How to remove solid suspended particles from liquids!
Thread Content
Background: This product is in tablet form and is highly soluble in water. Due to packaging or other reasons, some waste will be generated. The device contains storage tanks for recycling waste materials. The process of recycling waste materials involves pouring hot water into the hopper containing the waste, which dissolves it; thereafter, the valve is opened to transfer the dissolved waste into the waste storage tank. An submersible pump installed in the tank then pumps the waste back into the system for reprocessing. Status: During the recycling of waste materials, many impurities and trash end up in the waste storage tank along with the dissolved waste (the hopper is equipped with a filter screen with 80-mesh density). During the material mixing process, the filter screen can also be damaged by impacts, allowing impurities to enter the storage tank. ), the self-cooling bearing system of submersible pumps often suffers wear due to impurity particles, causing severe vibration in the pump, which ultimately leads to its shutdown for maintenance. The maintenance frequency is high. Question for help: How can suspended particles in a liquid phase, such as dust, fine sand, and metal particles, be removed? What method is the most cost-effective (while minimizing expenses)? At first, I thought of using sedimentation, but it takes too much time, and I’m worried that the particles won’t settle properly if the process is repeated continuously. I’m reaching out to everyone for help! Thank you!

I need help with a question; please come back quickly to answer it, not to share anything. . .
Since filtering doesn’t work to solve the problem, it’s better to choose another type of pump. How about a self-priming pump? Give it a try
Solid particles can be filtered using filter presses, and flocculation can be enhanced, etc
Sand and metal particles can all remain suspended – what is the density of your medium?

Can heating be used to reduce viscosity for precipitation and separation? Can a volute-type separator be used for sedimentation separation? Tangential feeding, with a deposition hopper located at the bottom center, and discharge from the top center of the volute? ? Can a slurry pump be used to remove the residual liquid? ? ?
What is a volute? Isn’t it called a swirl chamber?
For this, filtration, sedimentation, pressure filtration, and centrifugation are the only options. It depends on your own requirements!
The cost of replacing the pump is too high～～ The existing pump is included with the tank, and its opening has a diameter of DN700. . .
The density is not very high, around 0.9, but the viscosity is somewhat higher, at 0.08 Pa·s
