BHS - Candle Filter
The BHS Candle Filter is designed for thin-cake, batch filtration and supports additional processes such as cake washing, drying, reslurry, and automatic cake discharge. The cake can be discharged as dry, wet, or concentrated slurry. Available in filter areas ranging from 0.17 m² to over 200 m² per vessel, the Candle Filter is ideal for clarification and recovery applications, handling liquids with low solids content ranging from 5% to ppm levels. BHS filter candles are engineered for high liquid flow and low-pressure drop. Cake discharge is achieved by distributing gas to gently expand the filter sock. The materials of construction include stainless steel, alloys, and plastics, with vessels optionally lined with EPDM, Halor, PTFE, or other materials. Additionally, filter aids can be used as a precoat and/or body feed, which is particularly beneficial for handling sticky products or challenging filtration tasks.
Efficient capture of fine solids
The filter media, including woven polypropylene, PTFE, Nylon, and Polyester, delivers high removal efficiency, down to 0.5 microns. As the cake builds up, the removal efficiency improves even further, reaching below 0.5 microns.
Automated Self-Cleaning
With simple controls and valve sequencing, the filter can be fully automated and operate completely hands-free in a fully contained system.
Low-Maintenance
The BHS candle filter has no moving parts, which enhances operational reliability and reduces maintenance needs. The unique surface design of each candle ensures that the cake fully separates before being discharged downward.
