Turning on a tap. An ordinary, everyday gesture. And yet, before it comes gushing from the tap, the water has been on a long journey. Tap water is not naturally drinkable, unlike commercially available mineral and spring water. It only becomes drinkable thanks to extensive physical and chemical treatments. The production of drinking water is a crucial issue for populations. SUEZ offers operators effective solutions to produce quality drinking water in sufficient quantities to meet the needs of both individuals and professionals.
Produce quality drinking water in sufficient quantities
Water is declared drinkable and can be distributed to consumers only when it meets well-defined quality parameters. It is, moreover, one of the most stringently controlled food products. It is subject to extreme vigilance at every stage of its journey, from collection to distribution.
The production of drinking water thus requires expertise in multiple technologies and processes as well as the ability to anticipate requirements, which involves precise knowledge of water resources. Available reserves of natural water include groundwater (water tables), standing or running surface water (lakes, rivers, etc.), and seawater. The implementation of a treatment system to produce water that is suitable for drinking depends on the quantity of water available, its quality (taking into account the possible variations), economic costs and environmental constraints.
Helping you implement appropriate solutions for drinking water production
Water resources are a determining factor in the implementation of an optimal drinking water production system. Through the design of treatment systems ranging from the traditional to the more sophisticated, we offer local authorities technical solutions that meet their sanitary quality requirements, whether for a village of several hundred inhabitants or for a major urban area.
How to design, build and operate a water treatment plant?
As both project manager and water treatment specialist, we take charge of all the stages involved in designing and building plants:
Entrust the turnkey construction of your treatment plant to our teams, who ensure the complete management of all of the construction stages:
- choosing the process and locations;
- establishing the price, managing purchasing;
- monitoring the construction site, assembling the equipment;
- commissioning the facilities.
To reconcile lack of space with reliability and robustness requirements, we have developed a range of compact units:
- Benefit from a complete water treatment process, from coagulation to disinfection.
- Facilitate operation thanks to straightforward equipment.
- Save time with our pre-assembled components for fast on-site installation.
As a builder, our profession is based on several fundamental principles:
- Improve the performance of your facilities.
- Guarantee the reliability of your infrastructures.
- Ensure the harmonious integration of your plant into its environment.
How to deal with emergencies
To produce water in emergency situations, or for occasional needs, SUEZ offers containers that integrate aquasource® NOMAD systems.
- Set up compact, stand-alone solutions that are easily transportable.
- Treat groundwater or water from rivers, lakes and dams, depending on the situation.
- Opt for short- or long-term leasing or purchase the systems, depending on your needs.
Respond effectively to sudden surges in demand, accidental pollution, natural disasters, etc.
Manage occasional needs, in the event of maintenance work, for example.
Produce anywhere from 250 to 3,400 m3/day.
Benefit from direct connection to the network and rapid start-up (2 days for installation and commissioning).
How to produce quality drinking water
We use specific treatments that allow for extracting a certain number of elements from water:
- Suspended solids and dissolved organic matter.
- Certain minerals (iron, manganese, arsenic, sulphates, etc.).
Desalination is another way of meeting the growing needs for both drinking and fresh water. It is also a responsible means of managing water resources:
- Benefit from reverse osmosis technology for high quality desalinated water.
- Keep investment and operating costs under control.
- Limit the environmental impact of producing drinking water through the use of renewable energies for the power supply of water treatment plants, as well as internal energy recovery and the dispersal of saline concentrates (brine) to protect flora and fauna.
Disinfection is the final stage of water treatment for the production of drinking water. It is critical because it:
- Removes all pathogenic microorganisms from the water.
- Guarantees the bacteriological quality of the water for the consumer thanks to the residual effect of the disinfection process.
- Choose the most appropriate disinfection system: chlorination, ozonation or UV radiation.
How to produce high quality water
Producing water with a lower limestone content is not just a question of user comfort. It is also a case of responding to environmental, economic and public health issues:
- Provide all users with fresh water at a reduced cost, identical for everyone thanks to collective carbonate removal.
- Limit discharges into the natural environment of detergents and anti-limescale products containing phosphates.
- Reduce energy consumption related to the scaling of household equipment and pipelines.
- Reduce the slow release in water of certain potentially toxic metals such as copper or lead, used to manufacture pipes.
- Begin with a preliminary diagnostic phase to adjust the carbonate removal technology to hardness reduction objectives, the quality of water resources, and the operating constraints of the water production plant.
- Opt for one of our collective carbonate removal solutions:
Softazur C, chemical carbonate removal by catalytic reactor.
DENSADEG®, carbonate removal by rapid physicochemical decanting and thickening of calcium carbonate crystals.
Physicochemical carbonate removal on ion exchange resins or nanofiltration membranes (or low-pressure reverse osmosis).
ERCA2, physical carbonate removal by electrocatalysis.
The change in our consumption patterns results in the appearance of new pollutants in water. Called “micropollutants”, these emerging pollutants are found in very low concentrations, by the micro or nanogram per litre:
- Effectively eliminate micropollutants thanks to our expertise in treatment processes.
- Optimise the choice of technology used depending on the characteristics of your water resource and its place in the treatment process: reverse osmosis or nanofiltration membrane filtration, ozonation or advanced oxidation, or adsorption on activated carbon.
