Filtering Machine Rotary Drum Vacuum Filter

When to use a RDVF: 1. For general filtration where high rates, low cake moisture and clear filtrate are required. 2. For clarification, where filtrates free from suspended solids are desired, with low filter aid usage. 3. For cake washing, to yield high-purity filter cake using minimum wash liquor. 4. For extraction with high product recovery using minimum wash liquor. 5. For wastewater clarification to reduce or eliminate costly surcharges or the impact on downstream process. 6. For sludge dewatering, to reduce sludge volume by 95% or more, lowering handling and disposal costs.   Factors that affect RDVF rates: 1. Particle size, shape and concentration. 2. Vacuum levels and the cycle time in the cake formation, washing and drying zones. 3. The temperature and viscosity of the suspension.…
