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!

How to clean up a flood damaged Golf Course

Posted by John Zuccerella on Tue, Apr 09, 2013 @ 10:04 AM

In an article written by Jeff Kolpack of Inforum, the Forum of Fargo and Moorhead, SRS Crisafulli makes news for helping the Fargo Park District plan for quick removal of anticipated flood waters at the Edgewood Golf Course, an 18-hole, par 71 Championship course beautifully located along the Red River - the very same Red River that is likely to jump it's banks.

“Enlisting the help of a small army… to fight a flood.  A very small three-piece army known as Crisafulli water pumps.”

describe the image

Over a year ago, the Fargo Park District made an investment in three Crisafulli trailer pumps to empty a basin of their golf course which floods when the Red River reaches the 30 foot flood stage.  Rather than waiting for the water to drain naturally, the District made the decision to purchase three Crisafulli water pumps. What they didn't expect was how effective the pumps would be. If the course can open weeks ahead of schedule, golfers can hit the course sooner,  enabling the District to realize a sooner than expected return on investment.

Overcoming Challenges in the International Dredge Market

SRS Crisafulli, Inc. ships a shallow draft dredge to Manila, Philippines to ring in 2013

CIMG1511comp

After a year of close collaboration with the customer, SRS Crisafulli’s versatile resources in both engineering and manufacturing resulted in shipment of a Rotomite SD-110 shallow draft dredge to Maynilad Water Service in the Philippines.

Three Philippine firms played key roles to close the deal – i.e., Maynilad Water Services, a private water and wastewater provider for the 17 cities and municipalities that comprise the West Zone of the greater Metro Manila area, WaterKonsult Equipment and Service, Inc., a leading equipment and service supplier serving Maynilad and many other Philippine water utilities and water districts, and SRS Crisafulli’s authorized Factory Representative, Ramoncito “Chito” Manaois, of RFM Machinery & Equipment Corp. of Manila, Philippines.

In February of 2012, Waterkonsult contacted SRS Crisafulli through SRS Crisafulli’s website.

Maynilad Water Service needed to remove sediment at its La Mesa Treatment Plant 1.  The sediment-bearing water comes from the Angat Dam and travels more than 30 kilometers to the plant. The river also carries silt to the treatment plant where sludge is collected at the bottom of sedimentation basins. To achieve acceptable, sustained settled water quality and to comply with environmental regulations, La Mesa Treatment Plant 1 must clean its sedimentation basins twice a year.  Cleaning the basins twice a year will preserve basin capacity and water quality.

Waterkonsult learned of Maynilad’s bid offering and contacted SRS Crisafulli. Waterkonsult, in association with Crisafulli’s Philippine sales representative, asked SRS Crisafulli for detailed product specifications for the Rotomite SD-110 dredge, and what makes the Rotomite SD-110 a superior dredge.  

Over the next several months, personnel from Crisafulli, Ramoncito, and Waterkonsult collaborated with Maynilad, answering requests for more information on the Rotomite SD-110. After satisfactorily answering all the requests, the Rotomite SD-110 dredge was selected. The winning SD-110 package offers a high-performing dredge pump able to move 1500 gpm at 80ft TDH in water.  The cutterhead has a 90-inch by 15-inch opening for high sludge production. The hydraulic thruster enables the dredge to be driven like a boat.

On December 31, 2012, the Rotomite SD-110 left SRS Crisafulli’s Factory headed for Manilia for delivery in February 2013. Pursuant to SRS Crisafulli’s superior worldwide service, a SRS Crisafulli Factory-trained engineer will travel to Manila to support the installation and to commission the Rotomite SD-110 dredge.

Stay tuned…
