What filter press is good for sludge wastewater treatment in paper mills?
With the rapid development of the paper industry, paper mills will produce a large amount of wastewater in the production process, which contains a large amount of suspended solids, organic matter and chemical substances. In order to protect the environment, paper mills need to effectively treat wastewater, in which the separation of sludge and wastewater is an important part of the treatment process. So, what kind of filter press is good for sludge wastewater treatment in paper mills?
The commonly used filter presses for sludge wastewater treatment in paper mills include plate and frame filter presses and chamber filter presses. Both of these filter presses are well-established dewatering equipment and have a wide range of applications in the field of sludge treatment. Below we will compare these two filter presses from the following aspects to help paper mills choose the right equipment.
1.Processing effects.
The plate-and-frame filter press uses high-pressure filtration and is capable of treating various types of sludge, including sludge with high concentration, high viscosity, and high oil content. At the same time, its filtration area is large, and different filtration areas can be selected according to actual needs to meet different treatment needs. The chamber filter press adopts gravity filtration, which has a relatively poor filtration effect, and is mainly used to treat sludge with low concentration, low viscosity and low oil content. Therefore, in terms of treatment effect, plate and frame filter press has more advantages.
2.Running costs.
The plate and frame filter press adopts a high-pressure filtration method, which requires high power consumption and high equipment maintenance costs. The chamber filter press adopts gravity filtration, which has relatively low operating costs and low equipment maintenance costs. Therefore, in terms of operating costs, chamber filter presses are more advantageous.
3.Equipment footprint.
Plate and frame filter presses require a large space to install the equipment, while the filtration speed is slower and takes a longer time to complete the filtration process. The chamber filter press has a smaller footprint and a faster filtration speed, which can complete the filtration process quickly. Therefore, in terms of equipment footprint, chamber filter presses are more advantageous.
4.Scope of application.
Plate and frame filter presses are suitable for a variety of different types of sludge treatment, including sludge with high concentration, high viscosity, high oil content, etc. The chamber filter press is mainly used to treat sludge with low concentration, low viscosity and low oil content. Therefore, in terms of the scope of application, the plate and frame filter press is more advantageous.
To sum up, paper mills need to consider comprehensively according to the actual situation when choosing a filter press for sludge wastewater treatment. If you need to deal with sludge with high concentration, high viscosity and high oil content, or if you need high filtration effect and processing speed, you can choose a plate and frame filter pressIf you need to handle sludge with low concentration, low viscosity, low oil content, or if you need low operating costs and equipment footprint, you can choose a chamber filter press. At the same time, it is also necessary to pay attention to the maintenance and maintenance of the equipment to ensure the normal operation and service life of the equipment.
