BoCross^® Filter

The Dynamic Crossflow Filtration System employs advanced crossflow (tangential flow) filtration technologies to continuously separate suspended solids from liquid streams without forming a filter cake on the filtration surface. By generating shear forces across the filter medium, this system maintains efficient filtration rates, minimizes membrane or screen clogging, and enables high solid content concentration. It supports options for dynamic sieve filtration or microfiltration using screen or membrane elements to meet diverse process requirements.

Traditional dead-end filtration approaches often suffer from rapid filter cake buildup and pore blockage, leading to higher differential pressures and decreased performance over time. In contrast, dynamic crossflow filtration circulates slurry in a flow direction different from the filtrate, reducing fouling and maintaining long-term operational stability. This system is ideal for industrial solid-liquid separation, high-viscosity slurry filtration, and highly concentrated suspension processing across various manufacturing applications.

 Typical Application Scenarios

This dynamic crossflow filtration system is designed for demanding industrial applications where efficient separation and high-quality filtration clarity are essential:

• Inorganic Material Dewatering and Concentration — Calcium carbonate (CaCO₃), silicon dioxide (SiO₂), barium titanate and similar high solids suspensions.
• High-Viscosity and Non-Newtonian Fluid Filtration — Effective operation with viscous slurry mixtures.
• Submicron and Nano-Scale Particle Filtration — Clarification and concentration of fine suspensions.
• Fine Chemical, Pharmaceutical, and Electronic Material Processes — Enhancing product yield, solids recovery, and downstream purity.

 Including typical usage scenarios like catalyst recovery within continuous chemical processes enhances search relevance for engineers and procurement professionals seeking industrial filtration solutions.
