Cuando se agrega US Ecology, now part of Republic Services, expanded its Beatty, Nevada, hazardous waste stabilization operation, the company needed a dust collection system that would be dependable, easy to operate, and appropriate for a demanding process in a remote desert environment. Baghouse.com had already supported the facility for years with maintenance, filter changeouts, bags, cages, and general dust collector support, so when the expansion project began, the team reached out to us to help define the next phase.
The Beatty site handles hazardous materials from industrial sources. Some materials are treated in other ways, but for this part of the operation, the process involves unloading hazardous material onto large concrete mixing beds and blending it with stabilizing reagents such as lime, lime kiln dust (LKD), bentonite, and similar materials. Once stabilized, the material can be managed safely as part of the site’s disposal process.
According to Dominick Dal Santo of Baghouse.com, the project started with a design role. As he explained, “They actually hired us first to design the specifications for the system and for the bid package that eventually they would send to multiple vendors.” That early involvement gave Baghouse.com the chance to shape the system correctly from the start.
The goal was straightforward: support a new building with three enclosed mixing bays, each needing reliable dust capture, simple airflow paths, and collector equipment robust enough for high dust loading from reagent mixing.

Baghouse.com’s role centered on engineering and supplying a complete dust collection package for the new stabilization building, along with a later-added reagent storage silo system.
For the main dust collection portion of the project, the package included:
⦿ Three pulse-jet baghouse dust collectors- ⦿ Three New York Blower fan systems
- ⦿ Three complete ductwork systems
- ⦿ Three 50-foot exhaust stacks
- ⦿ Three 14-inch rotary airlocks
Later in the project, the scope expanded to include reagent storage and unloading equipment for the materials being blended into the hazardous waste stream. That package included:
- ⦿ Two reagent storage silos
- ⦿ Two bin vent dust collectors
- ⦿ Two auger screw conveyors
- ⦿ Two slide gates
- ⦿ Truck unloading piping
The project also included engineering support for commissioning and training.
Dominick described the original design goal in very practical terms: “They had worked with somebody else at a different plant, and they had a very complicated system for the dust collection. And they asked us to simplify it and recommend all the specifications for the dust collection system.” That became one of the defining features of the project… Baghouse.com designed a straightforward system that fit the building and the process.
Solución
The final design used three identical pulse-jet baghouses, one dedicated to each mixing bay. Each system was designed for 25,000 ACFM and built around a Baghouse.com 144TB-BHT-270 collector. Each collector included:
- ⦿ 270 filter bags
- ⦿ 5,258 square feet of filter media
- ⦿ 16 oz singed polyester bags with PTFE membrane
- ⦿ 6-inch diameter x 144-inch long bags
- ⦿ 270 galvanized 12-wire cages
- ⦿ Air-to-cloth ratio of 4.75:1 at 25,000 ACFM
- ⦿ Top-load filter access
- ⦿ Heavy-duty all-welded construction
- ⦿ NEMA 4 control panel
- ⦿ Dwyer DCT2010 clean-on-demand capable controller with 4–20 mA output
- ⦿ 18 premium long-life 1.5-inch pulse valves
- ⦿ 72 inches of hopper discharge clearance
- ⦿ OSHA access ladder, handrail, and service platform
The fans were New York Blower backward inclined Class 4 SWSI fans, each paired with a 100 HP motor, sized for the 25,000 CFM duty at the required static pressure.
On the reagent side, Baghouse.com supplied two legged, smooth-wall storage silos, each sized at roughly 169 tons nominal capacity, with:
- ⦿ Bin vent collectors
- ⦿ Screw conveyors
- ⦿ Pneumatic slide gates
- ⦿ Truck unloading piping
- ⦿ Ladder, platform, guardrail, and level probes
The bin vents themselves were compact pulse-jet units designed for 600 ACFM max per system, using pleated filters and differential pressure-based control.
Together, these systems gave the facility both source capture over the mixing operations and dedicated storage/venting support for the dry reagent side of the process.
Desafíos durante la instalación
Although the final system layout was simple, the project still had its share of engineering challenges.
One of the more important issues involved seismic and structural design for the area. The Beatty site required careful attention to foundation and stack requirements, especially for the tall exhaust stacks and elevated collectors. During the project, Baghouse.com had to revise the exhaust stack design to make it more robust and suitable for local conditions.
Dominick noted that this was one of the bigger hurdles: “After the project was in motion, we had to change the specification for how to design the exhaust stack… this place has tons of earthquakes, right? So they’re really picky about how you design the foundations.”
The team also had to make changes to the collector support height later in the project. According to Dominick, “At the last minute, they asked us to raise the baghouses up. So we had to make them taller and redo the engineering so that, again, they were rated for the earthquake ratings in the area.”
Another challenge was project timing. The reagent silo package was added after the main dust collection project was already underway, which meant integrating additional equipment without disrupting the broader schedule. That required coordination with the general contractor, Bodell Construction, and careful management of fabrication and project sequencing.
Even with those changes, the project stayed focused on a clean, workable solution rather than letting complexity creep into the design.
Resultados y conclusión
The Beatty Stab 2 project is a good example of how Baghouse.com can contribute well before equipment is built or installed. In this case, the value started with helping define the system itself. Baghouse.com served as the technical dust collection partner during the design phase, created the specification package, supplied the main equipment, and supported the project as it moved from concept to execution.
The result was a three-bay dust collection system built around straightforward source capture, appropriately sized pulse-jet baghouses, properly matched fans, and a supporting silo system for the dry reagents used in stabilization. The design also gave the plant room to operate and maintain the equipment without dealing with unnecessary duct complexity.
Just as importantly, the project built on an existing relationship. Baghouse.com had already supported the site for years before the expansion. That familiarity with the plant and its needs helped make Baghouse.com a more useful engineering partner when it came time to scale up.
For facilities planning a new hazardous materials process, expanding a reagent handling system, or simply trying to avoid overcomplicating a new dust collection installation, this project shows the value of involving dust collection specialists early.
