Comparison of filter press selection, which one has more advantages in treating sludge?

 Now, no matter which industry it is, and no matter what kind of sludge treatment equipment is needed, filter press is indispensable after all, because whether it is to compress the sludge first or to transport the sludge, it still needs to be processed. The effect of dewatering sludge will be better than that of dewatering sludge, because only filter press equipment can effectively utilize the sludge and meet environmental protection standards after filtration. For example, some sludge is filtered and the filtrate becomes clear water, which can be directly It is recycled again. As for the filtered mud cake, some are landfilled and incinerated, and some are recycled and reused, depending on the needs of various industries, and only filter press equipment can achieve these. Therefore, users are dazzled when it comes to filter press selection, because not every filter press can achieve low filter cake moisture content and high filtration speed. Today we will analyze the advantages and disadvantages of these filter press models.

Plate and frame filter press

Advantages: Generally speaking, the plate and frame filter press is a large-scale equipment. Because it can form filter chambers of different volumes through filter plates, so as long as the size of the filter plate is large enough, the volume of the filter chamber that can be formed is also large enough. Those tailings In terms of processing, I prefer to buy a plate and frame filter press. Generally speaking, it consumes less energy and does not consume electricity. In terms of dehydration effect, it is better than a belt filter press.
Disadvantages: Because it is an intermittent filtration equipment, although it can process a relatively large amount of sludge each time, it takes a long time to process the sludge once and needs to be processed cyclically, so it is still lacking in filtration efficiency. , and there are many places that require manual operation. Of course, if it is a fully automatic plate and frame filter press, it will be another matter.

Belt filter press

Advantages: It can complete continuous work without stopping. In terms of filtration efficiency, it is higher than the plate and frame filter press, and the sludge treatment capacity that can be completed is relatively large.
Disadvantages: From the perspective of the sludge dehydration effect, it is not very thorough. The moisture content of the mud cake is slightly high and the shape is not good. Moreover, the filter belt of the belt filter press requires a large amount of water to be rinsed after each use, which is wasteful. It is easy to break when using water.

Membrane filter press

Advantages: The sludge dehydration effect is relatively good, better than plate and frame filter press and belt filter press. Especially in municipal sludge treatment, it can achieve a mud cake solid content rate of 85%, which is still very good.
Disadvantages: When filtering with a membrane filter press, a relatively strong high-pressure water system is required, which consumes more water, and the price is relatively high relative to the price.

Sludge press dryer

Advantages: It can realize fully automatic operation, the filtering effect is very good, and the speed is also fast.
Disadvantages: expensive

When selecting the above filter press equipment, some customers will ask: nearly 10 tons of sludge are processed every day, and the solid content of the mud cake is about 85%. How much does such a filter press cost? In fact, regarding the price of filter press, we have said before that it not only depends on the filtration effect and filter press model, but also depends on many factors such as filtration area and filtration speed.

As for what should be done when selecting a filter press, I believe that through the above comparison, users should have a basic understanding when choosing a filter press model. As for the price of the filter press, it still depends on which filter press is chosen. It is determined by the machine produced by the filter manufacturer and the specific filter press parameters.
