Pressure Filtration for Chemical Processing and Scrubber Blowdown Treatment
Chemical processing plants, industrial air scrubber systems, and specialty chemical manufacturers generate process liquid streams with contamination profiles that standard filtration equipment cannot handle — aggressive pH, elevated temperature, high solids loading, and chemistries that corrode carbon steel and even standard stainless steel systems. K Factor's automatic backwash pressure filtration systems are configured for these environments with materials, seals, and operating parameters matched to the specific chemistry.
Industrial scrubber blowdown filtration
Wet industrial scrubbers — used to remove acidic gases, particulate, VOCs, and heavy metals from industrial exhaust stacks in chemical plants, metal finishing operations, foundries, and power generation facilities — generate a continuous liquid waste stream called scrubber blowdown. This water, saturated with the contaminants captured from the exhaust gas, contains suspended solids, dissolved metals, and chemical compounds that must be treated before discharge or reuse.
K Factor automatic backwash pressure filters are installed as the solids-removal first stage in scrubber blowdown treatment circuits. The filter removes suspended particulate — typically metal oxides, calcium sulfate scale, captured fly ash, and process residues — protecting the downstream treatment equipment (neutralisation tanks, secondary filters, evaporators) from solids loading that would otherwise shorten service life and increase maintenance frequency.
- Typical contaminants: Metal oxides, calcium sulfate, captured particulate from exhaust gas, chemical residues
- Material selection: Polypropylene-lined carbon steel or 316L SS depending on pH and temperature
- Micron ratings: 25–100 micron for coarse solids capture ahead of secondary treatment
- Integration: Inline on the blowdown stream between the scrubber sump and the treatment system
Chemical process stream filtration
K Factor backwash pressure filters in chemical processing applications are selected and configured for:
- Acidic streams: 316L SS, Hastelloy, or Duplex construction; PTFE or FKM seals; pH as low as 1
- Caustic streams: 316L SS with EPDM seals for sodium hydroxide and similar alkaline process streams
- High-temperature service: K-Optifil rated to 120°C standard; special configurations to 200°C for steam-condensate and polymer processing
- High-solids loading: Configured with larger reject chambers and higher-frequency backwash trigger points for streams with continuous high suspended solids
- Continuous operation: Chemical plants run 24/7; the filter must match — automatic backwash with no scheduled downtime for cleaning
Reactor feed and catalyst protection
In catalytic process reactors — common in petrochemical, pharmaceutical, and specialty chemical manufacturing — catalyst performance depends on clean feed streams. Suspended solids in the reactor feed coat and deactivate catalyst, reducing yield, increasing energy consumption, and requiring costly catalyst replacement or regeneration cycles.
K Factor backwash pressure filters on reactor feed streams protect catalyst beds by providing continuous, automatic filtration that maintains solids below the specification required to prevent catalyst fouling — typically 5–25 micron depending on catalyst type and reactor design.
