Ozone Pre-Treatment Systems

Enhanced Filtration with Ozone

The MS Filter system is the ultimate pre-oxidation/biological filtration process. Ozonation oxidizes organic molecules such as colour, taste and odour compounds, and generally reduces the organic loading of waters and therefore reduces precursors to disinfection by-products.

Ozone addition prior to slow sand filtration can increase the efficiency of TOC removal by about 35 percent (EPA Guidance Manual, Alternative Disinfectants and Oxidants, April 1999). Currently operating MS Filter systems with preozonation are removing colour from as high as 120 TCU to less than 5 TCU without the need for a GAC contactor.

Benefits of Ozone

Slow Sand Filtration has provided safe potable water to millions of consumers for many decades but as knowledge and regulations have advanced it has become clear that the removal of organics has become a treatment priority to minimize the formation of disinfection by-products. Traditional Slow Sand Filters have a good but limited ability to remove natural and synthetic organics. Ozonation breaks down these relatively stable dissolved organic molecules to more biologically digestible forms allowing the biological process to effectively remove them. An independent study ranked pre-oxidation/biological filtration as second only to Reverse Osmosis for removal of synthetic 'Compounds of Emerging Concern' (CEC). The MS Filter system is the ultimate pre-oxidation/biological filtration process.

Ozone Retrofits

MS Filter now offers the ozone pre-treatment process as a separate package system that can be retrofitted into existing slow sand filtration facilities to significantly reduce organics and disinfection byproducts.

Ozone’s excellent disinfection and oxidation qualities have rendered it instrumental in many drinking water and wastewater applications.

Ozonation is also effective at removing iron and manganese and as an aid to coagulation.

MS Filter can assess your needs and evaluate whether adding ozone to your existing drinking water or wastewater system could benefit your community.
