The PEFT Cell uses a highly efficient and cost-effective electrochemical process to disinfect water supplies, with low electricity costs and no chemical additives. The cell's mode of action is summarised below: - Production of chlorine from the chloride ions naturally present in water, which inactivates pathogens. - Production of a high voltage electrice field (from low applied voltage), which disrupts the cell membranes of pathogens and enhances the lethality of chlorine. The PEFT Cell has a modular design and multiple modules can be connected to treat greater flows, meaning that the technology can be adapted to a range of applications.
WaikatoLink are seeking alternative applications for the PEFT Cell, where the value of the technology may be in the following areas: eliminating use of chemicals for disinfection; effective disinfection in low chlorine environments; effective operation in turbid environments.
The PEFT Cell technology is currently being developed for the following applications:
