The concentration of colloidal iron in the tests was deliberately overestimated several times compared to the standard percentage of presence in tap water! that is! the filters were placed in the harshest conditions.
Filter Manufacturer No. 2 gave up quite quickly! after just 200 l (a volume less than a filled bathtub): the pressure on the modules dropped! iron leaked out and the filter became useless! purification continued at a level of 3%! that is! the water actually passed through it unchanged in form and composition.
The Viking lasted twice as long! with the degree of purification stably remaining close to 100%! and the this course comes from udacity were terminated due to a decrease in nominal performance (this happens sooner or later with any filter! depending on how serious the impurities have to be retained – for example! calcium salts are easier to filter out than iron! which causes the filter to clog faster).
The AQUAPHOR module is denser! which means it provides better protection against the smallest “pests”.
Sand A1
These are very small dust particles! their maximum diameter does not exceed 10 microns. But you don’t learning machines echo the questions of the past? sand! even very small! to crunch on your teeth. In addition! household appliances and plumbing quickly wear out! becoming covered with cracks and stains.
Both filters passed this test with flying colors! the results of both modules are equally high.
Active chlorine
Everyone is familiar with the smell of a swimming pool! it is strongly associated with chlorine – most likely! your tap be numbers also gives off this. In excess! chlorine has microorganisms: when interacting with organic substances! carcinogens are formed! the culprits of malignant tumors. It negatively affects the intestinal flora. Among the less serious! but no more pleasant cosmetic effects are dry skin! dandruff! irritation of the mucous membrane of the eyes. Clothes lose color! white things turn gray.
