Ozone Treatments
Ozone is an oxidizing agent used to remove organic or metallic contaminants and as a sterilizing agent for microorganisms.
Given its unique properties, ozone plays a central role in the treatment of industrial wastewater.
Why choose ozone for drinking water and wastewater treatment
Advanced oxidation for drinking water and wastewater
SIAD has studied and applied ozone to water treatment since the early 1990s, integrating laboratory research, industrial ozonizers and proprietary dosing systems. One of the most powerful natural oxidants, second only to fluorine, ozone acts with rapid kinetics and fully converts back into oxygen, leaving no persistent residues in drinking water, municipal and industrial wastewater, and sludge.
Speed
Faster disinfection than chlorine compounds
Recovery
Possibility of recovering residual oxygen
Purity
No persistent residue in treated water
Drinking water
Drinking water: rapid disinfection, independent of pH and ammonia
Ozone offers a higher disinfection speed than chlorine compounds, maintaining its effectiveness regardless of water pH and the presence of ammonia. Even in the event of overdosing, it does not generate harmful by-products for humans, such as AOX and THM, and improves the organoleptic qualities of water without leaving organic or inorganic residues.
Wastewater
Wastewater: effective on a broad spectrum of refractory pollutants
In addition to traditional final disinfection, ozone removes surfactants and detergents, refractory COD, cyanides, phenols, nitrites, sulfites and sulfides, colors, MTBE, BTEX, emerging micropollutants (EMPs, POPs) and complexing agents. It is also used to increase the BOD/COD ratio of effluents resistant to subsequent biological treatment.
Ozone
Ozone production from oxygen and recovery of residual O2
Thanks to the new patent developed under the Green Deal programme, SIAD optimizes water purification: ozone is generated from oxygen, which may be self-produced through VPSA technology, and instead of dispersing excess gas, it is recovered to feed the biological sections of the plant, drastically reducing energy consumption.
SIAD ozone-based technologies and processes
SIAD covers the entire ozone value chain for water treatment: from on-site production starting from O₂, to the high-efficiency MIXFLO3 reactor, through to ozonolysis applications on the water line and sludge line. All supported by the Environmental Biology and Chemistry Laboratory.
Ozone for drinking water: metal removal and advanced disinfection
Ozone is the traditional benchmark for drinking water treatment. It removes organic and metallic pollutants such as iron and manganese and acts as a biocide with a high disinfection rate, independently of pH and ammonia, without generating the harmful substances typical of chlorine.
Ozone for wastewater: tertiary treatment and EMP reduction
In finishing processes at municipal, industrial and consortium wastewater treatment plants, ozone breaks down emerging micropollutants of pharmaceutical and cosmetic origin, refractory COD, colors and complex compounds. SIAD has also consolidated its know-how through the PerFORM Water 2030 programme.
On-site generation: from O₂ to O₃ with industrial ozonizers
SIAD collaborates with leading ozonizer manufacturers for on-site ozone production from oxygen, with concentrations of 6-15% by weight and specific consumption of 6.5-13 kWh/kg O₃. Capacity ranges from a few grams/hour up to 200 kg/h, depending on the process.
