	Contamination of Groundwater-Fed Springs in Uganda Royal Institute of Technology (KTH), Stockholm, Sweden Dr. Roger Thunvik and Robinah Kulabako of the Royal Institute of Technology in Stockholm use COMSOL Multiphysics to define just how the water contamination...
	Fine Tuning for Water Purification Amsterdam Water Supply (AWS), Amsterdam, Netherlands Amsterdam Water Supply AWS of the Netherlands produces some of the cleanest drinking water in the world, almost 100 million cubic meters per year in fact....
	COMSOL Reveals How to Avoid Very Expensive Modifications to Wastewater Clarifier Witteveen+Bos, Deventer, The Netherlands A group of consulting engineers used COMSOL Multiphysics® and the Mixture Model application mode at a wastewater treatment plant to determine that simply...

	Perforated Well Analysis of fluid flow into wells often begins with the assumption that the intake fluid is uniform along the entire length of wellbore. This assumption runs into trouble when applied to the modeling of perforated wells. When these wells...
	Reaction Chain This model describes the simultaneous transport of three solutes in a chain reaction within a variably saturated flow field. Involved are advection, dispersion, sorption, biodegradation, decay, and volatilization. The parent solute...
	Removing Contaminants in a Secondary Sedimentation Clarifier Wastewater treatment is a several-step process for removing contaminants. Firstly, large, solid particles are removed through sedimentation, flotation, and filtration. And then in a second step, biological treatment causes the smaller...
