In today’s industrial production and environmental protection field, filter press plays an indispensable role as an important solid-liquid separation equipment. However, many different types of filter presses exist in the market, such as plate and frame filter presses, belt filter presses and chamber filter presses. Understanding their performance, price and applicable scenarios is crucial for customers to choose the right product.
- Plate and frame filter press
1.Performance Characteristics
– Large filtration area: Due to its structural design, it can accommodate more filter plates and frames, thus providing a larger filtration area, which is suitable for working conditions with large processing capacity.
– High filtration pressure: it can generate high filtration pressure, which makes the solid-liquid separation more thorough and the solid content of the filter cake higher.
– Strong adaptability to materials: it can deal with materials of various natures, including materials with high viscosity and high solid content.
- Price factor
– Relatively high initial investment: due to its complex structure and high manufacturing process requirements, the purchase price of plate and frame filter press is usually high.
– Moderate maintenance cost: Although it is necessary to regularly replace the filter cloth and other wear parts, the maintenance cost is within the acceptable range.
- Applicable Scenarios
– Chemical industry: used to handle filtration of chemical raw materials, intermediates and products, such as pigments, dyestuffs and pharmaceuticals.
– Mining industry: dewatering of ore slurry and recovery of useful minerals.
– Food industry: used for solid-liquid separation during food processing, such as filtration of starch, fruit juice, etc.
Second, belt filter press
1.Performance Characteristics
– Continuous operation: continuous feeding, filtering and discharging can be realized, with large processing capacity, suitable for large-scale production.
– Simple operation: the degree of automation is high, and the operator only needs to carry out simple monitoring and adjustment. Small footprint: the structure is compact and occupies relatively little space.
– Small footprint: compact structure, occupies relatively small space.
- Price factor
– Medium initial investment: the price is relatively more affordable than the plate and frame filter press, suitable for customers with limited budget.
– Low operation cost: low energy consumption and relatively low replacement frequency of wearing parts.
- Applicable Scenarios
– Wastewater treatment plant: sludge dewatering treatment of municipal sewage and industrial wastewater to reduce the volume of sludge.
– Paper-making industry: used for pulp dewatering and recycling, improve the quality of paper.
– Food processing industry: such as the processing of vegetables, fruits in the process of wastewater treatment.
Third, chamber filter press
1.Performance Characteristics
– Compact structure: small external dimensions, easy to install, suitable for occasions with limited space.
– High filtration efficiency: adopting high-quality filter plate and sealing technology, it has good filtration effect and low water content of filter cake.
– Strong corrosion resistance: corrosion-resistant materials can be selected for manufacturing, suitable for corrosive materials filtration.
- Price factor
– Moderate initial investment: the price is between plate and frame filter press and belt filter press.
– Low maintenance cost: the filter plate has a long service life and the maintenance workload is relatively small.
- Applicable Scenarios
– Small factories: for enterprises with small production scale, chamber filter press is an economical and practical choice.
– Electronic industry: used for wastewater treatment in the production of electronic components.
– Pharmaceutical industry: filtration and separation of small batches of drugs.
- Selection guide
- Selection according to processing capacity
– The working condition with large processing capacity can give priority to plate and frame filter press or belt filter press; for occasions with smaller processing capacity, chamber filter press may be more suitable.
- Selection according to material properties
– For materials with high viscosity and high solid content, plate and frame filter press has advantages; for corrosive materials, corrosion-resistant chamber filter press can be chosen.
- Selection according to budget
– Customers with sufficient budget and high filtration effect requirements can choose plate and frame filter press; with limited budget but continuous operation, belt filter press is a good choice; chamber filter press provides a balance between price and performance.
In short, different types of filter presses have their own characteristics in terms of performance, price and applicable scenarios. Customers should consider various factors according to their own needs and actual situation when choosing, and select the most suitable filter press product for them, in order to achieve efficient solid-liquid separation and maximize production benefits.
