SFC - Model C-MEM -Ultrafiltration Technology

Although C-MEM has only one process step, it can replace conventional technology with flocculation – sedimentation – sand filtration and also reaches far better effluent values in Addition.

Basically, there are two designs of C-MEM for drinking water production: either as Gravity Driven Membrane (GDM) for small plants (C-MEM Zero) or mobile / fixed installed plants with electric pumps for higher flows. The plants can be operated with pressure or underpressure.

• Highly efficient separation of bacteria and virus (10⁴ – 10⁷ fold reduction) of any kind in one process step (physical barrier).
• Conventional flocculation – sedimentation – sand filtration can be omitted. The plant gets much more compact.
• Compared to sand filters the Membrane cannot break.
• Bacteria and virus are separated and not only inactivated.
• There are no side products and odour emissions.
• The drinking water produced is colourless, odourless and neutrally flavoured (provided there are no other additional process steps).
• Very mobile application of GDM in disaster areas or for expeditions.
• The membranes have a long lifetime and are cheaply and easily replaceable.

• Production of drinking water (from river water, lake water, spring water, rain water)
• Decentralized water filtration in isolated villages without electricity, camping, expeditions, disaster regions etc.
• Swimming pools
• Fish and swimming ponds
• Production of service water
