Water Treatment Power Supply ApplicationWaste water treatmentWaste water treatment processes require DC power for producing electric fields,these processes rely on DC power supplies, electrolytic water treatment power supply, also referred to as rectifiers, as a critical device in the treatment of water to convert available AC to DC, as DC power is not readily available. With the power supply outputs connected to the water enclosure's electrodes, control of the power supply is critical to ensure process repeatability and operational safety. Front touch panel indicators and self diagnostics eases system setup and troubleshooting.Electrodeionization (EDI)Electrodeionization is a chemical-free water-treatment process that uses electrodes to ionize water molecules to separate dissolved ions from the water. A DC power is used in conjunction with electrochemical cells to provide the electricmagnetic field to separate the ionized species from the feed water. EDI is often used in applications requiring ultrapure water, such as pharmaceutical, semiconductor manufacuring, or other industrial processes.ElectrolysisHydrogen generation via electrolysis of water relies on water being split into individual components and then introducing electrons to form hydrogen gas. Water reacts at the anode for an oxidation reaction, resulting in positively charge hydrogen ions and oxygen gas. The hydrogen ions then combine with electrons at the cathode, introduced from an external circuit, to form usable hydrogen gas. A high-current DC power supply is connected to the electrodes to provide the external current necessary to produce hydrogen in volume.Why Green Power power source rectifier?Support automatic output polarity reversalas short as every 5 seconds for waste water treatment process.Build for high reliability, professional and experienced electrical, mechanical design and software programming, reliable materials and components, strict quality control process, PCB board reliability testing and full load aging testing.
