Unfortunately today, more than a billion people lack access to safe drinking water. Consider these: • Thirty percent of the world does not have enough water to drink or wash with. • More than two million children are dying every year from water related problems with increasing cases of cholera, dysentery and typhoid. • Seven billion people in…

Radon is a colorless chemically-unreactive inert gas. You cannot see it, smell it or taste it. The atomic radius is 1.34 angstroms and it is the heaviest known gas. Radon is nine times denser than air. Because it is a single atom gas it easily penetrates many common materials like paper, low density plastic, most paints, and building materials like gypsum board, concrete block, wood paneling, and most insulations. Radon was discovered by Ernest Rutherford and Robert B. Owens in 1899.…

(d) VOC abatement: For VOCs abatement we have adsorption systems like: Bio filters, Activated carbon, Flares, Thermal oxidizers, Catalytic converters, Absorption (scrubbing), Vapor recovery systems, Cryogenic condensers.(C.C.Tawari, et,al, 2012). 4.1.4 Other Devices. Acid Gas and SO2 control: This…

water resulting in the loss of some organic compound during filtration. Another reason for such a low percent recovery could be due to the drying agent. If the drying agent is added in large amounts it could lead to losing of the organic solvent by adsorption of the organic liquid. A better experimental result would show much higher percent recovery than the ones obtained. Obtaining a 100% recovery means that nothing was lost in the process. Also, the compound could have been impure and/or…

the papillomaviridae spikes will be housed only in skin and mucosal cells (WHO). This DNA virus doesn’t contain an envelope like the others it has less protection (WHO). Due to this difference of structure the way of entry the cell will occur is adsorption, which result in only the plasmid (DNA) will be allowed within the cell (POWERPOINT). Papillomaviridae is a virus (not living) which means that…

In microorganisms metal resistance character is regulated by genes which are organized in operons. Commonly, the heavy metal resistance genes are found on plasmid carried by metal resistant bacteria. In the presence of specific metals in the vicinity of bacterial niche the heavy metal resistance genes are expressed and induced. The regulation of expression of metal resistant gene is specific for each heavy metal and is dependent upon metal species concentration. The promoter and regulator genes…

For gravity type filtration systems, the filter medium can be mechanically or chemically driven to remove contaminates. The most common methods of contaminate removal for filtration medium mechanically remove large particulates, adsorption, absorption and redox or chemical reactions to produce safe drinking water2. Porous filter medium allows more medium surface area to interact with contaminates in the water as well as to create smaller pathways to mechanically remove particulates…

Can the refrigerator be considered as an artificial cold that a person cannot live without? Many different authors have their own styles of writing and their own know how’s as to when to use the “s” to possess. Steven Johnson, a British-American, had published a book called, “How We Got to Now.” In the book, he presented a six-part series where it had amazing explored legacies that passed on great ideas. In each of the chapters’ titles, the six sessions are: Glass, Cold, Sound, Clean, Time, and…

Many of us would like to understand what Arsenic is and why this element is in our drinking water. To begin with our introduction to Arsenic, we should all understand that it is a semi-metal element from the periodic table that we are mostly familiar with. It is odorless and has no type of specific taste to the human tongue. It is mostly sourced from natural deposits in the Earth, however, it’s also known to be sourced from agricultural and industrial practices all over the world. It is simply…

Chromatography Abstract: The purpose of this lab is to use chromatography to separate and purify organic compounds. There are many different types of chromatography but most depend on the principle of adsorption. The two important components of chromatography are the adsorbent and the eluent. Adsorbents are usually solid materials that will attract and adsorb the materials to be separated. The eluent is the solvent, which carries the materials to be separated through the adsorbent. After being…
