Good Practice Guides for Supply of Aluminium Sulphate

Scope

This Guide covers requirements for ensuring aluminium sulphate (commonly called alum) is of a suitable quality for use in drinking water treatment.

This Guide does not cover:

• environmental protection or health and safety measures associated with the chemical including, use, labelling, storage, transportation, packaging or disposal requirements, or
• operational procedures for using the chemical.

Purpose

The main purpose of this Guide is to provide purchasers, manufacturers and suppliers with the minimum physical, chemical and testing requirements for aluminium sulphate to meet safe limits for drinking water supplies. The requirements align with requirements for drinking-water safety outlined in the Drinking Water Standards for New Zealand (Ministry of Health, 2008).
