Water Treatment
1. Description
Ceramic grain filters are made of refined pottery clays added with certain modifiers, and processed of grinding, mixing, shaping and high temperature sintering. They do not contain any substances that harmful to people or environment. They are hard and rough in surface, porous inside the structure, and have the advantages of high mechanical strength large specific surface area and porosity, When used in water treatment, they behave a activated surface property, a great amount of pollutant entrapment, less water head loss in the filter bed, lower consumption of back-flush water, stable in chemical and gbiologic property, and long service life. Ceramic grain filters is a new and efficient filter material to increase the water yield, upgrade the water quality, and save chemicals and energy.
