Which filter press is better to use

In fact, the filter press equipment is solid-liquid separation equipment, mainly including: plate and frame filter press, belt filter press, gap filter press, van filter press. The main function of these filter press equipment is to complete the solid-liquid separation of materials, especially for the high water content and large volume of sludge. 

Again, this sludge is relatively high in environmental pollution levels. When this sludge is present in many projects or factories, there is no way to properly dispose of it. In addition, transportation costs are indispensable for outward transportation, so it is necessary to stop solid and liquid separation of sludge, and leave the liquid, can be used repeatedly, solid can be extinguished and burned. But in the selection of filter press equipment, there are still some needs to pay attention to the center. Are you looking for sludge filtration equipment or sludge disposal equipment? If it is sludge filtration equipment, it is the filter press.

If it is sludge disposal equipment, such as mechanical mixing equipment, combustion furnace, sludge boring machine and so on. If you do not know how to dispose of the sludge and wastewater from your factory, do you want to filter or concentrate the sludge first, or dispose of the sludge cake after filtering?

This is a complete set of sludge filtration plan, but also requires a sludge filtration consumption line to complete. Of course, it's hard for people who don't know much about it. Where is the difference between plate and frame filter press and box filter press? 

1. Feeding position: The common feeding mode of the van filter press is the middle feed, and the local old equipment is the middle feed or the corner feed; The feed of plate and frame filter press is Angle feed. 

2. Filter plate structure: the panel filter plate is an integral filter plate. Plate and frame filter plate is composed of one plate and two plates. 

3. Filter media: the filter media of the van filter press is mainly filter cloth; The filter material of plate and frame filter press has a variety of options, such as filter cloth, filter paper and filter film. 

4. Automation level: no matter the size of the plate and frame filter press can not complete automatic operation; Chamber filter press to complete automatic operation. This situation is mainly due to the formation of different filter plate structure. In summary, the working principle of the van filter press and the plate and frame filter press, the structure of the filter press is fundamentally the same, the difference lies in the difference of the filter plate. What is the water produced by sludge press filtration? Although it may seem very clear, the COD, BOD5, SS in the supernatant (waste water) discharged by sludge press filtration, some items or some items such as ammonia nitrogen, fecal Escherichia coli group, colony number and other indicators are also very likely to exceed the standard, or belong to sewage. (Exceeding the standard refers to exceeding the standard of sewage discharge. In the calculation of sewage treatment plants, the current level A standard is mostly implemented: COD50mg/L and ammonia nitrogen 5mg/L. Whether the effluent can be discharged directly depends on whether the effluent quality can meet the discharge standards. At present, the supernatant (waste water) produced by sludge pressure filtration in sewage plants must conform to the discharge standards. Many central governments have requested sewage plants to stop the transformation and implement higher and more stringent discharge standards. Therefore, the supernatant (waste water) generated by sludge pressure filtration needs to be re-entered into the sewage treatment equipment to stop disposal.

The above is about the filter press which good content, if there is a friend interested in the filter press, can look at the past related content, I hope to help you.
