ERA disc filter focused on multiple filtration grades, high effiency and large volume filtrationadvantage.We adopted Grooved Disc Design which is a combination of surface filtration anddepth filtration . The discs are in a fully compressed state, the upper disc is attached to thelower disc and the grooves between the faces intersect together to form an infinite number ofintercepting holes. When the water flows through, some larger particle impurities in the waterare intercepted on the outer surface of the disc.The water flows into the disc filter to form thefiltration of the water which reach a high effective filtration.
