Yuvaraj, Ananya (author)Lignocellulose is an abundant source of feedstock and consists of hemicellulose, cellulose, and lignin. Pre-treatment is done to fragment lignin and hydrolyse the hemicellulose and cellulose fractions into simple sugars which is then converted into bioplastics. The pre-treatment generates a mix of sugar solutions, lignin breakdown products and...master thesis 2023

Huisman, Kees Theo (author), Franco-Clavijo, Natalia (author), Vrouwenvelder, J.S. (author), Blankert, Bastiaan (author)In this study, a biofouling index based on the relative pressure drop is presented to quantitatively evaluate the amount of fouling in spacer-filled membrane filtration channels. The biofouling index was defined as the inverse of the time to reach a relative pressure drop of 100% and can be interpreted as a fouling rate or cleaning frequency....journal article 2023

LI, CHANGLIN (author)The brine generated from desalination is a threat to the environment, and its disposal has been a great challenge. A new concept Zero liquid discharge (ZLD) can minimize the environmental impact of brine. However, the high costs for construction and running of a ZLD plant limits its growth in desalination market. Therefore, a new strategy...student report 2022

(author), Necibi, Mohamed Chaker (author), Chehbouni, Abdelghani (author)Many desalination plants still struggle to control biological fouling in seawater reverse osmosis (SWRO) systems as there are no standard methods to monitor this type of fouling. Strategies to control biofouling in SWRO systems have been proposed such as antifouling coating and lowering biofouling potential in SWRO feedwater through...review 2022

Hao, Xiaodi (author), Wang, Xiangyang (author), Shi, Chen (author), van Loosdrecht, Mark C.M. (author), Wu, Yuanyuan (author)Sludge incineration and seawater desalination are two approaches that can be used in the disposal of waste activated sludge (WAS) and for obtaining fresh water. As resource recovery from wastewater treatment and water purification is a topic of particular interest in these times, “water mining” has become a focus of research, with phosphate/P...journal article 2022

Bdour, Ahmed N. (author), Al-Sadeq, Noor (author), Gharaibeh, Muna (author), Mendoza-Sammet, Angeles (author), Kennedy, M.D. (author), Salinas-Rodriguez, Sergio G. (author)Jordan was late in adopting seawater and brackish water desalination as a source until the late 1990s and early 2000s. However, ongoing studies are still discussing the technical, economic, and socio-political aspects of brackish water reverse osmosis (BWRO) desalination plants. In this study, the water–energy nexus was considered, in order...journal article 2022

van Hanswijk, Daniel (author)Growth of the population, industry and agriculture increases the demand for fresh water. However, with only a small portion of the water on earth being suitable for direct human use and consumption, this growth makes water scarcity an increasing problem. Seawater desalination is an effective method to counter such water stress. Reverse Osmosis ...master thesis 2021

Javier, Luisa (author), Pulido-Beltran, Laura (author), Kruithof, Joop (author), Vrouwenvelder, J.S. (author), Farhat, Nadia M. (author)Biofouling is a problem that hinders sustainable membrane-based desalination and the stratification of bacterial populations over the biofilm’s height is suggested to compromise the efficiency of cleaning strategies. Some studies reported a base biofilm layer attached to the membrane that is harder to remove. Previous research suggested...journal article 2021

Javier, Luisa (author), Farhat, Nadia M. (author), Vrouwenvelder, J.S. (author)A critical problem in seawater reverse osmosis (RO) filtration processes is biofilm accumulation, which reduces system performance and increases energy requirements. As a result, membrane systems need to be periodically cleaned by combining chemical and physical protocols. Nutrient limitation in the feed water is a strategy to control biofilm...journal article 2021
