With the aim of confirming that the treatment performance witnessed on the bench test transfers well into real-life situations, the NQ 3680-910 standard’s certification programme requires field audits each year. These audits involve an analysis of a sample of treated water to evaluate the technology’s level of treatment. At the same time, we gather valuable information regarding the efficiency of System O)) technology.
For example, the analysis of the sampled water during the 2021 audits revealed that in 90% of the cases, a much greater reduction than required of fecal coliforms was observed. This indicates that System O)) solutions greatly exceed that standard’s requirements regarding disinfection of wastewater for isolated dwellings at the secondary and advanced secondary treatment level, and this, in a totally passive manner.
The presence of fecal coliforms in water rejected into the environment can contaminate our sources of drinking water. It is reassuring to know that, even where disinfection is not required, System O)) solutions offer this additional protection.
