Hyflux Polymeric Hollow-fiber Membranes

Ntesco has signed an agreement with Hyflux Ltd for the distribution of Kristal® hollow-fiber ultrafiltration membranes manufactured in modified polyethersulfone (or as option in PVDF for special applications), which are available for various applications:

• pre-treatment of sea water - (Magtaa - Algeria, is the largest desalination plant - 1 million m3/d permeate)
• pre-treatment of surface water
• production of drinking water, also for bottling
• re-use of industrial wastewater and effluents
• treatment by third parties of civil and industrial wastewaters
• thermal-water treatment

The hollow-fibre ultrafiltration membranes operate at relatively low pressures, have high filtering surfaces and ensure a high quality of the permeate, which results in thefollowing advantages:

• high efficiency
• low investment costs
• low running costs

It is seen as a competitive application with respect to traditional water treatment technologies. Ultrafiltration as a form of pre-treatment to reverse osmosis system ensures for the osmosis membranes:

• practically total elimination of colloidal deposits, bacteria and algae
• minor issues related to fouling and bio-fouling
• longer life
• substantial energy savings
• increase in production capacity

In addition, this application is characterized by:

• high flexibility on the basis of the characteristics of the food product and the recovery percentages (> 90%)
• a modular configuration and simple system management

With the NSF International (National Sanitation Foundation) certification and FDA (Food and Drugs Administration) approval for their excellent quality of filtration and operationalstability, the Hyflux Kristal ® 600ET model membranes are used in the process of purifying and bottling water for human consumption. Each KRISTAL® model can be assembled with fibers of different construction characteristics
