Ultrafiltration
The biggest advantage of ultrafiltration is that the purified water quality is many times
better than that produced with other techniques. A UV installation kills 99.9% of bacteria
and viruses, but cannot be applied in every situation. Similar rates also apply to heaters since an UF membrane has a filtration degree of 99.999999% on bacteria and 99.999% on virusses. This
means that the effect of ultra-filtration is much higher in comparison to a UV installation or
a heater. An additional benefit is that less or almost virtually no biofilm forms inside the
pipelines. As a result organisms do not have a breeding ground that allows them to grow or
regrow inside the piping. Other disinfection methods do not prevent this.
Another major benefit is low energy consumption. There is no gas consumption and the
high electricity consumption associated with UV lamps is lacking. Energy consumption is
often less than 0.2 kW/m3/h.
Furthermore, ultrafiltration combines well with the use of expensive nutrients, such as iron
chelates. As a result of the clean product water, minimal dosing of chlorine or peroxide is
sufficient to keep infection pressure behind the system under control. This is the reason
why users are satisfied with their return on investment.
