What are the advantages of ceramic filter material compared with quartz sand and activated carbon?
By Zhao from Onlyzone,a manufacturer of water treatment bio ceramic ball filter media in China.
Ceramic filter materials are increasingly used in water treatment due to their excellent physical and chemical properties, including alkaline filter materials, hydrogen-rich filter materials, mineralized filter materials, scale inhibition, Fluoride Removal, chlorine removal, etc.
The ubiquitous problems of quartz sand and activated carbon are that the specific surface area is small, the porosity is really small, and the pollution interception capacity is limited. In water treatment projects, quartz sand, activated carbon and other materials are traditionally used as filter materials in the filtration process. For a long time, there have been defects such as low sewage interception capacity, short operation cycle, and large water consumption. The comprehensive technical benefits are generally not high.
Ceramic filter material is a new type of artificial filter material researched and developed in view of the shortcomings of the above-mentioned filter material. It is a kind of spherical filter material produced by mud, aging, forming, drying, firing and other processes. Its surface is hard and its interior is microporous. More importantly, the new ceramic filter material has a very low dissolved salt content in water, which fully meets the national drinking water hygiene standards.
The new ceramic filter material not only has the characteristics of corrosion resistance, oxidation resistance, non-toxicity, high hardness, etc., but also has a large porosity and a huge specific surface area, which is conducive to intercepting and adsorbing impurities in water.
In addition, the specific gravity, permeability coefficient and porosity of ceramic filter material can be adjusted according to the ratio of raw materials and production process, so it can meet the requirements of raw water quality for filter material.
In our filtration technology, the ceramic filter material used in the production is sintered at a higher temperature, the specific surface area of the filter material is larger, the filtering effect and the ability to hold dirt are stronger. The pore size and rough surface, in the process of accumulation, the pore size and slits of the filter micropores on each microlayer surface are different, so that the filter pores and slits are not straight lines but curved lines, making it have the characteristics of depth filtration or container filtration Entering the pores, in each part, the size of the pores and gaps is changed, so that the flow rate of the medium also changes, coupled with the irregular changes in the pores and gaps, so that a part of the impurities smaller than the pore size are intercepted and adsorbed by the side wall, and the adsorption The impurities further increase the surface area and structural complexity of the filter material, so that finer impurities can be adsorbed.
Therefore, the new ceramic filter material is more and more widely used in water treatment, and is widely used in water treatment filters, separation and purification of gas, liquid and solid, or as a support for biological carriers and ultrafiltration membranes.
