Technical information on this site
Specifications, gradations and typical values published here describe our standard grades. They are indicative. The binding values for any consignment are those on the certificate of analysis issued for that production lot, which is supplied with the shipment.
The calculators and selection guides on this site are sizing aids for enquiry and budgeting. They are not a filter design and must not be relied on as one. Final layer depths, freeboard and backwash rates depend on the underdrain type, design filtration rate and target effluent quality, which these tools do not model.
Reference projects
Project profiles on this site are presented without naming the client. Where a named reference is required for a pre-qualification or tender, we will provide one with that client's written consent.
Intellectual property
The content, brand marks and design of this website belong to Aqua Tree. You may download and print technical documents for the purpose of evaluating or specifying our products. You may not republish them as your own or present them as another supplier's.
Governing law
These terms are governed by the laws of the Arab Republic of Egypt.
