Attention to those in the petroleum, chemical, and pharmaceutical industries: Choosing the wrong filter will cause a sharp increase in consumable and labor costs! How to select between candle-type and plate-type filters? We clarify their core differences for you.
1. Structure: The difference lies in whether filter cakes accumulate!
Candle type Filter: Bundled suspension design with a 6+1 plum blossom structure. No obstruction at the bottom ensures uniform filter cake distribution without accumulation.
Plate type Filter: Equipped with thick horizontal collecting pipes and vertical installation. Filter cakes tend to accumulate between plates, and cake discharge may get stuck.
2. Efficiency: 5 minutes vs. 1 hour - speed speaks for itself!
Candle type Filter: Seamless filter cartridges with adjustable precision. Filter cakes form in 5-10 minutes, making it highly convenient for mass production.
Plate type Filter: Uses wire mesh plates (100-150 mesh). It takes 1 hour to form filter cakes, and there is a risk of filtration leakage.
3. Filter Aid: Cost-saving vs. cost-increasing!
Candle type Filter: Zero filter aid addition for activated carbon filtration. Only a small amount is used for extremely difficult materials, saving money and reducing troubles.
Plate type Filter: Often requires diatomite or cellulose. This leads to a dual increase in solid waste and material costs.
4. Drying: 20% vs. 60% moisture content!
Candle type Filter: Stable plum blossom structure prevents filter cake falling off. Moisture content ranges from 20% to 40% (can be <20% with activated carbon).
Plate type Filter: Filter cakes are prone to falling off and air leakage. Moisture content is between 40% and 60%, and extended drying time is ineffective.
5. Operation: One-click vs. multi-person - labor cost is halved!
Candle type Filter: Fully automated. One-click operation for filtration, drying, and cleaning, with extremely simple maintenance.
Plate type Filter: Manual or semi-automatic operation. Requires coordination of multiple personnel, and residual liquid cleaning also relies on manual work.
6. Application: High-demand vs. simple tasks!
Candle type: Suitable for high-demand scenarios such as petroleum, pharmaceuticals, and chemicals, featuring high efficiency, airtightness, and high precision.
Plate type: Only applicable to liquids with low concentration (<50%) and low residue content, suitable for basic filtration needs.
Summary
Choose the candle type for high efficiency and cost savings; choose the plate type for basic filtration with limited budget.Unsure about which type fits your process? Email us at sales@geziexport.com, and we will help you customize a solid-liquid separation solution to avoid selection mistakes!
