3.1.7: Does BHS manufacture completely skid-mounted systems including piping, valves instruments and PLC controls?
Yes, this is a standard scope of supply based upon an approved P & ID.
3.1.6: What are the Process Benefits?
• Full containment of solids, liquids and vapors • Automatic operation • Replaces filter presses, bag filters & manual plate filters • Eliminate pre-coat and/or body feed • Clean-in-place • Recovery of catalysts and activated carbon • Clarification of pharmaceutical and chemical solutions
3.1.5: What are the Automatic Process Cycles?
• Filling: The slurry feed enters the bottom of the filter vessel. • Filtration: The slurry is pumped under pressure into the vessel. Cake will deposit on the outside of the candle; the separated filtrate will flow through the filtrate pipe and the registers. This process continues to a maximum pressure drop, the maximum cake […]
3.1.4: How are the Filter Vessel & Candle Registers constructed?
Vessel is constructed of various types of stainless steel, Hastelloy or can be lined with EPDM or other similar coating. Within the vessel are candle registers. Each candle is connected to a register with a positive seal to prevent bypass. Each register may contain from 1 – 10 candles depending upon the filter size. The […]
3.1.3: What type of filter media can be used and what is the finest removal efficiency?
The filter media is a synthetic media such as Teflon, polyester, polypropylene, PEEK, duplex media, Nylon and others. The clean removal efficiency to 1-3 microns but as the cake builds up on the candles; removal efficiency can be below 0.5 microns.
3.1.2: Can you describe the candles?
The filter candles consist of three components: single-piece filtrate pipe, perforated core with outer support rods and filter media. The filtrate pipe is the full length of the candle and ensures high liquid flow as well as maximum distribution of the gas during cake discharge. The perforated core can be a synthetic material, stainless steel […]
3.1.1: What operations are conducted on the BHS Candle Filter?
The BHS candle filter provides for pressure filtration, cake washing, drying, reslurry and automatic discharge as well as heel filtration in an enclosed and pressure vessel.
