Whole House Nitrate Reduction Systems

Clack Valve Platform

Your customers expect their water to be clear and clean throughout the home.  When properly sized nitrate removal systems reduce nitrates to acceptable mcl levels.  The EPA has set maximum contaminant levels (mcl) for nitrate as NO3-1 at 10.0 mg/L (as N) and Nitrite as NO2-1 at 1.0 mg/L (as N).  While it is possible to use Type I and II anion exchange resins, the safest treatment for point of entry (POE) drinking water is nitrate selective ion exchange resin.

Pre-treatment of the water with a softener and or iron removal systems may be required ahead of the nitrate system.  Considering potential health concerns proper sizing of nitrate systems is imperative.  We recommend a full water analysis including total anions prior to application.

Sources of Nitrate

• Human Sewage – malfunctioning septic systems
• Livestock manure runoff
• Fertilizers
• Erosion of natural deposits

Nitrate Health Effects

• Methemoglobinemia (blue baby syndrome)
• Most potential health effects are seen in infants under 6 months.

Treatment Methods

Whole house treatment is strongly recommended although other treatment methods are available for point use – reverse osmosis and distillation.
