Request for suggestions for my new publication

Published on by in Academic

Dear Fellow Professionals,

My new book is under preparation under title "Biotechnology of Wastewater Treatment". The emphasis has been given on the role of Microorganisms in Activated Sludge process and how these can be used as indicator for the stability of treatment process. This book will be helpful for STP operators, student and researchers. 

I would like to welcome the suggestion on topics which you think are essential to be included in this publication.

  4. DEAR MAMTA TOMAR,

    I think that the book can be  more useful if it  will  be  supplemented with sludge treatment and processing technologies into useful products, fuel and /or energy.

    1. thanks for your suggestions. Actually my intention is to emphasize on the role of microbes in biological process in detail because I have seen the people struggling to understand a sudden change in treatment process due to several reasons and in finding a proper solution to control the situation

  5. Dear Ms Tomar, as it would be the book for STP operation personnel I would strongly recommend to include the part with the most popular failures on WWTPs like floating sludge or similar, unexpected biological changes etc and ways how that could be resolved as that is usually the problem for average and small size objects without their own bio-engineer

  6. Dear Ms Tomar,

    Please look into the following points too while planning the book:

    1. Reduction of Total Dissolved Solids

    2. Reduction of Volatile Solids

    3. Reduction of Total Suspended Solids

    4. Reduction of COD

    5. Reduction of BOD

    6. Elimination of Ecolii

    7. Elimination of Nitrates (Nitrification- Denitrification through bacterial action)

    8. Elimination of Phosphates 

    9. Reduction of Turbidity

  8. Sorry didn't mean to do it twice

     

  9. Dear Ms Tomar, I have been working with a variety of waste water treatment plants for for over 25 years.  I would start with the importance of aeration in the transfer of oxygen into the water and the removal of Carbon dioxide.  Pure oxygen resulting in pH levels of 0.5 to 1 units lower changing the population dynamics.  How the use of jet mix/ venturi systems cause the break up of bacterial floc interfering with settlement.  How surface aeration systems in a round tank does transfer air into the water but does not fully mix the tank resulting in anaerobic conditions developing in parts of the tank.  The difference between fine-bubble aeration and coarse air in oxygen transfer into the water and its importance in phosphate removal. 

    The importance of anoxic selectors in the absorption of nutrients especially phosphate, prior to aeration.  The importance of ammonia oxidising bacteria in the control of ammonia and how they do not grow on organic materials but fix their carbon from carbonate in the water.

    The importance of protozoa and metazoa in controlling the size of the floc and allow the transfer of oxygen and enhance bacterial settlement.

    You will need to describe the different types of system called activated sludge as well as the supposed advantages and disadvantages of fixed and mobile media. You will also need to differentiate between plants using membrane separation rather than settlement tanks. This is before you even start on the micro-organisms themselves.

    Once you have started this then you can describe the range of organisms involved under normal conditions.  Start up of an effluent plant.  How and when bacteria will be required to be added to an activated sludge plant.  The presence of filamentous forms of bacteria.  Conditions under which bacterial flocs weaken and form zoogleal growth.  Bacterial foam formation.  I could go on.

  10. Congratulations on bringing microbes to the forefront of treating waste. Hundreds of methods I am sure. As a suggestion only please begin with and focus on the need to include natures #1 microbial cleaner. The archaea species.  No other methods, machines, or chemicals comes close to it. Details upon request.  Good luck. 

  11. TSS,COD control,diffusion of oxygen into slurry water are some of the vital points to emphasize.

  12. 1. microbial biofilm associations used to treat WW in constructed wetlands are largely undescribed.

    2. Micro-fungi and mycelium -- descriptions, maintenance(?) and how-to support their development for specific contaminants are largely undescribed.

    These are among the research and design priorities at Wetlands Work, Ltd.

     

  13. Dear Mrs. Tomar,

     I think that the emerging contaminants issue has become a significant problem, and it's a reality that actual conventional STPs and WWTPs do not completely remove these pollutants, so it's necessary to look for new alternatives for treatment as well as search for different configurations for existing biological treatment systems in order to effectively remove these substances. I am not an operator, but I suspect that there are many books out there that are already focused on everyday problems at WWTP (foaming, sludge bulking, low sedimentability...), so, as one colleague mentioned above, you've got to make a difference with respect to other WW engineering books.

    1. Hi Ubaldo, thanks for your suggestions. Actually microbes have a special power to assimilate organic pollutants of wastewater but we don't know how to give them appropriate friendly environment to help them in their growth & propagation. My book will cover this gap and show how we can help them to grow & give the required treatment. Secondly it's not an engineering book more emphasis has been given on microbiology related to WW treatment.

  14. As an operations manager, I would love a 2 part book. The 1st part deal with detailed trouble shooting and the 2nd part explains the technical aspects behind d the issues.

    There are lots of books in this field so you need to find your point of difference.

  15. Dear MT.

    Great to note your interest.

    I have been doing WWT plants on natural remediation applying Dewats mode of treatment on MSW waste water.

    It has 3 stages and in the last tertiary process, phyto remediation is done .

    This phasexwould have your interest . Pl indicate if you require data.

    But to come to 3rd process , one needs to go thro the 2 processes.

    Well wishes.

    Prof Ajit Seshadri .

  16. I would say include bioaugmentation in the book. It is becoming more and more used to start-up, restart and stabalize the operation of treatment plants and is also used to tackle specific problems like filamentous problems, sludge mass reduction and fat, oil and grease accumulation.

  18. The usual candidates: foaming / bulking, identification and what can be done for control.

     

    Protozoa as health indicators.

  19. I would start on the important division of  steps: pretreatment, biology treatment, settlers, sludge treatment.

    For biology treatment dividing to technology types: CASS, SBR, MBR, IFAS etc.
