What is a polyacrylamide standard?

This Standard covers the supply of polyacrylamides for use in the treatment of water for drinking-water supply. The main purpose of this Standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for polyacrylamides including physical, chemical and testing requirements.

Do polyacrylamides contain impurities?

2.3.1.1 The polyacrylamides supplied according to this Standard shall not contain any impurities that when dosed into water in accordance with accepted water treatment practice, may be deleterious to health or aesthetically objectionable as determined by NSF Standard 60 (DWSNZ)1 and the Drinking-Water Standards for New Zealand.

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a polymer water treatment agent that has a wide range of applications in the pharmaceutical industry. This article will introduce the overview and product characteristics of polyacrylamide, and focus on its application methods, precautions, and summaries in the pharmaceutical industry.

Are polyacrylamides safe for drinking-water treatment?

A guide audit checklist has been included as Appendix C to this Standard. Commercially available polyacrylamides for the purpose of drinking-water treatment are not known to contribute significant quantities of contaminants that adversely affect the potability of drinking-water.

How do I certify a package of polyacrylamide?

Each package shall be marked legibly with ‘Polyacrylamide’, and the following information: Packages shall have the appropriate labelling for NSF Standard 60 (DWSNZ) certification, and also be clearly labelled with the words "Complies with the NZWWA Standard for the Supply of Polyacrylamides for Use in Drinking-Water Treatment".

Why is polyacrylamide used in pharmaceutical industry?

The application of polyacrylamide in the pharmaceutical industry has significant value, as its good biocompatibility, film-forming properties, and separation effect make it a key polymer material in this field.
