1. To reduse phenol  by Ozone, is more benefit than filter by carbon.

    

2. Yes, fenton process, or ozone followed by GAC would be simplest method.

3. Bacta Cult - Aerobic is a Bio culture formulated by Amalgam Biotech, India. Our Bacteria strains are acclimatized for Phenol and can Bio degrade it.  Amalgam Biotech is one of the leading manufacturers of Bio culture in India. Please get in touch rajesh@amalgambiotech.com

4. The most practical approach, given you have a reaction vessel with enough retention time, would be using potassium permanganate oxidation.  This has been successfully demonstrated in a continuous stream of 800 gpm at almost the exact concentrations that you have.  Hope this helps.

   1. Great!

      But what is the suitable retention time and the initial dose ?

      1. Fentons will work, but way to many steps and you need more reaction vessels as compared to KMnO4 treatment.  We found it economically more viable as well.

      2. That requires bench work to get an idea of your background demand for the oxidant.  There are othe reduced species in the wastestream I am sure.  Vary dosing based on oxidant to phenol and run several jars over time collecting and analyzing to get your best options.

6. Hi Mohammed,

   The Fenton process is the simplest method and one of the most efficient methods for the to oxidation and removal of phenol  and phenolic compounds from aqueous solution. The process can oxidize phenol, phenolic compounds and reduce their concentration to below 0.05 ppm if the addition of iron is not an issue for you. The concentration of Fe(II) required would be low and on the order of 1 -2 ppm.

   The Ozone-Peroxide (O3-H2O2) would also be very efficient and the treatment costs would be relatively low providing that access to an ozone generator is not an issue, however, the capital costs would be much more than the Fenton process.

   Good luck

   1. Thank you.

      But what is the initial dose to use ?

7. Technologies including the conventional methods such as activated carbon adsorption, solvent extraction and advanced technologies such as electro‐Fenton method, membrane‐based separation method, photocatalysis and so on, which have all been successfully used for removal of phenolic compounds from water.

   1. Photocatalytic degradation of phenolic compounds.

   2. Ozonation

   3. Extraction method(Among the techniques used for removal of phenolics from water is extraction using polar organic solvents. The extraction method of phenolics removal from wastewater can be categorised as liquid‐liquid extraction and solid phase extraction.)

    

   (a) The liquid‐liquid extraction method

   (b) Solid phase extraction method

   4. Biological method

   5. Adsorption

   6. Membrane‐based separation method

   7. Electro‐Fenton method

   8. Adsorption and ion exchange

    

    

8. Are you referring to phenol as phenolic compounds or just phenol?  If impurity is pure phenol, solvent extraction followed by aerobic bio-degradation will work very well.

   If there are phenolic compounds, then you may opt for oxidising the water with ozone followed by adsorption. 

   For doing actual assessment, will need detailed chemistry of influent and flowrate etc. 

9. The treatment used is ozone to oxidise the aromatic structure and GAC (Granular Activated Carbon) to absorb the residual ozone and hydrocabon debris  Greg Turner.

10. We supply a unique adsorption and oxidation system that works very effectively on Phenol, can I suggest that you take a look at our video 

    https://www.youtube.com/watch?v=-A1ApyGHgEM 

    Benefits are - no treatment chemicals, no sludge production and no need for regeneration of media just some electricity.

    Our website www.arviatechnology.com has some examples of Phenol removal.

    If it is of interest, please revert to me and I will gladly provide more info

    1. Interesting!

       Kindly check ur mail.

        

11. We designed a phenol removal treatment plant for a 30 m3/day leachate treatment system using ozone with a 1 - 2 hour detention time.  Bench scale test to determine ozone feed rate and detention time. You can also remove biologically.  Ozone was the simplest answer.
