The RO membrane defouling catalyst

RO membrane anti-fouling catalyst

RO membrane anti-fouling catalyst is specific designed for RO membrane anti-fouling cake and scale treatment which are consisted of RO membrane defoulant catalyst and descalant catalyst, and can be condensed and transformed the silt density index of biofoulant, organic foulant, inorganic foulant, silica foulant and the scalant contaminants of carbonate, phosphate, silicate, oil/grease, emulsion into high permeable granular silt as RO membrane auxiliary filter media to eliminate RO membrane cake & scale effect, extend RO membrane usage and expire, reduced RO membrane working pressure down to 10~12 kg/cm² operation, elevate RO membrane permeability, increase RO production capacity and BOD/COD removing rate to do high permeability, high production capacity, high BOD/COD removing rate, low investment, low treatment cost and expense, low working pressure, zero discharge, zero pollution, wastes & toxicity elimination and reduction, rapid recycle all the investment and treatment cost and expense to do high economic utility RO process treatment and application

[Feature]

1. low dosage:10~25 ppm treatment:

as RO membrane anti-scalant catalyst

2. normal dosage: 100~200 ppm treatment:

as RO membrane de-foulant and de-scalant catalyst

3. elevate RO membrane permeability up to 80~95%

4. increase RO production capacity up to 90~110%

of standard RO process treatment design

5. increase BOD/COD removing rate up to 85~99.5%

6. reduced RO working pressure down to 10~12 kg/cm²operation and save energy: 70~90%

7. condensed all the contaminants into granular separative silt to do zero discharge treatment

8. transformed the impermeable SDI and scalant foulant into the high permeability granular

silt as RO membrane auxiliary filter media

9. eliminated RO membrane clean, regeneration and replacement fee, wastewater discharge

treatment and electric fee to reduce down RO treatment cost and expense effectively

10. avoided, eliminated and cleaned the silt density index and scalant being caked and scaled

on the RO membrane to extend RO membrane usage and expire effectively
