Crisafulli FLUMP Sludge Removal System with Pond Liner Protection System
THE WORLD'S MOST PRODUCTIVE SMALL DREDGE
When used with Crisafulli's patented Pivoting Traverse System, the FLUMP is approximately 48% more productive than competitive products. It can complete lagoon dredging projects in approximately half the time and save owners the entire cost of the FLUMP over several years from reduced operating costs.

Testimonial Municipal FLUMP
We would like to thank you for your wonderful flump. We have been dealing with our wet sludge lagoon for many years and have not always been totally successful. We found your system to be of excellent design and robust construction. The control system is direct and easy to understand.

I must say we were a little apprehensive about renting a machine, sight unseen, from the wilds of Montana, but the flump has exceeded our expectations. The setup diagrams were most helpful; however, the best part was that you were just a phone call away to answer the few questions we did have.

From beginning to end, you, your machine and the people who work for you are clearly first rate. We are looking forward to purchasing a sludge pump system and yours is certainly our first choice.

Testimonial Municipal FLUMP
"I really like the remote-control aspect of the unit. We can just have an operator sitting up here on the shore, out of the sludge, operating in a very clean environment."

"An option that we purchased for the system is the rail traverse system. We're very pleased with it; it's taken three-quarters of the work away from our dredge operator. With the touch of a button he can move it (the dredge) from one side to the other (of our lined lagoon) without even moving a step; very convenient. I wouldn't order the dredge without the rail traverse system."

"It's real easy for the operator to schedule about five (5) to ten (10) minutes once a week. That's about all the maintenance that's required." "This little electric dredge is light enough where we don't have to hire a crane to move it from lagoon to lagoon. We can rent an extended-boom forklift and get it out ourselves, instead of having to rent an expensive crane." "I'd recommend the FLUMP to most anybody. The product itself is built very well. Our new piece of equipment is doing everything that we were promised it would do. You
bet! We like this Crisafulli dredge."

Application: Solids removal from primary settling basins
Kenneth A. Dorr
Assistant Superintendent
Hanahan Water Treatment Plant
Commissioners of Public Works
City of Charleston, South Carolina

This letter is to inform you of our success using SRS Crisafulli standard duty flumps to remove settled solids from two of our primary settlings basins at the Hanahan Water Treatment Plant. The two basins were built around 1904 and had no provisions for removal of settled solids other than draining the entire contents. These basins contain approximately six million gallons each and produce twenty-two million gallons of treated water per day each. The draining of either of these units every four months caused immense loading problems for our solids handling facility, not to mention the loss of a major portion of our water production capacity. This often occurred during peak demand periods when volume and water quality were critical.

We began looking at sludge dredges but were very cautious of cutter heads that might disturb the settled solids blanket affecting water quality. Our goal was simple. Remove the solids on a continuous basis without affecting water quality and keep both basins in service while this was being performed.

We purchased a standard duty flump and removed and replaced the cutter head with a siphon manifold. We were able to remove solids at a rate of 300 to 500 gallons per minute on a daily basis without affecting water quality. Shortly, we purchased a second flump and made the same modification. The use of these two units has allowed us to solve two major problems at the Hanahan Water Treatment Plant - (a) keeping the two major basins in service while we remove solids on a continuous basis, and (b) eliminating a frequent solids loading problem enabling our solids handling facility to function as designed without overload. Now, with the use of the modified standard duty FLUMPS, we only drain the basins annually for a scheduled routine cleaning and maintenance.

We have been very pleased with the service that these units have provided and would recommend them to anyone having a similar problem.

Shown below is the City of Charleston's FLUMP with the custom siphon manifold.
