Struvite Removal from pipes using RYDLYME:

RYDLYME is extremely effective in struvite removal from the piping and other affected equipment in wastewater treatment plants. The amount of RYDLYME required will be dependent on the severity of the struvite accumulation and the volume of the system to be cleaned.

Typically, RYDLYME will be applied at 50-100% depending on the thickness of the struvite deposits to be removed. The preferred method of application is to circulate the RYDLYME solution through the pipe or equipment, but it can also be effective when utilized in a static or fill and soak application.

How to remove struvite from pipes in waste water

Apex highly recommends that, prior to cleaning, you contact us for technical assistance in determining the best dilution and method for removing your struvite scale deposits.

  1. Obtain struvite deposit for testing with RYDLYME to confirm adequate concentration to dissolve struvite (typically 50-100%). Note severity of struvite build up. Obtain the current water volume of the struvite infected system as well as the designed water volume.
  2. To setup a circulation, connect circulating pump inlet to vented container via hose.
  3. Run another hose from pump outlet to lowest accessible point of struvite infected system.
  4. Run another hose from the highest accessible point of struvite infected system back to the vented circulating container.
  5. Add prescribed amount of RYDLYME to circulating container and turn on pump to begin dissolving struvite. Add water to the solution until a complete circuit is obtained.
  6. Continue circulation for 6-12 hours depending on struvite severity and volume of system. Hourly monitor the RYDLYME solution to determine end point. If RYDLYME is neutralized prior to the prescribed circulating duration, then more RYDLYME should be added in order to remove remaining struvite. (See “Testing the Effectiveness of RYDLYME”)
  7. Upon completion of the struvite cleaning, rinse the system with clean water to remove any insoluble materials that may have been released from the struvite deposit.
  8. Return the system to service.

WHAT IS STRUVITE?

Struvite is a naturally occurring crystal of magnesium, ammonium and phosphate. A primary concern at wastewater treatment plants, particularly after anaerobic digesters release ammonium and phosphate from waste material that crystalize into concrete like deposits that can form on the downstream system components. The formation occurs because you have magnesium from hard water, ammonia as a byproduct of urea and urine and phosphate from the organic matter being processed, coming together in the plant’s system to form crystals that can deposit on pipe walls as well as on other components of the treatment system.
