Operations used for the treatment of wastewater in which change is brought about by means of or through the application of physical forces are known as physical unit operations. Because physical unit operations were derived originally from observations of the physical world. they were the first treatment methods to be used. Today, physical unit operations, as shown on Fig. 5-1, are a major part of most wastewater

Every community produces both liquid and solid wastes and air emissions. The liquid waste-wastewater is essentially the water supply of the community after it has been used in a variety of applications. From the standpoint of sources of generation, wastewater may be defined as a combination of the liquid or water-carried wastes removed from residences. institutions and commercial and industrial establishments together with such groundwater

1 Stationarity and unit Root testing WHy do we need to test for Non-Stationarity? The stationarity or otherwise of a series can strongly influence its behaviour and properties -e.g. persistence of shocks will be infinite for nonstationary series Spurious regressions. If two variables are trending over

CCCma has develped a number of climate simulation models for climate prediction, study of climate change and variability, and to better understand the various processes which govern our climate system. A brief description of these models and their corresponding references can be found in this section
