Tenders Are Invited For Purification Plant Equipment - Execution Of Construction Works Consisting In The Construction Of A Dephosphatation Building With The Necessary Infrastructure On The Premises Of The Wrocław Wastewater Treatment Plant

Purification Plant Equipment - Execution Of Construction Works Consisting In The Construction Of A Dephosphatation Building With The Necessary Infrastructure On The Premises Of The Wrocław Wastewater Treatment Plant. 1. The Subject Of The Order Is The Execution Of Construction Works Consisting In The Construction Of A Dephosphatation Building With The Necessary Infrastructure On The Premises Of The Wrocław Wastewater Treatment Plant. 2. The Subject Of The Order Is The Construction Of A Building For The Installation Of Phosphorus Recovery In The Dephosphatation Process, I.E. Treatment Of Leachate From The Digested Sludge Dewatering Process, Together With Accompanying Facilities, On The Premises Of The Wrocław Wastewater Treatment Plant. 3. The Subject Of The Contract Must Meet: A) The Requirement To Achieve Phosphorus Recovery >70% For Leachates With A Phosphate Concentration Exceeding 95 Gp/M3 And Meet Other Requirements From Annex No. 1 To St-00 Conditions For Final Acceptance And Process Guarantee Of The Dephosphatation Installation, Which Will Be Confirmed By The Positive Completion Of Test No. Eutrophication, B) The Requirement To Achieve Phosphorus Recovery In A Wide Range Of Phosphate Concentrations In Leachates In Accordance With Annex No. 1 To St-00 Conditions For Final Acceptance And Process Guarantee Of The Dephosphatation Installation, Which Will Be Confirmed By The Positive Completion Of Test No. For Electric Drives Of Compressors And Pumps, D) Requirement To Use Led Lighting Technology With The Use Of Presence And Light Intensity Sensors And The Possibility Of Adjusting The Light Flux, E) Requirement To Regulate The Rotational Speed Of Electric Drives Using High-Current Frequency Converters, Selected According To The Technical Parameters Of The Powered Motors And The Technological Requirements Of The Installation. 4. The Individual Elements Of The Investment Include: A) Construction Of A Building For The Phosphorus Recovery Installation - Facility Po, B) Construction Of The Foundation For The Silo - Facility F1, C) Reconstruction Of The Compressor Room And Auxiliary Building. For A Power Generator - Structures B10, B19, D) Reconstruction Of The Building Of The Fan Station And Heat Exchanger - Structure B11, E) Reconstruction Of The Social And Technical Building - Structures B21-B24, F) Construction Of Installations And Inter-Facility Networks Together With Structures On The Networks, G) Construction Of A Sidewalk. 5. The Basic Assumption Of The Installation Is To Remove And Recover Phosphorus From The Leachate, Which Will Result In Minimizing The Additional Load Of Pollutants Flowing With The Leachate After The Dewatering Process To The Biological Blocks Of The Wrocław Wastewater Treatment Plant. 6. The Central Element Of The Phosphorus Recovery Installation Is The Crystallization Reactor, Into Which Leachate From Sewage Sludge Dewatering, Rich In Ammonium Ions And Phosphate, Is Pumped From The Bottom. 7. The Capacity Of The Installation, Calculated As The Amount Of Leachate After The Digested Sludge Dewatering Process, That Can Be Directed To It Is Qśrd - 1,160 M3/D. 8. Detailed Requirements Of The Ordering Party
