RO Antiscalant PA0100

1 product review
Product Description

When it comes to troubleshooting reverse osmosis membranes, identifying issues that cause increases in pressure or decreases in product quality can be very difficult. The great thing about PA0100 is that it solves a number of problems simultaneously, saving you headache and preserving your reverse osmosis membranes. As a general cleaning and quality enhancing purification product, antiscalant is the go-to problem solver that ensures the quality and productivity you deserve.

PA0100 is a great product that can be used on almost any water without needing to pay for a water chemistry report. For small systems treating less than 150 gpm feed, we suggest 3-5 ppm doses to begin. PA0100 is also an excellent choice for larger systems with good pilot test results or stable operating history.

Pure Aqua’s PA0100 Antiscalant Chemicals offer superior quality performance characteristics over a range of applications. The antiscalant chemical from Pure Aqua, Inc. is designed to eliminate scale and reduce fouling in membrane systems. Pure Aqua, Inc. PA0100 is a liquid antiscalant/dispersant blended to inhibit scale and disperse colloidal particles in cellulose acetate and thin film membrane separation systems. The formulation has been certified by the National Sanitation Foundation (NSF) under ANSI/NSF Standard 60 for use in producing potable water.

Dosing Guidelines

The typical dosing range for antiscalant is between 2 to 10 ppm. If dilution is required, PA0100 should be diluted with de-mineralized water or RO permeate. If neither of these water sources is available, softened water may be substituted. The dilution for PA0100 should not exceed 10% by weight.
