A Relationship Between Phosphate Scales and Silica Fouling in WasteWater RO Membrane Systems
In wastewater RO plants, silica keeps fouling membranes even when silica levels look safe. This study found the trigger: calcium phosphate scale acts ..
Excessive Sulfuric Acid Dosing Resulting in Irreversible Scale Formation
Dosing sulfuric acid into RO feedwater is a common “safety net,” but at this Florida plant, it backfired: the extra sulfate drove irrevers..
Optimizing Scale Inhibition Costs in Reverse Osmosis Desalination Plants
The cheapest antiscalant isn’t the cheapest way to control scale, because most of the real cost is the sulfuric acid dosed alongside it. This ca..
