The NUF® technology: transforming Ultrafiltration in an affordable technology for water filtration and disinfection in swimming pools, Jacuzzis and spa's by Mino NEGRIN and Lior KOLLER, from NUFILTRATION.

1. THE NUF® TECHNOLOGY: TRANSFORMING ULTRAFILTRATION IN AN
AFFORDABLE TECHNOLOGY FOR SWIMMING POOLS’ WATER
TREATMENT
Mino Negrin – CEO and Owner

2. ULTRAFILTRATION (“UF”):
THE BEST AVAILABLE TECHNOLOGY (“BAT”)
FOR WATER TREATMENT IN SWIMMING

ULTRAFILTRATION:
• A mechanical removal of particles present in a
liquid, which size varies from 5 nm (=0.005
micron) to 100 nm (=0.1 micron)
• Takes place by the tangential or perpendicular
flow of the raw liquid on a semi-permeable area
(= membrane separation)
• The semi-permeable area (“the membrane”) can
be arranged in different configuration: spiral-
wound, plate and frame, hollow fiber

5. SIZE OF SELECTED PATHOGENS AND PARASITES
Size (micron)Organism/particle
1 – 4 micronE-coli
3 – 15 micronGiardia
3 – 6 micronCryptosporidium
1 – 3 micronLegionella
0.5 – 4 micronPseudomonas aeruginosa

UF - GENERAL FEATURES
• Excellent removal (up to 99.9%) of bacteria, viruses, organic matters,
turbidity agents, suspended and colloidal matters in the feed water
=> FILTRATION AND DISINFECTION OF WATER IN ONE SOLE PASS
• Mechanical removal by size exclusion – almost without usage of
chemicals or additives
• Low energy process (working pressure 0.5 to 1.5 bar)
• PROOFED AND WELL ESTABLISHED TECHNOLOGY IN THE WATER
TREATMENT FIELD

7. 712/30/2018
UF = BEST AVAILABLE TECHNOLOGY FOR WATER
TREATMENT IN SWIMMING POOLS, SPAS AND
THERMAL WATER
• FILTRATION AND DISINFECTION OF ALL POTENTIAL CONTAMINANTS
IN THE WATER BY MECHANICAL REMOVAL ONLY
• REQUIRES AS ADDITION ONLY AN EXTREMELY LOW DISINFECTANT
RESIDUAL EFFECT (i.e. 0.3 ppm of Cl2 in the water)
• DRASTICAL REDUCTION OF CHLORAMINE, THM’S AND DBPs
• DRASTICAL REDUCTION OF CHEMICAL USAGE
• CHEMICAL CONCENTRATION OF THE WATER REMAIN WITHOUT ANY
VARIATION

8. 812/30/2018
OTHER BENEFITS IN THE USE OF UF
AS PER DIN 19643-4:
•50% CIRCULATION RATE - HUGE ENERGY
CONSUMPTION SAVING
•0.3 – 0.6 ALLOWED FREE CHLORINE CONTENT IN
WATER
•DOUBLED “K” (FRENCH “FMI”) FACTOR

9. WHY UF IS ALMOST NOT USED IN
SWIMMING POOLS ??
• ULTRA-TRADITIONAL MARKET SCENE
• CONSIDERED AS TOO EXPENSIVE !!

MEMBRANE CHARACTERISTICS
• Originally designed, built, proofed and quality tested as a medical device
• ABSOLUTE filtration rate of 0.03 µ => nominal filtration rate of 0.003 µ
• Smooth membrane surface => low fouling and extremely easy to clean
• Robust: more than 3 years of continuous operation (and going on)
• Built-in mechanical filter – 200 µ
• In line steam sterilized => resistant to high temperature
• Unlimited availability
• Easy scalability : 1 unit = 100 lt/hr; 10,000 units in parallel = 1,000 m3/hr
