The invention relates to a mobile system for purifying micro-biologically and chemically contaminated water sources and preparing drinkable water, said system comprising a chemical multimedia filter, and to the operation thereof. After being processed, the water is safe for drinking. Owing to its construction and mobility, the system is particularly convenient for field use. The mobile water purification system of the present invention comprises a housing, a pump, a system of conduits for interconnecting the individual system components, a mechanical spin-down filter operating as a prefilter, an ultrafiltration module, a chemical multimedia filter, a UV sterilizer, and a microprocessor controller. Optionally, the system may be provided with ion exchangers, preferably upstream of the chemical multimedia filter. The essential advantage of the system over other similar systems lies in its self-cleaning chemical multimedia filter, which is composed of/loaded with different media, selected case by case according to the specific type of polluted water involved. This allows the system to comprehend a range of diverse embodiments according to the type of pollution of the water source, allowing the system to be "custom-tailored". All filtration components, that is modules, are self-cleaning in that they allow backwashing by means of a counter-current. This extends the life cycle of a filter, also increasing its capacity before a filter is exhausted and needs replacing or regenerating. |
