From wastewater to resource

Eighty percent of wastewater is left untreated or not reused, exacerbating the water quality challenge, especially in vulnerable communities. This Voices asks: how can we improve wastewater management and convert wastewater into a resource?

OSiD: opening the conceptual design of biobased processes to a context-sensitive sustainability analysis

Biobased production has been promoted as an alternative to fossil-based production to mitigate climate change. However, emerging concerns over the sustainability of biobased products have shown that tensions can emerge between different objectives and concerns, like emission reduction targets and food security, and that these are dependent on...

A techno-economic analysis of membrane-based advanced treatment processes for the reuse of municipal wastewater

The objective of this paper is to compare, under Dutch market conditions, the energy consumption and net costs of membrane-based advanced treatment processes for three water reuse types (i.e. potable, industrial, agricultural reuse). The water source is municipal waste-water treatment plant effluent. Results indicate that the application of...

Exploring resource recovery potentials for the aerobic granular sludge process by mass and energy balances - energy, biopolymer and phosphorous recovery from municipal wastewater

Municipal wastewater cannot any longer be perceived as a waste stream because it contains water, energy, fertilizer and other products that can be recovered with innovative technologies in so called ‘water resource factories’. Therefore a paradigm shift has been proclaimed to design water resource factories in the future that feed into a...

The SPPD-WRF framework: A novel and holistic methodology for strategical planning and process design of water resource factories

This paper guides decision making in more sustainable urban water management practices that feed into a circular economy by presenting a novel framework for conceptually designing and strategically planning wastewater treatment processes from a resource recovery perspective. Municipal wastewater cannot any longer be perceived as waste stream...
