Nitrates, primarily originating from agricultural runoff and industrial processes, can contaminate water sources and pose serious health risks when consumed. Nitrate reduction filters utilise specialised resins which reduce nitrate levels in order to meet safe drinking water standards.
The significance of nitrate reduction filters is not limited to safeguarding health but also extends to environmental preservation. By reducing nitrate levels in water, these filters mitigate the adverse effects of nitrate pollution on aquatic ecosystems and help protect the quality of our natural water bodies. Additionally, nitrate reduction filters can be integrated into various water treatment systems, including point-of-use and point-of-entry solutions.
Clack duplex filters feature a dual design, allowing for continuous water filtration. Regeneration will take place when the unit lacks the capacity to sustain filtration for the upcoming 24 hours, leading to cost savings in terms of salt consumption.
