The Auto-Shok and Auto-Pulse Filters are classical tubular filters, also known as Candle Filters
AUTO-PULSE™ BUMP & RUN TUBULAR BACKPULSE FILTER
Auto-Pulse is a tubular backpulse filter designed to achieve submicron filtration without the use of precoats or filter aids in a vertical vessel with conical lower head for solids accumulation. This feature has the benefit of recovering small amounts of product from waste streams which can be returned to the process without contamination.
To deliver this unique capability, Auto-Pulse combines proven tube filter design and modern membrane technology installed in a highly permeable tube sheet that that has all the superior chemical and thermal characteristics of a candle filter operation.
Because there are no precoats, polymers or other chemicals to be stored, mixed and dosed, AutoPulse is less expensive and easier to operate than other designs.
Since the filtration performance does not depend upon cake formation for fine solids removal, flows can be stopped and restarted without affecting downtime or effluent purity.
Micron rated elements and cloths that deliver unparalleled filtration quality and instantaneous clarity within a wide range of solids concentrations, from solutions as dilute as 0.002% to slurries with over 10% solids content.
