Marine WWTP Bidding

Am bidding on Marine WWTP near Port Sudan at the Red Sea. 

There is an old plant of 14 cum/day a designed to serve forty people only.

Now the number increase and plant capacity is too low and tertiary treatment bypassed. A new plant to serve 120 people is required and daily capacity is determined it is 40 cum per day.

The attached document is full of details. Please refer to the document and help me to present a competitive offer.
 

Thanks

    Ma solution alternative permet de supprimer les parties de votre projet de 2 à 4.3 ce qui constitue une sérieuse économie financière.

    A ce jour votre dispositif d'assainissement et votre projet, produit 1 kg/jour  de Matière Fécale qui sera transformé sur le site terminal de gestion des eaux usées  en 1kilogramme/jour de rédisus  boueux de Matière fécale.

    La solution alternative produit 1 kilogramme/jour de Matière fécale, mais ZERO gramme de résidus boueux  sur le site de gestion des eaux usées.

    J'ai fait la même proposition d'urbanisme à l'entité territoriale d'une ville de Tunisie de 180 000 habitants.

    My alternative solution removes parts of your project from 2 to 4.3 which is a serious financial economy.

    To date your sanitation device and your project, produces 1 kg/day of fecal matter that will be processed at the terminal Wastewater Management site in 1kilogramme/day of muddy rédisus of fecal matter.

    The alternative solution produces 1 kg/day of fecal matter, but ZERO gram of muddy residues at the wastewater management site.

    I made the same planning proposal to the territorial entity of a city of Tunisia of 180 000 inhabitants.

     

  3. I'll be very happy to see your alternative option .

     

    Thanks .

      Afin de vous faire une proposition chiffrée il me faut des renseignements sur l'infrastructure de gestion collective du plan d'urbanisme actuel.

      Vous pouvez me communiquez tout cela sur mon adresse Email lyseconcept@necourrier.com 

      In order to make you an encrypted proposal, I need information about the collective management infrastructure of the current urban plan.

      You can give me all this on my email address lyseconcept@necourrier.com 

  4. Bonjour Elmalieh Ibrahim

    Est il possible de vous soumettre  une proposition différente du projet  détaillé en pièce jointe? 

    Une solution plus simple, beaucoup plus économique et biologique. 

     

    Hello Elmalieh Ibrahim

    Is it possibile to submit a different proposal to the detailed project as an attachment? 

    A simpler, much more economical and organic solution. 

  5. Dear Mr. Ibrahim,

    Waste water generation is 333 l/person/day. Its is too high.

    The recommended water consumption is in the range of 90 to 150 LPCD.

    You can use our Patented Deep Tanks Aeration system which has low energy and area foot print.

    If space is available Zero Energy Natural Treatment Process can be used.

    Please write fo further details on sarafrv@virajenvirozing.com

  6. Hi Eng. Ibrahim,

    This has got reference to the question  you had posted on the Water Network.

    We were not able to access the details you had referred to.

    To  enable us offer our input do send the information to wemcons@gmail.com

  7. Dear Mr Elmalieh,

    I didn’t received the plant flow sheet but I hope that my considerations can help you.

    Two questions:

    1)     Why so big holding tank (30 hours HRT!)? In any case, the holding tank must be aerated.

    2)     Why the screen after the holding tank?

    Considering your very low flow and organic load, I recommend SBR plant instead continuous activated sludge plant.

    To have very simple and efficient plant I propose:

    -Screen

    -Pumps

    -SBR (low charged, composed by two aeration tank 35 m3 each)

    -Blowers

    -Holding tank and chlorination reactors V: 10 m3 with mixer

    -Pumps

    -Pressure sand filter

    -Sand dry bed.

    I know that my design is very generic because I don’t know your local and specific requirements so please use it as an idea.

    Best regards

  8. It is a good project.

    I think you could think in an MBBR that is more efficient nad easier to operate than than an activated sludge system.

    Could it be quoted to the final user?

    Can ssome other technologies be used for this in this treatment?
