General-purpose ceramic filters

We present ceramic filters of new generation. It is important that with the help of these filters you can purify a wide number of liquids and gases from mechanical impurities. 

It is also important that cost of new ceramic filters is much less in comparison with the one of conventional ceramic filters.

The advantages of ceramic filters of new generation are as follow:

  • high gas liquid permeability,

  • possibility of 100% regeneration,

  • improved chemical resistance,

  • improved mechanical strength,

  • improved high temperature resistance,

  • high electric conductivity.

As a result it provides longer operation period and general-purpose use of articles.

Ceramic filters are made as hollow cylindric elements (pipes). Their individual characteristics depend upon the purpose and the construction of filtering device in which they are installed.

Such pieces can be used:

  • in oil-and-chemical industry for purification of fuels, oils and other oil products, as well as running electric heaters;

  • in gas industry for purification of natural gas;

  • in chemical industry for purification of air, vapor, acid solutions, alkali, as working elements for capillary drying of high-concentrated suspensions;

  • in metallurgy for purification of gas effluents and industrial waste waters;

  • in heat power industry as gas burness, for purification of natural gar before burning;

  • in public utilities for purification of drinking water;

  • in space equipment as capillary pump.

all regeneration methods from impurities are possible

7-year experience of the use of ceramic filtering pipes showed that our filters are reliable and hold all their properties till present. Besides, on the base of ceramic pipes semi-automated stations for purification and disinfection of water from natural sources for household and drinking purposes with productivity of 0.2 - 0.6 m3/hour were constructed. They supply of small villages and enterprises.
