20.500.12556/DKUM-17500 VPLIV FILTRA WATERPIK R-7 NA IZBOLJŠANJE KVALITETE PITNE VODE THE IMPACT OF WATERPIK R-7 FILTER ON DRINKING WATER QUALITY V nalogi smo želeli proučiti vpliv filtra waterpik R-7 na izboljšanje kvalitete pitne vode. Testirali smo filter R-7 waterpik, za katerega njegovi proizvajalci zagotavljajo, da zniža koncentracije lindana, azbesta, svinca, klora in nevarnih mikroorganizmov (ciste Giardia in Cryptosporidium) v pitni vodi. Zanimala nas je tudi učinkovitost filtra pri odstranjevanju atrazina iz pitne vode. Učinkovitost filtra smo ugotavljali z analizami splošnih parametrov in fizikalno-kemijskih parametrov na vzorcih neobdelane vode, vode po obdelavi z waterpik R-7 in vode po obdelavi z iztrošenim filtrom waterpik R-7. Opravili smo analizo s hitrim testom WS-425B in tako preverili vsebnost nezaželenih snovi v vodi po obdelavi z waterpik R-7. Ugotovili smo, da se v začetku zniža trdota, ki pa se po približno porabljenih 20 L približa vrednosti pitne vode. V začetku filtracije se je koncentracija K+ zelo zvišala. Po nekaj litrih iztočene vode pa se je njegova vrednost znižala na 8 mg/L. Znižale so se koncentracije svinca in atrazina v vodi obdelani z waterpik R-7. Nitrat se zniža in najverjetneje zamenja s kloridom. To vidimo v povečani prevodnosti. The objective of this diploma was to determine the impact of filter waterpik R-7 on drinking water quality. We tested filter waterpik R-7, for which we have a guarantee of a producer, that the concentrations of lindane, asbestos, lead, chlorine and dangerous parasites (cists Giardia and Cryptosporidium) are reduced through the filtration. We also wanted to study effectiveness of filter waterpik R-7 on atrazine removal in drinking water. The effectiveness of filter was determined by general and physical-chemical analysis on drinking water samples before being treated with filter waterpik R-7, samples after being treated with filter waterpik R-7 and samples after being treated with saturated filter waterpik R-7. We made the analysis with drinking water test WS–425B and so we determined if there is any contamination of unwanted substances in water after being treated with waterpik R-7. We determined that the rate of total hardness in water was lower at the start. After about 20 L of water was used, the hardness of water went near value of safe drinking water. In the start of filtration the concentration of K+ went very high. After a few L of water used, its value was reduced down to 8 mg/L. The concentrations of atrazine and lead in water samples were reduced after being treated with filter waterpik R-7. Nitrate was reduced and probably replaced with chloride. We see that as increased electrical conductivity. Pitna voda vodni blok filter adsorpcija. Drinking water block carbon water filter adsorption. true true false [N.
