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 registers convey the liquid filtrate as well as the pressure gas for blowback. Each register is controlled with automated valves to ensure optimum flow in both directions.
