Perfector-E compact water treatment system.Each Perfector-E unit is a plug-and-play system powered by a generator. Using the equipped submersible pump, water is taken from the source and is fed directly into the Perfector-E unit. A pre-filter strainer removes larger particles from the feed water. From there the water is filtered through Norit X-Flow's proven UF membranes, which remove suspended solids including viruses and bacteria. The UV light acts as a secondary barrier to protect against contaminants.
