Ceramic Filter Media

Biological ceramsite filter media is a kind of granular water treatment filter media,appearance: black-brown spherical.The filter media has the characteristics of high mechanical strength, scouring resistance, abrasion resistance, stable physical and chemical properties, etc. At the same time, due to its rich microporous, rough surface, large specific surface area, long service life, corrosion resistance, good adsorption performance, particle uniformity, density is appropriate, not easy to caking plate, small amount of loss.Therefore, the intercepting ability is strong, the hanging film efficiency is high, but also conducive to microbial growth, reproduction, can effectively remove organic matter, suspended and nitrogen and phosphorus in the water.

Lightness is one of the most important of the many good properties of terra cotta, and the main reason why it can replace heavy gravel. The internal structure of ceramic granules is characterized by fine honeycomb micropores. These micropores are closed rather than connected. It is formed as a result of gases being encapsulated into the shell, which is the main reason for the lightness of the grains.

Scope of Application

1: Industrial wastewater and domestic cited water treatment, industrial circulating water treatment:

2: sewage (waste) water, water depth treatment and reuse treatment, swimming pool water treatment:

3: Treatment of micropollutants (ammonia and nitrogen) in feed water, pre-treatment system for high purity preparation;

4: Circulating water treatment in the production process of steel rolling and continuous casting;

5: Biological carriers for BAFs and oily wastewater.

Lightweight shale ceramic filter media is a new type of biofilm carrier filler with the advantages of light weight, large specific surface area and strong adsorption capacity. It is suitable for various types of filter tanks.Compared with quartz sand, the specific surface area is 2-3 times that of quartz sand of the same volume, and the porosity is 1.3-2.0 times that of quartz sand. Compared with sand filtration, the average filtration speed is high (20-25m/h), water production is large, filtration cycle is long, rinsing frequency is small, and rinsing intensity is low. Appearance: reddish brown or blackish gray granular.

Product Characteristics

1. Small specific gravity, high mechanical strength, punch and wear resistance, energy saving, good biological stability, chemical stability and thermodynamic stability.

2. Due to the rough surface, rich microporous structure, specific surface area, so the interception capacity is strong, high efficiency of hanging film, and Favorable for microbial growth and reproduction, high biomass.

3. Strong resistance to shock load, low temperature resistance, easy to hang the membrane, fast startup, low energy consumption for backwashing.

Scope of Application

Ideal for filtration of acidic, medium and alkaline water.
