Problem
Wastewater treatment facilities rely on hazardous chemicals such as ferric chloride, ferric sulfate, and aluminum sulfate to remove phosphorus and sulfur, creating safety risks, high storage costs, and environmental liabilities while driving up operational expenses.
Solution
Green Steel Environmental offers Green Steel PSR™, a non‑hazardous, steel‑manufacturing residual‑based reagent that removes up to 80 % of phosphorus and sulfur within a few hours of contact. The product reduces corrosion, lowers hydrogen sulfide scrubbing needs, and acts as a natural pH buffer, improving biosolids dewatering and inhibiting struvite and vivianite formation. Implementation requires only modest capital for the delivery system, and the company provides a buy‑back guarantee to mitigate adoption risk. By replacing traditional chemicals, Green Steel PSR™ helps plants meet stringent discharge regulations, cut chemical and operational costs, and lower workplace safety and environmental exposure.
Target Audience
Primary customers are municipal and industrial wastewater treatment operators seeking safer, cost‑effective chemical alternatives for phosphorus and sulfur removal.
