Nitrates Whole House Removal Filter
This is a whole property water filter to remove nitrates from your water supply.
The filter has a max flow rate of 20 litres per minute which is within the parameters of most properties (See how to check your flow rate)
If you have a higher flow rate please contact us for a customised quote
How Does it Work?
The media in the softener removes nitrates using chloride ions found in the sodium chloride softener salt. These ions are replaced by nitrate ions already present in the water.
When the resin reaches its capacity, it will be regenerated by immersing it in a brine solution within the cabinet basin. This reverses the chemical reaction and loads up the resin with chloride ions, preparing it for exchange once again.
Upon depleting all chloride ions, the unit will regenerate and drain away any trapped nitrates.
This process is similar to a salt softener, except that instead of using chloride ions, sodium ions are used.
The unit comes preloaded with an appropriate amount of nitrates media. You will just need to add salt.
Inside the middle of the unit you will see a flap that opens. You simply fill this compartment up with salt. As it gets used up the compartment empties. Typically the salt will need replenishing every 2-4 weeks.
It's best to check it every couple of weeks and fill up the brine compartment fully.
There is no indicator for the nitrates media so we would suggest taking a sample every year to make sure that the water is still satisfactory. If not, then change the media.
Benefits
- Effectively eliminates Nitrates
- Provides protection against scale build-up on expensive heating elements
- Requires minimal salt consumption for operation
What You Get
Exactly how much of the nitrates is removed will vary depending on factors such as the local water chemistry, the extent of the contamination and the life stage of the filter.
Important note: To ensure totally filtered drinking and cooking water fit for human consumption you should consider adding an additional point of use / under the sink Reverse Osmosis system in addition to, or instead of, this whole of property anti-nitrate filter.)
Replacement Parts / Ongoing Costs
Ongoing Costs for Salt Usage
The unit would work on a metered capacity rating so when it knows the media inside is expired, it would regenerate and make it reactive again to the incoming water.
Each regeneration would use 3.2kgs of salt.
So on average this unit would use around 9kgs of salt per week to remove the nitrates. (A cost of about £3 per week - much cheaper if you buy the salt in bulk).
Ongoing Costs for Nitrate Removal Media
Every 5 years or so the nitrate removal media itself would need replacing (Cost for this size unit would be about £597 at current rates).
The main unit filtration media should last you five years before it needs changing. Replacement media costs £597.

What Percentage of the Nitrates are Removed by the Whole House filter?
Nitrate resin when working correctly, and with the correct contact time (ie not exceeding the max flow rate), will remove around 90% of the nitrates.
The exact amount depends on variable factors like: your flow rate, local water chemistry, temperature etc.
Where to Install it
Typically a nitrate removal filter for the whole house would be installed before the water tank. (Almost any property accepting a private water supply will have a holding tank).
This is because the flow rate into a tank is much more constant - and slower - than on the outlet side, where the outflow will depend on how much water the property happens to be drawing from the tank.
The private water supply should almost certainly have an Ultraviolet filter aswell. (The UV would always go after the tank).
Electrical Power
These units operate with a standard 3 pin plug 240V
