Community Water Fluoridation​

FILTEC have developed tailored community water fluoridation solutions to provide safe and cost-effective fluoride dosing into drinking water.

Does your community water supply require fluoride dosing?

When considering a community water fluoridation system, you want to be sure your supplier can support you from specification right through to service and support. FILTEC’s water fluoridation systems meet New Zealand drinking water and chemical safety standards.

New Zealand water sources typically have low concentrations of natural fluoride. Fluoridation is the process of adding the micronutrient fluorine to drinking water to achieve a safe and targeted concentration level in treated water. Fluoride dosing is the most effective and efficient way to help prevent dental caries, such as tooth decay, in communities receiving a reticulated water supply.

Which water fluoridation solution should you use?

Community water fluoridation - fluoride into drinking water

The most widely used water fluoridation solution is Fluorosilicic acid (HFA). Due to its scalability we highly recommend HFA for large water treatment plants.

Our FILTEC HFA Fluoride Dosing System is a safe and cost-effective method of dosing fluoride into drinking water. Using Fluorosilicic acid (HFA) this Fluoride dosing system has four size options to meet the requirements of a population of up to 150,000 people (45MLD).

All components are supplied with safety in mind and are all HFA compatible. The dosing system’s instrumentation provides continuous monitoring of the fluoride levels and is linked to a control system that accurately maintains the fluoride in the drinking water.

Fluoride AquaDOSE for Small Communities

The Fluoride AquaDOSE offers a dependable and cost-efficient way to add fluoride to drinking water, while fully complying with the New Zealand drinking water and fluoride dosing code of practice.

Specially designed to meet the unique needs of small communities with populations of up to 10,000 people. Our innovative solution ensures the optimal fluoridation of water. 

Community water fluoridation - sodium fluoride dosing

Sodium Fluoride (NaF)

Sodium fluoride is a dry salt additive, typically used in small water treatment systems, dissolved into a solution before being added to water.

Our team can advise you if sodium fluoride is a suitable community water fluoridation method to use at your water treatment plant. Get in touch with us today for a no obligation chat about your fluoridation needs.

Sodium Fluorosilicate (SFS)

Sodium silicofluoride is fed into water by means of mechanical dry feeders equipped with solution tanks. This solutions is typically used in medium sized water treatment systems.

Our team can advise you if sodium fluorosilicate is the right fluoride dosing solution for your water treatment plant. Get in touch with us today for a no obligation chat about your fluoridation needs.

Clutha District Council - Various Sites

Sodium Fluoride Dosing System

FILTEC have recently delivered sodium fluoride dosing systems to four water treatment plant sites for the Clutha District Council. The four sites are located in the Southeast tip of New Zealand’s South Island.

FILTEC supplied the fluoride dosing equipment as well as the mechanical and electrical installation and commissioning services to the Council. For two of the sites, in Tapanui and Kaitangata, FILTEC also provided 10′ containers to house the fluoridation systems. The dosing systems come equipped with special loaders to ensure easy and dust-free loading of Sodium Fluoride into the saturator tank.

Waverly Water Treatment Plant

Sodium Fluoride Dosing System

Waverly is a small town located in South Taranaki on the West side of New Zealand’s North Island, with an estimated population of 860. To address the water quality issues (including E. coli contamination) and comply with New Zealand Drinking Water Standards FILTEC provided full water treatment services, including water fluoridation.

FILTEC delivered a sodium fluoride dosing facility as part of the build of a new water treatment plant for South Taranaki District Council. The sodium fluoride is delivered in 25kg bags to the site and stored in the Fluoride room. Consumption is around 2.6 25kg bags per month, with on hand storage never exceeding 10 bags.
