Contact the supplierThe intended result of chemical disinfection of drinking water is reduction of microbial contamination and a concomitant decrease in waterborne disease. The formation of a myriad of disinfection by-products (DBPs) is an unintended consequence. DBPs are present in water as highly complex mixtures. To date, more than 600 unique DBPs have been identified; despite this massive identification ...

There are five steps to basic water purification: aeration, coagulation, sedimentation, filtration, and disinfection. Our project took us through the first four. Aeration adds air to the water. It allows gases trapped in the water to escape and adds oxygen to the water.

Contact the supplierBacteriophage MS2 was more UV resistant than any of these viruses tested. Additionally, UV disinfection experiments were carried out using cell-associated echovirus 12. Compared to monodispersed echovirus 12, the cell associated virus required two to three times greater UV dose for a given level of log reduction.

Contact the supplierQ: What is the science behind tie-dye? A: The dyes are called fiber-reactive. That means a chemical reaction takes place between the dye molecules and the fabric molecules. The dye bonds with the cotton and actually becomes a part of the fabric. That is why the dyes are so permanent and vibrant even after several washings. Science Fair Connection

Contact the supplierKnowledge about the sensitivity of the test organism is essential for the evaluation of any disinfection method. In this work we show that sensitivity of Escherichia coli MG1655 to three physical stresses (mild heat, UVA light, and sunlight) that are relevant in the disinfection of drinking water with solar radiation is determined by the specific growth rate of the culture.

Contact the supplierFeb 20, 2019·There are numerous exciting science projects that you can try where you'll make things glow in the dark using a black light or ultraviolet lamp. Here are some fun glowing projects to try. Most of these projects glow due to fluorescence, though some projects involve phosphorescent materials that glow on their own, but much more brightly when exposed to a black light.
Contact the supplierA kit for this project is available from our partner Home Science Tools. Cost: High ($100 - $150) Safety: Wear gloves when conducting the experiment. Read and follow the instructions in the Microorganisms Safety Guide. Do not drink any of the water that results from the SODIS process. See the Experimental Procedure for more information.
Contact the supplierEfforts to control of unwanted disinfection by-products (DBPs) can be hindered by the relatively low-frequency data that is generated from DBP monitoring for regulatory purposes. Differential UV absorbance (DUVA) has the potential to overcome some of these difficulties as a relatively simple and low-cost technique for the estimation of regulated DBPs (i.e., trihalomethanes, THMs, and ...
