Description

The subject of the order is the delivery of 40 000 kg of polyelectrolyte powder for mechanical dewatering of sludge on centrifuges in the Wastewater Treatment Plant in Gorzów Wielkopolski, 158 Kostrzyńska Street.
The subject of the contract is the delivery of 40 000 kg of powder polyelectrolyte for mechanical dewatering of sludge on centrifuges in the Wastewater Treatment Plant in Gorzów Wielkopolski, ul. Kostrzyńska 158. The contractor should carry out a technical test of sludge dewatering on centrifuges using the offered polyelectrolytes. The weight of each of the tested polyelectrolytes is to ensure that the working solution is made in the polyelectrolyte dissolution station. The tests will be carried out with the use of polyelectrolytes delivered to the Wastewater Treatment Plant in Gorzów Wlkp., 158 Kostrzyńska Street, in original intact factory packaging, in the amount of at least 50 kg of product. Otherwise, the polyelectrolyte will not be approved for testing. Testing will be conducted by the Contracting Authority with the participation of the Contractor. The Contractor has the right to participate in tests on a technical scale. Should the Contractor fail to appear, the test shall begin without his presence, and the Contractor has no right to appeal against the results obtained. The test shall be concluded by signing a protocol. A scan of the protocol shall be sent to the Contractor by e-mail. The date of technical scale tests shall be indicated to the Contractor by phone when reporting for tests. The test shall be conducted not later than 10 working days before the opening date of the tenders. Conditions for conducting technological test:a) Results to be obtained during testing, for each single, taken sample:- centrifuge leachate: suspended solids content - max. 300 mg/l, - centrifuge sludge hydration - max. 79%.The condition for considering the offer for a given product is to obtain the above mentioned limit conditions.b) During the test, samples (sludge feed, dehydrated sludge and leachate) for laboratory tests shall be taken in the presence of representatives of the Economic Operator and the Contracting Authority: 4 samples at half-hour intervals from one centrifuge operation cycle with the use of tested polyelectrolyte.c) Until the first samples are taken, the Contracting Authority allows the following parameters to be adjusted by the Contractor: - change of polymer working solution dose (by changing the pump operation frequency),- basic differential speed in the range of 2.2-3.0 rpm,- load of planetary gearbox of the centrifuge 1.6-2.0 kNm.d) From the moment the first samples are taken for testing, the Contractor's representative may not change parameters of the set devices until the last, fourth sample for testing is taken (4 samples at half-hour intervals) ending the tests.e) Laboratory tests of the taken samples shall be carried out by the Ordering Party's Laboratory.f) The date of conducting the tests must be agreed with the Ordering Party.4The Ordering Party shall provide the Contractor with a protocol from the conducted test on a centrifuge, with a dose of polyelectrolyte calculated on the basis of averaged results, expressed in kg/t dry mass of dehydrated sludge. The Contractor is obliged, in Form no. 1, to indicate the consumption of polyelectrolyte (kg) for dehydration of 1 t of dry mass of digested sludge, in accordance with the protocol from the centrifuge test received from the Customer. The polyelectrolyte shall have a quality guarantee and warranty period of at least 6 months from the date of receipt without material defects. The Ordering Party shall require the execution of the order within 14 months from the date of signing the contract. The realization of the subject matter of the order shall be carried out successively only on the basis of specific orders of the Ordering Party in quantities specified in orders placed by telephone, fax or e-mail. The Contractor undertakes to deliver each time the subject of the order within 7 calendar days from the date of order placement. The Contractor is obliged to deliver the goods in bags of 25 kg polymer weight placed on a pallet with a total polymer weight of 1 tonne. Delivery and unloading of the subject of the order shall be done by the Contractor at his expense and risk to the Sewage Treatment Plant in Gorzów Wielkopolski, 158 Kostrzyńska Street.
