We are often asked to comment on the waste of backwash and rinse water from our Iron Max well water filters. Actually there is no wasted water in the classic sense. The Iron Max iron filter does not add any chemicals to the water so the water going to drain has pretty much the same chemistry as the source water. Some constituents such as iron and manganese are in higher concentrations, but the water is still usable. Our RDWS-NS Sediment Filters fall into the same category where the backwash water simply contains excess sediment accumulated by the filter.
Not All Iron Filter Components Are Created or Tested Equal - How Is The Iron Max Different?
The Iron Max uses NSF 61 filter media:
NSF/ANSI Standard 61, Drinking Water System Components - Health Effects establishes minimum health effect requirements for the chemical contaminants and impurities that may be indirectly imparted to drinking water. The standard provides the criteria used to evaluate the public health safety of materials, components, filter media, products, or systems that contact drinking water, drinking water chemicals, or both.
Filter tank complies with certified by the Water Quality Association (WQA) to NSF/ANSI Std. 44 for material safety and structural integrity requirements and Std. 372 for low lead compliance.
Control valve complies with NSF/ANSI Standard 372 for Lead Free Compliance
With such certifications and very little interference with your raw water, the water discharged during the backwash cycle can easily be turned into a useful water source. During the backwashing process of our Iron Max system, accumulated iron and manganese are washed away from the specialized media and goes out the drain tube. Our customers have the freedom to take this drain to wherever they'd like it to go, whether that's simply to an approved drain source or rerouted for use on plants or other watering purposes that don't mind a little extra iron or manganese.
