settable substances. The contractor further guarantees that the product supplied by him will maintain the product properties during the contract period that correspond to the product data sheet, safety data sheet, and material sample handed over during the bidding process. The client reserves the right to carry out a bioluminescent bacteria toxicity test according to DIN EN ISO 11348-1 2009-05 and a nitrification inhibition test according to DIN EN ISO 9509 (L38) 2006-10 to ensure compatibility with the biological degradation process. According to DWA-Merkblatt 115-2 Annex A. The contract begins on 01.04.2026. The contract ends on 31.03.2028 without the need for termination. However, the client is granted the right to extend the contract term by one additional year, i.e., until 31.03.2029, under the same conditions by unilateral declaration (extension option of the client), if he exercises this extension option in writing by 15.09.2027 at the latest and the contractor does not object to this extension option in writing within 14 calendar days of receipt of the declaration of exercise of the extension option. If the contractor objects to the extension option in due time, the contract ends on 31.03.2028. The remaining conditions for contract execution and contract terms are set out in the attached framework agreement.
