Ultrafiltration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron. Typically, ultrafiltration will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules. Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed.
Media Filtration is the most effective method for removal of suspended organic and inorganic solids from water. The media filters operate on the same basic principle as nature’s own ground water filtering process.
