Everything that goes down the drain eventually ends up at a wastewater treatment plant. You name it and it can probably be found somewhere in the wastewater stream. Dirt, food particles, fats, oils, chemicals, and other less savory materials contaminate the water. This can cause a number of different issues for wastewater treatment facilities and the equipment involved.
For over a decade HydroFLOW has proven its ability to help wastewater treatment plants obtain the following benefits while achieving a 1-2 year payback period:
- Struvite control.
- 3% improvement in cake dryness.
- Polymer reduction of up to 20%.
- Reduced chemical usage.
- Enhanced filtration efficiency.
HydroFLOW was recognized by the wastewater industry with the WEFTEC innovative technology award.

Sample Case Studies
Wastewater Treatment Plant in St. Paul, Minnesota
HydroFLOW equipment was installed on the main centrate line at the St. Paul, MN, Metropolitan Wastewater Treatment Plant. The purpose was to determine if the HydroFLOW device could reduce the accumulation of hard struvite formation inside the pipes.
Results:
After 6 months, the pipes were given a quick water flush and then opened. As you can see in these images the results were outstanding. The remaining struvite build-up will continue to be removed during normal plant operation.
Water Reclamation Facility in Orlando, Florida
HydroFLOW equipment was installed at the Orlando, FL, Water Conserv II Water Reclamation Facility for a struvite removal and prevention trial.
Results:
After five months, a significant reduction of struvite build-up and a surprising 20% reduction in polymer use was achieved. See images of the results below.

Wastewater Treatment Plant in London, Ohio
HydroFLOW equipment was installed at the London, OH, wastewater treatment plant to determine if struvite can be removed from the belt press without chemical, manual or mechanical assistance.
Results:
The images below show the fantastic results after 35 days.

Wastewater Treatment Plant in Augusta, Georgia
The primary objective of this independent, third-party technology verification is to validate the effectiveness of the HydroFLOW i Range product with respect to controlling struvite scaling at selected test sites. The verification is based on a review of visual observations and discussion with plant staff. It focuses on identifying changes to struvite scaling before and after installing HydroFLOW units.
Results:
Following the installation of HydroFLOW and discontinuation of antiscalant, the existing scale became soft and was easily removed by spraying with high-pressure water. The observations of the plant operating staff at the WPCP are consistent with findings at other facilities where HydroFLOW has been tested.
The most significant finding with respect to site-specific performance is that HydroFLOW allowed the WPCP to eliminate the use of antiscalants chemicals and realize significant cost savings of approximately $4,000 per month.

Wastewater Treatment Plant in Denver, Colorado
The primary objective of this independent, third-party technology verification is to validate the effectiveness of the HydroFLOW i Range product with respect to controlling struvite scaling at selected test sites. The verification is based on a review of sampling data, visual observations, and discussion with plant staff, and focuses on identifying changes to struvite scaling before and after installing HydroFLOW units.
Results:
Targeted sampling during the 60-day test period included sample collection and analysis and observations of scale characteristics before and after the HydroFLOW units. Based on the review of the data and discussion with RWHTF staff, the use of HydroFLOW i Range on the centrate line was effective in softening the existing scale and preventing the formation of new scale. Softening of the existing scale allowed a substantial portion of the original hard scale to be removed during the 60-day test period, because of the shearing action of the flowing liquid.

Wastewater Treatment Plant in Tulsa, Oklahoma
The primary objective of this independent, third-party technology verification is to validate the effectiveness of the HydroFLOW i Range product with respect to controlling struvite scaling at selected test sites. The verification is based on a review of visual observations and discussion with plant staff. It focuses on identifying changes to struvite scaling before and after installing HydroFLOW units.
Results:
This Third-Party Technology Verification Report validates that the use of a HydroFLOW i Range unit at the Southside WWTP prevented scale formation in a BFP used for dewatering anaerobically digested sludge. The HydroFLOW unit also caused changes in the physical characteristics of the existing scale, making it easier to be removed.
