Posted by Elizabeth Kaiser on Thu, Jul 14, 2011 @ 13:07 PM

SRS Crisafulli's factory location is intriguing.  SRS Crisafulli is a dredge and pump manufacturer with a factory in land-locked Eastern Montana.  "Glendive, Montana is a unique and very rural community" says SRS Crisafulli President/CFO, Laura M. Fleming. "Glendive is about as far off the beaten track as can be found in modern America. We had two visitors from Israel this week, and sent them home with special stories about Eastern Montana."SRS Crisafulli Factory Employees

"Good People Surrounded by Badlands" is a phrase promoted by the Glendive Chamber of Commerce.  "It was even a $50,000 question on Who Wants to be a Millionaire" adds Ms. Fleming.

"When I present at public speaking events, I use the phrase:  'The River is our Teacher.'  The Yellowstone River and the unique terrain in Eastern Montana created the Company - and vice versa - the people who homesteaded in this area developed unique irrigation methods and technology.  The landscape contributes to the DNA of SRS Crisafulli" says Ms. Fleming.

Photojounalist Lynn Donaldson has visited the Glendive and the SRS Crisafulli factory on several occasions.  "You may visit Lynn's Montana blog at www.placesbetweenspaces.com where you will get a taste of real Montana", says SRS Crisafulli Sales Manager Maureen Lundman.

The 28 year SRS Crisafulli veteran employee, Ms. Lundman, says "Glendive, our 'City by the Yellowstone', offers unrivalled scenery.  The mighty Yellowstone River bisects the town.  We're always watching the river."

Makoshika State Park

"Glendive is bordered by the rugged and majestic Makoshika State Park. Makoshika (Ma-ko'-shi-ka) is a variant of a Lakota phrase meaning land of bad spirits or badlands."

"Glendive is a warm & welcoming community, and a great place to live--with an excellent school system, a 2-year college, state-of-the-art medical facilities, fantastic hunting, fishing and recreation, as well as a good share of the fine arts available locally."

"SRS Crisafulli employees count themselves as fortunate to live under Montana's Big Sky!" comments Ms. Lundman.

Dredging Q+A: Top 8 Questions Answered

Posted by Elizabeth Kaiser on Wed, Jul 13, 2011 @ 19:07 PM

dredging questions and answers

 

We strive to provide our customers with as much information as they need to make informed decisions about the dredging equipment they choose.

So we compiled some of the questions (and answers!) asked most frequently for your quick review.

Q: What kinds of dredges does SRS Crisafulli make?


A: SRS Crisafulli produces hydraulic dredges with horizontal auger cutterheads in two model groups - i.e., self-propelled, steerable, operator on-board diesel powered Rotomites, and remote-controlled, cabled, electrically powered, unmanned FLUMP dredges. 


Q:  What sizes do SRS Crisafulli dredges come in?

A:  The remote-controlled FLUMP comes in two sizes:  the 3-inch (standard or  severe-duty), and 4 inch severe-duty. The Rotomote SD-110 is equipped with a 4-inch pump and six-inch discharge.

The Rotomite 6000 and Rotomite 6000C models are 6x8 (a six-inch pump with an eight-inch discharge.

Q: What is a FLUMP?


A: FLUMP stands for “Floating Lagoon Pumper”.  An operator runs the FLUMP from a hand-held radio remote control, or from a shore panel connected by wire to the FLUMP.

Q: What is a Rotomite dredge? How is it different from the FLUMP?


A: The Rotomite Dredge series includes manned (“operator onboard,”) self-propelled, steerable dredges which can operate without a support vessel.  Normally, these models are diesel-hydraulic powered, although a few are offered in all-electric customized versions.


Unlike the FLUMP, the Rotomite doesn’t require a cabled traverse system to control dredge movement.  For the customer’s convenience and to increase versatility, Rotomites are designed to operate as either cabled or free-floating (not cabled,) dredges.

Q:  How deep can I dredge with a SRS Crisafulli dredging system?


A: Dredging depths are 10 feet with a standard duty FLUMP and 12 feet with a severe duty FLUMP.  The Rotomite SD-110 will dredge up to 12 feet and the Rotomite 6000 will dredge up to 20 feet.  SRS Crisafulli's newest model, the Rotomite 6000C, reaches a depth of 23 feet.  Greater depths are available as custom models.

Q:  How much material can be dredged with a SRS Crisafulli dredge?



A:  FLUMPs can dredge 25 to 80 cubic yards of settled solids per hour and Rotomites can dredge up to 150 cubic yards of settled solids per hour.

Q: How far can the dredged slurry be pumped without a booster pump?


A: Typically, Crisafulli dredges will pump slurried material up to 1,500 feet, depending on the site conditions and the slurry.

Q: What is a good application for a Crisafulli dredge? Is it right for my needs?


A: SRS Crisafulli dredges are installed in some of the world’s most demanding environments, and dredge a wide variety of materials in both industrial and municipal settings.


SRS Crisafulli dredges are frequently used in the following applications:


-Residuals from potable water treatment plants
-Biosolids from wastewater treatment plants
-Runoff ponds, basins and lagoons
-Mines (for the management of tailings)
-Power plants (for fly ash ponds and sedimentation ponds
-Refinery and petrochemical wastes
-Processing plants (Food processing; Rendering; Slaughterhouses)
-Metal processing wastes
-Chemical sludges
-Marina and canal maintenance

Dredging Abrasive Materials? Learn about SRS Crisafulli’s New Dredge

Posted by Elizabeth Kaiser on Fri, Apr 29, 2011 @ 06:04 AM

dredging abrasive materials rotomite 6000cThe Rotomite-6000-C, SRS Crisafulli’s newest self-propelled dredge, broadens the Rotomite-6000’s capabilities to include removal of highly abrasive materials. The Rotomite-6000-C also increases the customer’s return on investment (ROI) by cutting sludge management costs, increasing user productivity, and enhancing the unit’s maneuverability for the removal of toxic and non-toxic solids.

The new design offers capabilities that will benefit industrial companies, including; chemical companies, food processing plants, domestic and international construction and contracting companies, oil, mining and refining companies, petrochemical plants and refiners, and coal fired utility companies. Municipalities, County, Regional and Federal agencies, as well as lake associations, and landfill operators, will be able to use the Rotomite-6000-C in many applications. In addition, the Rotomite-6000-C helps companies comply with domestic and foreign mandates by ensuring manufacturing by-products are contained safely in order to prevent contamination of drinking water.

This versatile, self-propelled design is a horizontal auger, hydraulic dredge that can work in odd-shaped areas where a cable dredge unit cannot go. It can remove, pump and discharge dredged solids in water/solids slurries through a floating discharge pipe to disposal sites up to 5,000 feet away, or more when a booster pump is used.

The Rotomite-6000-C is 40 feet long by 9.5 feet wide, and is easily transported by truck.  Its 255-horse power motor and new propulsion system provide increased production and propulsion thrust. It will dredge most soft or abrasive materials, including alum and lime sludges, bentonite, biosolids, bottom ash, clay, coal fines, fly ash, gypsum, mine tailings and slimes, mill scale, mud, pigmentation sediments, industrial and municipal wastes, pulp and paper residuals, peat, oil API sludge, sediments silt and sand.


Capabilities include:

  • Dredging depth of 23 feet standard (up to 30 feet optional)
  • Up to 235 cubic yards of sludge solids produced hourly
  • A discharge volume of up to 3,400 gallons per minute @ 180’ TDH (water)
  • A dredging speed of up to 25 feet per minute
  • A dredging cut up to 8.5 feet wide
  • A cutterhead torque of 11,500 inch/lbs.
  • A draft of 30 inches

The self-propulsion feature provides increased maneuverability, more forward and reverse speeds and a 72-horse power hydraulic motor that powers a propeller system capable of 2,500 pounds of force. SRS Crisafulli’s exclusive Cobra cutterhead, which provides 11,000 inch-pounds of digging torque and up to 235 cubic yards of sludge solids per hour, increases productivity. The hydraulic ladder results in enhanced downward force by providing 30,000 pounds of down pressure to dig into the settled solids materials more aggressively thereby increasing cutting capacity. An improved cab design provides operator safety and convenience features, including air conditioning and heating.

How Marinas Benefit From Scheduled Dredging

Posted by Elizabeth Kaiser on Fri, Apr 15, 2011 @ 08:04 AM

dredging marinas - SRS Crisafullidredging marina - srs crisafulli

Scheduled dredging enables marina owners to increase their profits and minimize their environmental impact.

 

The purpose of this article is to highlight the importance and value of scheduled dredging for marinas.

Maintaining adequate water depths in each boat slip and on approaches to marinas at low tide is essential to attract and keep the largest yachts in the regional market – yachts that generate the largest marina fees.

Without regularly scheduled dredging, marinas can be temporarily forced to close their slips for their best paying customers. Dredging just part of a marina can have costly and adverse environmental consequences in tidal areas by accelerating silt build up in slips for larger boats, and compromising water flows and drainage throughout the marina.

Environmental issues are more complex and include:

• Protection of water quality and marine life.
• Protection of docks, slips, and boats.
• Removal and disposal of clean sediment.
• Removal and disposal of contaminated sediment.
• Traffic, noise, and odors disturbing neighbors.

Since sediment build up is ongoing and predictable, a dredging schedule should be seriously considered. Key benefits of a dredging schedule include: 

• A budgeted expense rather than an unpredictable cost.
• Uninterrupted use of the marina.
• A reduction in problems caused by the permitting process often related to sediment disposal.

Most experts recommend dredging at two or three year intervals.
