Here are just a few of the diverse projects that FlowScience has entirely replaced Chemical, Acid and Jetting Treatment for scaling control

Greentree Landfill: Waste-Water Treatment Plant Case Study Q&A

“Keeping the water moving”; The biggest challenge was treating the daily leachate from the landfill plus outside liquids in a costly and efficient manner.  The treatment plant is a “complex critter” that renders itself by nature due to pH needed levels in the matrix to scaling.  To maintain consistent operating flow, chemicals and or manual removal of scaling was continually necessary.

A renewal NPDES permit contained new parameters which are regulated by the TMDL of the receiving discharge stream.   It was immediately recognized that meeting the new limit would require significant changes to the existing chemical treatment processes and these changes would also trigger a change in the existing O&M practices.



There were two types of scaling which need to be delt with. The first is in the landfill leachate collection/conveyance system. The other is scaling due to the treatment of the leachate.



Collection pumps were replaced, when necessary, lines were jetted as necessary in the collection system.  At the treatment plant ports are installed for acid cleaning, and processes are taken offline for cleaning. Excessive down time, equipment repair, and labor was the “norm”. Descaling chemicals were added to extend operation life between down times.


Since the installation of the FlowScience LSC equipment, we have stopped using chemical descaling additives entirely and reduced downtime for cleaning dramatically (it was a miserable job and laborers were difficult to retain). On the high pH end of treatment cost for descaling chemical ranged from $300 to $1,300 per day depending on the volume and quality of the water treated

The MSW landfill had been experiencing increased precipitation of leachate scale throughout areas of the collection system and sump pumps. Formation of scaling is becoming more rapid and has reached problematic stage. Jetting is a constant battle to keep leachate flow with chemical de-scalers being a pricey option. It was a Tuesday that I saw an article on Linkedin about a “breakthrough technology for leachate scale control”. The system used a charge to treatment pads on the outside of pipes and pumps and was guaranteed to not only inhibit but also remove leachate scaling. “Highly skeptical” is a word that would best describe my thoughts on a product like this. I would have heard of it by now…



Jetting wasn't keeping up.  Additional measures were needed to keep critical LCS and sumps flowing.  Chemical treatment was quoted several times.  $300K annual was the best quote and wouldn't guarantee that jetting wouldn't be necessary in some aspects.  This was going to hurt the operating budget


Attaching to 2 pumps that had to be cleaned almost weekly and 2 scaled lines that were in need of cleaning more frequently; we saw results in the first week. Wells and sumps were gathering a slurry and chunks of scale (much like after jetting) and the pumps look like new after many weeks of operation in the sumps. The LSC systems worked. My goal as an operator that knows the challenges of operating and MSW today is to let others know that FlowScience is completely legit and the overall benefits are tremendous. We’re greener and we’re saving costs. That’s not a common thing to have in a product.

California Landfill; 4” Force Main: Permanent Scaling Solution Project

The Landfill was experiencing consistent scaling of approximately 2200 linear feet of the lower 4” Force Main whereas jetting was required at least twice per year. The pipe itself would be approximately 50% scaled every 6 months and continual hydro-jetting was necessary to keep the critical line flowing. In some instances, areas of pipe needed to be cut out in super-saturated calcification points. The leachate scaling itself was familiar to other sites see in California by Gii Group.


SYSTEM 1: FLowScience LSC 2XL (4 treatment pads) to be attached to the 4” PVC pipeline immediately following the W119B location. Prior to beginning formation of scaling.

SYSTEM 2: FLowScience LSC 1XL (2 treatment pads) to be attached to the 4” PVC pipeline immediately following the W236 location.


Upon evaluation of the drawings and the FlowScience Landfill Design form Gii connected with the engineering and landfill OPS personnel to determine the solution to be provided to keep the Force Main scale free permanently. Taking under advisement the optional start-up solution, the line was jetted one more time prior to turning on the FlowScience Leachate Scale Control Systems. One system was added to the beginning of the line and another approximately 1200 feet downstream. Once systems were turned on, LF personnel would camera the line at regular intervals. In early February 2020 the landfill turned on two (2) FlowScience systems in hopes of keeping the line clear long term. As of mid November 2020, the 4” FM continued to flow freely with only minor surface scaling becoming apparent at each camera interval. It was determined in a Zoom meeting that this minor residual scaling build-up was 99% likely attributed to varying flow rates. Further camera inspections have shown the continued scale inhibiting results and as of February 2021 there has been no additional maintenance needed to keep the FM clear and FlowScience continues to inhibit leachate scaling along the line. Personnel will continue to monitor the line and have been advised that FlowScience LSC system lifespan is approximately 15 years. The FlowScience LSC Systems have worked and have eliminated the need to jet and cut the Force Main with return on investment of under 1-year.
