Fluoride Removal Pre-Filter

The UltraStream will remove up to 78%-95% fluoride, the fluoride pre-filter removes up to 75%-80% and together they will remove up to 95%-99% of the fluoride from your water.

How it works

Activated Alumina* is manufactured from aluminium oxide** by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square metres/gram. The compound is used as a filter of fluoride, arsenic and selenium in drinking water.

Used in conjunction with a KDF-based filter (already in the UltraStream) will filter any possible activated alumina eluted from the fluoride filter.

*Activated Alumina is not made from  Aluminium.   This material will not harm those persons will Thyroid issues.

**Aluminium oxide (alumina; Al2O3), the same chemical substance as sapphire and ruby (but without the impurities that give those gems their colour).

Activated Alumina Crystal Fluoride Reduction filter

The material in this pre-filter removes fluoride through a chemical reaction with the media; thus the removal is not dependent on ion exchange*.

The filter contains specially processed Crystalline Activated Alumina to reduce fluoride in the source water.  The cartridges are designed to perform at slow controlled flow rates to ensure maximum performance by the media.

Cartridges contain a synthetic aluminium oxide that is specially processed to have a minimum of fines and other foreign matter.  The material removes fluoride through a chemical reaction with the media, thus the removal is not dependent on ion exchange.
The material has a uniform particle size similar to ion exchange resins. It has minimal shrinkage or swelling and low-pressure loss. It is physically stable and can be used over a wide pH range.

Fluoride is removed by a chemical reaction with the media. The process is flow and pH-sensitive. The best results are obtained when the flow is limited to 1gpm/cu.ft and the pH is held at 5.5. Higher flows and higher or lower pH causes a loss of capacity.

It is estimated that at 1ppm fluoride in the water the filter will cope with approx 1800L before needing change.

Additionally, the filter is excellent for removing arsenic and lead.

Arsenic removal – is very pH sensitive and capacity decreases rapidly when the pH is below 5.5 or above 6.  Arsenic removal is also affected by temperature and by the TDS (total dissolved solids) of the feed water. Increasing temperature increases capacity while increasing TDS decreases capacity.

Dissolved lead is absorbed by the media.  Capacity for lead is at least 0.4lb per cu.ft while maintaining greater than 98 percent lead removal. This process is not dramatically affected by flow rate, temperature or TDS. However, pH should be maintained above 6.0 as lead removal drops under acidic conditions and below 10 as lead precipitates under basic conditions.

* Ion Exchange filters are often presented as fluoride filters. Unfortunately, although they do remove up to 60% of the fluoride from drinking water, they store it and once ion exchange reduces through usage, all the stored fluoride will be re-released into the water.
