Prior Information Notice For Construction Work – Post-Treatment In The Form Of An Extra Purification Step In The Amstelveen Sewage Treatment Plant. This Project Concerns An Additional Purification Step At The Amstelveen Wwtp That Improves The Water Quality Of The Amstel Through Better Effluent Quality. To Achieve This, The Technical Objectives For The Entire Purification, Including Expansion, Are As Follows: - Removal Of Micro-Pollutants Of At Least 80% Compared To The Wastewater Entering The Wwtp (A Purification Performance Applies For The Subsidy From The Ministry Of Infrastructure And Water Management Of At Least 80%); - Far-Reaching Nutrient Removal Compared To The Current Effluent Quality: - Primarily It Is Important To Remove Phosphorus (P) As Far As Possible; The Effluent Will In Any Case Not Contain More Than 0.25 Milligrams Of Phosphorus Per Liter Of Wastewater (Based On A Moving Annual Average); - The Removal Of Nitrogen (N) Is Important Because Of The Ratio Between Nitrogen And Phosphorus On The Amstel And In Amsterdam, And Because Nitrogen Plays An Important Role In The Brackish Water Of The North Sea Canal And The Coastal Zone; The Moving Average Effluent Concentration Of Nitrogen Over One Year May Not Exceed 5 Milligrams Per Liter Of Waste Water; This Results In A Reduction For The North Sea Canal And Coastal Zone And The Ratio Between Nitrogen And Phosphorus In The Amstel Does Not Increase; - Realization Of Disinfection Step Up To 1,800 Cfu E.Colli / Dl To Promote Bathing Water Quality In The Amstel. To Achieve These Objectives, An Expansion Of The Existing Wwtp Is Required.
