Tian, He (author)
Organic micropollutants (OMPs) originate from organic chemicals such as drugs and pesticides that are widely used in human activities. OMPs are difficult to remove by conventional water treatment techniques, and hence continue to accumulate in natural water bodies. More effective methods need to be investigated for the removal of OMPs in...

Large amounts of oily wastewater which included oil-in-water (O/W) emulsions, also known as produced water (PW), were produced in tandem with the enhanced oil recovery (EOR). Ultrafiltration (UF) was an effective and economic method to separate micron-sized O/W emulsions, while the membrane fouling limited its development. Understanding the...

With the development of industry, there is an increasing focus on environmental issues, while organic micro-pollutants (OMPs) have garnered significant attention as emerging contaminants in water. Due to the low concentration and small size, OMPs pose a challenge to retain in traditional low-pressure membrane filtration systems. Prior researches...

Aromatic compounds have always been of concern regarding their toxicity to living organisms, including microorganisms. With more anthropogenic activities (e.g. coal gasification), the need for feasible treatment of industrial effluents is highly prioritised. With the anaerobic degradation process being a competitive solution, these compounds’...

Membrane technology is widely used as an effective water treatment or pretreatment technology, especially in the filtration of oil-in-water (O/W) emulsions. Ceramic membranes have shown excellent performance in this regard. However, due to the complex composition of real wastewater, laboratory studies are limited to the filtration of simulated O...

Water scarcity is a serious issue on many smaller islands, with population growth and the predicted impacts of climate change as driving factors. Bonaire is a small island located in the Caribbean Sea that has rural areas without grid connections to electricity and water. Agriculture, both livestock and hobby crop farming, in the Punta Blanku...

Constant flux MF/UF filtration is preferred in real-world applications because it <br/>provides more consistent permeate flow rates than fixed transmembrane pressure studies. Particularly, little is understood about the fouling of ceramic membranes in constant flux filtration modes by nano-sized O/W emulsions. In this study, the effects of...

Ceramic ultrafiltration is a promising technology for water reclamation, but issues with membrane fouling and the removal of organic micro-pollutants have limited its development. Recent research has shown that catalysis-based ultrafiltration has the potential to address these problems. In this study, catalysis-modified (CuFe2O4 and Pd)...

Trials of surface modifications using low pressure chemical vapor deposition (LPCVD) has successfully decreased the high temperature needed for the fabrication of SiC membrane from 2000°C to below 900 °C. With this great success on the reduction of the energy con-sumption, however, further studies on the chemical stability and the fouling...

Water scarcity and uneven distribution of water resources pose a significant challenge globally. Searching for alternative water resources could alleviate this issue. Municipal sewage reclamation with ceramic NF membrane has gained momentum nowadays. However, the inevitable fouling, especially organic fouling during membrane filtration, is the...

In this study simultaneous and continuous inline dosing of PAC and coagulant in UF was investigated. Surface water was directly treated with PAC-UF and performance of the system was assessed by looking at membrane fouling and organic micropollutants removal. Combining adsorption and membrane processes in one technique, hybrid membrane processes,...

Ultrafiltration (UF) is an efficient and effective method of filtrating oil-in-water (O/W) emulsions. However, the favorable conditions of filtrating nano-sized O/W emulsions have not been investigated. This study investigated the influence of four different parameters including membrane pore size, cross flow velocity, pH and salinity on...

Natural organic matter is one of the key components to remove from source water during drinking water production. NOM not only negatively influences the colour, taste and smell of the water, it also decreases the effectiveness of common water treatment steps such as (membrane) filtration and UV desinfectation. A big fraction of natural organic...

This thesis constitutes a part of the "IMPRESS" project which is aiming at the production of bio-plastics by utilizing hemicellulosic hydrolysates. The hydrolysate stream, after following the steps of acid hydrolysis and neutralization, consists of monosaccharides (C5/C6 sugars), salt and sugar degradation products. The C5/C6 sugars need to be...

Zeolites can be used for the adsorption of organic micropollutants (OMPs) from water. In this research, the potential applications of zeolite granules for OMP removal in wastewater treatment plants (WWTPs) were discovered. The adsorption of 18 target OMPs by zeolite granules was fully studied in batch and column experiments. The adsorption...

In palm oil extraction process, a large amount of lipids are emulsified in waste stream and the hot, brownish palm oil mill effluent (POME) is generated. In this study, the membrane technology was proposed to test the feasibility of direct ultrafiltration (UF) of POME by using a-Al2O3 and PVDF membranes, and to figure out the recovery rates of...

Brine streams from industry is a burden to the environment if not disposed properly. “Zero liquid discharge” (ZLD) is an ideal way of converting saline streams from waste to resource through multiple membrane-based or thermal-based treatment technologies. The utilization of the recovered resource minimizes both costs and environmental impacts....
