BHS Batch/Continuous Filtration and Clarification for Low Solids Concentrations Clarification and Recovery Applications with the BHS Candle and Pressure Plate Filters

BHS Batch/Continuous Filtration and Clarification for Low Solids Concentrations • Applications include water & amine scrubbers, chlor-alkali, chemical, biodiesel, gasification / grey water, activated carbon, catalysts, heavy metals, PTA fines and pharmaceutical • Replaces filter presses, manual plate filters, bag, cartridge, metal filters and centrifuges • Filtration to 0.5 um, cake washing and drying • Precoat of the filter media is possible, if required • Complete containment and Automatic discharge

BHS Batch/Continuous Filtration and Clarification for Low Solids Concentrations Candle Filter: Vertical Cake Structure Cake discharge by gas expansion of the filter media

Pressure Plate Filter: Horizontal Cake Structure Cake discharge by plate vibration & gas-assist No spinning plates-eliminates solids sticking No rotating or mechanical seals-eliminates leakage
