Engineering For Safe Chlorine Disinfection By Harland R. Pond, Product Manager, Grundfos
For more than 75 years, chlorine has been effectively used to disinfect drinking water, eliminating dangerous bacteria and toxic compounds. Water supply engineers and treatment facility operators are used to necessary risks and problems associated with chlorine disinfection in order to deliver safe water.
Solving Complexities In Overland Flow Patterns In An Urbanized Catchment By XP Solutions
The 1D/2D modeling approach was applied on the Glen Eira basin in Victoria, Australia, to produce flood maps of 10-year and 100-year rainfall events. The study ensures that the integrated modeling approach is the best option for a realistic and authentic reproduction of urban flood extents.
Biological Filtration For Iron And Manganese Removal By Pierre Mouchet, Degremont Technologies
Physical and chemical processes conventionally used to remove iron and manganese from groundwater (aeration plus filtration) led to the discovery of coincident biological phenomena. These were subsequently applied to enhance the performance of certain existing units and, especially, to serve as a basis for a new generation of biological treatment plants. This article illustrates a number of examples, selected from among nearly 200 existing facilities.
Atlas Copco ZS+ VSD blowers balance the two key prerequisites when choosing a blower: reliability and energy efficiency. Integrating the proven benefits of screw technology, the ZS+ VSD reduces energy costs by an average of 30 percent when compared to lobe technology.
