POREX^® Sand Bed Filters are designed for use in municipal and industrial water treatment facilities to minimize water flow resistance and prevent the loss of filtering media through the filter plate, while uniform distribution of back flush provides improved bed regeneration and long system life in municipal and industrial water treatment facilities. Porex innovated a new approach for filter-bed support media that can be automatically backwashed. In the design, filtration media such as carbon and sand are supported above an underlying filter bed composed of porous polyethylene (PE) plastic plates that function like a "false floor", allowing the filtered water to flow through. Customized tooling and manufacturing processes create a system that is durable, efficient, and easy to install.
