The use of alumina ceramic valves in water treatment equipment

Performance advantages of alumina ceramic valves
Alumina ceramic valves have significant performance advantages in water treatment equipment, mainly reflected in the following aspects:

1. High hardness and wear resistance

• Alumina ceramics are extremely hard, with a Mohs hardness of 9, second only to diamond. This high hardness allows the valve to withstand high pressure and high flow rates during water treatment, while reducing wear and extending service life.
  Its wear resistance is 6-8 times that of traditional metal valves, and the surface wear rate is extremely low, ensuring long-term sealing and reliability.

1. Corrosion resistance

• Alumina ceramics are chemically stable and hardly react with common substances in water. Whether it is an acidic or alkaline water quality environment, alumina ceramic valves can remain stable and will not form an active check point that is conducive to scale adhesion due to chemical reactions like metal valves.

1. Scaling resistance

• The surface of alumina ceramic valves is extremely smooth, and the surface roughness is much lower than that of ordinary metal valves. This smooth surface makes it difficult for scale crystals to adhere and grow, thus effectively preventing scaling. Studies have shown that under the same water quality and operating conditions, the amount of scale adhesion on the surface of ordinary metal valves is 5-10 times that of alumina ceramic valves.

1. Good electrical insulation and high temperature stability

• Alumina ceramics have high electrical insulation (breakdown strength over 10 KV/mm) and excellent high temperature performance (maximum operating temperature up to 1650 ° C). This allows the valve to operate safely in high temperature environments and is suitable for a variety of complex water treatment processes.

The specific use of alumina ceramic valves in water treatment equipment
STEP 1 Prevent fouling

• Water treatment equipment is in contact with raw water containing various minerals for a long time, which is easy to form scale during heating and evaporation. The anti-scaling performance of alumina ceramic valves can effectively reduce scale adhesion, reduce equipment maintenance costs and energy consumption.
  For example, in a large industrial circulating water treatment system, after replacing the alumina ceramic valve plate, after a year of operation monitoring, the surface of the valve plate showed little signs of scaling, and the equipment operated stably.

1. Precise control of water flow

• Alumina ceramic valves contain multiple precision-machined apertures that enable precise control and filtration of water flow. This precise control capability is essential for filtration, purification, and distribution during water treatment.
  In the filtration and disinfection process of urban water plants, alumina ceramic valves can effectively avoid problems such as inaccurate addition of chemicals due to scaling, and ensure the stable production of tap water and the safety of water quality.

1. Increase equipment lifespan

• Due to the high hardness and wear resistance of alumina ceramic valves, their service life is much higher than that of traditional metal valves. This not only reduces the frequency of equipment replacement, but also reduces maintenance costs.
  After replacing the ceramic valve in a petrochemical enterprise, the compressor overhaul period was extended from 1.5 years to 4 years, and the single maintenance cost was reduced by 72%.

1. Suitable for a variety of water treatment scenarios
   Alumina ceramic valves are suitable for a variety of water treatment scenarios, including tap water treatment, industrial water reuse, seawater desalination, circulating cooling, and more.
   During the desalination process, alumina ceramic valves can effectively resist corrosive substances in seawater, ensuring long-term stable operation of the equipment.

Practical application case

1. Industrial circulating water treatment system

• A large industrial circulating water treatment system originally used metal valves, but after 3 months of operation, there was obvious scaling phenomenon, resulting in unstable water flow control and frequent equipment maintenance. After replacing with alumina ceramic valves, after a year of operation monitoring, there were almost no signs of scaling on the surface of the valves, the equipment operated stably, and the maintenance cost was greatly reduced.

1. Urban water works

• In the filtration and disinfection process of urban water plants, alumina ceramic valves perform well. Due to the addition of a variety of chemicals in the tap water treatment process, the corrosion resistance and anti-scaling performance of the valves are extremely high. After using alumina ceramic valves, problems such as inaccurate addition of chemicals due to scaling are effectively avoided, and the stable production of tap water and the safety of water quality are guaranteed.

Alumina ceramic valves have a wide range of application prospects in water treatment equipment due to their high hardness, wear resistance, corrosion resistance and scaling resistance. Not only can it effectively prevent scaling, improve the operating efficiency and stability of the equipment, but also significantly reduce maintenance costs and energy consumption. From industrial circulating water treatment to urban water plants, from seawater desalination to softened water treatment, alumina ceramic valves are becoming the core components of water treatment equipment upgrades, helping water resources utilization move towards a cleaner and more economical future.
