Water Treatment Methods

Water Treatment Methods

•     Flocculation/Sedimentation Flocculation refers to water treatment processes that combine small particles into larger particles, which settle out of the water as sediment.
•         Filtration
•         Ion Exchange Ion exchange can be used to treat hard water. It can also be used to remove arsenic, chromium, excess fluoride, nitrates, radium, and uranium.
•         Adsorption Organic contaminants, color, and taste- and odor-causing compounds can stick to the surface of granular or powdered activated carbon (GAC or PAC). GAC is generally more effective than PAC in removing these contaminants. Adsorption is not commonly used in public water supplies.
•      Disinfection (chlorination, ozonation) Water is often disinfected before it enters the distribution system to ensure that dangerous microbes are killed. Chlorine, chloramines, chlorine dioxide, ozone

Geometrical standards for Runways (Transportation Engineering)

Geometric standards for runways Geometric standards for various runways elements are as follow; 1.   length 2.   width 3.   longitudinal gradient & profile 4.   transverse gradient 5.   runway intersections 1) length Selection of length of a runway is the most important decision in the planning of landing area. Runway lengths for various types of airports recommended by ICAO are for sea level elevation, standard atmospheric conditions; ·         59 0 F or 15 0 C ·         29.92”barometer pressure ·         zero effective gradient ·         No wind The basic lengths recommended by FAA are based on the same conditions except that temperature of 100 0 F (41 0 C above standard) has been included in the length. Necessary corrections have to be applied for changes in elevation, temperature a...

To measure the pH of different samples in the laboratory.

Ø Experiment 1                                    To measure the pH of different samples in the laboratory. Ø Theory                                 The pH scale is a measure of the hydrogen ion concentration. The pH scale ranges from 0 to 14. pH symbol rooted in the French " p ouvoir h ydrogene " (power of hydrogen).It measures the acidity or basicity of a solution. A pH of 7 means it is a neutral solution. Pure water has a pH of 7. A pH of less than 7 means the solution is acidic. A pH of more than 7 means the solution is basic. The less pH, the more acidic the solution is. The more pH, the more basic the solution is. pH stands for the power of H, or the amount of...
