Fouling and chemical stability study on SiC-Al2O3 ultrafiltration membrane for sodium alginate filtration under constant flux crossflow mode

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...

Fouling control in ceramic nanofiltration membrane by pre-coating with calcium carbonate

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...

The effect of surface charge on threshold flux and fouling behavior of silicon carbide membrane with O/W emulsion and sodium alginate solution as typical pollutants

Colloidal fouling has attracted increasing interest in the membrane field. Oil and water (O/W) emulsion droplet and Extracellular polymeric substance (EPS) are significant colloids in produced water and surface water, respectively. Oily wastewater is produced in many industrial processes such as oil and gas extraction processes, and can take a...

Towards a Circular Economy: Exploring the applications of 3D printing with mussel shell waste

Previous research proved the potential of using mussel shell waste as additive manufacturing (AM) material. In this thesis, mussel shell powder was combined with sodium alginate, since it allows reversible cross-linking. Due to reversible cross-linking, this water-soluble and recyclable material can temporarily be made water-resistant, so it can...

On the stability of cerium inhibiting layers on aluminium 2024-T3: an in situ optical and electrochemical study

Salts of trivalent cerium (Ce(III)) are known to successfully hinder localised corrosion phenomena typical of aerospace aluminium alloys by forming a thin passivation layer on top of the corrosion-active intermetallic phases. This is generally observed to happen when the alloy is under immersion conditions in a solution containing Ce3+ ions....

Improving Solid State Batteries Using Bio-derived Alginates

Advancements in energy storage technologies need to keep pace with the accelerating transition to renewable energy sources. Li metal anodes and high voltage cathode materials are widely considered to be the path into next generation Li-ion batteries, while the scare amounts of lithium in the earth's crust has prompted research into other battery...

Fouling Control in Ceramic Nanofiltration Membrane: Forward Flush and Precoating Method

The new concept of sewer mining which utilizes the ceramic nanofiltration (C-NF) membranes offers a compact solution for water and other resources recovery. However, since it has very limited pre-treatment process, membrane fouling is a common problem due to the direct contact between the membrane and sewage water. Sewage water contains a lot of...

Feasibility Study of Alginate Polymer Electrolytes through Molecular Dynamics Simulations

Large scale stationary energy storage is becoming the need of the hour as the world transitions to a renewable economy. For this, there is a necessity of higher energy density batteries that can cope well both in storing excess energy and minimizing fluctuations on the grid. Solid polymer electrolyte batteries can be extremely safe and reduce...

Developing Edible Barcodes from Hydrogels: A study on the influence of drying

Counterfeiting of food and pharmaceutical products, albeit a more serious issue in developing countries is, however, omnipresent. Therefore, there is an ever-growing need for anticounterfeiting measures to address this challenge. Currently, the existing overt and covert anticounterfeiting measures are more prevalent on the packaging of such...

Analysis of Alginate-like Exopolysaccharides for the Application in Enhanced Oil Recovery

Alginate-like exopolysaccharides (ALE) can be extracted from granular sludge, which is produced during aerobic granular sludge waste water treatment as a waste product. Processing the waste is a costly operation. It is believed that ALE consist mostly of alginates. The chemical and mechanical properties of alginates are potential for the...

Enhanced digestion and alginate-like-exopolysaccharides extraction from Nereda sludge

Aerobic granular sludge/Nereda technology has proven to be more beneficial compared to activated sludge systems. Until now not much research has been spend on treatment of Nereda excess sludge (NES). In this study the biodegradability of NES is investigated, combined with thermal pressure hydrolysis (TPH) as pre-treatment method and the...

Three dimensional model of a single cell in a alginate construct

In cell experiments there is an interest to acquire information how a cell responds to external loads. In gel studies these cells are imbedded in gel and the gel is deformed externally. Because the gel is deformed, the cells inside the gel will deform as well. In order to capture the deformation of the cell a confocal microscope is used. A...
