SafeGuard H₂O Delivers A Sustainable Phosphate Removal Solution For Wastewater Treatment Facilities

To reduce dependence on imported bulk chemicals, minimize carbon footprint and ensure final effluent discharges are within regulatory limits, wastewater treatment facilities can benefit from the SafeGuard H₂O phosphate removal system. The novel technology, manufactured by AMS, generates a ferrous/ferric reagent in-situ via an electrolytic process, providing a sustainable and effective approach to phosphate removal.

Two of the most significant benefits of SafeGuard H₂O’s electrogenerated ferrous/ferric reagent over traditional bulk reagents are:

1. It is produced on demand, which avoids high volumes of bulk reagent shipping, storage, and handling; and
2. It offers a flexible treatment reagent dose and pH optimization during the ferrous to ferric conversion, which allows for better pH control of the effluent.

The in-situ electrogenerated ferrous/ferric reagent, produced by the SafeGuard H₂O system, as a stand-alone treatment or in a blended ratio with bulk ferric chloride, has been proven in multiple bench-scale demonstrations to have repeated success removing phosphate.

Phosphate Removal Demonstration
A fully automated SafeGuard H₂O bench-scale 5.0 mL/min system was installed for demonstration at a wastewater treatment facility that uses bulk ferric chloride to support their phosphate removal needs. The main objectives were to:

• Show the ability of the electrogenerated ferric reagent produced on demand to effectively reduce phosphate levels discharged from the facility;
• Evaluate the performance of the electrogenerated ferric reagent (“as is” and pH adjusted) against the bulk ferric chloride water treatment chemical; and
• Determine the performance and effectiveness of an electrogenerated ferric reagent/bulk ferric chloride reagent blend for phosphate removal.

The demonstration has shown the in-situ electrogenerated ferrous/ferric reagent produced by the SafeGuard H₂O system can be used for stand-alone treatment or in a blended ratio with bulk ferric chloride to provide effective phosphate removal.
