Other disinfection methods are being tested (such as fluoridation and ozonation)! but in regions where new technologies have not yet reached! there is little choice. So it is too early to give up chlorine: when the Peruvian authorities rashly decided to do so in 1991 in the hope of reducing the number of cancer cases! an outbreak of cholera occurred.
During the test! our filter maintained a consistently high level of purification and worked 10 we can’t control everything longer than the product of Manufacturer No. 2! which “burst” quite quickly! after which the filtration quality dropped sharply from 90 to 15%.
Participants: AQUAPHOR Crystal! AQUAPHOR Crystal ECO PRO! products of Manufacturers No. 2 and No. 3.
Applicable standards: GOST and NSF
The second test compared other filter models! and another manufacturer appeared among the opponents. A total of 4 models participated (AQUAPHOR Crystal! a universal flow filter! AQUAPHOR Crystal ECO PRO! designed for 100% removal of bacteria! as well as two products from Manufacturers No. 2 and No. 3). Other impurities different kinds of errors used! chloroform and lead. The obtained values were compared with the requirements of standards (GOST and NSF).
1. Chloroform
It is not so much chlorine itself that is dangerous! but rather the products of its interaction with be numbers substances! in particular! chloroform. This is a truly dangerous oncogenic organic compound of chlorine. In its removal! Crystal ECO PRO surpassed Manufacturer No. 2 in the first 500 liters. The performance of the competitor’s filter began to noticeably decrease and eventually dropped to the level of removing 50% of the hazardous substance.
Crystal ECO PRO throughout the test! i.e. until the natural decrease in productivity after 5000 liters! continued to remove at least 95% of volatile and 73% of non-volatile organic substances. This is a very high figure.
A similar picture was observed in the case of the other two modules – the filter of Manufacturer No. 3 also lasted only 500 liters! after which the quality of purification rapidly dropped. Crystal filtered 10 times longer before giving up its positions.
