What’s Aquxite Cleaner?
Cooling water treatment device for Circulation system through producing and supplying functional ceramics.
Background of its development
The problem with the use of a cooling tower
- 1. Cleaning of cooling towers requires hard work under the poor conditions.
- full of sludge, microbe and mineral deposition.
- 2. These foreign matters sometime block discharge openings.
- 3. Bacteria or Legionella bacillus can scatter giving neighbors a trouble.
- 4. Throwing sterilizer accelerates on the other hand corrosion of the equipment.
- 5. Mineral deposition in the heat-exchanger pushes up electricity cost.
There are drug formula and non-chemical formula of the system at the conservation of the cooling tower,
The above-mentioned problems resolution in bulk in the non chemical can without equipment,
And the experience was also troubled in steelworks working age itself, because there was a user needs, was crossing to the development.
Mechanism of Water Purifying
Scale dissolution / prevention mechanism
Equilibrium is needed.
Water quality deterioration causes CO2 defficiency resulting CaCO3 deposition.
As reduction effect by ceramics, Ca(CO3)2 dissolves making Ca(HCO3)2,
then equilibrium is maintained.
Cu ion leaching untied with the above reduction environment has anti-bacteria effect.
