F Removal from Water and WasteF Removal from Water and Wastewater using Purolite SST 60

Diseases caused by F in Potable water

1. The fluoride goes to everyone regardless of age, health or vulnerability2. Fluoride may damage the brain3. Fluoride may lower IQ.4. Fluoride may cause non-IQ neurotoxic effects5. Fluoride affects the pineal gland.6. Fluoride affects thyroid function.7. Fluoride causes arthritic symptoms

7. Fluoride causes arthritic symptoms8. Fluoride damages bone9. Fluoride may increase hip fractures in the elderly.10. People with impaired kidney function are particularly vulnerable to bone

damage11. Fluoride may cause bone cancer (osteosarcoma)12. Fluoride may cause reproductive problems.

INDIAN STANDARD SPECIFICATIONS FOR DRINKING WATER IS: 10500

Fluoride 0.6 to 1.2

If the limit is below 0.6 water should be rejected, Max. If the limit is below 0.6 water should be rejected, Max. Limit is extended to 1.5

Designing Criteria

Design BV = 3-10 BV/hrMaximum Bed Depth = 1.5 mMinimum Bed Depth = 1.2 mDesign velocity = 8-12 m/hrResin capacity (as F) = 1-4 gm per ltResin capacity (as F) = 1-4 gm per lt

Regeneration

Regeneration Chemical = CaCl2 / Al2SO4

Regeneration Level( 100 %) = 150 gpl

Percentage of Regenerating Percentage of Regenerating Chemical in Water( F Free) = 10 % (Al2SO4)

25 % (CaCl2 )REGENERATION MODE = CRREGENERANT TEMPERATURE = 30 Deg C

Advantage of SST 60 resin

1. SST 60 is NSF/ FDA/ Halal approved resin2. SST 60(in Al form) is highly F selective resin.3. Purolite SST 60 (in Al form) does not required any pre and

post pH correction.4. Purolite SST 60 (in Al form) can operate in wide range of pH4. Purolite SST 60 (in Al form) can operate in wide range of pH5. Purolite SST 60 (in Al form ) can operate in wide range of

Temperature ( max 120 deg C)6. Purolite SST 60 (in Al form) is having higher bead strength

so there are less chances of contanimination in Potable Order.

Why SST60 is so Efficient

• High regeneration efficiency

• Faster Kinetics

Page 12February 2, 2013

• Better elution of contaminants

• Reduced Rinse water

•Low regeneration level and conc.
