Recommended: Importance of waste water treatment
The waste water is represent of the major sources of pollution to water bodies after being discharged into rivers without proper treatment or partial treatment as it contains toxic organic substances that lead to a decline in natural water and disruption the balance of the environment ,that causes the occurrence of water pollution . Wastewater treatment processes rely on assimilation of microorganisms and enzymatic effectiveness in breakage chains carbon of soluble organic pollutants , as sewage water containing many of the compounds aliphatic ,aromatic , phenolic compounds and toluene .Which are toxic and carcinogenic compounds. (Luz and Yoav, 2008).

As well as,the magnetic field used in different intensities for killing bacteria and elimination its, they showed (Kohno et al., 2000; Ceon and Martin, 2005; Banejad and Abdolsalehi, 2009) effectiveness of the magnetic field in killing of different species of bacteria like Streptococcus mutans , Escherichia coli .
Showed a study Akbar et al. ( 2006) the efficiency of the magnetic field in the reduction of pollutants from waste water for dyes industry and demonstrated that used of the magnetic field has affected significantly on declining of concentrations COD , NH4 and PO4 by rate 40-60% of the waste water.
Proved Morteza et al.(2012) in their study the deadly impact for the lower intensities of the magnetic field on bacteria Bacillus Furthermore, showed study Yana et al.( 2013) the efficient use of the magnetic field to reduce the concentrations of phosphate from sewage at rates
This article discusses alternative antibiotics for antibiotic resistant bacteria. The author brings up the idea of using a nanotechnology-driven approach to fight against pseudomonas aeruginosa. This would be done by using nanoparticles to target and destroy pathogenic bacteria targeted selectively. This has been explored by using gold nanorods that were previously linked to antibodies that will selectively destroy the pseudomonas aeruginosa bacterium. The results show that the exposure to this type of radiation produces a reduction of the viability of the bacterial cells.
Non-chemical Water Treatment Systems: Histories, Principles and Literature Review, Loraine A Hucler, P.E., MarTech Systems, Inc., Lawrenceville, NJ, October 2002.
Background: Waste water treatment plants are essential to communities of all sizes and must work efficiently. Waste water treatment plant primary priority and responsibility is the treatment of incoming sewage water by the removal of biological and chemical wastes so it can be treated and recycled for future use. There are many government agencies and standards set forth to govern and observe the successful treatment of sewage, such as the Department of Environmental Quality, the National Pollutant Discharge Elimination System and the Clean Water Act of 1972. Compliance and constant monitoring of the treatment plant’s operations are important as they protect the surrounding community. A spill or backflow of sewage due to a complete system malfunction could potentially be detrimental to the environment and local community.
Pharmaceutical waste seems to be one of the dominant elements that are prevalent in our waters, and other aspects of the environment. These aforementioned elements are largely becoming a concern in today’s society because its effects have proven to be harmful towards our environment, and all of its existing forms of life. Through various ways, whether controllable or uncontrollable, pharmaceutical waste slowly and increasingly multiplies its presence within the environment. Additionally, it eventually trickles down into our waterways and causes a large array of damages. Some of the most common ways that this waste gets into the water includes: disposal through the drainage systems, farming fertilization methods and the maintenance of treatment plants. These methods are self-explanatory through their brief discussions, but it helps decipher whether the disposal of these dangerous wastes are intentional or not.
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
Water quality can be described as the measurement of the condition of water relative to the requirements of humans, animals and plant’s need. When we talk about water quality testing, we are highlighting a critical piece of natural observing for civil engineers in order to create a specific structure or decision. At the point when water quality is poor, it influences almost every single form of life in our planet; going from plants to animals and thereon. Hydrology, in the other hand, is the study of water. It is important to state that hydrology is a critical part for civil engineers to determine and predicting decisions that will affect our biological environment.
The industrial waste water consists of process wastes, cooling water and sanitary waste the process of segregation of cooling waste from the remaining portion will greatly reduced the load on the treatment plant. The segregation produces two types of wastes. One waste is very strong but less in volume and the second waste is weak and more or less same as the original volume. This makes the treatment process easier and reduces the difficulty of treating the total volume of waste generated. The strong waste which is low in volume can be treated specifically by selecting a suitable treatment method based on physic chemical characteristics of the strong waste.
Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the
Improvement and upgrading of wastewater treatment processes and also the need to reduce the environmental factors make the use of tertiary wastewater treatment important.
Safe water and sanitation as a basic human right, household water treatment, rainwater harvesting ... and reports from Kyoto, Madagascar, Uzbekistan, Guinea and other countries around the world.
In an effort to maintain the good condition of our rivers, wastewater works clean and purify sewage for release back into the river system once it meets the requirements for cleanliness specified in regulations set by the South African Department of Water Affairs. Proper treatment of wastewater is important to ensure that the receiving rivers into which the wastewater is discharged are not further polluted. Our rivers have the ability to cope with small amounts of pollution (assimilative capacity). However, they would be overwhelmed If the millions of litres of wastewater produced by South Africans daily were it not firstly treated before discharging back to the rivers. If wastewater is not treated adequately, negative impacts on human health and on the environment downstream of the wastewater discharge, can be observed. These impacts include harming wildlife populations (especially fish and invertebrates that live in the water), illness in people who use the river for recreational purposes (swimming and canoeing), and even contaminating drinking water sources. Pollutants commonly ass...
...e industries, textile industries are considered as one of the major sources of wastewater in ASEAN countries. Dyes are also used in industries such as rubber, paper & pulp, dye & dye intermediate industries, pharmaceutical, tannery, food technology, hair coloring, plastic, cosmetic etc. There are more than 10,000 commercially available dyes with over 7x105 tones of dyestuff being produced annually across the world2.. The textile industry consumes more than 107 kg of dye per year of which 90% ending up on fabrics3. Of this total usage 10- 15% of the dye is lost during the dyeing process and released with the effluent. Colour is contributed by phenolic compounds such as tannins, lignins (2-3%) and organic colourants (3-4%) and with a maximum contributions from dye and dye intermediates which could be sulphur/ mordant/ reactive/ cationic/ dispersed/acid/azo vat dye4.
Pollution of industrial waste water caused by the discharge of harmful chemicals and substances into water, making it unsuitable for consumption and for other purposes. Although 60 to 70% of the land is covered with water, so water bodies such as lakes, ponds, rivers, reservoirs and watercourses provide us with fresh water, keep it clean, it is a matter of survival, not only for people, but also for all other life forms. Since the industrial revolution, we have achieved many things; our manufacturing process to become more efficient and productive, science has become more sophisticated, and our lives have changed. But perhaps nothing comes without a price. All the progress and development seen in past centuries have also brought with them a wide range of problems; water pollution is one of them.
Magnetized water is also known for its efficacy in the treatment of high/low blood pressure, diabetes, kidney stones (dissolves), liver, kidney, and bladder infections. Good for HIV/AIDS patients. These diseases are as a result of disorder in the magnetic fields which can be restored through magnetic therapy e.g. magnetized water. Today most hospitals in Russia - use it for the treatment of so many ailments.
Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
