HDS HIGH DENSITY SCRUBBER DRY SCRUBBERS for the removal of: • High concentrations of corrosive contaminants • Odors generated in municipal wastewater, industrial plants, and sewage treatment STAINLESS STEEL • MILD STEEL • ALUMINUM

THE SOLUTION TO CORROSION & ODOR CONTROL THE HIGH DENSITY SCRUBBER (HDS) The High Density Scrubber (HDS) removes corrosive, malodorous and toxic contaminants and is designed for applications requiring high removal efficiency and extensive media life. The HDS system integrates three principal components: an industrial blower, a vessel containing chemical media and a discharge particulate filter section. The contaminated air is blown through an even-flow plenum section by the skid-mounted industrial blower. The air is then forced up through a deep bed of MULTI-MIX® media for removal of gaseous...

THE SOLUTION TO CORROSION & ODOR CONTROL FEATURES • Rugged industrial construction for maximum protection against corrosion and other severe environmental conditions. • Complete range of MULTI-MIX® chemical media to suit various applications. • Factory-assembled packages to facilitate installation and start-up. Partially assembled systems are also available where passage is restricted. • Counter flow design to reduce maintenance downtime using gravity loading and unloading. OPTIONS • Service/media loading platform, FRP or steel construction • 100% Fan redundancy (back-up capacity) • Preheat section...

CHEMICAL MEDIA FILTER HOUSING The chemical media filter housing shall be constructed of: (select one) 14-gauge 316 stainless steel, 10-gauge aluminum, or 14-gauge zinc coated steel). The housing shall be non insulated, single wall construction, reinforced to provide structural integrity. The housing shall be designed to provide a high degree of sealing integrity with all floor to wall and wall to wall interfaces specially sealed for weatherproofing and high static pressure leakage prevention. The chemical media filter bed support shall consist of 20 gauge stainless steel 316 perforated sheets....

INLET SECTION AND PRE-FILTERS Section shall be constructed of: (select one) 316 stainless steel, aluminum, or zinc coated steel, single wall-uninsulated. Access door shall include stainless steel hinges complete with positive pressure stainless steel latches.The entire perimeter of the access door shall contain a closed cell neoprene gasket. Pre-Filters Roughing pre-filters shall be 2" (51 mm) deep in direction of air flow having a minimum efficiency reported value of 30% (MERV 6) by ASHRAE Standard 52.2-1999 test method using atmospheric dust. Filters shall be UL Class 2 as per Standard 900....

b) Impellers shall be solid FRP composites of backward inclined design with a venturi inlet cone and a sprocket embedded and encapsulated into the backplate. The wheel is locked on to the shaft by using a taperlock bushing which is protected from the airstream by an FRP cap. A static and dynamic balance of the component is done to ensure smooth operation. Mild Steel Coatings All fans shall have a prime finish coat of red oxide primer. Unless otherwise specified this will then be followed by two coats of corrosion resistant aliphatic polyurethane finish on all mild steel surfaces. Fan and Motor...
