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’...

On the 14th of July 2013, a methane peak was observed in the Gale crater. This methane peak has been investigated in a non-biological context before. This study applies exoplanet research strategies and knowledge about biological methane production on Earth to investigate the biological context. Bayes formula is the foundation of the Bayesian...

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...

Excess nitrogen disposal into the environment increased with the discovery of an artificial way of nitrogen gas conversion to ammonia, and its implementation to industrial scale. The excess wasted fixed nitrogen ended up in rivers, lakes, oceans which resulted in degrading air, water and soil due to exceedance of the amount of nitrogen that can...

An increasing trend of urbanization, land shortages and frequent floodings have created unfavorable living circumstances for Philippine inhabitants. Finch Floating Homes aims to repurpose the permanently flooded ricefields in Hagonoy into flood-proof, typhoon-resilient, affordable housing. The floating neighborhood will serve as storm-resilient...

Fine sieved fraction (FSF) is a solid waste generated from wastewater treatment plants (WWTPs). Cellulose fiber is the most important component of FSF, which can be fermented into volatile fatty acids (VFAs) and then be used as carbon sources in biological nutrient removal (BNR). This thesis measured and evaluated the aerobic & anaerobic...

Palm oil is a popular ingredient in domestic products. The palm oil industry has been growing rapidly over the past decades, so that the amount of palm oil mill effluent (POME) generated from the palm oil production has been increasing as well. The anaerobic membrane bioreactor (AnMBR) is a treatment solution that can remove organic pollutants...

The hydrolysis of sludge solids especially for difficultly degradable sludges such as WAS is not fully understood, yet. The first-order hydrolysis rate was shown to function well for most easily degradable sludges and soluble substrates. This description for substrate hydrolysis in the context of anaerobic digestion has the benefit of being very...

There are more than 160,000 recreational crafts in the Netherlands with a toilet on board. It is forbidden to discharge blackwater into the environment from these crafts. Stricter enforcement of the law by the sealing of the valves of the external drain, leaves the owners of these crafts with a major problem. It is allowed, however, to treat the...

Palm Oil Mill Effluent (POME) is an attractive medium for biogas production in an anaerobic membrane bioreactor (AnMBR) because of its high lipid content. Long-chain fatty acid (LCFA) accumulation is toxic and considered harmful for the biological performance within the reactor as they can be absorbed by biomass particles causing sludge...

The presence of high levels of arsenic in groundwater, an otherwise preferred drinking water source, urges the need for innovative and highly efficient (in terms of chemical use and energy consumption) technologies to remove arsenic during drinking water treatment. This research focussed on embedding iron electrocoagulation (Fe-EC) within a...

The abundant presence of nitrogen in natural waters can be a threat to both humans and environment. Therefore, municipal and industrial wastewater streams need to be treated before their disposal in the environment. Currently used biological and physical-chemical treatment methods have drawbacks such as high greenhouse gas emissions, high energy...

Palm oil mill effluent (POME) is a high organic pollution produced during the palm oil mill process, with a brownish color and stingy odor at high temperatures. Given the popularity in palm oil output over the years, the massive amount of POME causes growing concern. The enforcement of wastewater discharge standards and laws, as well as energy...

Fouling is the main limitation to the application of membrane bioreactors (MBRs). Understanding the complexity of fouling has led to better decision making for design and operation of MBRs. However, studies have shown contradictory results of the impact of sludge characteristics on membrane filtration performance and fouling propensity. The...

Wastewater discharged from the domestic household has proven to be a potential source for resource recovery. Apart from wastewater, kitchen organic waste contains an enormous amount of energy in terms of organic content and nutrients such as TKN and TPH. Now that the disposal of waste into landfills is prohibited in most parts of Europe, one of...

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...

This study investigates the many dynamics of the Manyame Catchment and comes up with recommendations on how to adapt or become more resilient to the risks at hand. The bad politics and forthcoming economic situation of Zimbabwe has led to instability and dramatic inflation over the last decade. This has resulted in a terrible investment climate,...

In the context of steering product formation in anaerobic digestion systems, the present thesis work elaborates on the potential role of elevated CO2 partial pressures as an environmental driver that may influence end-product selectivity from methane towards compounds from the carboxylic platform. As an emerging field of research, organic acid...

Water as a coolant for industrial products or processes is widely used. Efficient operation of Open Recirculating Cooling Water Systems (ORCWS) relies on controlled cooling water conditioning programs that prevent corrosion, fouling, scaling and microbial growth. Water intensive industries feel greater pressure to decrease their water demand as...
