Environmental Chemistry Total views (497)  
For many glass the attention of environmental science arid engineering was devoted largely to the development of safe water supply and sanitary disposal of human wastes. Because of the success in controlling the spread of enteric diseases through the application of engineering principles, a new concept of the potentialities of preventive medicine was born.

Reaction Kinetics, Electrochemistry and its Applications Total views (496)  
From the stand point of process selection and design, the controlling stoichiometry and the rate of the reaction of principal concern. The number of moles of a substance entering into a reaction and the number of moles of the, substances produced are defined by the stoichiometry of a reaction.

Physical and Equilibrium Chemistry Total views (417)  
A knowledge of equilibrium chemistry has become increasingly important for detennining quantitative relationship between the various constituents in natural & contaminated waters and for understanding the effect of in the water on the various chemical spices present. This matter is important because of the one of the physical- chemical methods for treating waste waters & sanitary -land fill leacha ......

Applications of Colloids in Environmental Management Total views (421)  
In water and wastewater the filterable-solids fraction consists of colloidal and dissolved solids. The collided fraction consists of particulate matter with an approximate size range of from 0.001 to 1 pm. The dissolved solids consists of both organic and inorganic molecules and ions that are present in true solution in water.

Colourimetry and its Applications Total views (420)  
The correlation between physics and physiology when it comes to colour perception was recognised very early on. While physicist Sir Isaac Newton had already made a key contribution to spectrophotometry and colourimetry in 1704 with his attempts to split white light into spectral colours, the effect on the human eye was actually defined 100 years later by the physician Thomas Young.

Water Resources and Estimation of Pollutional Parameters Total views (419)  
Surface water is obviously highly susceptible to contamination. It has historically been the most convenient sewer for industry and town municipalities alike, while at the sometime it is the source of majority of our water for all purposes. One particular category of pollutants, oxygen demanding wastes, has been such a pervasive surface water problem, affecting both moving water and still water, t ......

Environmental Significance of Pollutional Parameters Total views (415)  
Water that has been withdrawn, used for various beneficial purpose and after usage the returned water will be polluted in one way or the other. Agricultural return water contains pesticides, fertilizer and salts; municipal return water carries human swage; power plants discharge water at elevated temperature; industry contributes a wide range of chemical pollutants may be either organic or inorgan ......

Sanitary Significance of Nutrients Total views (418)  
The phosphate determination has grown rapidly in importance in environmental science and engineering practices as scientist engineers have realized the many ways in which phosphorous compounds affect the phenomena with which they are concerned. The only inorganic compounds of phosphorus of significance in engineering practice are the phosphates or their molecularly dehydrated forms, usually referr ......

Membrane Filtration in Water and Wastewater Treatment Total views (424)  
Membrane filtration include a broad range of separation processes from filtration and 1lltrafiltartion to reverse osmosis. Generally, those processes defined as filtration refer to systems in which discrete holes or pores exist in the filter media, generally in the order of 102 to l04nm or larger. The efficiency of this type of filtration depends entirely on the difference in size between the pore ......

Optical Methods Total views (423)  
Optical method of analysis involves the measurement of light intensity. To relate optical measurement to the amount of a particular substance in a sample, it is necessary to exploit the ability of atoms or molecules to absorb or emit light radiation when exposed to a particular set of conditions. Thus this method of analysis involves the use of instrument with degrees of sophistication.

Electrical Methods Total views (427)  
Potentiometric measurement provide a highly selective method for quantitative determination of numerous cations and anions. During a chemical reaction, there is a change in the concentration of an ion which can be sensed through the change in potential of a suitable electrode, and then the progress of the reaction can be followed through this potential change.

Chromatographic Methods Total views (428)  
The concept of chromatographic separation has a long history. Thus, Aristotle's contemporaries used various types of sorbents (earths) to process seawater. More "scientific" applications were developed much later, by Runge in 1850,chonbein in 1861, Goppelsroder in 1861 and Day in 1900, and also by Kvita, Albrecht and Engler in the same period.

Other Instrumental Methods Total views (429)  
AAS will be used for determining both qualitative as well as quantitative aspects of environmental pollutants. Flame photometry is used in water analysis for determing the concentration of alkali and alkaline earth metal such sodium, potassium and calciums. Ion meter is used to determine the fluoride and nitrate concentration present in water.
