1. Take a look at the Arvia ODC for a chemical free treatment solution.

2. Hydrogen Peroxide is the best solution.

   Executive can assist

3. Despite the fact that bacteria removal is stated by many to be a very easy design task, many utilities around the world are a testament to the difficulty of removing Sulphur and or Sulphate reducing microbes.

   Its not a straight forward answer as there are a range of indirect and direct  methods available for removal of microbes and each process has numerous available options.   In addition,

   1. the volumes you are treating will impact on the best economic choice.
   2. the best process will depend on the type of microbes but as you have sea water it is likely to be the Sulphate reducing not Sulphur reducing type.

   A water treatment consultant can only assist if you are prepared to advise the design basis of your desalination plants pre treatment.  

   Perhaps a direct contact will be best as quantity of information required will overload any discussion forum limit.  stewart@slswaterfilters.com.au

4. Nano-Aeration and filtration accompanied by bio-remediation is a start

5. As you intend to use this water for desalination, you could cascade it in an aerated/oxigenated filter (sand/gravel) with 2 or more stages.
   For potable water, you will have to treat the filter cascades regularely, e. g. by using peroxides.

6. Some Bioremediation products having strict anaerobic bacteria having capacity to create food and nutrients scarcity for SRB and completely kill them its very simple and cost effective process which is successfully used by us 

7. Reducing SBR-Sulfur  bacteria we have to dealkaniser in brackish water treatment if rotten egg smell is there.In SWRO plant we have to use antifoulant/scalant and micron filtration is best method which we adopted,Regards

8. I would try chlorine or hydrogen peroxide then filter using an AFM filter.  AFM is active filtration media and removes bacteria, it can filter down to 1 micron.

9. Sulfate reducing bacteria are one of the toughest bacteria and are known to resist many antimicrobial compounds. However, best chance is to create unfavourable environment like more oxygen and / or chlorine into the system. Aeration and chlorination will help as you are producing possibly potable water?

10. Aeration or use of chlorine/Chlorine dioxide/Hypo

11. Antone;  Just add oxygen.  Sulphur loving bacteria do not generally survive in oxic environments.
