How to choose a fan that suits you? Come and take a look (especially regarding wastewater treatment)

With the increasing emphasis on environmental protection, regulations in this area are becoming stricter year by year. Wastewater treatment has become increasingly important for many enterprises. Today, I will give you a brief overview of aeration blowers used in wastewater treatment, and how to choose one that is suitable for your needs. Firstly, the blowers used for aeration in wastewater treatment systems are usually operated around the clock, without interruption; therefore, the stability of the machines, their energy efficiency, the likelihood of failures, and the ease of maintenance are all very important. In some companies, production halts due to the shutdown of blowers are a common occurrence. Especially with many domestic machines, after being used for a long time, issues such as overheating, oil leakage, and shutdowns are quite common, and there are various reasons for this; we won’t go into detail here. Secondly, since sewage aeration blowers operate around the clock, electricity consumption is a concern for many companies; therefore, choosing energy-efficient machines is also something that many businesses pay attention to these days. Unlike tap water, where the system doesn’t need to be in use for more than a few hours a day, energy savings through aeration of wastewater is of utmost importance. Many enterprises have to shut down due to inability to afford electricity costs; therefore, energy conservation is an inevitable trend for businesses. Ultimately, the best choice is one that meets your specific operating conditions – tailor it to your needs. Many companies say that since others find it so good, we need to use it as well. That’s right; it’s something meant for others, and it may not be suitable for you. Therefore, it’s crucial to have a professional help you with testing and making the right choice. Let’s take a simple example: Centrifugal fans (air-suspended centrifugal blowers/magnetic-suspended centrifugal blowers) are very popular these days; they can save around 30% in energy consumption. They are indeed high-tech products and excellent in many ways, but are they suitable for you? Let’s briefly discuss the operating conditions for centrifuges: 1. New-type centrifuges have many electrical components, and they have high requirements regarding temperature, humidity, dust, etc. 2. High stability is required for the operating conditions; otherwise, it can lead to problems such as shutdowns (in the wastewater industry, the optimal operating head range for centrifuges is 6–8 meters). So, to sum it up: for fans, those that are stable, energy-efficient, and capable of meeting the specific requirements of your operating conditions – that is, fans tailored to your needs – are the most suitable ones for you. In the next issue, I’ll have time to talk to you about the history of rotary vane blowers, as well as their advantages and disadvantages. I hope this will be helpful to everyone.
