Permatreat 191 T

Summary

Product Identification

• Product Name: PermaTreat PC-191T
• Product Type: RO Membrane Antiscalant

Benefits

• Highly effective scale inhibitor across a broad spectrum of water qualities.
• Minimizes carbonate and sulfate scaling and cleaning costs.
• Replaces the need for acid dosing in many applications.
• Compatible with all types of membranes based on polyamide chemistries.
• Effective iron sequestrant.
• More stable and effective than sodium hexametaphosphate and most polymeric antiscalants.

Uses

• Designed for use in RO systems as an antiscalant.
• Contains patented TRASAR for optimum control on dosage to protect the system against under and overdosing.

Description

PermaTreat PC-191T is a threshold agent able to stabilize a wide range of super-saturated salt solutions. It contains TRASAR for improved reliability of scale control by assuring consistent dosing.

Dosage

The required dosage of PermaTreat PC-191T will depend on water chemistry and site-specific parameters. Your Nalco representative will recommend the optimum dosage.

Feeding

• Should be fed via a closed system.
• A closed system is defined as a system in which fluid is moved from a closed storage vessel into a treated media without exposure to the atmosphere except through normal venting or pressure relief devices.
• Should be fed continuously to minimize precipitation of scale and fouling of RO and nano-filtration membranes.
• It is recommended to operate the dosing pump with the highest possible frequency and to adjust the dosage by adjusting the pump stroke to ensure membrane protection.

Materials

Storage and application equipment (pumps and lines) should be made of PVC, PE, Teflon, or Stainless Steel. Do not use Aluminum, Brass, or Carbon steel in contact with the neat product.

Handling

• Use protective equipment such as goggles and rubber gloves when handling.
• Consult the Material Safety Data Sheet for environmental and safety information.
• Can be stored for at least 12 months from date of shipping if kept in its original, unopened container and under normal warehouse conditions.
• Protect from freezing and from exposure to high temperatures.

Notes

PermaTreat PC-191T is available in non-returnable containers and PORTA-FEED's of different sizes.
