1 Sponge-Jet and the Sponge Blasting System for Lead Abatement Ted Valoria, Vice President North America

2 Sponge Blasting System Introduction The Sponge-Jet Feed Unit / The Sponge-Jet Recycler Sponge-Jet Sponge Media

3 Sponge Blasting System The Sponge-Jet Feed Unit Delivers Sponge Media particles to the surface Monitors specific flow characteristics Optimizes production and rebound Controls mixture of Sponge Media particles and air

4 Sponge-Jet Sponge Blasting System The Sponge-Jet Media Recycler Prepares and cleans Sponge Media particles for reuse Separates media into three categories: Oversized debris Reusable Sponge Media Fines: spent media contaminants

5 New Abrasive Blasting Technologies Sponge Media Advantages: Clean, dry blasting process Low dust generation best visibility Low Rebound Wide range of profiles Non-abrasive / highly abrasive Reusable with simple classification Low volume requirements Non-Sparking Cleaner substrate - lower chloride levels

6 Sponge Media Particles Sponge Media particles are propelled to the surface using an air-driven system Upon impact the Sponge Media particles Absorb collision energy Flatten and suppress the release of loosened surface contaminants Expose its cleaning agent and removes contaminants Sponge Media particles Constrict to their former shape Entrap most of what would normally have become airborne

7 Why Create 5,500 Times the Dust? Blasting Cleaning with Sponge Media can reduce dust levels as much as 99.9% - compared to traditional abrasive cleaning methods.

8 Airborne Contaminant Comparison

9 Comparing Technologies Sandblasting Advantages Cost of media Available in bulk quantities Disadvantages Excessive dust Difficult to clean up Ability to control surface damage Contamination of rotating equipment Sponge Media Blasting Advantages Sponge traps contaminants, suppressing dust Blast near sensitive equipment Available in many levels of aggressiveness Media is recyclable; reducing media requirements & waste Disadvantages Cost of media requires low dust Special media classifier required for recycling Limited availability of equipment

10 Media Required - Lbs. Sponge Media Sponge Media is reusable, therefore... Media Consumption Comparison Job Size - Sq. Feet Pliant Media Conventional Media Pliant Media w/5 reuses

11 Removal of Lead Paint from Fire Hydrants Operator Safety - The suppression of airborne lead particles was critical in the small containment system Cutability - The process had to aggressively cut multilayered, 40 to 80-mil, lead coatings and provide a surface profile System Mobility - The system had to be mobile enough to fit down city and residential streets Quick Set-up and Clean-up - Efficient site preparation and cleanup was necessary to blast and repaint ten hydrants per day

12 Lead Paint Removal from Concrete at Cal Poly Lead-based paint was peeling in the pool house, posing potential health risks to it users. Dry and Easily Containable - Other wet, leaching blast technologies were impractical, or too costly to confine Low Airborne Dust - Lead dust suppression was critical to limiting exposure to system operators as well as surrounding students and faculty Safe for Workers and Employees - The process had to be safe to use with California s stringent EPA air quality regulations Process Sensitivity - The process had to be aggressive enough to offer efficient production rates, without damaging the concrete substrate

13 Removal of lead paint and heavy rust in an operating petroleum refinery Surface preparation and repainting was required on 3,450 ft 2 of structural steel in a Corpus Christi, Texas oil refinery The contractor s challenge was to allow nearby production units to continuously operate, and to maintain a dry, low dust environment Contractor was able to prepare the surface to the SP6 specification in one dry, low dust process - allowing oil production to continue. These same qualities allowed painting to quickly ensue. Using the Sponge Blasting System the job came in under the quote we provided to the refinery s general foreman. Paint & Lead Supervisor

14 Lead paint removal from shop ceilings and walls in an old textile mill 50,000 ft 2 of lead painted ceilings and walls in a converted Manchester, NH textile mill were being sandblasted in preparation for a new coating system Dust from conventional sandblasting began migrating to the mill s lower levels, which were occupied by operating businesses Marcor Remediation used the Sponge-Jet Sponge Blasting System to remove the remaining 35,000 ft 2 of lead paint - yielding, on average, 480 ft 2 per day Due to the clean, low-dust Sponge Blasting process, the Marcor Remediation project manager noted that our wipe samples verified lead levels well below HUD guidelines and we finished in record time.

15 Sponge-Jet Substrates Masonry Substrates: Granite Brick Marble Slate Sandstone Soft Metal Alloys: Cast Iron Copper Tin Bronze Carbon Steel

16 Sponge-Jet Benefits Soft substrate surface cleaning Noninvasive, low dust process protects adjacent spaces Conservator approved not to harm granite, limestone and other sensitive substrates Controlled surface abrasion Environmental stain removal Interior surface restoration Moisture-free, delicate surface treatment Environmentally friendly Safe and easy to use

17 Conclusion Use Sponge-Jet Sponge Media cleaning particles for... Low dust, soft substrate surface cleaning Controlled surface abrasion Hazardous contamination removal Interior surface restoration Moisture-free, delicate surface treatment Its environmentally friendly Its safe and easy to use
