The critical factor in the creation and maintenance of dust-laden air or particle contaminated water is the nature of the particle, in terms of its size and its relative density. This is because of the development of a constant, terminal velocity by a particle falling freely through a fluid, whose value, as demonstrated by Stokes […]
Contaminants, i.e. minor impurities, are normally present in all fluids, natural or processed. Where the level of contamination in the fluid is significant, i.e. too great for that fluid to be consumed, or used for its proper purpose, or to be subsequently processed, then it becomes necessary (or in some cases legally obligatory) to remove […]
At the time of writing, there is much concern being expressed about the global environment and human influences upon it. Whether it is to do with climate change and its probable human cause; continued starvation in large regions of an otherwise rich world; or the conversion of a runaway consumption to a sustainable expansion, large […]
There is hardly a human activity, industrial, commercial or domestic, that is not affected by filtration. It is a very widely used process, from the kitchen counter top water filter to the enormous wastewater treatment plants, or from the delicate membrane ultrafilter to the rugged tipping pan filter of a mineral processing works. It has […]
The two major branches of physical separations technology, filtration and sedimentation, work by quite different mechanisms. Filtration operates entirely on particle or droplet size (and, to some extent, shape), such that particles below a certain size will pass through the barrier, while larger particles are retained on or in the barrier for later removal. The […]
From today on, Waterfiltech is gonna update the chapter and information on the practical filtration guide book named “Filters and Filtration Handbook”, written by Ken Surtherland, for a better understanding of filters and filtration spectrum. A book entitled Filters and Filtration Handbook is clearly stating its purpose in those words, but the primary topic – fluid […]

Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine substances from liquids or air. Filter paper comes in various porosities and grades depending on the applications it is meant for. The important parameters are wet strength, porosity, particle retention, flow rate, compatibility, efficiency […]
Selecting the correct filter paper in laboratory science is dependent upon the requirements involved in the use of the paper. These requirements will determine what type of particle retention and paper grade will be needed. Porosity and flow-rate are two factors that determine the particle retention of a paper. Particle retention is measured in relation […]
The market is literally flooded with water treatment options. Reverse osmosis systems, loose granular activated carbon, solid carbon block filters, and distillers all promise sparkling, clean water, but how do you know which one is really best? With a little research, you can find the ideal water treatment system for you. 1, Find out the […]
