This research presents results from phosphate dosing experiments using a real scale chlorinated DWDS, comparing standard phosphate concentrations of United Kingdom drinking water (1 mgP/L) with a double dose (2 mgP/L) commonly used in plumbosolvency treatment.
Phosphates for potable water treatment perform several functions that include: iron and manganese control, scale inhibition and removal, corrosion control and chlorine stabilization.
Phosphates have many uses in the treatment of potable (drinking) water. They are used to prevent “red” (from iron) and “black” (from manganese) water; to prevent and/or retard scale formation (from minerals depositing) and corrosion (from low pH and/or dissimilar metals) in the water distribution system; and to reduce soluble lead and ...

To achieve passivation of new or previously untreated systems phosphate is typically dosed at > 3.0 mg/L as orthophosphate. The typical maintenance dosage to ensure corrosion control is 0.5-1.5 mg/L as orthophos-phate.
15 Δεκ 2020 · The new dosing regimen presented an opportunity to examine the impact of phosphate on developing biofilms, including mix-species microbial composition and potential functional traits, in sections of different pipe materials both pre- and post-phosphate dosing.
The following dosing table provides the "beginner" dose of Flourish Phosphorus™ for various water volumes. This table applies to bottles of 100 mL - 500 mL. Please note that the 2L and 4L bottles of Flourish Phosphorus™ have larger cap volumes than the smaller bottles.
