Filtration materials of the ceramic particles

  The ceramic particles filtrating material is made in by choosing the excellent pottery clay and adding to the pore-forming material, bonding clay, through the processes as, ball grinding, sieving, compacting, and calcination. Its surface is hard, and there are many micro-pore pores among it. In addition, there are larger specific surface areas, higher porosity, and so on. During the water treatment, there are many characteristics for this product, such as, the stronger capacity of the pollutant entrapment, lower loss of the pressure head, longer filtration period, and smaller water consumption of reverse washing. It is a sort of novel filtrating material, which can increase the output of water, improve the quality of water, and save the energy consumption.

Molecular sieve
  The molecular sieve is a kind of the crystal aluminosilicate. Because there are even pore size and much higher specific surface areas, there are many of the excellent merits. (1) The selective absorption as the different size and shape of molecules, that is to say, it only absorbs those molecules of which the diameter is less than the pore size of molecular sieve. (2) To those smaller polar molecules and the unsaturated molecules, it has the property of selective absorption. The bigger the polarity is, and the higher the unsaturation is, the stronger property of the selective absorption is. (3) It has much stronger property of water sorption too. No matter in the situations of higher temperature, larger space velocity, or lower content of water it is, there is rather higher capacity of water sorption.
Now, there are many types of the molecular sieve, such as 3A, 4A, 5A, 10X, 13X, and Cu2+ etc., which can be produced by our company and applied to the industries.

9.Regenerating conditions of the molecular sieve
u The inlet temperature of the absorbing column: 250-320℃ ,the outlet temperature: ≧150℃。 
u The regenerating gas must be dried and can not contain the possible absorbing compositions of molecular sieve (Customers had better utilize the drying nitrogen). 
u Regenerating time: 3-4h under the constant temperature
u In general, the temperature of bed layer is reduced for the later utilization with the regenerating gas cooling.
10. Notice to order goods:
u For the molecular sieve is easy to absorb the moisture, it should be stored in the dry place, and avoid of exposing into the air. If the molecular sieve has absorbed the moisture and become wetted after laying aside for long term, it should be regenerated to use, and its property will not changed.
u For A and X type molecular sieve, if it is applied to in the solutions, the values of pH should be controlled in the range of 7~11, and the utilizing temperature should not exceed to 600℃, or it may loss the activity.
u If the special type of molecular sieve is needed, our company can research and develop for customers.
u If there is some difficulties during the utilization for customers, the technological staff of our company will provide the service on sites.
