Fluoride removal
Due to high presence of fluorides in wastewater from several industrial sectors, that can not be removed with conventional chemical or physical treatments, in Servyeco we have developed a new innovative range of product which reduce fluoride content down to the technical and legal requirements.
The reactivity of the fluoride ion makes its removal from effluents very complicated. One of the main techniques used for its treatment is based on the use of calcium compounds (usually calcium hydroxide). Calcium fluoride is obtained and collected in filter bags. However, it presents a great number of disadvantages such as low efficiency in total elimination of fluorides and generation of very bulky and bad-dewatered sludge.
Searching for more efficient alternative to solve the fluoride presence in industrial wastewaters, Servyeco has developed ECOFLUOR series with the following advantages:
Sectors:
This series of products offer solutions for the next sectors (among others):
ECOFLUOR Series products obtain a removal rate between values 53%-83% in automotive sector with initial doses of 10-100 ppm.
Treatment:
1000 ppm FeCl3 (pH=8,5) + 320 ppm Calcium hydroxide (pH=10,5) + 1000 ppm Fluoride Removal + 6 ppm ECOPOL AS 100.
With the product ECOFLUOR B70 we can improve the fluoride elimination percentage by 19%, reaching a level of 96% of removal.
