Hydroflow Waste Water Treatment
Two issues that are particularly problematic in the treatment of wastewater are the build-up of deposits of struvite or other scaling and the need to add expensive polymer flocculants to ensure the effectiveness of the dewatering process. The award-winning HydroFLOW® units are designed to address both these issues in wastewater from industries such as food and drink, manufacturing, and sewerage. The electronic flocculation effects of the HydroFLOW® units give substantial savings in polymer use in dewatering centrifuges and belt presses, typically over 15%.
HydroFLOW® electronic water conditioners also offer a chemical-free alternative to attacking scale such as struvite and minimizing physical interventions such as high-pressure jet washing.
Installation is simple, with no system downtime, modification, or draining required. HydroFLOW® units operate maintenance-free 24/7, providing maximum performance.
Case Study
The 2-meter wide belt presses at the City of Orlando Waste Water Treatment Plant suffered from severe struvite scale accumulation which greatly impeded the equipment’s productivity and effectiveness. They wished to prevent new struvite scale accumulation, gradually remove existing struvite deposits, and if possible, reduce polymer usage. A custom 12” HydroFLOW® was installed on the feed to the belt press.
RESULTS
There was a marked reduction in the struvite build-up and
the existing struvite was gradually removed. The amount of
polymer required to produce a cake of sufficient dryness
was reduced by about 20%.
INDEPENDENT TEST REPORT
“This technical memorandum verifies that the use of HydroFLOW® I Range units at the RWH Treatment Facility prevented scale formation in the central transfer pump and pipe. The HydroFLOW® units also caused changes in the characteristics of the existing scale, making it easy to remove the flowing liquid. It should be noted that following the test, RWHTF purchased and installed four HydroFLOW® units on the center and digested sludge lines”

OUR CUSTOMERS SAY
“The HydroFLOW® device not only reduced the rate of struvite accumulation it started to soften up existing deposits! Within a week, we started seeing large pieces coming off the first roller and the wash box. In addition, over half of the holes on the first roller were open. Within 35 days, a significant amount of the struvite in the belt press was removed.”
