Fluoridation
Fluoridation of drinking water remains the most significant dental health program in New South Wales and Australia. The advantage of water fluoridation is that the entire community benefits from the preventative measure, regardless of age, socioeconomic level, educational achievement, individual motivation, or the availability of dentists.
Fluoride packages and installations have to meet strict guide lines. In New South Wales where ProMinent Australia have supplied more than 50 systems, there is a fluoride code, ‘Code of Practice for the fluoridation of Water Supplies Act 1957‘.This code was published by the Oral Health Branch of the Dept of Health and revised in April 2018. This code has also been accepted by other Australian states as the bench mark for fluoride installations.
Fluoride is available commercially in 3 different ways, 2 are powders the other a liquid. Each display different concentrations of available fluoride ions & solubility.
Powder
Sodium fluoride (NaF) - most expensive 44% by weight available fluoride ion (solubility is 4.0%)
Sodium Silicofluoride (Na2SiF6) - 60% by weight available fluoride ion (solubility = 0.4%)
Liquid
Hydrofluosilicic acid (H2SiF6) - liquid - 24% by weight available fluoride ion
ProMinent Australia is one of the market leaders when it comes to providing powder fluoride systems. We have many years of experience with sodium silicofluoride volumetric feed packages and with sodium fluoride saturator packages.
For the continuous monitoring of fluoride levels in water supplies, a ProMinent fluoride analyser is available with milliamp retransmit and alarms. The analyser is normally supplied as backboard mounted with temperature, fluoride and reference electrodes. A magnetic stirrer is also provided to assist with the single or two point calibration. Double validation monitoring is available.
