Professional Struvite Removal with RYDLYME Descaler

RYDLYME is NSF certified, biodegradable, and safe for all common materials. Unlike harsh acids or caustics, RYDLYME dissolves struvite without damaging equipment. It’s also safer for workers and the environment while being more effective than traditional struvite removal methods.

Yes, RYDLYME is NSF/ANSI 60 certified for use in drinking water systems. It’s safe for potable water applications when used according to guidelines and properly rinsed after treatment.

Treatment time varies based on the severity of struvite buildup, but typically ranges from 2-8 hours. Light deposits may dissolve in 2-4 hours, while heavy buildup may require 6-8 hours of contact time for complete removal.

For struvite removal, we typically recommend 50-100% RYDLYME concentration. The exact concentration depends on the severity of buildup and your specific application. Our technical team can help determine the optimal concentration for your needs.

The frequency depends on your system’s struvite formation rate. Some facilities benefit from monthly treatments, while others may need quarterly or annual cleaning. Regular preventive treatment is more cost-effective than waiting for severe buildup.

RYDLYME can be applied using existing system pumps for circulation, or by using an industrial descaling system manufactured by Apex Engineering Products. Circulation pumps help ensure even distribution and faster struvite dissolution.

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. For more information on how to remove struvite, click here.

1. Obtain struvite deposit for testing with RYDLYME to confirm adequate concentration to dissolve struvite (typically 50-100%). Note the severity of struvite build-up. Obtain the current water volume of the struvite infected system as well as the designed water volume.
2. To set up a circulation, connect the circulating pump inlet to the vented container via a hose.
3. Run another hose from the pump outlet to the lowest accessible point of the struvite-infected system.
4. Run another hose from the highest accessible point of the struvite infected system back to the vented circulating container.
5. Add the prescribed amount of RYDLYME to the circulating container and turn on the pump to begin dissolving the 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 the system. Hourly monitor the RYDLYME solution to determine the endpoint. If RYDLYME is neutralized prior to the prescribed circulating duration, then more RYDLYME should be added in order to remove the 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.
