types of solid waste. To handle it well‚ we used to categorize and separate the type of waste. In waste water treatment‚ we simply separate the pollution as municipal waste (more polluted) and runoff(less polluted). But in solid waste‚ we define it as three types of waste that is more detail then water. They are Municipal Solid Waste (MSW)‚ Construction Waste and Special Waste. We defined these wastes by their properties. The figure shows that we have successfully reduce the total solid waste

in wetlands‚ which were thought to be wasteland back then. Early landfills leaked into rivers and lakes and built up gases‚ like methane. Garbage dumps used to catch fire and even explode‚ because as garbage rots‚ it gives off methane‚ a flammable gas. (Exploringnature.org‚ 2014) Early landfills have significant problems with the Leachate organization because it was an unconstrained contaminant release‚ the methane organization did not exist‚ and incomplete decomposition as well as settle was so

Gas Laws Gases exhibit many qualities that are very different from those of liquids or solids. Gases have particles that are farther apart when compared to liquids and solids. The particles in gases move at different speeds in random directions and they are constantly moving. These particles collide with each other and with whatever container or area they are in. Gases are also very easy to compress. They expand to fill their containers and they occupy far more space than the liquids and solids

Do all liquids evaporate? What would happen if liquids never evaporated? Do we know which liquid evaporates the fastest? Could we perhaps use this knowledge to change the everyday processes? The process of evaporation happens much differently than scientists once thought. Every liquid eventually evaporates and often what remains is the solid particles which were once part of the solution. Evaporation is very important: “it shapes the climate of the planet‚ it affects the cost of car travel

Lab 3 – Separation of a Mixture of Solids Cathy Lab Partners: Chelsea Brooke Sept 4‚ 2012 Chemistry 131A Dr. Vicki H Audia Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate. 1. Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The

FROZEN ROCK-SOLID At General Motors of Canada Ltd.‚ Nick Vanderstoop is in charge of implementing a system that he created to prevent the “erosion of knowledge”. He loves to scare the daylights out of GM executives and managers by telling them a true story about the company. The story goes something like this: Several years ago a worker at the head office of General Motors Canada Ltd. In Oshawa retired. Among the many tasks that were performed by him‚ one was particularly important. Every fall he

The study of shelf life for liquid biofertilizer from vegetable waste showed that contrary to the traditional advice that liquid biofertilizers produced from fermentation by effective microorganisms‚ should be used within three months of production‚ the liquid biofertilizer produced from vegetable waste still contains high amount of viable microbial population after four months of storage with no significant effect of the presence or absence of light (Ngampimol and Kunathigan‚ 2008).

Separation of a Mixture of Solids My Flow Chart First remove iron filings with magnet since this is the only substance in the mixture that it is magnetic and will be attracted to a magnet. Second remove the sand by adding the mixture to hot water‚ which the other two substances are soluble. Third remove the benzoic acid since this is less soluble in cold than salt by cooling the mixture in the heated water. This will then leave the table salt behind in the water as the last substance.
