Tenders Are Invited For Electrical Installation Work Of Filtration Equipment - Increase In The Capacity Of Membrane Latel In Zone M Of The Seine Aval Site

Electrical Installation Work Of Filtration Equipment - Increase In The Capacity Of Membrane Latel In Zone M Of The Seine Aval Site. The Membrane Biological Treatment Sector Of Lusine Sav, Received In 2018, Is Made Up Of 2 Queues (A And B), Which Each Are Made Up Of 14 Tanks. Each Tank Has The Capacity Of 12 Cassettes To The Maximum. Currently, Only 10 Cassettes Are Deployed Per Tank. Finally, Each Cassette Is Made Up Of 48 Modules, A Total Of 13,440 Modules. - These Zenon Brand Membranes Had A Guaranteed Lifespan, With Regard To Filtration Performances, 7 Years.- A Study Piloted By The Innovation Department Suggests Renewing Cassettes From 2026 Taking Into Account 3 Scenarios Dutiilization Of Cassettes And Phenomena Of Observed Fiber Breakage. 2024, The Membrane Sector Treated On Average More Than 213,000 M³ Per Day, Which Represents An Ngl Reduction On Average Of 7.75 Tonnes Per Day. - In Order To Date The Objectives Of Ngl Performance For The Coming Years (71% In 2025, 72% From 2026), It Is Necessary To Replace The Membranes To Maintain The Availability Of The Process. The “Market Project Sheet” Relates To: - The Renewal, By A New Generation Of Membrane, Of The 13,440 Filtration Modules Of The Current Membrane Sector Including The Sérève Filtration Surface To More Than 456,000 M² Whose Warranty Duration Has Been Over Since February 2024 But According To The Si Simulations, We Will Start To Observe A Critical Level Of Permeability On 2 Tanks (On 28 Coves Total) From July 2025. - Laugation Of 10 To 12 Cassettes Per Tank Are 16,128 Modules For A New Filtration Surface Of 548,352 M², In Order To Dauge Our Filtration Capacity In Cutting Edge. This Extension Will Have To Be In The Volumes Of Existing Tanks To Diagnose And Repair Without Extension Or Construction Of New Works. It Will Incorporate The Additional Pipes And Additional Equipment Necessary For Its Operation. - The Resizing And The Renewal Of The 28 Discolving Overpectors With The Necessary Adaptations Of The Dair Distribution Aeraulic Network, Electrical Power Supplies And Operating Lautomatism. The New Installation Will Thus Make It Possible To Treat A Nominal Flow Of 4 M3/S And A Cutting Edge Of 6 M3/S With Compliance With The Ngl Yields Of The Deru. The Proper Functioning Of Decolchating Boosts Is Essential For The Availability Of Membranes In Their Filtration Capacities And Therefore Impacts The Defect Filtered By Cassette. The Treatment Performance Thus Conditioned By The Membranes Discolving Cycles, And Therefore By The Characteristics Of The Over -Sectors And Their Automation, Do Not Allow The Membranes To Be Replaced Separately, Their Extension And The Renewal Of The Overpressors Of Deciduousment. We Therefore Offer A Single Batch For Lensem
