Application of Copper-Zinc Alloy in Water Treatment

2018-09-11
Copper-zinc alloy, also known as brass, has many excellent properties. The application of copper-zinc alloy has a long history, and it is an indispensable modern engineering material in modern society. With the rapid development of human beings into science and technology, the application of copper-zinc alloy filter materials in water treatment has also expanded into new fields.

Adding other trace elements to the copper-zinc alloy can act as a descaling and anti-scaling agent. Copper-zinc alloys have the following effects in water treatment:
(1) The copper-zinc alloy can reduce the concentration of residual chlorine, dissolved oxygen and soluble heavy metal ions in the water through the oxidation-reduction reaction, thereby reducing the corrosion of the metal pipe wall;
(2) It changes the crystal structure of formed scale by adjusting water quality parameters, and changes from calcite scale to needle stick scale. The combination of aragonite scale and heat exchange wall is weak and easy to be washed away by water flow;
(3) The moment of contact between copper-zinc alloy and water can greatly change the oxidation-reduction potential of water at the contact interface, not only destroying the cell wall of microorganisms, but also inhibiting the growth and reproduction of microorganisms, reducing scale and heat transfer. Strength of wall bonding;
(4) Copper-zinc alloy causes the solid phase particles to be in a state of suspension and dispersion, suppressing the generation of wax, scale and corrosion.
 
Because copper-zinc alloy has high efficiency, good stability, long service life, low cost, simple maintenance, no pollution, no energy loss, etc. in the water treatment, these years in the central air conditioning system, industrial heat exchanger system boiler water treatment The systems, reverse osmosis pretreatment systems, and fields such as anti-wax, anti-scaling, and anti-corrosion systems in oil fields have been greatly promoted and transformed, and may have important effects.
