Synergy of phosphate recovery from sludge-incinerated ash and coagulant production by desalinated brine

Wang, Xiangyang (author), Shi, Chen (author), Hao, Xiaodi (author), van Loosdrecht, Mark C.M. (author), Wu, Yuanyuan (author)

Wet-chemical approach is widely applied for phosphate recovery from incinerated ash of waste activated sludge (WAS), along with metals removed/recovered. The high contents of both aluminum (Al) and iron (Fe) in WAS-incinerated ash should be suitable for producing coagulants with some waste anions like Cl⁻ and SO₄<sup>2−<...

The influence of preparation and pretreatment on the physicochemical properties and performance of plant-based biocoagulants in treating wastewater

Kurniawan, Setyo Budi (author), Ahmad, Azmi (author), Said, Nor Sakinah Mohd (author), Gustinasari, Kiki (author), Abdullah, Siti Rozaimah Sheikh (author), Imron, M.F. (author)

Biocoagulants have gained attention as an alternative to chemical coagulants in water and wastewater treatment due to their ability to remove pollutant parameters such as turbidity, suspended solids, color, and organic compounds. Plant-based biocoagulants are currently the most promising due to their abundant availability and reliable...

Enhancing performance of ultrafiltration with inline dosing of coagulant and powdered activated carbon: Effect on fouling and removal of organic micropollutants including poly- and perfluoroalkyl substances

Vis, Anna (author)

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,...

Removal of Antibiotic Resistance From Municipal Secondary Effluents by Ozone-Activated Carbon Filtration

Spit, T.P.M. (author), van der Hoek, J.P. (author), de Jong, Coen (author), van Halem, D. (author), de Kreuk, M.K. (author), Bicudo, Bruno (author)

At wastewater treatment plants (WWTPs), additional steps are introduced for removal of organic micropollutants (OMPs) from the treated effluents, especially pharmaceutical residues. At the same time, a new concern is emerging: antibiotic resistance (AR). This research studied the effect of ozonation, coagulation and granular activated carbon ...

Creating coagulants through the combined use of ash and brine

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...

Phosphonate removal from membrane concentrate by electro-coagulation

Torres Serrano, V.M. (author), Eshun, Lordina Ekua (author), Farinha, Andreia (author), Witkamp, Geert Jan (author), Bucs, Szilard (author)

In this study, the efficiency of electrocoagulation (EC) with iron electrodes was applied to remove two phosphonates, 1-hydroxyethylidene-1, 1-diphosphonic acid (HEDP) and nitrilotris(methylene) triphosphonic acid (NTMP) from concentrates. This work provides a detailed description of the experimental procedure and results on phosphonate...

Formation of planets via pebble accretion

Liu, Jordi (author)

Within a Protoplanetary disk (PPD), planets form from micron sized particles, but what are the processes taken for planet formation? How does the evolution of micron sized particles via settlement and coagulation lead to the gigantic planets as the ones in our Solar System? This thesis explores the planet formation process of pebble accretion...

Impact of adding aluminum hydroxyl chloride on membrane flux in an anaerobic membrane bioreactor

Yang, Jixiang (author), Spanjers, H. (author), van Lier, J.B. (author)

Coagulant addition and improved mixing conditions have been used in anaerobic membrane bioreactors (AnMBR) to improve membrane performance. Before coagulant was added, a flux of 8 L/m² h was applicable and transmembrane pressure (TMP) increased from 1 kPa to 10 kPa in 5 days. However, after the coagulant was added, a flux as high...

Geotextile tubes filled with mine tailings as a construction element

Bosman, Pieter (author)

Large quantities of mine tailings are stored in mine tailings storage facilities. These facilities are only costing money for mining companies. In addition, these tailings storage facilities are prone to failure. To prevent this from happening these facilities have to be reinforced. This research introduces a concept to use geotextile tubes...

Real-time oncological guidance using diffuse reflectance spectroscopy in electrosurgery: The effect of coagulation on tissue discrimination

Adank, Maartje W. (author), Fleischer, J.C. (author), Dankelman, J. (author), Hendriks, B.H.W. (author)

In breast surgery, a lack of knowledge about what is below the tissue surface may lead to positive tumor margins and iatrogenic damage. Diffuse reflectance spectroscopy (DRS) is a spectroscopic technique that can distinguish between healthy and tumor tissue making it a suitable technology for intraoperative guidance. However, because tumor...
