Frequently Asked Questions

A : : Unlike ferric chloride, ferric sulfate, and aluminum sulfate, Green Steel PSR™ is non-hazardous, significantly reducing workplace risks, storage complexities, and environmental liabilities.

A: Green Steel PSR™ requires only a few hours of contact time to remove up to 80% of phosphorus and sulfur.

A: Green Steel PSR™ mitigates infrastructure corrosion, reduces H2S scrubbing requirements, inhibits struvite formation, raises pH balance, and can improve biosolids dewatering by up to 15%.

A: No, it requires a relatively low CapEx investment for the delivery system.

A: Yes, it’s a low-risk implementation. In the unlikely event you decide to switch back to your existing chemical treatment process, our buy-back program guarantees your satisfaction by committing to you that we will buy back the inventory of Green Steel PSR™ you purchased as well as our delivery system.

A: Absolutely, Green Steel PSR™ effectively achieves regulatory requirements for phosphorus discharge limits.

A: Yes, Green Steel PSR™ is actually environmentally beneficial by significantly reducing harmful chemical discharge, thus protecting aquatic ecosystems and promoting sustainability.

A: Green Steel PSR™ acts as a natural pH buffer, reducing the need and cost of chemical amendments for pH management.

A: Yes, by removing 80% of phosphorus, Green Steel PSR™ effectively inhibits struvite and vivianite formation in anaerobic digesters.

A: Phosphorus sequestered by Green Steel PSR™ settles into biosolids, which can be safely managed using existing SOPs.

A: Yes, Green Steel PSR™ is less expensive, reducing both chemical and operational costs associated with managing phosphorus levels in wastewater.
