What is the best filter for circulating water?
Thread Content
We have a lot of sludge in our circulating water, and there are no conditions for sedimentation. What filtration methods do you recommend? If you know of any effective ones, please feel free to share them.
About 5–10% of the total amount of circulating water can be taken for filtration; fiber filters are generally sufficient for this purpose! You might as well give it a try!
For circulating water filtration, there are specialized bypass filtration devices, with approximately 5%-10% of the circulating water being filtered through these devices. It will get better after running for a longer time. Both of the circulating water systems I have here are equipped with bypass filtration units.
It might be due to poor control of microbial indicators.
A side filter can be added for filtration.
Our unit uses quartz sand side filtration, and the results are good.
Our unit uses valveless filters, and they work well.
Why not consider using a plate and frame filter press?
How much does it cost to invest in valveless filters and bypass filters? Are they practical? Is it easy to modify them?
I recommend using a \"sand filter\" for filtration. There are generally two options: pressure-type and gravity-type. Our company currently uses the gravity-type filter, which works very well and is capable of filtering out SS particles to levels below 5 ppm. You can search for \"Juzhan\" on Google to find information on their website
There is just a lot of sludge, so a plate and frame press will suffice; if the volume of water to be treated is large, several presses may be needed.
Automatic backwashing isn’t necessary if the filter will do; the simpler, the better. Filler made of quartz sand or anthracite will do
A few years ago, at Tsinghua University, I saw sewage treatment equipment designed specifically for dealing with sediment; it used membrane filtration technology and worked very well – it was quite impressive
A valveless filter is a good filtering device for circulating water. We’re using it too; it’s great.
It is a common practice to install a side filter in recirculating water systems for filtration; the investment required is low. Quartz sand is used as the filtering material, making operation and maintenance straightforward, and the operating costs are also not high. We use a side-filter tank with a concrete structure.
The most reasonable design is to use a side filtration system to reduce suspended solids in part of the circulating water, thereby maintaining an equilibrium of suspended solids in the system. The side filtration system can be implemented in various ways, such as sand filters, air flotation tanks, valveless filters, etc., but filter presses and the like are not used.
If a traditional multi-media filter is used, the output is low, operation is cumbersome, and it requires a large amount of space. Valveless filters are simple to operate and are now widely used. However, modern factories now also use cellulose filters, which have a high filtration rate; this reduces the number of required devices and lowers the costs associated with construction work. Disk filters have also become increasingly popular in recent years, as they offer high throughput, space savings, and automatic backwashing capabilities. The poster considered choosing one based on the circulating water volume of his own factory, its actual area, and financial conditions.

PCF fiber filters are a good choice: they can handle large volumes of water, take up little space, though they are a bit expensive
