Problems solved by technology

Ordinary micro-electrolytic fillers are made of reduced iron powder, activated carbon, binders, pore-forming agents and other raw materials. Wastewater needs to be treated in a specific acidic or alkaline environment, and it is easy to passivate and harden, cannot be activated and regenerated, and has a short service life; , Ordinary micro-electrolytic fillers have defects such as small specific surface area, small porosity, poor adsorption performance, and poor impact load resistance. Effectiveness and Efficiency
