Advantages: 1. Ferric Contaminants Reduction: 80% ~ 90% 2. Silica Reduction: 70% ~ 90% 3. COD Reduction: ~ 50% 4. Microorganism Reduction: ~ 100% 5. Turbidity:<0.1 NTU 6. SDI: < 2 7. Stable/constant product water quality

Results: 1. Stable/reliable operation 2. Longer life-time of RO membranes 3. Less RO cleaning, less chemical

consumption 4. Lower RO operating pressure, less energy 5. Lower life-cycle cost

How to reduce your

chemical cost?

Remove micro organisms in your systems

mechanically with UF!

Remove the SS in your system continuously in cooling

towers and reservoirs with UF!

Which will improve heat transfer and increase process

efficiencies- Right?

Reduced risk of Legionella in the cooling area

52

Question.. When last did you test and evaluated filter products?

By changing media from PP to GF, increase life by 24%

Determined the exact PSD of the process? Will extend

the life, it block prematurely.

Dual filtration extends life of fine filters and save a

huge amount of money

Sand and self-cleaning filters does not work, it

is hugely inefficient.
