Abstract

It is critical that the development of new technologies to solve environmental problems do not shift the burdens (impacts) to other mediums. Therefore, to ensure the optimum environmental design of water treatment and recovery systems, it is pertinent to apply life cycle assessment (LCA) at an early stage of development. Using LCA at an early developmental stage is known as prospective LCA and is particularly challenging due to the low data availability or quality. The aim of this study is to highlight the opportunities and challenges of using prospective LCA in the development of water treatment and recovery technologies. To do this we utilise two case studies from the EU Zero Brine project and apply LCA at two developmental stages. The treatment systems are specifically tailored for each case to treat the individual brine compositions and selectively recover its constituents. The first stage LCAs are based on laboratory experiments and engineering-based calculations, whilst the second stage assessments use improved input data from pilot plants and simulation. The paper compares the analyses of both stages, identifies key differences and discusses these disparities. In addition, it provides insights on the challenges of applying LCA for the design and development of wastewater treatment and recovery systems.

在零排放盐水处理和回收设计和开发的早期阶段使用生命周期评估
解决环境问题的新技术的发展不能把负担(影响)转移到其他媒介上,这一点至关重要。因此,为了确保水处理和回收系统的最佳环境设计,在开发早期应用生命周期评估(LCA)是有必要的。在早期开发阶段使用LCA被称为前瞻性LCA,由于数据可用性或质量较低,这尤其具有挑战性。本研究的目的是强调在水处理和回收技术的发展中使用前瞻性LCA的机遇和挑战。为此,我们利用欧盟零卤项目的两个案例研究,并在两个发展阶段应用LCA。处理系统是专门为每种情况量身定制的,可以处理不同的盐水成分,并有选择地回收其成分。第一阶段的lca基于实验室实验和基于工程的计算,而第二阶段的评估使用来自试验工厂和模拟的改进输入数据。本文比较了两个阶段的分析,找出了主要的差异,并对这些差异进行了讨论。此外,它还提供了将LCA应用于废水处理和回收系统的设计和开发所面临的挑战的见解。

期刊介绍: Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
