Ultrafiltration System

Membrane Technology Ultrafiltration is a physical process called “low pressure” where clarification and disinfection is performed in a single step. The wall acts as a filter for particles larger than 20 nm (pollen, algae, parasites, viruses, bacteria and organic molecules).
This technology ensures a constant and perfect water quality regardless of variations in the quality and turbidity of the water to be treated. In addition, this method is purely mechanical; it reduces the use of chemicals and waste treatment, while maintaining the mineral balance of the water.
Ultra resistant ZeeWeed* 700B/Sevenbore* membrane, polyethersulfone The fibres are bundled into groups of 7, which makes the membrane more mechanically resistant than individual fibres.
• High operating reliability and robustness • Long service life significantly reducing maintenance costs
• High level of filtrate quality
• High chemical resistance
• Tolerance over a wide pH range (pH 1 to pH 13)
• Permanent antifouling properties • Low pressure filtration < 0.3 bar
• Drinking water approvals in many countries • Raw water maximum turbidity of 100 NFU with peaks of 300 NFU tolerated Advantages • Physical treatment process where clarification and disinfection are performed in a single step
• A constant water quality, whatever the raw water variation • Production without any chemicals added to the treated water • Free of micro-organisms such as algae, bacteria, parasites...
• Safe and clean water quality • Preservation of mineral salts (calcium, sodium, potassium) aquasource Ultrafiltration 0.02 µm Sand filtration 10 µm Screening Microfiltration 0.1 µm Algae Pollen Parasites Bacteria Viruses Organic Macromolecules Mineral Salts Raw water Ultrafiltered water 100% of mineral salts preserved 500 times greater filtering power than a sand filter 6 log of bacteria and kystes removas.
