calls for tender, drinking water treatment that uses no chemicals, water treatment that uses no chemicals, drinking water Dagua offers a unique value proposition for local and international communities with large-scale drinking water treatment projects (from 5,000 to 500,000 m3/day). Delivering highly effective water purification and disinfection, Dagua’s ozone-membrane process occupies up to 40% less space than conventional coagulation systems. With coagulation eliminated from the treatment process, the DaguaFlo solution has a clear edge over the competition! To meet the needs of small- and medium-sized communities (500 to 5,000 m3/day), Dagua designs and manufactures prefabricated treatment plants that purify water to the most stringent quality standards. Available with or without housing, they are installed as a single unit between the source of the water to be treated and the distribution network. The plants are designed according to the specific parameters of a project and allow for an anticipated increase in water flow. Dagua also offers ozone generators for municipal and corporate applications such as the treatment of effluent, cleaning and the disinfection of industrial processes. Dagua's ozone generators represent an innovative solution for the replacement of chemical cleaners. Dagua also manufactures turnkey ozonation systems, with housing, measuring instruments and air and oxygen generation included. Our ultra-compact systems include a PLC for remote operation and monitoring. Drawing on years of R&D experience, Dagua has developed a patented process for the cleaning of ultrafiltration membranes using ozone microbubble technology. Ozone microbubbles are finely diluted in water to deeply clean capillaries and prevent membrane fouling. Dislodging accumulated solids without chemical cleansers, this process delivers significant cost savings. With this innovative technology, frequent downtimes for chemical cleanings are a thing of the past as well.

Calls for Tender

Are you interested in asking Dagua to submit a budget proposal for a drinking water treatment project that uses no chemicals for a community, a company or a client? If so, please send us the following information so that we can properly assess your needs and get to know you better:
  1. Your corporate profile : An Internet site describing your business activities would be appreciated. If you do not have one, explain to us in a few lines the nature and scope of the business you are involved in.


  2. Application : What need does your request for a budget proposal pertain to? Is it a commercial, industrial, municipal, residential, military or other application? Please specify. Indicate also the source of the water to be treated:
    1. Surface water
    2. Groundwater
    3. Groundwater under surface water influence

  3. The main design parameters: Please specify the following:
    1. Desired water flow (in cubic meters per day).
    2. Interest in acquiring a treatment plant with a building or one that is simply secured to a platform to be housed inside an existing building. In the latter case, please specify the dimensions of the available facility:

      o Total surface area ____________ m2
      o Length ____________ m
      o Width ____________ m
      o Height ____________ m

    3. Interest in a mobile unit delivered on wheels and designed for frequent moves
    4. Outside temperature range :
    5. o Minimum temperature _______°C
      o Maximum temperature _______°C

    6. Effluent disposal capacity : __________ m3/day

  4. A profile of the raw water to be treated: Forward to us the parameters of the chemical composition of the water to be treated so that our experts can evaluate the complexity of the treatment in question. Please refer to the following link for a list of the parameters we ask you to submit to let us prepare a reliable assessment of your needs.

    Description of the water profile (PDF)

  5. Temperature range of water to be treated :
    1. Annual average: _______°C
    2. Minimum temperature: _______°C
    3. Maximum temperature: _______°C


  6. Treatment standards to be met: The extensiveness of the filtered water treatment standards to be met directly affects the technical design criteria and, consequently, the price of a treatment plant. A thorough analysis of these parameters (see the table on the previous link) will enable us to propose technology that is technically and economically effective in response to your specific needs. Should you not have any standards specific to your environment, we suggest you use the US EPA reference to come up with a brief evaluation of your requirements.

  7. Power availability: Since power requirements account for the lion’s share of the operating costs of a treatment plant, we would like to know about the availability of a power source for your application. Can you count on a reliable and consistent power system, or do you anticipate having to use generators occasionally or frequently? What are the characteristics of the available power supply?

    1. Voltage : _______volts
    2. Max. amperage: _______amperes
    3. Number of phases: ________phases
    4. Frequency: ________Hz

  8. Operation and maintenance of the plant: Please specify whether local resources are available to operate and occasionally maintain the plant or whether Dagua will be called on to do so.


  9. Site location and access: Indicate location for plant delivery and describe available site access (air, land and sea).


  10. Delivery date: We ask that you indicate the approximate delivery timetable desired for the commissioning and operation of the plant.


  11. Financing structure: We would appreciate knowing whether your project is private or public (governmental) in nature and if the financing structure has been confirmed.

Please note that Dagua will not provide any detailed specifications or total or partial price lists before having had an opportunity to thoroughly analyze the required information. We believe that foresight and safety go hand in hand when it comes to drinking water and public health.

Once the aforementioned information has been submitted to rfon@gmail.com and validated by Dagua, please allow 72 hours for an initial estimate to be sent to you. We look forward to serving you soon!
