Sedimentation and Clarification Sedimentation Is the Next Step in Conventional Filtration Plants
Sedimentation and Clarification Sedimentation is the next step in conventional filtration plants. (Direct filtration plants omit this step.) The purpose of sedimentation is to enhance the filtration process by removing particulates. Sedimentation is the process by which suspended particles are removed from the water by means of gravity or separation. In the sedimentation process, the water passes through a relatively quiet and still basin. In these conditions, the floc particles settle to the bottom of the basin, while “clear” water passes out of the basin over an effluent baffle or weir. Figure 7-5 illustrates a typical rectangular sedimentation basin. The solids collect on the basin bottom and are removed by a mechanical “sludge collection” device. As shown in Figure 7-6, the sludge collection device scrapes the solids (sludge) to a collection point within the basin from which it is pumped to disposal or to a sludge treatment process. Sedimentation involves one or more basins, called “clarifiers.” Clarifiers are relatively large open tanks that are either circular or rectangular in shape. In properly designed clarifiers, the velocity of the water is reduced so that gravity is the predominant force acting on the water/solids suspension. The key factor in this process is speed. The rate at which a floc particle drops out of the water has to be faster than the rate at which the water flows from the tank’s inlet or slow mix end to its outlet or filtration end. The difference in specific gravity between the water and the particles causes the particles to settle to the bottom of the basin. -

A Lexicon of Alchemy by Martin Rulandus the Elder Translated by Arthur E. Waite John M. Watkins London 1893 / 1964 (250 Copies) A Lexicon of Alchemy or Alchemical Dictionary Containing a full and plain explanation of all obscure words, Hermetic subjects, and arcane phrases of Paracelsus. by Martin Rulandus Philosopher, Doctor, and Private Physician to the August Person of the Emperor. [With the Privilege of His majesty the Emperor for the space of ten years] By the care and expense of Zachariah Palthenus, Bookseller, in the Free Republic of Frankfurt. 1612 PREFACE To the Most Reverend and Most Serene Prince and Lord, The Lord Henry JULIUS, Bishop of Halberstadt, Duke of Brunswick, and Burgrave of Luna; His Lordship’s mos devout and humble servant wishes Health and Peace. In the deep considerations of the Hermetic and Paracelsian writings, that has well-nigh come to pass which of old overtook the Sons of Shem at the building of the Tower of Babel. For these, carried away by vainglory, with audacious foolhardiness to rear up a vast pile into heaven, so to secure unto themselves an immortal name, but, disordered by a confusion and multiplicity of barbarous tongues, were ingloriously forced. In like manner, the searchers of Hermetic works, deterred by the obscurity of the terms which are met with in so many places, and by the difficulty of interpreting the hieroglyphs, hold the most noble art in contempt; while others, desiring to penetrate by main force into the mysteries of the terms and subjects, endeavour to tear away the concealed truth from the folds of its coverings, but bestow all their trouble in vain, and have only the reward of the children of Shem for their incredible pain and labour. -

Membrane Filtration
Membrane Filtration A membrane is a thin layer of semi-permeable material that separates substances when a driving force is applied across the membrane. Membrane processes are increasingly used for removal of bacteria, microorganisms, particulates, and natural organic material, which can impart color, tastes, and odors to water and react with disinfectants to form disinfection byproducts. As advancements are made in membrane production and module design, capital and operating costs continue to decline. The membrane processes discussed here are microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). MICROFILTRATION Microfiltration is loosely defined as a membrane separation process using membranes with a pore size of approximately 0.03 to 10 micronas (1 micron = 0.0001 millimeter), a molecular weight cut-off (MWCO) of greater than 1000,000 daltons and a relatively low feed water operating pressure of approximately 100 to 400 kPa (15 to 60psi) Materials removed by MF include sand, silt, clays, Giardia lamblia and Crypotosporidium cysts, algae, and some bacterial species. MF is not an absolute barrier to viruses. However, when used in combination with disinfection, MF appears to control these microorganisms in water. There is a growing emphasis on limiting the concentrations and number of chemicals that are applied during water treatment. By physically removing the pathogens, membrane filtration can significantly reduce chemical addition, such as chlorination. Another application for the technology is for removal of natural synthetic organic matter to reduce fouling potential. In its normal operation, MF removes little or no organic matter; however, when pretreatment is applied, increased removal of organic material can occur. -

Water Filtration Background
Water Filtration Background Water Filtration It's a modern-day engineering challenge to remove human-made contaminants from drinking water. After a quick review of the treatment processes that municipal water goes through before it comes from the tap you will learn about the still-present measurable contamination of drinking water due to anthropogenic (human-made) chemicals. Substances such as prescription medication, pesticides and hormones are detected in the drinking water supplies of American and European metropolitan cities. The engineering design process can be used to design solutions for a real-world problem (contaminated water) that could affect health. Engineering Connection The water that comes from our faucets has passed through a complex system designed by many different types of engineers. Civil, chemical, electrical, environmental, geotechnical, hydraulic, structural and architectural engineers all play roles in the design, development and implementation of municipalities' drinking water supplies and delivery systems. Hydraulic engineers design systems that safely filter the water at a rate needed to supply a specific region and population. Chemical engineers precisely determine the amounts and types of chemicals added to source water for coagulation and decontamination to make the water safe to drink and not taste bad. Even so, modern pharmaceutical and agricultural practices persist in contaminating our water supplies. 1 Water Filtration Background Treating the Public Water Supply: What Is In Your Water, and How Is It Made Safe to Drink? Human Use of Freshwater Humans' Need for Clean Freshwater Water is perhaps the most important nutrient in our diets. In fact, a human adult needs to drink approximately 2 liters (8 glasses) of water every day to replenish the water that is lost from the body through the skin, respiratory tract, and urine. -

Oil Water Separators
27 OilOil WaterWater SeparatorsSeparators This section will cover coalescing oil/water separation. The concept of a basic gravity oil/water separator is simply a tank vessel that stalls the flow rate to permit gravity to separate oil from water. Oil, having a lower specific gravity than water, will naturally float on water if given time to separate. Oil The rise rate of oil to the surface is determined by Stoke’s Law. There are three main factors affect- ing the rise rate: oil droplet size, oil specific gravity and temperature. Other factors include oil/dirt particles and flow rate or turbulence. According to Stoke’s Law, a 100 micron size oil droplet will rise three inches in five minutes. When factoring in a flow rate, you can see how a simple oil/water separator will have to be quite large to give the oil enough time to rise to the surface. A 20 micron size oil droplet will rise three inches in 60 minutes. Large oil droplets are more buoyant and, there- fore, rise faster. Water Oil Layer In order to reduce the physical size of the oil/water sepa- rator, coalescors have been used successfully for many years. The concept of a coalescor is to use oleophillic (oil Oily Water Clean Water loving) media such as polypropylene or teflon. As oil and water flow through the media, oil droplets impinge on the media and coalesces on the surface. Coalescing, or bind- ing together, makes them larger and more buoyant. As Settled Solids Water you can see from the above example, a 100 micron oil particle will rise three inches twelve times faster than a 20 micron particle. -
Alchemical Theory and Practice As Overcoming the Split Between the Domain of Culture and Life Itself
Anna M. Kłonkowska Alchemical Theory and Practice as Overcoming the Split Between the Domain of Culture and Life Itself Introduction Although alchemy, its philosophical, theoretical assumptions and its practical activities is a domain beyond Bakhtin’s interests, this article is to demonstrate that one of his theories – even though originally concerning other issues – may be applied to the research in this eld. is paper refers to Bakhtin’s work Toward a Philosophy of the Act and his theory of a fundamental split between two worlds: the domain of culture and life itself, which he describes as a “split between the content or sense of a given act/activity and the histori- cal actuality of its being, the actual and once-occurrent experiencing of it” 1. It is to be demonstrated that the nature of alchemical activities and ideals may be analyzed in relation to this theory. e aim of this paper is to answer the question whether the realm of alchemists’ e!orts may be perceived as referring not only to the unity of di!erent cultural domains of sense but also to the unity of sense or meaning of an act/activity and the historical actuality of its being. The realm of alchemical ideals e popular notion of alchemy o"en regards opus alchymicum as a conscious deception: In the 1300s and 1400s continuous wars and power plays created a great demand for gold, and the swindler indulged in a lively game: Find powerful nobles 1 M.M.
