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...

The literature provides a comprehensive collection of equations to estimate the<br/>terminal settling velocity of single solid particles in a liquid system. The settling velocity for perfectly round spheres can accurately be calculated. In the contrary for natural imperfect particles the experimentally measured settling velocity deviates...

About 50% of the drinking water in the Netherlands is centrally softened by the drinking water companies in a process known as pellet softening. In this process a base and seeding material are mixed in an upflow reactor, where subsequently CaCO3 precipitates on a seed core as pellets. The seeding material is usually sand, but recently CaCO3 was...

Fiber reinforced cementitious composite (FRCC) has a great capability for selfhealing of cracks. Concrete cracks with a sufficiently small crack width (below 0.1 mm) can be closed and self-healed by crystallization of calcium carbonate in the presence of moisture, even in the case of ordinary concrete. Such precipitation is caused by reaction of...
