Why testing is essential
Because nitrate is invisible, a laboratory result is needed to quantify it. The treatment decision should also consider other ions, total dissolved solids, hardness and the volume of water that must be treated.
Ion exchange
Nitrate-selective ion exchange can be used in appropriate applications. Resin capacity, competing ions, regeneration requirements and waste brine management need to be included in the design.
Reverse osmosis
RO can reduce nitrate together with many other dissolved ions. Pretreatment, recovery, storage and concentrate disposal still need to be engineered around the source water and required output.
Treat the right volume
In some properties, drinking and cooking water represent only a fraction of total demand. The most practical design may therefore differ from a whole-property system. HydroGrid considers the use case before sizing equipment.

Frequently asked questions
Practical answers to common questions we receive when planning this type of water project.
Can boiling remove nitrate?
No. Boiling does not provide a practical nitrate-removal method and can concentrate dissolved substances as water evaporates.
What technologies can reduce nitrate?
Depending on the water and application, treatment may include nitrate-selective ion exchange or reverse osmosis. Design should be based on laboratory results and competing ions.
Should nitrate be tested again after treatment?
Yes. Where nitrate reduction is a treatment objective, post-treatment testing is the appropriate way to verify performance.
Need a system designed around your actual water?
Send HydroGrid your location, water source, intended use, approximate daily demand and any existing laboratory report. We can then identify the information needed before a treatment proposal is prepared.
