two.1.4) Short description

1.3. Phosphoric Acid is dosed for plumbosolvency control; Plumbosolvency is the ability for water to dissolve lead. To control and prevent this, the addition of phosphate is required. Continuous dosing of low levels of phosphate into drinking water causes build-up of a thin scale on the inner walls of pipework. This scale prevents water from coming into direct contact with the walls of any lead pipework. Provided that the dose is applied continuously and without interruption this scale remains in place, thereby protecting customers from any harm associated with lead in drinking water.
