Microbiological Growth Removal

Published on by in Academic

How can I remove the microbiological growth from effluent treatment plant (ETP) treated water & RO permeate water?

  2. Whatever treatment process is selected to inhibit microbiological regrowth, the easy to use, rapid microbial detector Speedy Breedy is an ideal instrument to demonstrate the log kill achieved (accurate to 1 cfu E.coli in 12 hours). www.SpeedyBreedy.com

  3. Good suggestions have been given by several experts. I would like to add the following:-

    1. Find what the microbiological growth consists of and in what way it is helpful or problematic.
    2. Chlorination solves some problems and creates others. Use of ozone or ultra-violet rays would be more advisable. These methods are needed mainly to eliminate pathogens.
    3. Microstraining can be very effective if the biological growth is due to algae, which can be harvested with advantage.

    1. Hello Again it is necessary that these algae do not bathe in a liquid bio chemical at a high oxidation rate. This is the case for all collective sanitation effluents. The seaweed will saturate chemical pollution and die, as does the much more insensitive bacteria in a polluted environment. Sewage sludge contains more than 8% of dead bacteria. A heresy when we know that in nature a dead bacterium does not exist. But it is nice to see that people think that there is a super bacterium that survives without oxygen, in putrefying mud.

      But why does this super bacteria not manage to muddy the mud?

  4. you can prevent biological growth in ETP & R.O. effluent , by  chlorination disinfection process , for ETP , the chlorine dose is such that , the residual chlorine after 30 min contact time is 3 to 5 ppm and for R.O 0.5 to 1.00 ppm

  5. If you are referring to water from a settlement tank, then there is a residual BOD on which organisms such as Sphaerotilus natans can grow.  So it depends on the use of the water.  The water can be pumped through a filter containing AFM media (Dryden Aqua) but avoid sand because it will become colonised by bacteria, which AFM does not.  Depending on the use, the water can be chlorinated, brominated, chlorine dioxide treated and then re-used.  RO permeate will contain trace nutrients and bacteria will grow through membranes (don't believe sales promises that no bacteria can get through their membranes).  For a high purity water, we treated the water with UV immediately after the RO then fed a tank where it was chlorinated although chlorine dioxide could have been used in its place.  Although this is general advice, really the actual application would need to be investigated and recommendations made on the actual application.

  8. If I have understood the question correctly the problem is to control the increase in microbial counts in ETP treated water (presumably disinfected) and RO permeate. The development of colonies is a natural process that will occur as long as there is a source of the organisms accessing the water and nutrient in the water for them. The question that needs to be asked is are they a problem that we need to do something about? If so then either some disinfection process with a residual such as chlorine or chloramine for longer effect is needed or UV radiation at the point of use.

  9. Hi,

    I understand the point of view of Jean but microbiology can cause corrosion (MIC) but also can be limited by specific site discharge limit. It is why certainly the question is asked. Remove completly microbology is not possible, limit his developement well! The treatment to limit microbiological growth will be different according to:

    • Process parameters (flow, temperature, volume, etc.);
    • Environmental discharge limit (chlorine, AOX, EOX, etc..);
    • Type of microbiological organism that you will limit/remove;
    • Water quality.

    A lot of different ways can be used but you have to do a techico-economical study to find an adapted solution (ozone, chlorine, ClO2, paracetic acid, bromine, chloramine, etc...)

  10. Hi,

    Fully agree with lyseconcept jean Marius  in all terms. On the other hand if you do have a reason to remove remaining micorbiological factors from RO effulent, or any effluent, the most efficient (kill all) type solution is application of ozone. If you want an economic and effective solution and your target is disinfection but sterilization, application of UV is the answer. Of course, there are plenty of criteria you need to check (or have them checked by experts). Both technologies are advantageous: there are no need of extra chemicals applied, practically no harmful by-products are produced, these solutions deliver good efficiency and also the economics are good. If interested, pls visit sites of trustful manufacturers.

    Best regards,

  11. Google search will give you a required answer. It is too simple to be answered.

  12. jean has the best and most professional answer and explanation.  But if you were to focus your question to "how do we get rid of the pathogenic micro organisms", the answer is the RNA microbial group called Archaea. No pathogenic microbes can exist within their matrix.

  13. Use 0.05 PPM TwinOxide in the RO inlet, to control biofouling and use 0.2 PPM TwinOxide for the treated water. (www.twinoxide.us)

  14. Hello

    In -biology- there is no microbiological growth, there is the Life of the Living. The microorganisms are renewed every 20 minutes by sissiparity.

    If there were no bacteria in the wild, we would be dead. They are useful, necessary, obligatory, etc. To incite an action of deterioration of this Alive is a crime against humanity.

    These bacteria develop constantly. In water, in the air, in wastewater-biological- in nature, in our food, on our body, in our body there are. And fortunately since they are the ones who organize our LIFE. Man today is like the bacteria he wants to destroy, eliminate, he destroys.

    By wanting to destroy microorganisms wastewater you are removing the only natural tool that eliminates excrement. By this action you produce a phenomenal amount of excrement sludge that nobody has any solution to eliminate it.

    In biological sanitation with biotechnology lyseconcept fecal matter disappears between 12/15 days.

    How has the man-technic-been able to arrive at this stage to believe that he could be superior to Nature?

    The heresy of this post is that, the waste water arriving at the station, are mud. Chemical impregnated mud in which bacteria die and no longer do their job

     

  15. We will assist you in eradicating microbial from treated ETP water as well as RO permeate water. We are a company based at Mumbai but have effective solutions in the field for such typical solutions using Purojal DW. 

    This solution is already adopted by a leading hospital for their soft water that is post RO as they were having microbiological contamination issues. Our system has been installed and is operating 24x7x365 days a year. After installation of the system the microbiological issue has been eradicated.

    1. Bonjour 

      C'est pour cela que les hopitaux développement à une vitesse grand V les maladies nosocomiales. Plus ces hopitaux appliquent cette procédure, plus ces maladies se pérennisent. Tu vas à l'hopital pour un petit soucis, tu en ressort mort. Vive l'éradication des mircos organismes.

      Hello

      This is why hospitals are developing at a high rate of V nosocomial diseases. The more these hospitals apply this procedure, the longer these diseases become. You go to the hospital for a little worry, you come out dead. Long live the eradication of the microcosms.
