Oxygen Depletion: Overdosing SMBS can deplete dissolved oxygen in receiving water bodies, creating a hazard for fish and aquatic ecosystems.pH Drop: The chemical reaction creates acidic byproducts (HCl).
This can lower the pH of the treated water, often requiring a neutralizing agent like sodium hydroxide afterward.Gas Release:
If SMBS solutions come into contact with acids, they release hazardous sulfur dioxide (SO2) gas. Proper ventilation and PPE are mandatory during handling.
