One-year operational experience with ultrafiltration as pretreatment of seawater reverse osmosis desalination system (Maspalomas-I Plant).
TLDR
In this article, the design and operational aspects of the country's largest integrated hollow fiber ultrafiltration and reverse osmosis (RO) system to treat seawater in a remote island were discussed.Abstract:
The selection of a proper pretreatment for reverse osmosis (RO) systems is essential to produce a high-quality feed water in order to ensure a more sustainable and reliable operation. Traditionally, seawater RO installations have been operated with conventional pretreatments based on single- or two-staged media filtration, and occasionally preceded by coagulation/flocculation processes. In recent years, however, hollow fiber ultrafiltration (UF) technology has increasingly gained acceptance as a viable pretreatment alternative for seawater desalination, due to advantages such as greater capability to cope with fluctuations and high solid loads in raw waters (typical of open intakes), smaller footprint, higher and more consistent filtrate water quality, and higher environmental sustainability, ultimately demonstrating lower total water cost in the long-term operation. In this article, design and operational aspects of the country’s largest integrated UF and RO system to treat seawater in a remote i...read more

Osmotically assisted reverse osmosis (OARO): Five approaches to dewatering saline brines using pressure-driven membrane processes
TL;DR: In this article, five different OARO integrated flow processes are modelled numerically to determine their technical and economical feasibility in maximising the process recovery, and three of them are novel, and offer technical and economic advantages over the previously proposed oARO processes.

Retention of natural organic matter by ultrafiltration and the mitigation of membrane fouling through pre-treatment, membrane enhancement, and cleaning - A review
TL;DR: In this paper, the main mitigation routes that are reviewed are UF pre-treatment, in-situ physical and/or chemical cleaning, and membrane enhancement, while several membrane enhancement solutions are promising, the scalability and economic feasibility of these modifications remain questionable.

Experience with integrated ultrafiltration/reverse osmosis systems in industrial applications in Spain
TL;DR: In this paper, the authors proposed that membrane fouling remains one of the main causes for poor RO plant performance, which implies frequent downtime for cleaning and maintenance and shorter membrane life time, leading to significant operational costs.
