Phosphates for potable water treatment perform several functions that include: iron and manganese control, scale inhibition and removal, corrosion control and chlorine stabilization.
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.
The appropriate volume (see table above) should be administered over 24 hours, but can be given more quickly (over a minimum of 6 hours) if required, providing this can be safely tolerated by the patient. Repeated doses may be required on subsequent days after checking of serum phosphate levels.

Doses for intravenous phosphate vary in the literature and suggested regimens have included weight based dosing regimens of 0.2-0.5mmol/kg/day up to a maximum of 50mmol. WAHT-PHA-011

A common dose is 1 - 2 tablets three times a day (6). The dose should be reviewed daily and adjusted according to phosphate levels (6). Oral phosphate supplements should not be taken with aluminium, calcium or magnesium salts as these will bind phosphate and reduce its absorption (5).
