Deliverables
HIM imaging study of CNM-composites, which contains optimized imaging conditions for verifying successful preparation and homogeneity of the free-standing CNM within the track-etched pores of the support. In addition, sample preparation protocols and imaging conditions for characterizing bended CNM-composites will be given.
Results of stability tests of CNM-composites (opens in new window)Report on the stability of up-scaled CNM-composites by laboratory tests, which address fouling behavior and time-depended performance measurements.
Bench-marking CNM-based UPW with state-of-the-art (opens in new window)Lab-scale systems and pilot-scale systems with implemented CNM-composites with optimized operating parameters for pressure driven polishing will be compared with state-of-the-art. This includes evaluation of pre-treatment steps, module staging, flow speed, and recovery rate.
Tool for modelling systems and semi pilots fully functional (opens in new window)Report on the development of a tool evaluating the filtration rate and associated power consumption of complex filtration systems, based on the system design, feed water characteristics, membrane characteristics and operating conditions. The tool will be based on a modular concept, through which system elements, such as filtration modules or pumps, are assembled to build a virtual model of a filtration system.
Results of coupon testing with CNM-composites (opens in new window)Report of coupon testing of CNM-composites in filtration cells. Experimental setup: membrane holder, spacer, hydraulics, water type, analytics of CNM-composite.

Improved design model for flux and separation optimization (opens in new window)Description of an improved design model, which rationalizes the results of the experimental work. Based on the transport measurements, we will model the pore size distribution in CNMs and compare it with the structural data available. Most efforts will be put to understand the separation mechanism of CNMs for different aqueous media (Size exclusion, Donnan’s effect, and dielectric mechanism as a function of solutes nature). Undesired phenomena such as concentration polarization will be addressed as well.
Design model for mechanical stability optimization (opens in new window)Description of a design model, which links the role of CNMs’ micro- and nanoscale structure on their mechanical performance for tensile and compressive loading as well as fracture toughness (dry and wet). Identification of critical structural and loading conditions for performance, temperature effects (creep, weight loss). Multilayered CNM structures will be also studied and their fracture behavior will be examined to finally define the best number of layers for better mechanical resistance without permeance tradeoff. The minimum support thickness for efficient separation will also be determined. The scalability of the results will be investigated, to correlate the mechanical performance with the desired scale up dimensions.
Results of permeation experiments with single-component (opens in new window)Report on permeation experiments with single-components (gas, organic liquids). We test a variety of CNMs regarding their water permeance and selectivity in cup tests and entrance effects for track-etched supports. We further explore effects of the size of components, temperatures, multilayered behavior as well as solubility of components in water by performing permeation experiments with single-components (gas, organic liquids). Furthermore, we will use a dedicated custom-made liquid cell in a standard biophysical electrophysiology setup to determine the transmembrane ionic resistance of the CNMs. We will explore the effects of ion polarity, size, salt mobilities, temperature, as well as solubility by performing permeation experiments with salt solutions.

Manual for analyzing structure and composition of CNMs (opens in new window)The most effective strategies for analyzing CNMs will be reported. Currently, Atomic Force Microscopy (AFM) is the only method for a quantitative measure of the sub-nanometer-sized nanopore network in CNM. We will use and develop this technique for a characterization and quality control of the CNM surface morphology in vacuum, ambient and water environment. In addition, Helium Ion Microscopy (HIM), X-Ray Photoelectron Spectroscopy (XPS), Infrared and Raman Spectroscopy will be considered as part of the analyzing strategy.
Study about cleaning of CNM-composites (opens in new window)Study about cleaning of CNM-composites: We evaluate anti-fouling strategies of CNM-composites with existing cleaning technologies. Examining biofilm formation is planned with SEM, FISH, ATP, and cell counts.
Concepts for optimized module design (opens in new window)Concepts for optimized module design: We investigate the optimal CNM module design to be used in full application. Design requirements such as the need for easy cleaning, high packing densities, cost effective operation and membrane replacement, appropriate flow pattern to reduce internal and external concentration polarization both for FO and RO; Spacer requirements, anti-scalants, cleaning procedures.
Results of permeation experiments with mixtures (opens in new window)Report on permeation experiments with mixtures of water and other components. We test a variety of CNMs regarding their water permeance and selectivity in cup tests and entrance effects for track-etched supports. We further explore effects of the size of components, temperatures, multilayered behavior as well as solubility of components in water by performing permeation experiments with mixtures of water and other components. We will use a dedicated custom-made liquid cell in a standard biophysical electrophysiology setup to determine the transmembrane ionic resistance of the CNMs. We will explore the effects of ion polarity, size, salt mobilities, temperature, as well as solubility by performing permeation experiments with aqueous mixtures of ions and other components
Module simulator is operational (opens in new window)Report on the development of a module simulator for long-term testing of modules/cassettes (in particular for determining the fouling behavior). The results from Task 3.1 will be used to develop a module simulator, which than will be used in semi-pilots to tests applicability of CNMs. This development includes the integration of membranes with spacers into module simulators as well as protocols for material analysis of used modules/membranes.

Comparison of alternative supports vs. track-etched supports (opens in new window)Comparison of alternative supports vs. track-etched supports. Several alternative supports will be explored to achieve CNM-composites which preserve the benefits of pristine CNMs and enhance their ability to withstand mechanical stress during operation. These pathways include the use and optimization of polymer membranes as well as photolithographically patterned support structures. The performance of the most promising supports will be compared with track-etched supports.
