Sourcing guides

Water treatment sourcing guides

One practical guide for each category AquaTradeHub covers. Each explains what the category includes, which specifications to compare between suppliers, what information to send with an enquiry, and the mistakes that most often lead to the wrong purchase.

How to use these guides

The guides are written for procurement teams, plant engineers and business owners who need to buy with confidence without being specialists in every product. They are deliberately practical: each one ends in a checklist you can adapt for your own request for quotation.

Figures in the guides are widely used rules of thumb, not design values. Water chemistry, site conditions and local regulations vary, so always confirm specifications against the supplier's own data and, for anything safety- or compliance-critical, with a qualified engineer.
