Drinking water plants to produce high-quality water for everyone

In order to deliver water that complies with current regulations and according to the quality of your water resources (groundwater, spring, river and even sea) and your challenges (investment, operation, available surface area, expansion, etc.) we design and build water treatment systems dedicated to reducing the physical, chemical and organoleptic parameters (organic matter, turbidity, iron, manganese, sulphates, etc.) responsible in particular for taste and odour, as well as any micropollutants present (chromium, arsenic, PFAS, pesticides, pesticide metabolites, etc.).

To meet the challenges posed by the diversity of micropollutants to be treated and the complexity of the molecules identified in your water resources, we combine contributing processes (ultrafiltration, conventional oxidation, etc.) with dedicated processes:

• adsorption on powdered or granular activated carbon via our Pulsazur®, Carbazur®, Carbazur® Up and Carbazur® Simplex reactors
• advanced retention using nanofiltration membranes/low-pressure reverse osmosis (LPRO) for difficult water with several specific parameters to be corrected (hardness, pesticides, nitrates, micropollutants).
  

 

Finally, we guarantee consumer health and safety by eliminating microbiological parameters (viruses, bacteria and parasites) through perfect control of the clarification stage for surface water, as well as through disinfection (chlorination, ozonation, ultrafiltration, UV radiation), the final stage in the process of making water drinkable, regardless of its source.

To preserve your underground assets and enable all consumers to enjoy water that is more satisfying to use on a daily basis, we support you in implementing a centralised carbonate removal or collective softening process at your water production plant.

Although not directly harmful to health, excess limescale causes additional costs and inconvenience (discomfort for people with sensitive skin, scaling of equipment and pipes, purchase of cleaning products, excessive energy consumption, etc.). Excess limescale can be treated at drinking water production plants using our dedicated processes that target the ions responsible for water hardness.

Taking into account existing treatments, treatment objectives, the desired level of compactness, reagent costs and local solutions for the recovery of by-products (calcium fertiliser in agriculture, lime substitute in industry, manufacturing material for construction, etc.), we are able to select and implement the solution best suited to your needs.

• Chemical carbonate removal with our Densadeg® Decarbo recirculation reactor or our Softazur® C catalytic reactor
• Physico-chemical carbonate removal by ion exchange
• Physical carbonate removal by Low Pressure Reverse Osmosis (LPRO) or our ERCA² electrocatalytic reactor

Faced with increasing pressure on its water resources due to population growth and tourism, Macau has increased its water supply capacity from 390,000 to 520,000 m³/day thanks to a new treatment plant. This environmentally friendly facility, which has been awarded a Chinese label, uses our technologies to provide high-quality water to residents and businesses, while saving energy and reducing its carbon footprint.

This plant aims to meet growing demand and provide high-quality water from a degraded resource. With a production capacity of 40,000 m³/day, it uses innovative technologies to ensure enhanced health safety and reduce operating costs. The techniques include rapid flotation, pulsed activated carbon bed reactor, sand filtration and membrane ultrafiltration. The plant guarantees high-quality drinking water in terms of taste and health, while blending harmoniously into the landscape.
