Phosphonate Reagent 4

Overview

Phosphonate reagent 4 measure phosphonate, the scale and corrosion inhibitor that holds hardness in solution in cooling water and reverse osmosis systems. Because it is consumed by the system as well as diluted, tracking the residual is how a dosing programme is kept honest.

Key features

• Controls the antiscalant residual in cooling and RO systems
• Ready-made reagent, so there is no weighing or dilution on the bench
• Supplied in the 20 g size, item code PLpow20PPHON4

Applications

Cooling tower inhibitor programmes, reverse osmosis antiscalant dosing, closed circuits, and boiler pre-treatment.

Frequently asked questions

What does phosphonate actually do?
It interferes with the way scale crystals grow, keeping calcium and other hardness salts in solution at concentrations where they would otherwise deposit.

Does this reagent work on its own?
Several photometric methods use two or three reagents in sequence. Check which components your method lists, and we will make sure the set is complete before it ships.

How should liquid reagents be stored?
Cool, dry and out of direct sunlight, with the cap firmly closed. Note the batch and expiry on the bottle, and work through the oldest stock first.
