RO pre-treatment catalyst

  

RO pre-treatment catalyst is specific designed for RO pre-treatment which are consisted of phase conversion coagulant and phase conversion polymer, and can be condensed, all water contaminants of impurities, solids, suspended solids, oil/grease, hardness, smell, odor, bacteria, algae, organic matter, chemical, toxic chemical, heavy metal being transformed into granular separative silt sedimentation, and purified the water clear rapidly and effectively, and also availably applied at all kind of RO pre-treatment water to do simple, fast, economic, effective and practical RO pre-treatment purification treatment and application

1. the function and effect of RO pre-treatment catalyst:

   a. low dosage:100~200 ppm,

       low SS/BOD/COD removing rate:80~95%

   b. high dosage:300~400 ppm

       high SS/BOD/COD removing rate:98~99.5%

   c. 1~3 minute reaction times: more reaction times for high

       SS/BOD/COD purification effect

2. BOD/COD removing rate:85~99.5%

3. SS/hardness/heavy metal removing rate: 85~99.5%

4. bacteria, algae, biomatter removing rate: 95~99.5%

5. oil, emulsion, colloids removing rate: 95~99.5%

6. NH4, P, N, VOC removing rate: 85~99%

7. biotoxin (microcystin), chemical toxin (trihalomethanes) removing rate: 85~99%

8. the silt density index of biofoulant, organic foulant, inorganic foulant, silica foulant and the

  scalant of oil, colloid, carbonate, phosphate, silicate removing rate: 85~99%

9. eliminate and clean the silt density index and scalant being accumulated formed cake and

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

10. eliminate wasted silt production, treatment fee and toxins to do effective wasted silt and

   toxicity elimination and reduction treatment
