Magnetic separation is a very old separation technology, which is mainly used, in the mineral industry. In these applications, the magnetic force is applied to separate magnetic from non-magnetic materials. The separation efficiency strongly depends on the magnetic properties of the materials as well as the particle sizes. This paper introduces a totally new magnetic separation process, which c...

Filtration mechanisms are known for only two species of suspension-feeding tilapia, each of which relies on a different method of particle retention. We used high-speed video endoscopy to assess whether a third species of tilapia, Oreochromis aureus, with gill rakers intact as well as surgically removed, uses mucus in the oropharyngeal cavity for hydrosol filtration or uses crossflow filtration...

Many contaminants of interest in water and wastewater are particles, or are made into particles for removal. Typical municipal wastewater treatment plants include both primary and secondary sedimentation, and those with tertiary treatment likely have granular media filtration. Typical drinking water plants using surface water supplies have flocculation, gravity separation (sedimentation or flot...

The transfer of water from a swimming pool to the treatment location is key in determining effectiveness by filtration removing turbidity and managing risk particulate material, including microbial pathogens, such as Cryptosporidium spp. A recommendation for operators when dealing with an accidental faecal release (the likely main source high oocyst concentrations pools) that should be filtered...

(2009), Constraints on the utility of MnO 2 cartridge method for the extraction of radionuclides: A case study using 234 Th, Geochem. [1] Large volume (10 2 –10 3 L) seawater samples are routinely processed to investigate the partitioning of particle reactive radionuclides and Ra between solution and size-fractionated suspended particulate matter. One of the most frequently used methods to prec...
