How to size an iron filter

Well Pump Flow Rate GPM

How To size Iron Filters?

ANSWER:
1) Amount of Iron (mg/L) to be removed
2) Well Pump Flow Rate (GPM)

Get Your Well Pump Flow Rate

Iron filters need a minimum of 5 gallons per minute (GPM) to backwash properly.

The larger the iron filter and the type of media being used dictates what is needed.

Some iron filters can require up to 20 GPM to backwash!

If you install an iron filter that is not back-washed properly, the filter media will get fouled and the system will not perform as it is designed.

If you do not know what your well pump will produce, then the first thing you need to do is run a simple test on your well pump to get an estimated well pump flow rate (GPM).

PROPER FILTER SIZING

What Filter Size?

In general, match your effective well pump flow rate to the backwash requirements to select the appropriate filter size.

Typical size is the 1.5 CUFT size, if your well pump can accommodate. An option is that you can also select a smaller size, if higher flow rates are not required.

IRON ISSUES

Excessive Iron In Your Home's Water?

That reddish - brown stains on your fixtures can not only be embarrassing to look at, but can also severely damage your plumbing. A quality iron filtration may be needed.

More About Excessive Iron Content in Water

An excessive iron problem is characterized by the appearance of that red-brown staining on bathroom fixtures, laundry and especially at the bottom of the toilet bowl.

In well water use, iron usually occurs in its ferrous state. This means that the water is clear when drawn but once exposed to air, the iron then changes into a ferric (oxidized) state.

The water turns red and forms insoluble “rust” particles. Staining can be caused by as little as 0.3 milligrams per liter (mg/L).

Depending on the iron concentration, there are several options to this aggravating iron problem. Selecting a dependable, quality iron filter will solve this issue.

Minimum Water Flow Rate Required:

The size of an iron filter or pH neutralizer system is dependent on the flow rate from your well pump.

Please check your flow rate to select the properly sized system.

Do not select a system that requires a higher flow rate.

💧 How to get your flow rate.

>>>> Get your Flow Rate:

  • Shut-off all faucets and make sure there is no running water.
  • Place a 5 gallon bucket by a hose bib (spigot) near your well pump.
  • Fully open the water hose bib until the well pump starts.
  • Then, start filling up your 5 gallon bucket, and time how many seconds it takes to fill it up.
  • Use the chart the following chart to get your flow rate.

Home size VS. WELL PUMP OUTPUT

Home Size & Bathrooms Are Secondary Factors When Sizing Iron Filters

This is due to your well pump's flow rate ability. Obviously, you can only use what your pump will give you.

Example:
If you have three showers running at the same time, you need about 7.5 GPM to operate them all and still have good water pressure.

But if your well pump only gives you 6 GPM, then you will not be able to operate all of those shower heads at the same time... not fun when shower water just drips out because of lack of water pressure.

So, if your well pump does 6 GPM, you options are limited to an iron filter that requires less then 6 GPM to meet proper backwash requirements.

Most iron filters that fit this criteria will typically have flow rates of 4 to 7 GPM.

So... Check Your Well Pump Flow Rate...

Other factors when Sizing Iron Filters

While the well pumps effective flow rate is crucial to properly sizing your iron filter, you want to also include and consider other water quality factors. A quality iron filter may help resolve other issues, but in some instance, additional filters may be required.

A quality iron filter can help remove excessive water minerals, typically:

  • Excessive Manganese
  • Excessive Hydrogen Sulfide/ Sulfur

Additional water filters may be required, commonly:

  • Acidic water

EXCESSIVE IRON CONTENT

More About Iron Issues

Excessive iron issues in your water is typically characterized by the ugly red or brown colored staining in your plumbing fixtures, sinks, toilets and laundry.

With well water, iron typically occurs in a ferrous state. That means, the flowing water typically looks clear.

However, once the water is exposed to the air, the iron transforms into a ferric/ oxidized state. The clear water will turn red or brown and insoluble “rust” type material will form.

Iron staining can be easily caused by as low as only 0.3 milligrams per liter (mg/L).

Depending on the iron content concentration, we have several solutions to this ugly and aggravating water problem.

A quality iron filter will filter out this excessive iron content.
