Watercore demineralised water systems, based on reverse osmosis (RO) plus electrodeionization (EDI) are capable of delivering consistent ultrapure water for commercial and industrial application with very little maintenance compared to traditional resin demineralisation processes.
Watercore demineralisation systems are designed to be part of commercial or industrial ultrapure quality water systems, delivering an average conductivity of 10-17 Megohm.cm.
Ultrapure water is water that has been purified in a way that not only suspended particles have been filtered but also any dissolved component has also been removed. This way demineralised water only contains H20 molecules, hence ultrapure water conductivity is about 0,055 uS/cm or 18,2 MOhm.
A typical water demineralisation system will contain pre-treatment, reverse osmosis (RO), electrodeionization (EDI) and an ultrapure water tank. Polishing, UV disinfection and a recirculation system can be included as options.
Watercore water purification method delivers the highest purity and is different to other systems in the market as the last purification stage is based on EDI technology. EDI is more effective and cost efficient method than distillation or ion exchange purification and results offer a more consistent demineralised water,
The whole system will typically be enclosed and will include PLC monitoring and control.
Watercore water demineralisation systems possess many benefits over tradicional ion exchange systems:
Hardness can cause scaling in both, the RO and EDI components. Minimising Calcium and Magnesium concentration in the source water will extend the time between services.
Organic compounds (TOC) are adsorbed by reverse osmosis membranes and EDI surfaces. This generates fouling of the active parts of both systems reducing their efficiency.
Suspended solids (TSS) and colloids are responsible for membranes and EDI fouling. Fouling increases the pressure drop across the modules and reduces the whole system efficiency.
Iron and active metals reduce the capacity of the resins and membranes, even in sub-ppm concentrations.
Chlorine and other oxidising agents attack the RO membranes and the EDI surfaces resulting in reduced capacity.
