Fluoride Reduction PreFilter with Casing
This Fluoride reduction Prefilter is beneficial to add to the UltraStream to increase Fluoride removal from your drinking water. The UltraStream will remove approx 80% fluoride, the fluoride pre-filter removes up to 75% and together they will remove up to 95% of the fluoride from your water.
Activated Alumina Crystal Fluoride Reduction filter 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).
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.
