Ceramic Valves for Wastewater Recycling & Corrosive Media Treatment
May 15, 2024
Ceramic valves have become an essential component in wastewater recycling systems due to their durability and resistance to corrosion. These valves are able to withstand the harsh chemicals and high temperatures often found in wastewater treatment plants, making them ideal for use in this critical process. One of the key benefits of ceramic valves is their ability to maintain a good seal even after prolonged exposure to corrosive materials. This ensures that no contaminants leak back into the environment, protecting both human health and the ecosystem. Furthermore, ceramic valves require minimal maintenance compared to traditional metal valves, reducing downtime and operational costs for wastewater treatment facilities. Their long lifespan also makes them a cost-effective choice in the long run.
Applications of ceramic valves in wastewater recycling
In the manufacturing process, some pipeline media themselves carry certain changing characteristics. Analysis of the reasons for the changes can be found to be mainly combined with changes in the production process, and during the changes, the pH of the medium will also change. For example, in the chlor-alkali industrial production, in the production process of caustic soda, if the resin tower in the electrolysis process is to be regenerated, it must go through the steps of backwashing, acid regeneration, water washing, and alkali regeneration. At this time, two forms of wastewater will appear, namely acidic and alkaline wastewater. In order to improve the utilization rate of wastewater, technicians in this study adopted a segmented recycling scheme to complete wastewater treatment. In this process, technicians discovered that the wastewater in the pipeline would form two types of wastewater, acid and alkali, which would alternate in stages. When dealing with pneumatic valves using this medium, people are more inclined to choose fully plastic-lined single-seat control valves based on the current status of industrial production. However, when this valve is applied, it is subject to many restrictions. Not only does it need to ensure that the temperature on site are appropriate, but the pressure must also be OK. Take F46 (FEP) as an example. It is a fluorine plastic. When chlor-alkali is processed, the temperature of the medium is required not to be higher than 150°C. Once the temperature is too high, the F46 lining of each component will deform and soften in a very short period of time, resulting in the valve not being closed well and increasing the amount of leaked produced chemical liquid and causing a waste of production resources.

In the field of industrial production, professionals generally regard ceramics as the mother of all inorganic materials. For a long time, traditional ceramics have always had the advantages of corrosion resistance, high-temperature resistance and good strength. As the scale of the industrial industry continues to expand and develop with the growth of market demand, it has promoted the performance improvement, scope of applications and expansion of use fields of new ceramics. In this industry context, after in-depth analysis by technical personnel, it was found that there are three main raw materials in new ceramics based on their composition, namely magnesium oxide, alumina and silicon dioxide. It is the existence of such substances that gives Ceramics extremely good corrosion resistance.
At present, in the chemical production industries such as silicon and salt, the application rate of ceramic valves is extremely high. Analyzing its composition, it is mainly a type of fully lined ceramic metal seated ceramic ball valve. The valve body is mainly made from ceramic. The main composition is stainless steel lined with ceramics. All parts of the ceramic surface that need to be connected to the metal are processed using a hot fitting process to improve the firmness and reliability of the connection between stainless steel and ceramics. Overall mechanical strength of ceramics also increases. When structural ceramics are made into ceramic steel, the positions and materials in contact with the medium are all structural ceramics.
At this stage, the use of valves made from ceramics in professional fields has significantly improved the corrosion resistance of the valves, which can meet the production needs of any other chemical media products except hydrofluoric acid. In addition, in terms of temperature, the maximum temperature that ceramic valves can withstand has reached 220°C. Compared with traditional plastic-lined valves, their high-temperature resistance is significantly better. It can be seen that in chlor-alkali industrial production, because the production medium is usually assisted by highly corrosive materials such as alkaline or acidic, it is important to fully apply ceramic ball valves in production at this time, which is important for improving production efficiency.
