Harlem Sludge Removal Project - a Montana working holiday

Posted by Troy Fercho on Tue, Jul 16, 2013 @ 10:07 AM

By Laura Fleming, President

For those of you who are following the Harlem Sludge Removal project, after several rain delays, the job is finally scheduled to proceed.  The job is setting up this weekend, (July 20th) and will run approximately 2 weeks.  The assignment is to dredge municipal sludge into a Geotube on site for dewatering into at least 75 dry ton of cake.

As reported here earlier, our electric remote controlled dredge - The Flump - will be used in conjunction with Tencate Geotubes and WaterSolve's flocculants to decant and dewater 35 years of sludge from this small Wastewater Treatment Plant three lagoon system.

The training associated with this installation - 2013 Sludge Removal for Small System Wastewater Operators Workshop - was presented by Wastewater Technician Dan Kramer, Randy Wilcox of WaterSolve, and Alan Juncker of Tencate on June 6th.  SRS Crisafulli's Chad Schipman gave a presentation on this history of the Crisafulli sludge removal systems product line.

Graduating class WWTP operators training, Harlem, MT

The graduating class:  Montana Rural Water Association offered Continuing Education for participants in this half day demonstration and training at the Harlem City Hall.

Harlem Montana is on the high-line of Montana's Rte 2.  The Amtrak train stops on either side of Harlem - in both Havre and Malta.  If you'd like to visit the jobsite by train, we will meet you.  You'll be 4 hours east of Glacier National Park - another stop on the Amtrak line.  Pack your bag for a summer hike, and you have yourself a holiday.

We know there are plenty of small wastewater systems out there that operators must desludge.  We welcome visitors to this jobsite to see how it's done.  Seriously, SRS Crisafulli and our partners on this project are making great efforts to educate and demonstrate the most common strategy Wastewater lagoon operators can deploy to maintain compliance, and a long lasting lagoon system.

To schedule an appointment at the job-site, please call the Glendive offices of SRS Crisafulli, Inc., at 406 365 3393, or phone direct to SRS Crisafulli Dredge Rental Manager, Troy Fercho at 612 419 9312.

Training: How to Remove Lagoon Sludge and Improve WWTP Outcomes

Posted by John Zuccerella on Tue, May 28, 2013 @ 13:05 PM

What should you do when your town is under multiple and ongoing consent orders for violations of its Montana Pollutant Discharge Elimination System (MPDES) wastewater discharge permit?

By Laura Fleming, President

Excessive lagoon sludge accumulation contributes to the poor performance of any treatment system, particularly in winter.  Removing sludge from the lagoon cells will improve treatment at the facility and help to address some of the violations in the Department of Environmental Quality (DEQ) enforcement action. 

The City of Harlem, Montana has a wastewater treatment system consisting of a three cell partially mixed aerated lagoon system constructed in 1985.  The lagoon system discharges to the Milk River under wastewater discharge permit MT0021270. The sludge removal project is the initial step in a comprehensive facility upgrade for the City of Harlem.

Stahly Engineering & Associates, Bozeman, MT and City of Harlem staff conducted a lagoon survey in December 2009.  Each cell was sampled in multiple locations using a sludge judge probe assembly operated from a small boat.  Solids volumes were calculated using the lagoon bottom area multiplied by the sludge depth.  A volume allowance was added for solids accumulated along the sloped sides.  The aerated ponds contain significant quantities of settled solids 1 to 2 percent in concentration and occupy between 27 and 58 percent of available volume.

Jim Bridges, a Geotube distributor doing business as Clearwater Dewatering, in Nampa, Idaho, brought together a number of parties to collaborate on the City of Harlem’s Sludge Removal Project and turn it into a training opportunity.

WaterSolve, LLC, a national leader in dewatering operations located in Caledonia, Michigan, and a master distributor of TenCate GeoTube® products bid the project. The project is financed by a grant from the Renewable Resource Grant and Loan (RRGL) program of Montana’s Department of Natural Resources.

A subcontractor to WaterSolve, SRS Crisafulli, Inc., Glendive, MT, a manufacturer of sludge removal dredge systems, will be providing the dredge, float line, and operator/trainers to this two week project, located 270 miles northwest of the Glendive factory, just the other side of the Charles M. Russell National Wildlife Refuge.

Montana Rural Water System’s Dan Kramer has qualified a training program, Sludge Removal for Small System Wastewater Operators Workshop, as a Continuing Education Credit (.35 CEC's)for Montana Certified Operators, approved by the Montana DEQ.  He is offering training at the jobsite with presentations at City Hall.  The training will be offered on  Thursday, June 6th, 2013.  Training is geared towards small and medium sized wastewater systems.  The training will provide information about the importance of the Notice of Intent, daily monitoring of equipment calibration and operation, a discussion of sludge removal, and the on-site demonstration of the working sludge removal system.

Presentations at this one-day seminar will be conducted by Dan Kramer, Wastewater Technician, and Randy Wilcox, P.E., Technical Sales Manager of WaterSolve. Representative Alan Junker from Tencate, and Ryan Rittall of Stahly Engineering will participate in a roundtable discussion. This program is open to all wastewater operators and is eligible for 0.35 CEC’s. The seminar will cover the problems facing many wastewater treatment lagoon facilities.

This specific project involves the removing of approximately 75 tons (dry weight basis) of lagoon solids from up to three treatment lagoons and pumping to a gravity dewatering system consisting of polymer addition and gravity dewatering bags.  All systems are designed by the contractor and all dewatering bags will be left on site.

If you are interested in attending, please contact Dan Kramer at techman@ronan.net.

We look forward to see you in Harlem!

SRS Crisafulli Asks "What is Coagulation and Flocculation?"

Posted by Elizabeth Kaiser on Wed, Oct 17, 2012 @ 15:10 PM

By Laura M. Fleming, SRS Crisafulli President/CFO

What is coagulation and flocculation, and why does it matter?

Last week, SRS Crisafulli hosted a bucket demonstration of Tencate Geotube technology, presented by Gregg Lebster of WaterSolve, from Grand Rapids, Michigan, and Jim Bridges, of Clearwater Dewatering, from Nampa, Idaho.

These relationships were renewed last summer when SRS Crisafulli's Australian Dealers, Bill Kelly and Andrew Cochran, made a visit to the factory in Glendive.  Over a few beers and dinner at the Lion's Club A-Frame in Makoshika Park, we discussed Dredging Solutions' successes using Geotubes to dredge and dewater sludge from wastewater treatment lagoons. Feeding the Geotubes with their Crisafulli Flump dredge system, Dredging Solutions has accomplished biosolids of >25%.

Bill Kelly explained the art of the Geotubes in his fine Aussie manner.  In particular, Bill emphasized the science of chemical conditioning regimes to flocculate the sludge.  We had homework to do - we're a mechanical engineering outfit, not chemical engineers. 

Crisafulli dredge systems have been installed in over 30 wastewater treatment facilities, including most recently an award winning system at Natchez, Mississippi, as well as the Wastewater Treatment plants in places such as Lompoc Regional WWTP, California, the Douglas County Sewer in Zephyr Cove, Nevada, the City of Mandan, North Dakota, and the City of Bozeman, Montana.  

The communitites of Glendive and West Glendive - here in rural Eastern Montana - have 90 acres currently in lagoons, and the communities are in the process of evaluating how to address the current and future wastewater needs. 

You can't blame us for wondering if we could be of any assistance to local public works departments.

We turned to Rosa-lee Cooke, Water/Wastewater Instructor at the Mountain Empire Community College, Big Stone Gap, Virginia, who offers an online curriculum in Water and Wastewater Treatment Technology, and an Associate in Applied Science Degree with a Water/Wastewater Specialization for some background. 

"In theory and at the chemical level, coagulation and flocculation is a three step process consisting of flash mixing, coagulation and flocculation.  The primary purpose of the coagulation/flocculation process is the removal of turbidity from the water.  Water with little or no turbidity will be clear."

"The end product of a well-regulated coagulation/flocculation process is water in which the majority of the turbidity has been collected into floc, which is clumps of bacteria and particulate impurities that have come together and formed a cluster."

Time for the bucket demonstration:

  1. We collected buckets of sludge from the West Glendive sewage lagoon.

  2. We vigorously mixed the sludge.

  3. Gregg Lebster prepared a selection of coagulant chemicals to add to the sludge.

  4. We mixed the coagulant with the sludge to create floc - which was then poured through a small geotube fabric sample.

    Dan Kramer, from Montana Rural Water Systems, Great Falls, Montana inspected Gregg's floc, and the clear water that had separated from the sludge.

  5. Later in the day, we repeated the demonstration at the fire hall.  Our improvisations resulted in a small geotube - held here by Ed Trainer, Geotube marine and coastline market manager, filled with fresh floc.

We hear from people in the field that many communitities are being encouraged to build mechanical plants;  we also hear that mechanical plants are both labor and energy intensive, and that the passive, non-energy intensive lagoon system may yet have more useful lives.
