- Crystal clear water: filters much finer than quartz or glass sand. At 20 m/hr filtration speed a nominal filtration of 5 microns is achieved without flocculation With optimised coagulation and flocculation with .
- Lower chlorine consumption means less secondary chlorine reaction products: chlorine is an excellent disinfectant. But in reaction with organic and inorganic substances it also produces undesirable, harmful reaction by-products such as trichloramine and THM's. The more chlorine is consumed the more secondary reaction by-products are produced. With AFM® we can remove far more substances than with sand or glass sand. This applies particularly in connection with coagulation and flocculation. Everything that can be filtered out and removed in backwash process doesn't have to be oxidised. The better the filtration the lower the chlorine consumption and less disinfection by-products are produced.
- Bioresistant no home for bacteria, viruses and other pathogens: sand is a good mechanical filter but it's also an ideal breeding ground for bacteria. Within just a few days every grain of sand is colonised by bacteria. They immediately form mucus to protect themselves against the disinfectant. In this so-called Ťbiofilmť live entire communities of bacteria and other pathogens including Legionella. If you have no organic film in your filter there are also no Legionella.
- No trichloramine and no chlorine smell: the bacteria in the biofilm convert urea into ammonia which then reacts with chlorine to inorganic chloramine (mono, di- and trichloramine). Trichloramine causes the unpleasant chlorine smell and is also a severe health hazard. If however, no heterotrophic bacteria are present, urea remains in the water. It reacts with chlorine to the harmless chlorine urea. No biofilm no trichloramine - no chlorine smells.
- Filter function remains good with AFMŽ for many years: No biofilm in the DSG filter also means no channelformation to disrupt the filter function. Due to filter contamination the performance of a sand filter worsens dramatically after 6 - 12 months despite frequent backwashing. The performance of DSG® remains consistently high for many years.
