Belloni, C. (author)
This thesis focuses on recycling resources while preserving water quality and availability. This concept is at the basis of a healthy and sustainable society yet works needs to be done. Water scarcity will be a growing challenge that humanity will have to face in the coming years, due to poor resource management and the climate change crisis....

A large number of studies on Narcissus, a member of the Amaryllidaceae family, have been published. In particular on Narcissus species, their alkaloids content, their structures including with MS-fragmentation patterns, their preparative extractions, and the analysis of these compounds covering GC-MS, LC-MS, HPLC-DAD, as well as 1H-NMR have been...

The use of Lignocellulosic residues (LC) such as conventional food crop remains, for Bioenergy and Biorefinery applications is an attractive way to increase feedstock availability without the investment in additional land area. Moreover, it is noteworthy that biomolecules produced from LC, namely second generation (2G), has a potentially better...

During the past few decades, numerous protein-based pharmaceuticals to treat chronic and life-threatening diseases have emerged. The short plasma half-life of therapeutic proteins requests frequent administration, usually via parenteral routes. This short-coming is proposed to be solved by the development of an injectable microparticulate drug...

Suresh Kumar, P. (author)
Eutrophication and the resulting formation of harmful algal blooms causes huge economic and environmental damages. Phosphorus (P) has been identified as a major limiting nutrient for eutrophication. Phosphorous concentration greater than 100 µg P/L is usually considered high enough for causing eutrophication. The strictest regulations however...

Resources recovery from wastewater is pursued as it facilitates a circular economy, which a society runs with a minimal environmental impact. Eutectic freeze crystallisation (EFC) has been identified as a potential technology that can assist to achieve such goal. High quality of salt and ice can be retrieved with this treatment with a note of...

Wang, Yundan (author)
Water scarcity emphasizes the necessity of water recovery from saline sources, which are plentifully available. Nanofiltration (NF) is widely implemented in water reclamation treatment particularly in industrial field. However, the presence of silica hinders the possibility of obtaining a high recovery in a NF membrane system. In this work, the...

Wilfert, P.K. (author)
The scope of this thesis was to lay the basis for a phosphate recovery technology that can be applied on sewage sludge containing iron phosphate. Such a technology should come with minimal changes to the existing sludge treatment configuration while keeping the use of chemicals or energy as small as possible. The research focused on...

Waqué, Anna (author)
Brine that is produced during reverse osmosis (RO) could be further concentrated by another RO step. In the absence of bivalent cations, silica is a limiting factor because a high concentration of silica can cause irreversible fouling of the membranes. To prevent silica scale formation during the further concentration of brine with RO, silica...

GONZALEZ GONZALEZ, FELIPE (author)
Worldwide fresh water scarcity is nowadays becoming a reality rather than a futuristic concern. Non-conventional sources of wastewater are being considered as a solution for this problem, since fresh water sources will not be sufficient to satisfy the world’s water demand in the following years. Extensive research is being done on different...

Chen, Z. (author)
The drinking water distribution network is a sealed and pressurized system which attached numerous biofilm and microorganism due to the long-time operation. In a foreseeable future, Oasen will adopt reverse osmosis to treat drinking water and thus the nutrient (biodegradable compounds) in drinking water will be slight. In that case, biofilms...

Van Linden, N. (author)
In the application of the Zero Liquid Discharge (ZLD) strategy, not a single drop of water leaves the waste water treatment plant (WWTP). In the recovery strategy of an actual full-scale ZLD WWTP, the focus lies on high quality water, which is fully recovered from reverse osmosis brine (RO-brine). A residual solid stream is generated and...

The aim of this thesis is to determine if Natural Deep Eutectic Solvents (NADES) can be implemented in a commercially viable process. NADES are a new class of solvents which can be considered a bio-based version of Ionic liquids and Deep Eutectic Solvents. A case study is performed on the extracting of value added compounds from orange waste....

Lu, X. (author)
During the last decades, the consumption of raw materials and energy in the world has faced a tremendous increase with a corresponding industrial waste volume increases, which treatment poses serious challenges. From an economical point of view, the waste has values as it contains valuable matters. Disposal of these streams without any further...

Salvador Cob, S. (author)
Nanofiltration (NF) and reverse osmosis (RO) membranes are used to produce clean water, but also produce a concentrate stream which contains most of the contaminants. Discharging concentrate streams to the environment is hindered by regulations, which are becoming more strict, and by the desire of recovering every single valuable atom. Therefore...

Fabrics that are sensitive to water, may wrinkle or shrink when washed in regular washing machines and are usually cleaned by professional dry cleaners. Dry cleaning is a process of removing soils from substrate, in this case textile, using a non-aqueous solvent. The most common solvent in conventional dry cleaning is perchloroethylene (PER)....

Kazemi, S. (author)
Traditional chemical processes show shortcomings caused by using volatile organic compounds as solvents during reactions and separations. Therefore, it is necessary to address this issue by moving toward more environmentally friendly processes. This is possible by using less toxic and hazardous solvents, such as ionic liquids and supercritical...

Wagterveld, R.M. (author)
Scaling comprises the formation of hard mineral deposits on process or membrane equipment and calcium carbonate is the most common scaling salt. Especially in reverse osmosis (RO) membrane systems, scale formation has always been a serious limitation, causing flux decline, membrane degradation, loss of production and elevated operating costs. In...
