Tenders Are Invited For Successive Delivery Of Polymer For Dewatering Digested Sludge At The Waste Managemen ... in Poland

Work Detail

1. The Subject Of The Order Is The Successive Deliveries Of Polymer For Dewatering Digested Sludge At The Waste Management Plant In Konieczni, Commune. Osieczna (Zzo In Trzynia). Sludge For Dewatering Is Produced In The Process Of Dry Fermentation Of Selectively Collected Biodegradable Waste With Code 20 01 08 And 20 02 01.2. The Estimated Amount Of Dewatering Polymer Digested During The Order Execution Period Is Approximately 24 Mg.3. The Ordering Party Informs That The Amount Of Polymer Given Above In Point 2 Is An Estimate, Illustrating The Possible Size Of The Scope Of The Subject Of The Order And May Be Changed, Depending On The Needs Of The Ordering Party, While The Ordering Party Ensures The Minimum Amount Of Polymer In The Amount Of 15 Mg. Due To The Above, The Supplied Polymer In An Amount Less Than The Estimated Amount, But Not Less Than The Minimum Total Amount Of Polymer Supplied Specified Above, I.E. 15 Mg, Does Not Give Rise To Any Liability On The Part Of The Ordering Party, And The Contractor Will Not Be Entitled To Any Claims In This Respect. 4. The Temperature Of The Sludge Before Dewatering Is Approximately 50C. The Dry Weight Of Sludge Before Dewatering Ranges From 30-40% Of Dry Matter. The Dewatering Device Is An Anhydro Filter Press Type Vetter Screw Press Fvv. The Leachate From The Press Resulting From Sludge Dewatering Is Directed To The Sand Trap And Then To The Alfa Laval Centrifuge Type Aldec G2 45 To Remove The Suspension. To Increase The Effectiveness Of The Centrifuge, A Diluted Polymer Solution, Which Is The Subject Of The Order, Will Be Added To The Leachate. Part Of The Purified Leachates Is Used For Technological Purposes In The Process Of Dry Biofraction Fermentation To Regulate The Moisture Of The Feedstock. 5. The Alltech Polymer Preparation Station, Type Cf2000, Is Designed To Use Polymers In The Form Of Granules And Prepare A Solution From The Above-Mentioned Granules With A Concentration Of Up To 5.0%.6. Required Polymer Characteristics And Product Effectiveness:I. Shelf Life Of Granules In The Original Packaging - 12 Months. The Flocculant Should Have Certificates Of Quality Required By Law And A Safety Data Sheet, Which The Contractor Is Obliged To Attach To The Offer. The Packaging Of The Delivered Product Should Have A Description In Polish. Ii. Polymer Characteristics:A. High-Cationic Flocculant With Increased Molecular Weightb. Cationicity – 85%C. Molecular Weight 15 Million Dad. Form – Granulate, Non-Dusting. Viscosity At 20C (Using Distilled Water): - Cps Of 0.5% Solution - About 450 Mpa*S- Cps Of 0.1% Solution - About 35 Mpa*Sf. Bulk Density – 650 Kg/M3.G. Completely Soluble In Water During Solution Preparation. Iii. Required Dry Weight Of Sludge After Dewatering: Greater Than Or Equal To 60% Dry Weight. Using A Solution Dose Of Not More Than 180 Kg Per 1 Mg Of Digested Sludge, With A Solution Concentration Of 4.2%. Iv. Before Submitting An Offer, The Contractor Must Perform Technical Tests To Se
