SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement. Suspended solids refer

WASTE GENERATION ‘Waste’ is a very general word‚ used to include anything that is no longer needed for use and is thrown away uncared. It has created and added a new problem to the environmental pollution. Pollution also creates serious problems for human health. There is remarkable growth in energy generation‚ fertilizers‚ pesticides‚ chemicals‚ production of coal etc. All these and much more is expected to increase in the years to come. For this‚ we need to understand different sources of
