Water intended for human consumption must meet strict quality standards to ensure it is safe and wholesome. Water treatment is a process that removes physical, chemical and microbiological contaminants, ensuring that the water complies with the limits set by current regulations. Depending on the quality of the raw water, various treatment technologies may be used.
Key Technologies for Water Treatment
1️⃣ Pre-treatment and filtration
- Screens and sand traps: remove debris and coarse solids.
- Sand or multi-media filters: remove turbidity, suspended solids and fine particles.
2️⃣ Chemical-physical treatments
- Coagulation and flocculation: these processes cause suspended particles to clump together, making them easier to remove.
- Chemical oxidation (using chlorine, potassium permanganate, ozone): breaks down organic substances and iron/manganese.
3️⃣ Removal of Specific Contaminants
- Activated carbon: absorbs organic compounds, pesticides, PFAS and chlorinated solvents.
- Ion exchangers and zeolites: they remove heavy metals such as lead, arsenic and chromium.
- Reverse osmosis or nanofiltration membranes: these remove dissolved salts, nitrates, fluorides and emerging contaminants.
4️⃣ Final Disinfection
- Chlorination: maintains an active residual to protect the water supply from bacterial contamination.
- UV light or ozone: they destroy viruses, bacteria and protozoa without producing harmful by-products.
Benefits of Advanced Water Treatment
- Complete elimination of pathogens and chemical contaminants.
- Water safe for human consumption, in compliance with current regulations.
- The treatment can be adapted to the characteristics of the raw water.
- Modular and scalable technologies for small and large-scale applications.
The integration of multiple technologies ensures effective and sustainable water treatment, providing high-quality water for domestic use and public distribution.
