Guidelines for deep purification of secondary effluent for non-potable reuse using biological filtration systems

Scope

This document provides guidance for deep purification of secondary effluent for non-potable reuse by using biological filtration systems in urban areas. It specifies general requirements, system selection, biological filtration system components, technical requirements of each component, water reuse applications and system design considerations.

This document is applicable to:
a) engineers that intend to implement biological filtration systems for deep purification of secondary effluent for reuse purposes in terms of design and implement, under safe and stable circumstances;
b) enterprises who assist spreading high-efficiency water reuse technology among different countries and accelerate the technological progress in the field of secondary effluent reuse.
