The application of direct electric voltage to wastewater in industrial wastewater treatment plants to neutralize colloidal particles, resulting in the electrochemical coagulation of particles and metals. The rectifier must not only provide the electrical current required for the process under the harsh environmental conditions of the industrial wastewater treatment plant, but also have the capacity to provide more than its rated current for a limited time. Khazartransformer, by considering this capability along with the quality of direct current and the operator's limited presence in the wastewater treatment plant, designs, manufactures, installs, and commissions the most suitable rectifiers for your project.
