In this water filtration lab, we’ll use simple household items like coffee filters and cotton balls to explore how filtration works. While it won’t make the water safe to drink, this project gives a clear visual representation of how the process works. Let’s get started and see how cle...
The filtration process is simple, but effective. The basic principle is that there are passages through the filter that are wide enough for water droplets to pass through, but too narrow for pathogens. Tests with the deadly E-coli bacterium have seen the filters remove 96.4 to 99.8 per cent...

This carbon–sulfur bond formation reaction is highly efficient and practical since it works under metal-free, neutral, aqueous media and at room temperature in which the products even can be obtained by simple filtration without the need for organic extraction or column chromatography. Water is ...
M.B. conceived the project and designed the experiments. M.D.V. fabricated the membranes, performed IR, EDX characterization and SEM analysis. L.-B.H. performed X-ray powder diffraction analysis. M.D.V. and A.T. designed and performed the filtration experiments. S.P.N. designed and V...
Say, it may be necessary to analyse the performance of a specific treatment system (UV disinfection, filtration, CO2, etc.) in relation to the possible failures of its components. The advantages of this analysis are that it provides a complete picture of the system and how the failure ...
After filtration, the water was collected by a 50-ml acid pre-cleaned high density polythene (HDPE) bottle, and strong guaranteed nitric acid was added into the water sample until the pH of the water was below 2 for cation measurement. All the water samples were preserved in the cold room...
In any case KCl can be effective to inhibit clay swelling, however, the presence of large quantities of KCl (from 2% to 7% by weight) in the drilling fluids can adversely affect rheology, filtration control and biological ecosystems (Akhtamanesh et al., 2013; Zhong et al., 2011). A ...
