Advances in circulating water technology
Thread Content
In recent years, what advancements have been made in domestic circulating water technology? Please introduce it so that other sailors can share it.
Advances in circulating water technology in recent years: I. From the perspective of water conservation: 1. The concentration ratio of circulating water has generally increased； 2. Modifications and improvements to the design of strainers and air ducts, resulting in a **reduction in water loss rate** ； With the development of water treatment technologies, particularly the application of membrane technology, recycled wastewater from circulating water systems has been successfully recovered, while reclaimed water is used as make-up water. II. From the perspective of environmental protection: 1. Low-phosphorus and phosphorus-free formulations are being increasingly used ； 2. The corrosion rate and structural degradation of the heat exchange equipment have decreased ； 3. The use of alkaline self-raising pH-formulated products is increasing, which reduces corrosion and acid burns. 3. Cooling efficiency: Many new types of fillers have been introduced, improving the heat exchange efficiency per unit area ； There are also interchangeable blades, carbon shafts for fans, etc., which reduce and lower the maintenance rate.
Reply: 2# znb is right; it’s worth taking as a reference
Let’s discuss the current status of energy-saving measures. The circulating water runs 24/7, which results in millions of kilowatt-hours of electricity consumption
The last edit to this post was made by simuy on 2010-8-9 at 16:07. I think there are mainly two points: 1. Using advanced equipment such as kinetic energy recovery fans and efficient water removal systems to reduce power consumption and water splashing； Some manufacturers claim that the wind-induced loss rate of their products is below 0.00001 (one in one hundred thousand), which can be considered negligible. 2. Install a drainage reuse system to desalt the recycled water before reusing it. The reuse rate ranges between 0.65 and 0.75. Regarding the concentration factor, when the quality of the raw water remains unchanged, the level of operational expertise has an impact, which mainly includes the addition of chemicals, monitoring, and control.
Well said, it’s been enlightening:victory:
In addition to the positive aspects mentioned on the second floor, we must also take into account the fact that there are more middlemen, more people who lower prices arbitrarily, and as a result, manufacturers’ profits decrease.
