Tenders Are Invited For Reconstruction Of The Sewage Treatment Plant In Sobótka - Design Documentation

The Scope Of The Task Includes The Development Of Design Documentation For The Reconstruction Of The Sewage Treatment Plant In Sobótka. The Main Goal Is To Improve The Quality Of Discharged Treated Sewage. The Sewage Treatment Plant In Sobótka Is A Mechanical And Biological Treatment Plant Superbos-2500, With Parameters Qaverage = 2500 M3/D, Designed For An Amount Of 14,800 M.A.) In Terms Of The Mechanical Sewage Treatment Unit: - Construction Of A Wastewater Tanking Station - The Installation Of A Collection Point Is Planned. Sewage Controlling The Parameters Of The Delivered Sewage. This Point Should Be Equipped With A Typical Tanker Connection, Measurement Of The Quantity And Quality Of Sewage With A Sample Collector, A Sieve, A Screening Press, A Stone Catcher And A System For Identifying The Origin Of Sewage. Range Of Parameters To Be Tested: Ph, Temperature, Conductivity, Redox Potential, Cod. - Construction Of A Retention Tank - Construction Of A Retention Tank Allowing For The Regulation Of A Stable Inflow Of Sewage To The Sewage Treatment Plant And Allowing For The Averaging Of Pollutant Loads. - Modernization Of Raw Sewage Pumping Station - Renovation Of The Grate Chamber Located In Front Of The Raw Sewage Pumping Station - Superstructure Of The Grate Chamber, Protection Of The Structure, Replacement Of Screw Grates With A Stepped Grate, Construction Of A Shut-Off Gate Valve With An Electric Drive On The Dn 800 Pipeline Supplying Sewage To The Treatment Plant, Along With Flood Protection. Renovation Of The Pumping Station Tank - Protection Of The Structure, Replacement Of Piping And Necessary Fittings, Replacement Of Pumps Forcing The Biosorption Tank. - Modernization Of The Biosorption Tank - Cleaning Of The Tank, Renovation And Protection Of The Tank Structure, Replacement Of Piping And Necessary Fittings, Replacement Of The Mixing And Aeration System, Construction Of A Bypass Enabling The Bypassing Of The Biosorption Tank And Transport Of Sewage From The Pumping Station Directly To The Superbos-1000 And Superbos-1500 Treatment Plant Blocks - Proportionally For Each Block Or Only For One Or The Other Block, Replacement Of Blowers Aerating Devices - 2 Pcs. With A Power And Control Cabinet. Installation Of A Probe With Transducers For Testing The Parameters Of Dispersed Oxygen, Ph, Temperature, Conductivity, Redox Potential, Cod And Tds. B) In Terms Of The Biological Sewage Treatment Unit: - Construction Of A Coagulant Storage And Dosing Station - In Order To Reduce The Concentration Of Nutrients In Treated Sewage, It Is Planned To Install A Pix Storage And Dosing Installation For Simultaneous Precipitation Of Phosphorus And A Pax Installation For The Removal Of Filamentous Microorganisms. The Dosage Of The Coagulant Should Take Place As A Function Of The Instantaneous Flow Of Raw Sewage, Therefore An Electromagnetic Flow Meter Is Planned To Be Installed In The Discharge Pipe. - Modernization Of The Sewage Aeration System - Replacement
