Opis:	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.
Ključne besede:	Pitna voda, vodni blok filter, adsorpcija.

Naslov:	THE IMPACT OF WATERPIK R-7 FILTER ON DRINKING WATER QUALITY
Opis:	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.
