Galaxies-cite

Galaxies-cite is selected, natural, hard, clean anthracite an is used in single-layer or in dual media filters for purification of all kind of water including portable, waste, process and swimming-pool water

 

Galaxies-bitumen

    Galaxies-bitumen is selected, natural, hard, clean Bitumen an is used in single-layer or in dual media filters for purification of all kind of water including portable, waste, process and swimming-pool water.

 

Galaxies-coconut

   Galaxies-coconut is selected, natural, hard, clean crushed coconut an is used in single-layer or in dual media filters for purification of all kind of water including portable, waste, process and swimming-pool water.

 

Galaxies-carb       

Galaxies-carb is a granulated activated carbon. The raw material is hard coal. A special treatment is applied prior to steam activation.

 

Galaxies-sand

   Galaxies-sand is a natural silica sand, through an elaborate refining process, together with constant quality control, elevated to top quality media- free of clay, dust, organic matter or any other contamination, thus meeting Indian and all international standards.

 

Galaxies-gravel

Galaxies-gravel is a natural, and free of clay, dust, organic matter or any other contamination
Commonly three or four layers of i.e. different sizes are filled in under the galaxies-sand to prevent losses of fine media through the nozzle/laterals pipe system and to eventually distribute backwash media water and/or air.

Galaxies-cite - Technical Specifications
General

Galaxies-cite is selected, natural, hard, clean anthracite an is used in single-layer or in dual media filters for purification of all kind of water including portable, waste, process and swimming-pool water.
Applications

Filtration

  • For removal of suspended solids
  • Of surface-and well-water
  • Of coagulated water
  • To protect activated Carbon Filters, Ion-exchange and reverses osmosis Membranes
  • Of Swimming-pool water
  • Of condensate. Important: galaxies-cite will not release any SiO2 to the water.
  • Of waste water
  • Of mill scale-laden (recycle) water

Galaxies-gravel - Technical Specifications
General

Galaxies-gravel is a natural, and free of clay, dust, organic matter or any other contamination.
Commonly three or four layers of i.e. different sizes are filled in under the galaxies-sand to prevent losses of fine media through the nozzle/laterals pipe system and to eventually distribute backwash media water and/or air.

Applications
Support-layer
