Membrane Antiscalants

What is an Antiscalant?

An antiscalant is a pre-treatment solution introduced into the feedwater passing through the RO membrane to inhibit scaling. Scaling on RO membranes arises from the accumulation of particles, which obstruct the membrane's pores.

Various substances contribute to membrane fouling and scaling, such as calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, iron, colloidal material, silica, and diverse organic contaminants.

Nero recommends incorporating an RO membrane antiscalant into your pre-treatment regimen. This addition aims to enhance effectiveness against a wide spectrum of substances that cause scaling and to maintain fouling materials in suspension.

Nero antiscalants program is specifically crafted to notably minimize scale buildup and fouling in membrane systems. The antiscalants within this program are not only suitable but also highly effective across a variety of feedwater sources, encompassing brackish, waste, and seawater.
