Kramer, F. C. (author), Shang, R. (author), Rietveld, L.C. (author), Heijman, Sebastiaan (author)Ceramic nanofiltration is an emerging technology for the recovery of water and nutrients (including phosphate) from municipal sewage which becomes more imperative worldwide. In order to use ceramic nanofiltration for phosphate recovery from municipal sewage, more knowledge is needed. This is the first paper reporting the phosphate retention of...journal article 2019

Kramer, O.J.I. (author)Van een afstand in de ruimte ziet onze aarde er blauw uit. Je zou het daarom misschien niet verwachten, maar onze mooie planeet is toch heel erg droog. Met een toenemende wereldbevolking en een wens naar meer welvaart neemt de ‘water-stress’ steeds meer toe en dit betreft vooral zoet en schoon water.<br/><br/>Het milieu wordt zwaarder belast met...other 2018

Kramer, O.J.I. (author)One of the most popular and frequently used models for describing homogeneous liquid-solid fluidised suspensions is the model developed by Richardson & Zaki in 1954. The superficial fluid velocity and terminal settling velocity together with an index, make it possible to determine the fluid porosity in a straightforward way. To maintain...other 2018

Avdis, A. (author), Candy, A.S. (author), Hill, J. (author), Kramer, SC (author), Piggott, M.D. (author)Renewable energy is the cornerstone of preventing dangerous climate change whilst main- taining a robust energy supply. Tidal energy will arguably play a critical role in the renewable energy portfolio as it is both predictable and reliable, and can be put in place across the globe. However, installation may impact the local and regional ecology...journal article 2018

(author)Background: Pharmacokinetic (PK) models can describe microvascular density and integrity. An essential component of PK models is the arterial input function (AIF) representing the time-dependent concentration of contrast agent (CA) in the blood plasma supplied to a tissue.

(author)Various mechanisms have been proposed to explain the nonphotochemical laser-induced nucleation (NPLIN). Identifying the dominant mechanism requires addressing a large set of experimental parameters with a statistically significant number of samples, forced by the stochastic nature of nucleation. In this study, with aqueous KCl system, we...journal article 2018

Shen, Y. (author), Lindenbergh, R.C. (author), Hofland, Bas (author), Kramer, R. (author)For better understanding how coastal structures with gentle slopes behave during high energy events, a wave attack experiment representing a storm of 3000 waves was performed in a flume facility. Two setups with different steepness of slope were compared under the same conditions. In order to quantify changes in the rock slopes after the wave...conference paper 2017

Kramer, O.J.I. (author), de Moel, P.J. (author), Baars, E.T. (author), van Vugt, W.H. (author), van der Hoek, J.P. (author)Natural particles are frequently applied in drinking water treatment in up-flow fluidisation processes. Additionally, sedimentation processes are applied to clarify water and to concentrate solids. To estimate the terminal settling velocity of single solid particles in a liquid system, a comprehensive collection of equations is available. For...conference paper 2017

Inflexible (predetermined) control strategies fail to grow the nucleated crystals to the desired quality because of the variability in the process conditions, disturbances, and the stochastic nature of...journal article 2017
