Abstract:V diplomskem delu smo želeli vodo iz reke Save s kombinacijo koagulacije in flokulacije pripraviti za uporabo kot tehnološko vodo v podjetju VIPAP VIDEM Krško, d.d., ki je največji proizvajalec papirja v Sloveniji. Ker je dobavitelj iz prodaje umaknil polielektrolit, ki so ga do sedaj uporabljali v podjetju, je nastala potreba po zamenjavi. Namen je bil izmed koagulantov (ECO, ORG, KEMI in ALS) in polielektrolitov (MAG, SUP A100, AME in SUP C496) izbrati najboljšo kombinacijo ter koncentracijo na podlagi znižanja motnosti, ki je bil poleg pH-ja, prevodnosti in trdote, glavni kriterij za izbor najučinkovitejšega polielektrolita. Tako smo na podlagi jar testov ugotovili, da največje znižanje motnosti dosežemo z uporabo Al2(SO4)3 v kombinaciji s SUP C496. Motnost se je znižala iz 14,8 na 2,7 NTU. Nato smo z volumetričnim preskusom za usedljivost snovi v vzorcih ugotovili, da je najhitrejše posedanje flokul z isto kombinacijo z drugačnimi koncentracijami. Zaključimo lahko, da je najboljša kombinacija Al2(SO4)3 in SUP C496, ki se že uporablja v podjetju.

Title:THE COMPARISON OF POLYELECTROLYTE EFFICIENCY BY PROCESS WATER TREATMENT IN VIPAP COMPANY
Abstract:In this thesis, we deal with water from the Sava river conditioning with a combination of coagulation and flocculation, to be used as process water in company VIPAP VIDEM Krško, d.d., the largest producer of paper in Slovenia. As the supplier withdrew polyelectrolyte from the sale, there has been created the need for replacement. Our intention was that of coagulants (ECO, ORG, KEMI and ALS) and polyelectrolytes (MAG, SUP A100, AME and SUP C496) we choose the best combination and concentracion based on the reduction of turbidity, which was in addition to the pH, conductivity and hardness, the main criterion for the selection of the most effective polyelectrolyte. So based on jar tests, maximum reduction in the turbidity was obtained by the use of alum in combination with SUP C496, reduced from 14.8 to 2.7 NTU. Then we did volumetric test for sedimentation of flocs in the samples. The fastest settling floc was achieved by the same combination, with different concentrations, so based on all criteria, we concluded that the best combination of coagulant and polyelectrolyte was the one which is already used in the company.
