PermaCare® Membrane Treatment

Antiscalants, or chemical "scale inhibitors," prevent mineral deposits from building on your membrane, causing fouling. Our PermaCare® 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 hardness. When you combine our highly effective antiscalants with our 3D TRASAR for Membranes technology, you know that the dosing always is right, not too much (which can lead to polymer fouling), not too little (which will lead to mineral scaling), but just the right amount.

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

Biofouling is inevitable in every membrane system, however, using Nalco's PermaCare biocides you can minimize the impact of biogrowth on the operation of your RO system. The right biocide program can reduce your need for membrane cleaning, reducing your overall cost of operation. Our PermaCare biocides are membrane safe and can be used online or offline.

Water pretreatment before reverse osmosis is essential to the successful operation of a membrane system. Our chemical pretreatment product line is PermaCare, and we will help you optimize your pretreatment process.

With Nalco's technologies for dose control, residuals monitoring and online optimization, your pretreatment can reach a new level of performance-where throughput is increased, frequency of cleaning and membrane replacement is reduced, and your total cost of operation is decreased.

Membrane Performance Enhancer
PermaCare® MPE™, our line of membrane performance enhancers, will, in most cases, increase your Membrane Bioreactor (MBR) throughput by 30-100%, while at the same time reducing the rate of membrane fouling.

Reverse Osmosis Automation:
More than ever before, business and industry today is faced with rapidly changing market dynamics, a fierce competitive landscape, and a constant need to improve financial performance. You can achieve potentially significant gains in operational efficiency, risk reduction, environmental performance, and capital expenditure avoidance, by harnessing the power of the worldwide web and associated high-tech products and services offered by Nalco.

Nalco's PermaCare Automation can help you optimize your membrane system, which can result in energy and water savings.
