TENDER DESCRIPTION

In wastewater treatment, various wastes are removed from the wastewater that must be disposed of. So far, there are only insufficient capacities for this. Therefore, a central treatment plant is to be constructed in which the sewer flushing waste arising throughout the entire association area, the sand trap waste - provided it originates from a wastewater treatment plant without a sand washer - and the deposits removed during the cleaning of aeration tanks can be treated. At least the following components should be planned for the treatment plant: - Receiving area for container vehicles and flushing vehicles (aqueous phase and solid fractions) - Washing drum for coarse material separation - Coarse material compactor - Buffer tank for sand-water mixture - Sand washer that guarantees a loss on ignition below 3% - Required conveying and dosing technology - EMSR technology - Discharge of the organically loaded wash water into the wastewater treatment plant
