PermaCare® Membrane Treatment Chemicals

Nalco's Utilities & Membranes Solutions team has a three-part programme of service, products and equipment to maintain and enhance membrane performance. Whether you're exploring our chemical membrane product offerings for the first time or you're already familiar with them, we'll work with you to find the right solutions.

Antiscalants

Antiscalants, or chemical "scale inhibitors," prevent mineral deposits from building on your membrane which can cause fouling. Our PermaTreat® product line helps resolve these problems and, in almost every instance, at a lower cost than it would be to use ion exchange to remove the troublesome hardness salts. When you combine our highly effective antiscalants with our 3D TRASAR® for Membranes technology you know that the programme dosage level is always right - not too much (which can lead to polymer fouling) and not too little (which will lead to mineral scaling) but just the right amount.

Cleaning Products

When a membrane does need cleaning, our PermaClean® chemical product line removes most foulants and restores performance in all types of membrane systems. We can provide you with cleaners specifically formulated to remove mineral scale, insoluble scale, organic fouling or microbial residue.

Biocides

Biofouling is inevitable in every membrane system, however, using Nalco's PermaClean® biocides you can minimise the impact of biogrowth on the operation of your reverse osmosis system. The right biocide program can reduce your need for membrane cleaning and thereby reduce your overall cost of operation. Our PermaClean® biocides are membrane-safe and can be used either online or offline.

Pre-Treatment

Appropriate pre-treatment of water before it contacts a reverse osmosis membrane is essential to the successful operation of the membrane system. Our chemical pre-treatment product line is PermaFloc® which will help you optimise your pre-treatment process.

Membrane Performance Enhancer

PermaCare® MPE™ is Nalco's range of membrane performance enhancing programmes. PermaCare® MPE™ programmes can increase your membrane bioreactor (MBR) throughput by 30-100% whilst simultaneously reducing the rate of membrane fouling.
