A novel energy recovery device/RO test rig targeted to treat & recoup low industrial wastewater flows
Cairns, Mícheál and Fitzsimons, Lorna and Delauré, Yan (2017)
In: 11th Membranes in Drinking and Industrial Water Production (MDIW) conference, 5- 8 Feb 2017, Leeuwarden, The Netherlands.
The aim of task 7.1 is to develop a system model that includes the necessary data and information required to implement tasks 7.2 Techno-Economic evaluation (viability study), 7.3 Environmental assessment and 7.4 Social assessment (Figure 1). The life cycle inputs and outputs as well as components of the treatment systems will be modelled and clear system boundaries and scenarios to be evaluated will be defined. Interactions and exchanges with external systems such as nature, energy systems and society will be included in the model. Benchmark systems will also be defined, which will serve as a reference to which the SALTGAE technology will be compared to in terms of performance.
The first task of WP1 (Halotolerant Cultures), led by FPTP, was to set-up lab-scale microalgae/bacteria systems in different saline wastewaters. Three saline wastewaters were chosen in the project framework: tannery, fishpond and cheese whey/dairy wastewaters, since the final goal of the project is to respond to the request of a wide range of industrial sectors, such as leather, food processing and land-based aquaculture.
The aim of D7.2 is to examine the environmental and economic performance of the installed demonstration sites, as well as selected algae valorization routes. The study should provide information for technology developers on the implications of design choices. A screening Life Cycle Assessment (LCA) and a Life Cycle Cost Analysis (LCCA) have been carried out to study the environmental impacts and cost incurred in the life cycle of two demonstration sites, namely KOTO in Slovenia and Archimede in Italy. Furthermore, only some valorization routes have been examined, namely composites and animal feed. A screening LCA and LCCA means that the study includes a combination of site-specific data, generic data from literature and databases, and some rough assumptions. Therefore, this deliverable is an interim report and the results presented need to be interpreted carefully. The estimated values and assumptions will be refined when further operational data from the consortium becomes available, and final conclusions will be reported in deliverable D7.3.
