Abstract
This development corresponds to a system with electronic components for the treatment of high-concentration fluids or solutions or suspensions with solutes, such as wastewater treatment, obtaining valuable elements that are part of a fluid, seawater desalination, among other processes. The system comprises electrodes, tank, solid-state electronic device, a system management algorithm, and an optional solids removal device. This development also intends to protect a fluid or solution treatment procedure that generally involves two joint or sequential stages, whereby a dynamic electro-coagulation takes places first, followed by dynamic electro-flocculation, in order to separate liquids from dissolved solids or solutes from a solution.
